No matter how complex your designs, polyamide is a great and versatile choice. The self-supporting powder needs no support structure and works equally well for fully functional prototypes or end-use parts. The PA 12 material used by Multi Jet Fusion technology has a very fine grain, resulting in parts with higher density and lower porosity than parts produced with Laser Sintering. That feature also makes PA 12 for MJF the ideal choice when you need more detailed surface resolution or thinner walls than are possible with Laser Sintering. Think crisp textures, embossing, and engraving, or labels.
|Standard lead time||5 working days (online & offline orders)|
|Standard accuracy||± 0.3% (with lower limit on ± 0.3 mm)|
|Minimum wall thickness||1 mm, but living hinges are possible at 0.5 mm|
|Layer thickness||0.08 mm|
|Maximum part dimensions||256 x 340 x 360 mm|
|Surface structure||Unfinished parts typically have a smooth surface, without visible layers, and a stone-grey color. Multi Jet Fusion parts can be sandblasted and colored/impregnated.|

The right finish and color can transform a print into a product. Multi Jet Fusion parts have a stone-grey color and a smooth finish right out of the machine, which can be further smoothed and dyed darker.
How Does Multi Jet Fusion work?
Multi Jet Fusion is a powder-based technology but does not use lasers. The powder bed is heated uniformly at the outset. A fusing agent is jetted where particles need to be selectively molten, and a detailing agent is jetted around the contours to improve part resolution. While lamps pass over the surface of the powder bed, the jetted material captures the heat and helps distribute it evenly.
