As shown in the pictures, the little girl and boy are dolls that commonly appeared in Chinese new year pictures. The client comes up with the idea of printing them with SLA clear resin, so it looks as if made of ice. The prints in the pics have not been chemical polished.
Solution
Step 1: Just like processing other 3D models with rich details, we first need to examine the models and make sure the layer thickness is enough for printing.
Step 2: 3D print the statues with SLA Clear Resin. It seems simple but requires a lot of engineers’ experience. We have printed tens of clear parts every day and tuned the 3D printer to the best condition.
Step 3: When printing finished, remove the supports and rinse it with IPA, then manually sand and polish it with 400-4000 grit sandpaper until the part becomes transparent.
Step 4: Spray the parts evenly with clear acrylic oil. As the oil protection layer has a thickness, the dimension of parts may be affected, so the clear parts are used just as display models, not functional ones.
