3D printing in PA12

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.

3D printing process with PA12

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.

3D PRINTING of parts in PA12

PA12 printed parts have the ability to withstand small degree of impact and pressure while bending. In addition, combined with the design freedom of 3D printing, Nylon printed parts can adapt their flexibility according to the wall thickness applied in the design. The aesthetic finish of the printed parts can be modified by dyeing or vapor smoothing.

The process step by step

3D File

– 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.

3D Printing

– 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.

Cleaning and post processing

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.
