PA12 full color (MJF)
Full-color parts with functional nylon strength; colored prototypes and end products.
What is PA12 full color (MJF)?
Color MJF systems apply coloring agents to the part while fusing PA12 powder. This gives you nylon's strength and a full-color surface in a single print. Because of the grainy matte surface, colors are not as vivid as PolyJet; in return, the parts are much more durable.
- Multicolor
- High strength
- Lightweight
Technical data
