3D printed bas-relief cast

The client, a lover of classical art history, needed a cast to recreate a bas-relief for display. He therefore asked us to create a series of three high-definition panels.

Problem

The main problem was to identify the best 3D printing technology that could simultaneously meet the need for a high-level surface finish and the requirement for low costs.

Solution

The choice fell on SLA printing, which, thanks to the point-by-point polymerization of the resin, offers smoother and more accurate surface finishes than other additive techniques.

The printing process is based on a concentrated beam of ultraviolet light that hardens the resin layer by layer until the boards are complete. The layer thickness used was 25 µm on the xy plane and 100 µm on the z plane.

This type of print required the addition of support meshes where the boards rested and the hollowing out of the backs of the boards to reduce material usage, thus reducing time and costs. All this was achieved without compromising the quality of the final product.

After washing the resin to remove any excess and removing the supports, the result was a precise set rich in defined details.
