SLS Powders – High-Performance Materials for Industrial Powder-Bed 3D Printing

SLS (Selective Laser Sintering) powders are advanced thermoplastic materials used in powder-bed fusion 3D printers to create functional, end-use parts with excellent mechanical strength and precision. These powders are sintered layer by layer and selectively fusaed with a laser, forming dense, durable components with minimal need for support structures.

Bilby3D supplies a range of high-quality PA11, PA12, and composite powders designed for industrial SLS systems. Each formulation delivers reliable powder flow, uniform particle size, and exceptional recyclability — ensuring consistent print results across batches.

SLS printing produces parts with isotropic mechanical properties, making it ideal for engineering prototypes, functional housings, jigs, and small-series production. Available in standard nylon and specialty blends including glass-filled and carbon fibre-reinforced powders for added stiffness and temperature resistance.

Our team can assist with material selection, parameter optimisation, and post-processing guidance to help you achieve professional-grade results in every build. Bilby3D’s SLS materials are compatible with a range of open-material SLS printers and industrial systems.
