Frequently Asked Questions
MJF vs SLS?
Both nylon powder processes. MJF often favored for mechanical consistency and certain surfaces; we recommend based on geometry and finish.
Is MJF good for production?
Yes for short-run and bridge production. Very high annual volumes may still win with molding—compare on quote.
Watertight?
May need infiltrate/coat. Call sealing requirements.
Colors?
Natural gray/black typical; dye expands palette.
TPU availability?
Project-based—confirm on RFQ.
Tolerances?
Similar to other powder bed nylon; call CTQs.
Lead time?
Depends on nest and finish; ask for schedule with quantity breaks.
Certifications?
Soft capability language; no blanket aerospace AM certifications claimed.
MJF Multi Jet Fusion—service overview
MJF fuses nylon powder with agents and energy for dense, consistent parts.
Choose MJF for functional nylon and bridge production lots.
Partsproto provides MJF with finishing and overseas shipping.
- → Consistent mechanical nylon parts
- → Short-run production
- → Dyed cosmetic nylon
- → TPU flexible pilots when available
DFM tips for MJF
- •Follow minimum wall and hole guidelines for powder processes.
- •Add escape paths for trapped powder.
- •Design for dye: fine textures darken.
- •Plan inserts and threads early.
- •Freeze CAD before repeating production lots.
Inspection & QC
- ✓Density/visual sinter quality checks.
- ✓CTQ dimensions.
- ✓Color consistency for dyed lots.
- ✓Export photos on request.
Lead time & batch sizing
Efficiency improves as nests fill. Request 10 / 50 / 200 / 500 breaks for planning.
