Gray Nylon Parts

MJF - PA12

3D printed production part made with powder bed fusion at Norra Additive Manufacturing, showing fine detail accuracy and durable surface finish.

Versatile and suitable for strong and precise production parts

Gray Nylon PA12, produced with MJF technology, offers exceptional precision and mechanical strength for both prototypes and production components. It delivers high detail, dimensional accuracy, and consistent results across batches. This material is ideal for functional parts, housings, and assemblies where reliability and surface quality matter.

Frequently Asked Questions

      What advantages does MJF PA12 offer for producing durable, dimensionally stable functional parts?
    
      PA12 provides high strength, good accuracy, and excellent temperature stability, making it one of the most reliable nylon 3D printed parts materials.
    
      How does the native surface finish and detail accuracy of MJF PA12 affect the performance of housings, enclosures and mechanical assemblies?
    
      The fine matte gray nylon surface and tight detail enable precise fits and robust mechanical use.
    
      What design considerations are important when working with MJF PA12 parts with small features or complex geometry?
    
      Keep tiny features above 0.4–0.5 mm and avoid unsupported massive sections for the best results in PA12.
