About Project

Here is a transparent sample part made with clear resin and SLA 3D printing technology. And it's dyed into a uniform blue-green color. It's made to display how crystal our clear prints could be. Its structure allows us to fully polish every face so there are no visible layer lines.

Solution

• Step 1: When printing transparent models, we need to focus on the structures, as polishing is highly required to make the parts clear. Sometimes the model has some blind points which are hard for sanding and polishing.
• Step 2: 3D print the model in one piece with SLA Clear Resin and our industrial SLA 3D printer. 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 is finished, remove the supports and rinse it with IPA, then manually sand and polish it with 400-4000 grit sandpaper until the model becomes transparent. Attention is necessary when cleaning the cracks.
• Step 4: Spray the part evenly with UV 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. If the client wants a frosted effect, we would sandblast the clear parts.
• Step 5: Soak the print in a dye solution for minutes.
