FDM VS SLA: What's the Difference?

June 26, 2025

The world of 3D printing offers a wide range of technologies to turn digital designs into a physical reality, but which method best suits your business or engineering project?

Two of the most widely used technologies are Fused Deposition Modelling (FDM) and Stereolithography (SLA). While both create parts layer by layer, they differ greatly in approach, precision, and ideal applications.

To help you decide which technology aligns with your goals, we asked our Solid Print 3D technical experts to break down the differences and share their insights in this video.
