SLA Resin 3D Printing: Why Volkswagen, Ford and Unilever Use It

Weerg staff: Apr 14, 2026

The galvanisation of an SLA resin print triples its breaking load, quadruples its stiffness, and improves flexural resistance by nearly 10 times. This is the finding that convinced Volkswagen to choose SLA 3D printing — rather than a metal printer — to produce the wheel covers for the "Type 20"...
