FDM vs SLA vs SLS: What's the Difference & Which Should You Use in 2026?

Walk into any conversation about 3D printing and three acronyms will come up almost immediately — FDM, SLA, and SLS. They're the three dominant technologies in additive manufacturing, and while they all produce three-dimensional objects from a digital file, they work in fundamentally different ways and produce results that vary enormously in quality, strength, detail, and cost.

Whether you're a hobbyist choosing your first printer, a designer selecting a production process, or simply someone trying to understand what all the terminology means, this guide explains...

The real question — the one that separates a laboratory curiosity from a technology that changes the world — is can we do this here, now, by the people who actually need it, at a cost that makes sense?

Metal 3D printing has been answering the...
