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 2700mm 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
