Description

Technical Field

[0001] The present application belongs to the field of additive manufacturing, and more specifically, to a system, method and product for post-processing binder jetting parts based on fluid penetration. Background Art

[0002] As an emerging high-efficiency, high-precision additive manufacturing method, binder jetting has shown great potential and application prospects in the mass production of metal and ceramic parts. Compared with the traditional preparation process, binder jetting technology uses powder spreading technology to print green embryos. The green embryos produced have a higher porosity, and because the powder spreading technology requires a large amount of powder as support, the amount of powder required for each production is large. At present, the main binder jetting applications usually use single-component powders such as stainless steel powder, aluminum powder, etc. With the development of application needs, multi-component material applications have gradually come into people's view, but in the process of component adjustment and proportioning, a large amount of powder needs to be consumed for mixing, which brings difficulties to the development of new material systems.

[0003] As a post-processing process developed in recent years, the infiltration process provides the possibility for binder jetting to prepare multi-component materials without powder mixing. There are currently two main infiltration processes: natural infiltration and negative pressure infiltration. Natural infiltration refers to dispersing particles in a liquid and soaking the parts in it, allowing the particles to spontaneously penetrate into the parts with the liquid under capillary action. Negative pressure infiltration refers to first applying negative pressure to the infiltration environment on the basis of natural infiltration, so that the residual air in the parts is discharged, thereby making the infiltration process more complete. However, the natural infiltration process has the disadvantages of weak infiltration effect and long time consumption, and the infiltration effect of the negative pressure infiltration process is not perfect. The negative pressure process is also disadvantageous for large-scale applications. Summary of the invention

[0004] In view of the defects of the prior art, the present application provides a binder injection part post-processing system, method and product based on fluid penetration, aiming to solve the problems of poor penetration effect and long time of the existing natural penetration process.

[0005] According to one aspect of the present application, a fluid penetration-based binder jetting parts post-processing system is provided, which specifically includes a sample chamber, a liquid pump, a liquid reservoir and an ultrasonic processor, wherein the sample chamber adopts a detachable closed structure for placing parts to be processed, and the parts are made by binder jetting technology; the interior of the liquid reservoir stores a permeate obtained by mixing powder particles and a dispersed liquid, and the liquid inlet of the liquid reservoir is connected to the outlet of the liquid pump, and the liquid outlet of the liquid reservoir is connected to the sample chamber, so that the permeate is sprayed into the sample chamber under the drive of the liquid pump, thereby performing permeate post-processing on the parts to be processed; the inlet of the liquid pump is connected to the sample chamber, so as to send the remaining permeate in the sample chamber into the liquid reservoir; the ultrasonic processor is used to place the liquid reservoir, so as to ultrasonically treat the liquid in the liquid reservoir to ensure its uniform dispersion.

[0006] Through the above technical scheme conceived by the present application, compared with the prior art, the present application adopts a flow penetration method to perform post-penetration treatment on the binder sprayed parts, which can effectively improve the penetration efficiency and penetration uniformity, and has the advantages of simple structure and easy operation.

[0007] As further preferred, the binder injection part post-processing system also includes a control unit, which is connected to the liquid pump and is used to control the start and stop and flow rate of the liquid pump.

[0009] As further preferred, the binder jetting parts post-processing system further includes a temperature regulating component, which is disposed in the ultrasonic processor and is used to regulate the temperature of the penetrant.

[0010] According to another aspect of the present application, a method for post-processing a binder jetting part using the above system is provided, the method specifically comprising:

[0011] S1: Place the part to be processed in the sample chamber, add the powder particles to be infiltrated and the dispersed liquid into the liquid reservoir according to a preset ratio, and then place the liquid reservoir in the ultrasonic processor to mix the powder particles and the dispersed liquid evenly through ultrasonic treatment to obtain the permeate;

[0012] S2 starts the liquid pump and keeps the ultrasonic processor turned on, so that the permeate in the liquid reservoir is sprayed into the sample chamber under the action of the liquid pump, flows through the parts to be processed, and then is sent back to the liquid reservoir through the liquid pump. The permeate in the liquid reservoir is kept uniformly dispersed under the action of the ultrasonic processor;

[0013] S3 After the post-infiltration treatment is completed, the liquid pump is turned off and the treated parts are taken out, so that the adhesive parts are post-treated by fluid penetration.

[0014] As further preferred, in step S1, the concentration of the permeate is 3wt.% to 10wt.%.

[0015] As further preferred, in step S2, the flow rate of the permeate sprayed into the sample chamber is 200 mL / min to 500 mL / min.

[0016] As further preferred, in step S2, the temperature of the permeate is controlled at 25°C to 80°C, and the permeation time is controlled at 3 min to 10 min.

[0017] As further preferred, the method further comprises the following steps:

[0018] S4 sintering is performed after drying the processed parts, thereby completing the production of multi-component material system parts.

[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] like Figure 1 As shown, according to one aspect of the present application, a binder jetting part post-processing system based on fluid penetration is provided, which specifically includes a sample chamber 4, a liquid pump 1, a liquid reservoir 3 and an ultrasonic processor 2. The sample chamber 4 adopts a detachable closed structure for placing a part 7 to be processed, and the part 7 is made by the binder jetting technology; the inside of the liquid reservoir 3 stores a permeate obtained by mixing powder particles and a dispersed liquid, and at the same time, the liquid inlet of the liquid reservoir 3 is connected to the outlet of the liquid pump 1 through a liquid pipe 5, and the liquid outlet of the liquid reservoir 3 is connected to the sample chamber 4 through the liquid pipe 5, so that the permeate is sprayed into the sample chamber 4 under the drive of the liquid pump 1, thereby performing permeate post-processing on the part 7 to be processed; the inlet of the liquid pump 1 is connected to the sample chamber 4 through the liquid pipe 5, so as to send the remaining permeate in the sample chamber 4 into the liquid reservoir 3; the ultrasonic processor 2 is used to place the liquid reservoir 3 to perform ultrasonic treatment on the liquid in the liquid reservoir 3 to ensure its uniform dispersion.

[0031] The binder jetting parts post-processing system based on fluid penetration provided by the present application has the advantages of simple structure and convenient operation. It does not need to introduce a complex negative pressure system and negative pressure operation process, which provides the possibility for large-scale application. At the same time, the present application adopts a flow penetration method to perform post-penetration treatment on the binder jetting parts. Compared with the existing natural penetration and negative pressure penetration, it can penetrate more powder particles into the parts in a short time, and the penetration uniformity is high. In addition, the fluid penetration method proposed in the present application has the advantages of less powder consumption and the material components can be combined at will compared with the traditional powder mixing method, which has a great advantage in the material system optimization link.

[0032] Further, the binder spraying part post-processing system also includes a control unit 6, which is connected to the liquid pump 1 and is used to control the start and stop and flow rate of the liquid pump 1. In a preferred embodiment of the present application, STM32 or other microcontrollers are used. The liquid pump 1 includes but is not limited to a peristaltic pump and a diaphragm pump, and the motor can be a stepper motor or a servo motor. The control unit 6 and the liquid pump 1 can be combined into a unified adjustable speed liquid pump module.

[0033] Furthermore, the liquid reservoir 3 and the liquid pump 1 are respectively connected to the left and right ends or the upper and lower ends of the sample chamber 4 to ensure that the permeate flows completely from one end of the sample chamber 4 to the other end. The sample chamber 4 is a detachable closed structure, so under the suction of the liquid pump 1, the permeate can take out the air in the pores of the part 7 when passing through the part 7 to be treated, thereby effectively improving its permeation uniformity. In a preferred embodiment of the present application, the sample chamber 4 can be split into two upper and lower modules or two left and right modules, and the two modules can be connected by threads or bayonet, so that the liquid can flow completely from one end of the sample chamber 4 to the other end without hindrance.

[0034] Furthermore, the binder injection part post-processing system also includes a temperature regulating component, which is arranged in the ultrasonic processor 2 and can achieve the effect of regulating the temperature of the permeate by adjusting the temperature of the liquid in the ultrasonic processor 2, thereby ensuring the fluidity of the permeate while maintaining the particles dispersed evenly in the permeate.

[0035] like Figure 2 As shown, according to another aspect of the present application, a method for post-processing a binder jetting part using the above system is provided, and the method is specifically as follows:

[0036] S1: fully dry the part 7 made by the binder jetting technology, and use compressed gas to remove the excess powder remaining on the surface of the part 7, then place it in the sample chamber 4, add the powder particles to be infiltrated and the dispersion liquid into the liquid reservoir 3 according to a preset ratio, and then place the liquid reservoir 3 in the ultrasonic processor 2, and mix the powder particles and the dispersion liquid evenly by ultrasonic treatment to obtain the infiltrated liquid;

[0037] S2 starts the liquid pump 1 and keeps the ultrasonic processor 2 turned on, so that the permeate in the liquid reservoir 3 is sprayed into the sample chamber 4 under the action of the liquid pump 1, flows through the part to be processed 7, and then is sent back to the liquid reservoir 3 through the liquid pump 1. The permeate in the liquid reservoir 3 is kept uniformly dispersed under the action of the ultrasonic processor 2;

[0038] S3 After the post-infiltration treatment is completed, the liquid pump 1 is turned off and the treated parts 7 are taken out, so that the adhesive parts are post-treated by fluid infiltration.

[0039] Further, in step S1, the material used for the part 7 made by the binder jetting technology can be metal powder, ceramic powder or polymer powder. The powder particles to be infiltrated can be one or more of metal powder, ceramic powder and polymer powder. The powder particles to be infiltrated are not limited to a single type of powder, and can be a mixture of multiple types of powders, such as a mixture of metal and ceramic powder, a mixture of metal and organic powder, etc. There is no fixed limit on the particle size of the powder particles to be infiltrated, as long as they can be infiltrated into the part 7, and the available particle size ranges from nanometers to micrometers.

[0040] Furthermore, the fluid penetration process is not limited to only one penetration, and the parts that have been penetrated can be penetrated twice or even multiple times.

[0041] Furthermore, in step S1, the concentration of the permeate is 3 wt.% to 10 wt.%. If the concentration of the permeate is too low, the permeate time will be greatly prolonged, and if the concentration of the permeate is too high, the viscosity and surface tension of the liquid will increase, the fluidity will decrease, and it will be difficult to penetrate into the sample.

[0042] Furthermore, in step S2, the flow rate of the permeate into the sample chamber 4 is 200 mL / min to 500 mL / min. Too low a flow rate will not only result in a long permeation time, but also poor permeation uniformity, because the pressure brought by the low flow rate is not enough to completely expel the residual air inside the part 7. Too high a flow rate will result in excessive impact force on the part 7, and in extreme cases, it will even cause erosion on the surface of the part 7, destroying the surface quality.

[0043] Furthermore, in step S2, the temperature of the permeate is controlled at 25°C to 80°C. Since the permeate is usually water, anhydrous ethanol or other alcoholic liquids, too low a temperature will increase the viscosity of the liquid and reduce its fluidity, thereby reducing the permeation effect. Too high a temperature may even approach the boiling point of the liquid, in which case the evenly dispersed particles will separate from the liquid, resulting in permeation failure.

[0044] Furthermore, in step S2, the penetration time is controlled within 3 to 10 minutes. A lower time is not enough to allow enough particles to penetrate into the part 7. If the penetration effect is to be achieved by force, the flow rate of the penetrating liquid needs to be adjusted to a higher value, which is not good for the surface of the part 7. A longer time is also not good, because after there are enough penetrating particles inside the part 7, more particles cannot enter and will be restricted by the rough part of the surface of the part 7, resulting in the deposition of an unexpected redundant structure on the surface.

[0045] Therefore, considering the interaction between the concentration, flow rate, temperature and penetration time of the penetrant, the present application optimizes each parameter to ensure the penetration effect while avoiding the damage to the surface quality of the part 7. At the same time, the influence of different parameters on the penetration degree and penetration uniformity is consistent, which is: penetration flow rate>particle concentration>penetration time. Therefore, the optimal flow rate is 400mL / min, the concentration of the penetrant is 7.5wt.%, the penetration uniformity is best when the penetration time is 3min, and the penetration degree is optimal when the penetration time is 10min.

[0046] Furthermore, the fluid penetration process is not limited to only one penetration, and the parts that have been penetrated can be penetrated twice or even multiple times. The penetration process is not limited to processing only one part 7 at a time, and multiple parts 7 can be placed in one sample chamber 4, and the number of parts 7 chambers can be increased to increase the number of parts that can be processed.

[0047] Furthermore, the method provided by the present application also includes the following steps:

[0048] S4 dries the processed part 7 to obtain a part sample having component materials, and then sinters it to complete the production of the multi-component material system part.

[0049] According to another aspect of the present application, a multi-component material system part prepared by the above method is provided.

[0072] Comparative Example 1

[0073] The natural infiltration method in the prior art is used for treatment, and 5wt.% concentration 316L stainless steel infiltration liquid is used for infiltration. The part 7 to be treated obtained by hydroxyapatite printing is directly placed in the infiltration liquid for infiltration for 7.5 minutes. After the infiltration is completed, the infiltrated part is taken out and completely dried. The infiltrated part is placed in a heat treatment furnace under argon protection, sintered at 1250° for 3 hours, and then furnace cooled to complete the part preparation.

[0074] Comparative Example 2

[0075] The negative pressure infiltration method in the prior art is used for treatment, and 5wt.% concentration 316 infiltration liquid is used for infiltration. The beaker containing the infiltration liquid is placed in the negative pressure cylinder, and the part 7 to be treated obtained by hydroxyapatite printing is placed in the infiltration liquid and then negative pressure is started. The negative pressure value is -24kPa, and the infiltration time is 7.5min. After the infiltration is completed, the infiltrated parts are taken out and completely dried. The infiltrated parts are placed in a heat treatment furnace under argon protection, sintered at 1250° for 3h, and then cooled in the furnace to complete the part preparation.

[0076] The infiltrated parts obtained in Example 1 and Comparative Examples 1-2 were cut and the infiltration of the black 316L nanoparticles inside was observed. Figure 3It is a permeability cross-section diagram. For the sake of intuitiveness and quantification, the grayscale values ​​of the sample cross-section image are counted. In the image format, the grayscale value 0 corresponds to pure black, and the grayscale value 255 corresponds to pure white. The more 316L nanopowder that penetrates, the closer the color is to pure black, that is, the grayscale average is closer to 0. When the penetration uniformity is weak, the color of the infiltrated black 316L nanoparticles and the white hydroxyapatite matrix is ​​quite different, and the grayscale variance is large. Therefore, the higher the degree of penetration, the lower the grayscale average; the higher the penetration uniformity, the smaller the grayscale variance. For the convenience of comparison and display, (255-grayscale average) and grayscale variance are defined as the penetration degree and penetration error, respectively. The higher the penetration degree value, the better the penetration ability, and the smaller the penetration error, the higher the penetration uniformity.

[0077] Figure 3 These are the penetration results of three penetration methods. In terms of penetration degree, from low to high, they are natural penetration (81.18±4.74) < vacuum penetration (121.986±4.56) < fluid penetration (234.5253±2.63), and the penetration error from large to small is vacuum penetration (69.67±2.35) < natural penetration (48.22±3.23) < fluid penetration (8.54±1.86). The natural penetration sample is grayish white, with only a circle of black edges on the outer wall, which means that only a small amount of 316L nanoparticles have penetrated into it. Although the center of the vacuum penetration sample is also grayish white, a circle of black penetration area can be clearly observed, indicating that under the action of negative pressure, the efficiency of nanoparticles penetrating into the sample is increased, but this help is limited and cannot achieve the effect of complete penetration. The fluid penetration sample shows excellent penetration ability, and the overall color is uniform dark black, which means that a large number of nanoparticles have penetrated into the sample and are evenly distributed. Overall, fluid penetration has the best penetration ability.

[0078] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
