HOW TO CHOOSE SLS MATERIALS
A polyamide powder (Nylon 12) is our most popular and economical material. It has excellent balance of mechanical , thermal properties, excellent long-term stability and chemical resistance. It is also bio-compatible and food-safe in addition to UL-94 HB compliant.
When glass particles are added to the polyamide material, the stiffness, density, and abrasion resistance all increase. The heat deflection temperature is also much higher in PA614-GS compared to PA2200.
This is the only commercially available fire-retardant polyamide material that meets FAR 25.853 60 second burn specification. The physical properties of this material are similar to PA2200. This material is also UL94-V2 compliant. ( Only certain part thicknesses are compliant)
A metallic grey, aluminum-filled 40% polyamide 12 powder, which is characterized by its high stiffness metallic appearance. While the mechanical and thermal resistance properties are improved, the material shares more characteristics with PA12 than with aluminum.
