These transparent penguin astronaut mascots are customed as props for Tencent's corporate video. They are printed with clear resin and dyed into four different colors to match the video theme.
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.
Step 5: Soak the parts into different dyeing solutions for hours to color them.
