If you wanna make some abstract artwork with complex geometry, and prefer a seamless surface, then we would strongly recommend you SLA 3D printing technology. Clay modeling could not make something precisely, and other technology would require stitching or assembling.
Solution
Step 1: Check the STL files, especially the depth of sunken lines. The client ordered a solid print so it would be heavy and have no vent hole.
Step 2: Arrange the parts in software and add necessary supports. Then 3D print them with SLA Generic Resin. The layer thickness we set is 0.05mm and we control the tolerance within 卤0.1 mm.
Step 3: When printing is completed, rinse the models with IPA and post-cure them with UV. Cut off all the supports, then polish with sandpaper.
Step 4: As requested by the client, we spray the parts with specified hex colors. Then cover them with matte acrylic clear oil.
