This powder bed fusion process utilising thermoplastic polymers is suitable for prototyping and printing functional parts. SLS offers high levels of design freedom and high levels of accuracy, producing parts with good, consistent isotropic mechanical properties and excellent layer bonding. Printing is fully self-supporting, enabling complex geometries.
Selective Laser Sintering (SLS)
- Manufacturing capabilities from small to medium-size batch production
- Validation prototyping, model making, flexible wearables, casting cores, and chemical resistant end-use parts
- Master patterns for manufacturing technologies such as vacuum casting
- Requires post-finishing as the internal surface will be porous, while the external surface will have a grainy texture. Can be dyed.
PA650 Standard Nylon
A white, heat and chemical resistant powder resin combining strength and durability to produce strong, end use prototype parts. Heat resistant to 134ºC. Can be coloured without losing integrity.
PA615-GS Glass Filled Nylon
50% Glass sphere-filled material offering improved dimensional stability, increased stiffness and higher heat resistance.
