SLA 3D printing model cleaning and polishing process

SLA3D printing requires a series of post-processing tasks because of the addition of a support structure, including: removing the model – soaking the alcohol – removing the support – air gun flushing – sanding. The following is a detailed introduction for you.

It is important to note that gloves should be worn when handling models. On the one hand to avoid direct contact with the skin for a long time, and on the other hand to play a protective role. Wash hands with hand sanitizer immediately after operation.

1. Remove the model
   It takes a certain skill to remove the model, and you can’t use brute force to smash it. If a rigid resin is used, it is easy to break the bottom and even break with the support, damaging the surface of the model. Be patient when removing the model, use a blade around the bottom to find the point of entry, and then slowly deepen the model to separate from the printing platform.
2. Soaking alcohol
   Put the removed model in alcohol and wait for the residual liquid resin to cure.
3. Remove support
   Soaking in alcohol for a while makes it easy to remove the support. Gap or a place that is difficult to remove needs to be removed by post-grinding.
4. Air gun flushing
   The model was rinsed with a high-pressure air gun, the residual alcohol and resin were blown off, and the model was blown dry.
5. Polishing
   The model is sanded to remove the printed texture of the support and surface that is difficult to remove. It can be colored after smoothing.
