よくある質問
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.

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.
