LASER SINTERING MATERIALS
Selective Laser Sintering (SLS or LS) works with standard nylon 11 and nylon 12 materials and a variety of reinforced polyamides with specialized properties like improved tensile strength, heat resistance, biocompatibility, rigidity or electrostatic dissipation. Specific formulations are FST rated for use in automotive and aerospace applications, or FDA certified for food contact.
