At 3 Zero, the most common question we get from new clients is: "Which process should I use?". The honest answer is — it depends on what the part needs to do.
FDM (Fused Deposition Modelling)
FDM is our most accessible process. It uses thermoplastic filament (PLA, ABS, PETG, TPU) and is ideal for:
- Functional prototypes that need to be handled and tested
- Jigs and fixtures for assembly lines
- Large parts where cost efficiency matters more than surface finish
Tolerance: ±0.3 mm | Best materials: ABS, PETG, TPU
SLA (Stereolithography)
SLA uses UV-cured resin for exceptional surface detail. Choose SLA when:
- Surface finish is critical (presentation models, medical devices)
- You need fine features under 1 mm
- The part will undergo visual inspection or client presentation
Tolerance: ±0.1 mm | Best materials: Standard Resin, Tough Resin, Flexible Resin
MJF (Multi Jet Fusion)
MJF is our production-grade process. PA12 Nylon parts are isotropic, functional, and batch-ready:
- 50–500 unit production runs
- Parts that need mechanical strength in all directions
- Functional assemblies like hinges, clips, and enclosures
Tolerance: ±0.1 mm | Best material: PA12 Nylon
Quick Reference
| Process | Surface | Strength | Cost | Best For |
|---|---|---|---|---|
| FDM | Medium | Good | Low | Prototypes, jigs |
| SLA | Excellent | Moderate | Medium | Visual models |
| MJF | Good | Excellent | Medium–High | Production runs |
