Selective Laser Sintering (SLS) and HP Multi Jet Fusion (MJF) deliver strong, durable nylon parts with excellent mechanical properties. No support structures needed—ideal for complex geometries and functional end-use parts.
SLS (Selective Laser Sintering) uses a high-powered laser to sinter nylon powder layer by layer, fusing particles together without requiring support structures. MJF (Multi Jet Fusion), developed by HP, uses an inkjet array to apply fusing agents followed by heat to produce parts with superior mechanical properties and consistency.
Both technologies produce durable functional parts from engineering-grade nylon materials, making them ideal for low-volume manufacturing, functional prototyping, and end-use production.
