Selective Laser Sintering (SLS)

Why SLS?

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.

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.

SLS with PA615-GS

PA615-GS Glass Filled Nylon

50% Glass sphere-filled material offering improved dimensional stability, increased stiffness and higher heat resistance.

Technology

SINTERSTATION 2500 HiQ (3 Machines)

Lead time: 1 – 4 days
Build platform (mm): 300 x 330 x 457
Accuracy: to ± 0.3%
Layer resolution: 0.15 mm
