Best nylon surface. HP Multi Jet Fusion. Production ready.

MJF advantages: better surface finish (Ra 6-8 vs 8-12 µm), faster print cycle (40-60% faster), consistent color with dyeing, improved detail on small features. SLS advantages: more material options (including PA12-GF, PA12-CF), slightly better for very large parts (EOS machines have larger build envelope). For most nylon prototyping and production, MJF is newer and generally better. SLS still dominant in aerospace and specialty material applications.

HP MJF production capacity: 10,000-50,000 parts per year economical. Above that, injection molding typically cheaper. Major applications use MJF for: medical wearables, automotive interior components, specialty electronics housings, consumer products where design iterates frequently. For stable high-volume designs, injection molding remains cost-effective. For evolving designs, MJF's tool-free production is advantageous.

Post-print dyeing (vat dye) provides: uniform color across all parts (unlike variable natural PA12 color), hides surface variation for better cosmetic, common industry expectation. Natural color available but shows more surface detail. Dark blue, dark grey dyeing also available. For brand-specific colors, standardization typically happens at the painting step rather than dyeing.

MJF: ±0.15 mm typical on critical features, ±0.05 mm possible on small features with careful orientation. Better than SLS for small features. Like all powder bed fusion, accuracy depends on part size and thermal conditions during print. For tighter tolerances, post-print CNC or grinding brings specific features to CNC tolerance while keeping overall MJF geometry.

Our MJF: 48 hours for simple parts (one print cycle). Typical 3-5 days for medium orders. Batch multiple customers per build for cost efficiency — shared builds typical for prototype work, dedicated builds for production orders. Rush 24-hour turnaround possible at premium.

MJF cost driven by volume (material per part) and build time. Typical small part: $15-40. Medium: $40-120. Large: $120-500. Batch of 100 parts nested in single build: per-part cost drops 30-40% vs single parts. For production volumes (500+ parts monthly), establish relationship for batch scheduling and pricing optimization.
