Nylon or polyamide (PA) is a well-known material in the field of engineering and one of the most demanded nowadays for 3D printing. It is a highly versatile thermoplastic polymer that is very tough while maintaining high impact, chemical and thermal resistance. Polyamide 12 (PA12) contains twelve carbon atoms in its monomeric structure, unlike PA6 or PA11. Although their properties are similar, PA12 has the lowest moisture uptake giving better long-term results (less cracking). 3D printing with PA12 is used to replace functional injection molded parts, with very good chemical and thermal resistance.
The main feature of 3D printing with PA12 using SLS technology is that it does not require supports to support cantilevers. This is achieved by placing the construction platform at a high temperature so that the sintered powder itself has sufficient consistency. The layer height used to print PA12 is 100 microns.
– Send us your 3D file ready to print.
– If you do not have the file, send us the item and we will create the CAD file.
– If you need a design from zero, our designers will gladly prepare a quote for you.
– We will create the process file adapted to the technology and materials that will be used to produce your item.
– We prepare and condition the printer to guarantee optimum quality.
This step is key when meeting your requirements, and it is one that we are highly specialised in.
The removal of the printing support structures, heat treatments, and surface finishes (blasting, polishing, tooling) are some of the most common post processes.
The low absorption of water and moisture allows for biocompatibility in this material, which we can often see in medical applications or in connecting elements such as gears or hinges.
In addition to PA12, we offer this service in the following materials. Take a look and decide which one best suits your needs.
We design conformal cooling channels for plastic and aluminium injection inserts. With our inserts the cycle time is improved in addition to the quality of the injected item.
