What's the difference between FDM and SLA printing?

Last updated: 2026-06-29

FDM (Fused Deposition Modeling) builds parts by extruding thermoplastic filament layer-by-layer. It's ideal for functional prototypes, durable parts, and larger builds. FDM offers a wide range of engineering-grade materials like ABS, Nylon, and PETG.

SLA (Stereolithography) uses a laser to cure liquid resin into solid layers. It delivers smoother surfaces, finer details, and tighter tolerances than FDM. Perfect for presentation models, intricate designs, and high-precision parts.

Industrial SLA takes this further — Makelab uses industrial-grade SLA systems that can produce stronger resin parts and significantly larger builds (up to 1700 x 800 x 600mm for qualifying models). This combines the detail of SLA with the durability and scale previously only available through FDM.

1. Choose FDM for

Functional testing, durability, cost-effectiveness, and standard-sized parts

2. Choose SLA for

Visual models, fine details, smooth surfaces, and moderate-sized parts

3. Choose Industrial SLA for

Large-scale presentation models, strong resin parts, high-detail production parts, and projects requiring both precision and size
