Polyamide (PA11) (MJF) is an exceptionally versatile, strong and slightly flexible material. It can resist a small degree of impact and some pressure while being bent. Depending on the design, it can be flexible or rigid. The surface has a sandy, granular look, and is slightly porous. By using HP Multi Jet Fusion technology, your models will have a higher density and lower porosity than models produced with Selective Laser Sintering. Polyamide is the ideal choice when you need more detailed surface resolution or thinner walls than with Laser Sintering. Polyamide is a great material for beginners who want a well-priced model, extensive freedom of design, and who don’t want to be bothered too much with the limitations of the printing process.

Pricing Info
The pricing for PA 11 is based on the volume your models take up in the 3D printing machine. This includes the volume of your models and the surrounding space they require in the printer’s build chamber to ensure a successful print.
For PA 11, we charge a minimum price per ordered piece. Unlike the startup cost (which is applied to most materials), this cost vanishes when the price is higher than the minimum price. If you order two or more copies of a model, the price automatically decreases because the preparation of multiple copies can be carried out more efficiently.
Typical Use
PA 11 is fantastic for both prototypes and end-use components. It is particularly useful for applications with interlocking parts and parts with moving features, such as snap fits and living hinges.
Technology
HP Multi Jet Fusion is a powder-based technology but doesn’t use lasers. The powder bed is heated uniformly at the outset. A fusing agent is jetted where particles need to be selectively molten, and a detailing agent is jetted around the contours to improve part resolution. While lamps pass over the surface of the powder bed, the jetted material captures the heat and helps distribute it evenly.
Additional Information
- Slight variations in color may occur throughout your model and between different models. If you want a uniform look, we recommend the black dyed or black dyed + spray painted finish.
- We recommend avoiding small features (less than 3 mm) in your design.
Learning about our materials is one thing; seeing and touching them is another. That's why we've designed sample kits based on our Periodic Table of Materials.
