Selective Laser Sintering (SLS) 3D Printed Materials
Nylon 12 (PA 2200): This naturally white material offers excellent strength and stiffness, good chemical resistance, and excellent long-term consistency in material properties. Meets USP Class VI requirements. Dye color options and nickel-plating finish are shown below.
Nylon 12, Smooth (PA 950 HD): A gray nylon that produces parts with an extra smooth surface finish compared to other SLS materials, excellent for highly visible parts. When combined with our vapor-smoothed finish, parts can achieve an appearance rivaling that of injection-molded parts.
Formlabs Nylon 12, Gray: A dark gray general-purpose nylon with well-balanced mechanical properties and strong dimensional accuracy and repeatability.
Nylon 12, Glass Filled (GF): This glass-filled material offers excellent strength and higher stiffness than unfilled nylon, good chemical resistance, and consistent long-term material properties. This material is naturally beige or off-white.
Formlabs Nylon 12, GF: A dark gray glass-filled variant which delivers increased stiffness, heat resistance, and dimensional stability.
Nylon 11 (EX) (Rilsan® Invent Natural): This natural white nylon 11 material offers higher impact resistance and ductility than unfilled nylon 12 variants. Nylon 11 is also sustainably sourced. Meets USP Class VI requirements.
Formlabs Nylon 11, Gray: A naturally gray nylon 11 that is ductile, impact-resistant, and has higher elongation and fatigue resistance than Nylon 12.
Nylon 12, Carbon Filled (CF) (PA 602-CF): A carbon-filled variant of SLS nylon with dark grey coloration. The carbon filler increases the material's stiffness while reducing its weight. Carbon-filled materials can be electrostatic dissipative (ESD). CF materials are ideal for elevated temperatures, and high-performance applications, and anywhere where high stiffness is required.
Nylon 12, Flame Retardant (PA 606-FR): This natural white material is the only commercially available Fire Retardant Nylon 12 that meets the FAR 25.853 60-second burn specification. Ideal for aerospace and automotive ducting, control panels, and other applications where FR is required.
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.
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.
TPU 88A (TPU 1301): A white, flexible elastomeric material with excellent abrasion resistance and tear strength. Suitable for seals, gaskets, sportsgear, footwear, and more. This material can be dyed various colors and be vapor-smoothed.
PK 5000: A high-performance PolyKetone polymer offering superior durability, wear, chemical resistance, and elevated heat stability.
Vapor Smoothing
Some SLS materials (e.g., Nylon 12, TPU 88A) can be treated with Chemical Vapor Smoothing to seal part surfaces and provide better mechanical and cosmetic properties.
