[0024] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0025] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0026] The main solution of this application is: to obtain the expected range of light transmittance of the 3D printing consumable to be tested; to determine the test value of the light transmittance of the 3D printing consumable to be tested; and to determine the light transmittance test result of the 3D printing consumable to be tested based on the expected range of light transmittance and the test value.

[0027] 3D printing technology, also known as additive manufacturing, is a technology that uses digital model files as a basis and adhesive materials as consumables to construct three-dimensional models by printing layer by layer. 3D printing is typically achieved using a 3D printer. A 3D printer, also called a three-dimensional printer or stereoprinter, is a type of rapid prototyping equipment.

[0028] 3D printing technology has developed rapidly in recent years, and the quality requirements for 3D printing consumables are becoming increasingly stringent. However, in the process of realizing this application, the inventors discovered at least the following problems in the related technologies: the related technologies lack testing of consumables.

[0029] This application determines the light transmittance test results of the 3D printing consumables to be tested based on the expected value range and the test values, thereby enabling the testing of the consumables. Furthermore, light transmittance affects the color rendering effect of the printed 3D model. By testing the light transmittance, this application can reduce the occurrence of poor color rendering effects of 3D models caused by the use of consumables with unsuitable light transmittance.

[0030] Based on this, this application proposes a control method for a 3D printing consumable transmittance detection device according to the first embodiment. Please refer to [link / reference]. Figure 1 The control method includes steps S101 to S103: Step S101: Obtain the expected range of light transmittance values ​​for the 3D printing consumable to be tested; It should be noted that before conducting 3D printing filament transmittance testing, the expected range of transmittance values ​​should be reasonably set according to the material of the 3D printing filament to be tested. During the transmittance testing, the expected range of transmittance values ​​for the 3D printing filament to be tested is directly obtained. Users can input the expected range of transmittance values ​​via keyboard, mouse, or display screen.

[0031] Step S102: Determine the detection value of the light transmittance of the 3D printing consumable to be tested; In this embodiment of the application, when performing transmittance testing of 3D printing consumables, the transmittance test value of the 3D printing consumables to be tested is obtained by a 3D printing consumables transmittance testing device. Specifically, the 3D printing consumables transmittance testing device detects a first light intensity value of ambient light and a second light intensity value of light after passing through the 3D printing consumables to be tested, and determines the test value based on the first light intensity value and the second light intensity value.

[0032] The 3D printing consumable transmittance detection device includes: a light source control module, a light sensor, and a signal processing and calculation module.

[0033] The light source control module is used to provide light to the detection area. The light source control module includes a standard light source and a light-shielding structure. The standard light source includes a light source control chip, an aluminum substrate, and LED beads. The light source control chip and LED beads are mounted on the aluminum substrate and are electrically connected.

[0034] The light source control chip is a WS2812B chip, and the aluminum substrate is a 5V aluminum substrate. The 3D printing consumables transmittance detection device uses a black box design with a light-shielding structure, meaning the detection area is a black, sealed environment. This effectively eliminates ambient light interference, improves the accuracy of transmittance detection, and enhances the overall precision of 3D printing consumables transmittance detection.

[0035] A light sensor is used to detect a first light intensity value corresponding to the ambient light in the detection area, and a second light intensity value after the 3D printing filament to be tested is transmitted through the 3D printing filament when it is placed in the detection area. The light sensor can be a TSL2561 light intensity sensor, used to measure both the ambient light intensity and the light intensity transmitted through the 3D printing filament. This light sensor has advantages such as high sensitivity and a wide measurement range, enabling accurate acquisition of light intensity data and improving the accuracy of 3D printing filament transmittance detection.

[0036] Step S103: Determine the transmittance test result of the 3D printing consumable to be tested based on the expected value range and the detected value.

[0037] In this embodiment of the application, after obtaining the detection value, the transmittance detection result of the 3D printing consumable to be tested is determined based on the expected value range and the detection value. Specifically, it is determined whether the detection value is within the expected value range, and the transmittance detection result is determined based on the determination result. In a feasible implementation, step S103 may include steps S1031~S1032: Step S1031: Based on the expected value range and the detected value, determine whether the detected value is within the expected value range; Step S1032: Determine the light transmittance test result of the 3D printing consumable to be tested based on the judgment result.

[0038] In this embodiment, after obtaining the detection value, it is determined whether the detection value is within the expected value range based on the expected value range and the detection value, and the result of the determination is obtained. The light transmittance detection result of the 3D printing consumable to be tested is determined based on the result of the determination. For example, if the result of the determination is that the detection value is within the expected value range, the light transmittance detection result is determined to be qualified. If the result of the determination is that the detection value is outside the expected value range, the light transmittance detection result is determined to be unqualified.

[0039] In one feasible implementation, after step S103, the control method for the 3D printing consumable transmittance detection device may further include step S104: Step S104: Control the display device to display the transmittance detection result or the detection value.

[0040] In this embodiment of the application, when the detection value or the light transmittance detection result is obtained, the display device is controlled to display the light transmittance detection result or the detection value, so as to display the light transmittance detection result or the detection value of the 3D printing consumable to be tested through the display device. Of course, the display device can also display a qualified mark or an unqualified mark, etc.

[0041] In one feasible implementation, the control method for the 3D printing consumable transmittance detection device may further include steps S105-S106: Step S105: Obtain the type of the 3D printing consumable to be tested; Step S106: Control the memory to store the type of the 3D printing consumable to be detected and the expected value range.

[0042] In this embodiment of the application, before or after step S101, the method further includes obtaining the type of the 3D printing consumable to be tested and storing the type of the 3D printing consumable to be tested and the expected value range. That is, the control memory stores the type of the 3D printing consumable to be tested and the expected value range, so that when performing transmittance testing on other 3D printing consumables in the future, the type of the 3D printing consumable can be used to search for the type of the 3D printing consumable to be tested and the expected value range, so as to call the expected value range stored in the memory.

[0043] In one feasible implementation, the 3D printing consumable transmittance detection device 200 includes a housing, a photosensitive receiver 202, and a light source assembly 204; Please see Figure 4 as well as Figure 5 The housing defines a receiving cavity, which can be a closed detection chamber. The light source assembly 204 and the photosensitive receiver 202 are disposed within the receiving cavity. A consumable channel is defined between the photosensitive receiver 202 and the light source assembly 204. The consumable channel is part of the receiving cavity and has an inlet 209 and an outlet 210.

[0044] Understandably, consumables enter the consumables channel through the inlet 209 and leave the consumables channel through the outlet 210.

[0045] In one implementation, please refer to Figure 4 as well as Figure 5The light source assembly 204 includes a white LED, an infrared LED, or a laser emitter; and / or, the 3D printing consumable transmittance detection device 200 also includes a collimating lens disposed within a receiving cavity and fixed to the side of the light source assembly 204 facing the photosensitive receiver 202.

[0046] In this embodiment, the light source assembly 204 emits directional transmitted light, which is directed towards the consumable channel and forms a perpendicular or oblique angle of incidence with the consumable channel. When 3D printing consumables are present in the consumable channel, the directional transmitted light is directed towards the 3D printing consumables. Specifically, the directional transmitted light can be directed towards the center of the 3D printing consumables. The wavelength of the directional transmitted light can be reasonably set according to the color of the 3D printing consumables (e.g., visible light for transparent materials and near-infrared light for dark materials). The 3D printing consumables transmittance detection device 200 also includes a collimating lens disposed within the receiving cavity. The collimating lens is fixed on the side of the light source assembly 204 facing the photosensitive receiver 202. By using the collimating lens, the transmission accuracy of the directional transmitted light is improved.

[0047] In one implementation, please refer to Figure 4 as well as Figure 5 The photosensitive receiver 202 includes a photodiode or a digital light sensor; and / or, the 3D printing consumable transmittance detection device 200 also includes a filter or a light shield, which is disposed in the receiving cavity and fixed to the side of the photosensitive receiver 202 facing the light source assembly 204.

[0048] It should be noted that the digital light sensor may include the TSL series sensors. To avoid interference from ambient light, a filter or light shield can be configured on the photosensitive receiver 202. The filter or light shield is fixed on the side of the photosensitive receiver 202 facing the light source assembly 204 to reduce the interference of ambient light during the process of the photosensitive receiver 202 receiving the light emitted by the light source assembly 204.

[0049] In this embodiment, a consumable channel is defined between the photosensitive receiver 202 and the light source assembly 204. That is, the photosensitive receiver 202 and the light source assembly 204 are respectively disposed on both sides of the consumable channel. The photosensitive receiver 202 is used to receive the light emitted by the light source assembly 204. Specifically, when there is no 3D printing consumable in the consumable channel, the photosensitive receiver 202 directly receives the light emitted by the light source assembly 204. When there is 3D printing consumable in the consumable channel, the light emitted by the light source assembly 204 passes through the 3D printing consumable and is received by the photosensitive receiver 202. In order to ensure the effect of the light beam passing through the consumable and being completely projected to the photosensitive receiver 202, the central axis of the photosensitive receiver 202 can be parallel to the light source assembly 204.

[0050] In one implementation, the housing includes a first housing 201 and a second housing 206. The first housing 201 defines a first sub-cavity of the receiving cavity, the first sub-cavity including a first portion of a consumable channel, and the light source assembly 204 disposed in the first sub-cavity. The second housing 206 defines a second sub-cavity of the receiving cavity, the second sub-cavity including a second portion of the consumable channel, and the photosensitive receiver 202 disposed in the second sub-cavity. The first and second sub-cavities together form the receiving cavity, and the first and second portions of the consumable channel together form the consumable channel.

[0051] Specifically, please refer to Figure 4 The housing includes a first housing 201 and a second housing 206. The first housing 201 forms a first sub-cavity of the receiving cavity, and the second housing 206 forms a second sub-cavity of the receiving cavity. The first sub-cavity and the second sub-cavity together form the receiving cavity. The consumable channel includes a first part of the consumable channel and a second part of the consumable channel. The first sub-cavity includes the first part of the consumable channel, and the second sub-cavity includes the second part of the consumable channel. That is, the first part of the consumable channel is disposed in the first sub-cavity, and the second part of the consumable channel is disposed in the second sub-cavity. The light source assembly 204 is disposed in the first sub-cavity, and the photosensitive receiver 202 is disposed in the second sub-cavity.

[0052] The first housing 201 and the second housing 206 are designed to facilitate the production and assembly of the 3D printing consumable transmittance detection device 200. The light source assembly 204 is located in the first sub-cavity, and the photosensitive receiver 202 is located in the second sub-cavity, which facilitates the maintenance and replacement of the light source assembly 204 and the photosensitive receiver 202.

[0053] It should be noted that you should refer to [link / reference]. Figure 6 The shell formed by the first shell 201 and the second shell 206 can be rectangular in shape. The shell is made of black light-shielding ABS or aluminum alloy to enable the shell to have a light-shielding function and improve the detection stability of the 3D printing consumables transmittance detection device 200.

[0054] Additionally, it should be noted that you may refer to [link / reference]. Figure 6 The surface of the housing is provided with a mounting flange for connection to the material box 100 or the 3D printer 300, or the surface of the housing is provided with a threaded interface for connection to the material box 100 or the 3D printer 300. For example, the 3D printing consumable transmittance detection device 200 is connected to the 3D printer 300 via a mounting flange or a threaded interface to mount the 3D printing consumable transmittance detection device 200 onto the 3D printer 300, and the 3D printing consumable transmittance detection device 200 is connected to the material box 100 via a mounting flange or a threaded interface to mount the material box 100 onto the 3D printing consumable transmittance detection device 200.

[0055] In one implementation, the 3D printing filament transmittance detection device 200 further includes a rolling element 207, which is rotatably disposed within the receiving cavity and is at least partially located in the filament channel.

[0056] Furthermore, the rolling element 207 and the light source assembly 204 are located on the same side of the consumable channel, and / or the rolling element 207 is closer to the feed inlet 209 than the light source assembly 204.

[0057] In this embodiment, the rolling element 207 can be a sphere, such as a steel ball. The rolling element 207 is disposed in the receiving cavity, and at least part of the rolling element 207 is located in the consumable channel. Thus, the rolling element 207 can achieve flexible clamping of the 3D printing consumable, prevent the 3D printing consumable from shaking, maintain the stability of the detection path, and the rolling element 207 located at least part of the consumable channel can form a rolling contact point in the consumable channel, which can reduce the friction of the 3D printing consumable and thus improve the smoothness of the 3D printing consumable in the consumable channel.

[0058] In this application, the rolling element 207 can be disposed in the first sub-cavity of the receiving cavity, such that the rolling element 207 and the light source assembly 204 are located on the same side of the consumable channel, and / or the rolling element 207 is closer to the feed port 209 than the light source assembly 204, so as to timely and flexibly compress the 3D printing consumable guided through the feed port 209 to the consumable channel, thereby improving the smoothness of the 3D printing consumable passing through the consumable channel.

[0059] In one implementation, the 3D printing consumable transmittance detection device 200 further includes: a feed connector and / or an discharge connector; the feed connector is installed on the housing and defines a feed hole that communicates with the consumable channel through the feed port 209; the discharge connector is installed on the housing and defines a discharge hole that communicates with the consumable channel through the discharge port 210.

[0060] Furthermore, the feed port and / or discharge port extend in a tapering manner from the end furthest from the housing to the end closest to the housing.

[0061] In this embodiment, the housing is equipped with an infeed connector and an outlet connector. The infeed connector has an infeed hole, which communicates with the consumable channel through an inlet 209, so as to guide the 3D printing consumables into the consumable channel through the infeed hole and the inlet 209. The outlet connector has an outlet hole, which communicates with the consumable channel through an outlet 210, so as to export the 3D printing consumables from the consumable channel through the outlet 210 and the outlet hole.

[0062] It should be noted that the 3D printing consumable transmittance detection device 200 also includes a control motherboard, which is disposed within the receiving cavity. The control motherboard is communicatively connected to the photosensitive receiver 202 and is used to receive the light intensity value collected by the photosensitive receiver 202. Based on the light intensity value, it can determine the transmittance detection result corresponding to the 3D printing consumable in the consumable channel. The light intensity value output by the photosensitive receiver 202 can be an analog or digital electrical signal. The control motherboard can be disposed within the receiving cavity without affecting the position of the consumable channel and the light path between the light source assembly 204 and the photosensitive receiver 202.

[0063] Additionally, it should be noted that the 3D printing consumable transmittance detection device 200 also includes a light source motherboard 205 disposed within the accommodating cavity; the light source motherboard 205 is communicatively connected to the control motherboard and the light source assembly 204 respectively.

[0064] The light source motherboard 205 can receive light source control signals sent by the control motherboard and control the working state of the light source component 204 based on the light source control signals to precisely control the light source component 204 to light up in the detection window. Simultaneously, the light source motherboard 205 can also achieve dimming output with different brightness and frequency, allowing the light source component 204 to emit light of different brightness and frequency. The light source motherboard 205 can also perform abnormal monitoring and protection against over-temperature, over-voltage, and light source failure, providing a constant light source for stable transmittance detection. The light source motherboard 205 can be positioned within the accommodating cavity without affecting the consumable channel or the light path between the light source component 204 and the photosensitive receiver 202.

[0065] The technical solution of this application, when performing light transmittance testing, uses a light source component 204 to illuminate the 3D printing consumable in the consumable channel, and a photosensitive receiver 202 to detect the light intensity value of the 3D printing consumable, thereby realizing the detection of the 3D printing consumable and its light transmittance. This can reduce the occurrence of poor color rendering effect of the 3D model caused by the use of consumables with unsuitable light transmittance.

[0066] The 3D printing consumables transmittance detection device 200 enables optical quality prediction before 3D printing consumables are fed. It can determine the optical uniformity and purity of 3D printing consumables by detecting their transmittance before they enter the printer, and identify quality problems such as abnormal fillers, air bubbles, or recycled material contamination in advance, thereby effectively avoiding the impact of low-quality consumables on the printing process.

[0067] By placing the 3D printing consumables inspection device between the material box 100 and the 3D printer 300, away from high-temperature environments and complex structures, the inspection process is not affected by thermal interference or vibration, ensuring inspection stability and lifespan.

[0068] This application embodiment can also transmit the detection results of the 3D printing consumable detection device to the main control system in real time. Combined with the consumable identification information of the 3D printing consumable, the transmittance and consumable type can be matched and compared. Once the set threshold is exceeded, the printing can be automatically stopped, an alarm can be triggered, or the printing parameters can be adjusted to achieve closed-loop linkage of material identification and printing control.

[0069] The 3D printing consumables detection device of this application adopts a modular design, making it easy to embed into existing printing systems without requiring large-scale modifications to the material box 100 or printer structure. It is suitable for desktop and industrial-grade FDM printing equipment, possessing excellent system compatibility and scalability. This 3D printing consumables detection device supports the identification of consumables of different colors and diameters. By adjusting the light source intensity and photosensitivity, it can cover mainstream 3D printing consumables types, exhibiting broad applicability. Real-time data from the 3D printing consumables detection device can be used to construct a consumables transmittance database, mapping it to parameters such as production batch and label ID, facilitating consumables screening, quality traceability, and consistency management in large-scale printing tasks. Figure 7 As shown, the 3D printing consumable detection device 200 can be positioned between the material bin 100 and the 3D printer 300. The consumable enters the 3D printing consumable detection device 200 from the material bin 100, and then enters the 3D printer 300.

[0070] This application also proposes a 3D printing filament feeding system; please refer to [link / reference].

The specific structure of the 3D printing consumable transmittance detection device 200 is as described in the above embodiments. Since this 3D printing system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0071] The material box 100 is used to hold the material tray, and the material tray is used to hold the consumables. The 3D printing consumables transmittance detection device 200 is fixed to the material box 100. For example, the 3D printing consumables transmittance detection device 200 is fixedly connected to the material box 100 through a mounting flange or threaded interface, so as to fix the 3D printing consumables transmittance detection device 200 on the material box 100.

The specific structure of the 3D printing consumable transmittance detection device 200 is as described in the above embodiments. Since this 3D printing system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0073] The 3D printing consumable transmittance detection device 200 is fixed to the 3D printer 300. For example, the 3D printing consumable transmittance detection device 200 is connected to the 3D printer 300 via a mounting flange or threaded interface to fix the 3D printing consumable transmittance detection device 200 onto the 3D printer 300. The 3D printer 300 includes a print head 301 and a printer housing 302; the discharge port 210 of the 3D printing consumable transmittance detection device 200 is connected to the print head 301 of the 3D printer 300.

[0074] After the 3D printing filament enters the 3D printing filament transmittance detection device 200, the control motherboard issues a detection start command. The light source motherboard 205 illuminates the light source component 204 according to the control motherboard command. The light penetrates the 3D printing filament and is received by the photosensitive receiver 202. The photosensitive receiver 202 feeds back the received signal to the control motherboard. The control motherboard performs digital-to-analog conversion, filtering, and calculation on the signal to generate a standard value (transmittance) related to transmittance. The control motherboard compares this value with a preset threshold: if the transmittance is within the normal range, the 3D printing system continues printing; if the transmittance is abnormal (such as misuse of transparent filament), the 3D printing system can automatically pause printing, output an alarm prompt, or automatically adjust parameters such as nozzle temperature and printing speed according to the material characteristics of the 3D printing filament to improve compatibility.

[0075] The 3D printing system of this application embodiment can support a variety of materials (such as PLA, ABS, PETG, etc.) and different filament diameters (such as 1.75mm). The detection module has a compact structure and can be directly integrated into the standard filament feeding channel between the material box 100 and the 3D printer 300 without modifying the original equipment structure.

[0076] The control method for a 3D printing consumable transmittance detection device proposed in this embodiment obtains the expected range of transmittance values ​​for the 3D printing consumable to be tested, then determines the detected transmittance value of the 3D printing consumable to be tested, and finally determines the transmittance detection result of the 3D printing consumable to be tested based on the expected range and the detected value. This achieves transmittance detection of 3D printing consumables, and improves the accuracy and efficiency of transmittance detection of 3D printing consumables. By determining the transmittance detection result of the 3D printing consumable to be tested based on the expected range and the detected value, the consumable can be tested. Furthermore, transmittance affects the color rendering effect of the printed 3D model. This application, by detecting transmittance, can reduce the occurrence of poor color rendering effects of 3D models caused by the use of consumables with unsuitable transmittance.

[0077] In one feasible implementation, step S102 may include steps S201 to S203: Step S201: Obtain the first illuminance value of the ambient light; Step S202: Obtain the second light intensity value of the light after passing through the 3D printing consumable to be tested; Step S203: Determine the detection value based on the first light intensity value and the second light intensity value.

[0078] In this embodiment, when performing transmittance detection of 3D printing consumables, a first ambient light intensity value is obtained; that is, before the 3D printing consumables to be tested are placed in the 3D printing consumables transmittance detection device, the first ambient light intensity value is obtained through the 3D printing consumables transmittance detection device. In a feasible implementation, step S201 may include steps S2011~S2013: Step S2011: When the 3D printing consumable to be tested is located outside the space between the light source and the light sensor, control the light source to emit light; Step S2012: Control the light sensor to detect the first light intensity value; Step S2013: Obtain the first light intensity value detected by the light sensor.

[0079] In this embodiment, the 3D printing consumable transmittance detection device includes at least a light source and a light sensor. When the 3D printing consumable to be tested is located outside the space between the light source and the light sensor, the light source of the 3D printing consumable transmittance detection device is controlled to emit light, and the light sensor is controlled to detect a first light intensity value. The first light intensity value detected by the light sensor is obtained, and then the first light intensity value of the ambient light is obtained when the 3D printing consumable to be tested is located outside the space, so as to accurately obtain the first light intensity value and improve the accuracy of transmittance detection of the 3D printing consumable to be tested.

[0080] Next, the 3D printing filament to be tested is placed in a 3D printing filament transmittance testing device, and the second illumination intensity value of the light transmitted through the 3D printing filament to be tested is obtained through the 3D printing filament transmittance testing device. In a feasible embodiment, step S202 may include steps S2021~S2023: Step S2021: When the 3D printing consumable to be tested is located in the space between the light source and the light sensor, control the light source to emit light; Step S2022: Control the light sensor to detect the second light intensity value; Step S2023: Obtain the second light intensity value detected by the light sensor.

[0081] In this embodiment, after obtaining the first light intensity value, the 3D printing consumable to be tested is placed in the space between the light source and the light sensor of the 3D printing consumable transmittance detection device. With the 3D printing consumable to be tested located in the space between the light source and the light sensor, the light source of the 3D printing consumable transmittance detection device is controlled to emit light. Then, the light sensor of the 3D printing consumable transmittance detection device is controlled to detect the second light intensity value, and the second light intensity value detected by the light sensor is obtained to accurately obtain the second light intensity value, thereby improving the accuracy of the transmittance detection of the 3D printing consumable to be tested.

[0082] After obtaining the first light intensity value and the second light intensity value, the detection value is determined based on the first light intensity value and the second light intensity value. In one feasible implementation, step S203 may include steps S2031~S2032: Step S2031: Determine the ratio of the first light intensity value to the second light intensity value based on the first light intensity value and the second light intensity value; Step S2032: Determine the detection value based on the ratio.

[0083] In this embodiment of the application, after obtaining the first light intensity value and the second light intensity value, the ratio of the first light intensity value and the second light intensity value is calculated, and the detection value is determined based on the ratio. For example, the ratio is used as the detection value to accurately obtain the detection value.

[0084] In one feasible implementation, the control method for the 3D printing consumable transmittance detection device may further include step S204: Step S204: Control the memory to store at least one of the detection value, the transmittance detection result, the first light intensity value, and the second light intensity value.

[0085] In this embodiment, after obtaining the detection value, the control memory stores at least one of the detection value, transmittance detection result, first light intensity value and second light intensity value, so as to facilitate re-inspection based on the stored information.

[0086] In one feasible implementation, after step S203, the control method for the 3D printing consumable transmittance detection device may further include step S205: Step S205: Obtain the maximum detectable transmittance value and the minimum detectable transmittance value of the 3D printing consumable transmittance detection device; Step S203 includes: Step S2033: Determine the detection value based on the first light intensity value, the second light intensity value, the maximum detectable transmittance value, and the minimum detectable transmittance value.

[0087] In this embodiment, after obtaining the first light intensity value and the second light intensity value, the maximum detectable light transmittance value and the minimum detectable light transmittance value of the 3D printing consumable light transmittance detection device are obtained. Based on the maximum detectable light transmittance value, the minimum detectable light transmittance value, the first light intensity value, and the second light intensity value, the detection value is determined. For example, the ratio of the first light intensity value to the second light intensity value is first determined, and then the value is corrected based on the comparison between the maximum detectable light transmittance value and the minimum detectable light transmittance value to obtain the detection value.

[0088] It should be noted that, ideally, the maximum transmittance value of a 3D printing consumable transmittance testing device is 100%, and the minimum transmittance value is 0%. However, in reality, the maximum detectable transmittance value of a 3D printing consumable transmittance testing device is 90%, and the minimum detectable transmittance value is 10%. Therefore, the test results need to be adjusted proportionally. For example, the difference between the maximum and minimum detectable transmittance values ​​can be used as a correction value, and the above ratio can be multiplied by this correction value to obtain the test value.

[0089] This application embodiment obtains a first light intensity value of ambient light, then obtains a second light intensity value of light after passing through the 3D printing consumable to be tested, and then determines the detection value based on the first light intensity value and the second light intensity value, thereby realizing the light transmittance detection of 3D printing consumables. The accuracy and efficiency of 3D printing consumable light transmittance detection are improved by using a 3D printing consumable light transmittance detection device.
