Description

Technical Field

[0001] This invention belongs to the field of 3D printing technology, specifically relating to a cleaning and drying device for photopolymer 3D printed models and its operating method. Background Technology

[0002] When printing models, due to the nature of the process, photopolymer 3D printers often leave some uncured resin residue on the model surface. Post-processing is necessary for proper use, including cleaning and drying. Cleaning uses a specific solution to dissolve and remove residual resin from the model surface. Drying uses a fan, air gun, or other methods to quickly remove the remaining solution. Only through cleaning and drying can the performance of the subsequently cured model be improved, less prone to cracking, have an extended shelf life, and ensure its quality and stability. Currently, the machines on the market can be categorized by function as follows: 1. Machines with only cleaning function. When using this machine, the user needs to immerse the model in the cleaning container. The machine uses a rotating impeller, shaking the container, or ultrasonic waves to dissolve the residual resin on the model's surface, thus completing the cleaning process.

[0003] 2. Device with only drying function. When using it, the user needs to place the cleaned model at the air outlet of the air outlet device, and use the rapid airflow to remove the specific solution remaining on the surface of the model, thereby completing the drying process.

[0004] 3. An all-in-one machine with cleaning and other functions. Users need to place the model into the internal container of the machine, and the surface of the model will be rinsed by rotating sprayers to complete the cleaning process.

[0005] After in-depth analysis of the above three types of machines or devices, the following drawbacks are identified: 1. Machines with only cleaning function: 1. **Cumbersome Operation:** After cleaning, a significant amount of residual solution remains on the model surface during the transfer to the drying device. This requires a device to catch the dripping liquid, and the device itself needs subsequent cleaning, resulting in low efficiency and increased complexity and time costs. 2. **Impeller Rotation Mode:** The impeller at the bottom of the container rotates, causing the cleaning liquid inside to circulate. However, its working principle limits the design space of the cleaning container, making it suitable only for small to medium-sized models and unsuitable for large models. 3. **Shaking Container Mode:** Shaking the entire container moves the liquid and model together. This is only suitable for small to medium-sized models. For large models, significant adjustments to the power source and overall size are required, greatly increasing costs. Furthermore, the erratic movement of the model can easily damage its structure, especially delicate details, potentially causing irreparable damage. 4. **Ultrasonic Mode:** An ultrasonic generator emits ultrasonic waves that vibrate in contact with the liquid, achieving cleaning. This is also only suitable for small to medium-sized models. For large models, significant adjustments to the power source and overall size are required, greatly increasing costs. Devices with only drying function: 1. Require the transfer of pre-processed models to the drying device, resulting in low work efficiency; 2. Single airflow direction, requiring manual adjustment to complete the multi-angle, multi-directional drying process. All-in-one machine with cleaning and other functions: 1. Has cleaning but no drying function, leading to defects in the post-processing of models, potentially resulting in incomplete cleaning or whitening of the surface after curing; 2. Rotary spray cleaning mode: Whether the model is fixed and the spray arm rotates or the model rotates and the nozzle is fixed, the water trajectory is fixed, thus failing to completely cover all detailed areas of the model surface, leading to incomplete cleaning in certain areas. This is especially true for complex, multi-supported models, where the probability of thorough internal cleaning is greatly reduced, and its cleaning capability for hollow models is also limited.
