HP 5200 build size.
Ra 3-6 µm
Slightly smoother than SLS as-built.
FAQ
Why MJF over SLS?
Faster build speed, better consistency, better surface finish, slightly lower cost at production.
Material limitations?
Currently PA12 only (PA11 emerging). SLS has wider material range (TPU, GF nylon).
Tolerance?
±0.2 mm typical. ±0.05 mm with care + post-machining.
Color options?
Dyed black standard. Color printing emerging via additional agents.
Production-grade?
Yes — MJF parts in production for medical, automotive, aerospace.
Cost?
Volume-based. Pack multiple parts. ~$5-30 per cubic inch typical.
