Selective Laser Sintering (SLS) 3D Printed Materials
- SLS Nylon 12 (PA 2200): This material offers excellent strength and stiffness, good chemical resistance with excellent long-term consistency in material properties. Meets USP Class VI requirements. (View spec sheet)
- SLS Nylon 12, Glass Filled (GF): This glass-filled material offers excellent strength and higher stiffness than unfilled nylon, good chemical resistance with excellent long-term consistency in material properties. (View spec sheet)
- SLS Nylon 11 (EX) (Rilsan® Invent Natural): This natural white nylon 11 material has higher impact resistance and ductility compared to nylon 12 unfilled variants. Nylon 11 is also sustainably sourced. Meets USP Class VI requirements. (View spec sheet)
- SLS Nylon 12, Carbon Filled (CF) (PA 602-CF): A carbon-filled variant of SLS nylon with dark grey coloration. The carbon filler increases the stiffness of the material while decreasing the weight. Carbon-filled materials can be electro-static dissipative (ESD). CF materials are ideal for elevated temperatures, and high-performance applications, and anywhere where high stiffness is required.

- SLS Nylon 12, Aluminum Filled (AF) (PA 605-A): An aluminum-filled material with a pleasant metallic grey finish has good stiffness and thermal conductivity. AF materials are great for showcase models, rapid tooling, and fixtures. The material is not electrically conductive. (View spec sheet)
- SLS Nylon 12, Mineral Filled (HST) (PA 620-MF): This mineral-filled nylon 12 variant provides exceptional stiffness and dimensional stability even at high heat. MF materials have an HDT of 363° F (184° C). Mechanical properties are anisotropic due to mineral orientation on the XY plane. (View spec sheet)
SLS Material Comparison Chart
Above: This chart compares key aspects of elongation, flexibility, and heat deflection temperatures across different SLS materials and blends. Note that added fillers typically decrease elongation before breaking, but can increase rigidity. Nylon 11 melts at a higher temperature than nylon 12, giving it a slightly higher HDT for the flexible material.
SLS nylon parts can be enhanced with Chemical Vapor Smoothing to seal the surfaces and provide better mechanical and cosmetic properties.
