Polyamide 12 is a long-chain semi-crystalline thermoplastic material exhibiting excellent material properties. It absorbs little water, is resistant to polar and nonpolar solvents, has a low tendency to creep and high impact strength, and can be used over a wide temperature range. These properties make PA12 suitable for various demanding applications like lightweight automotive or aerospace parts, medical devices for temporary body contact, or metal-free solutions for the oil & gas industry.

The use of PA12 in 3D printing is not new. White polyamide 12 powder, also known as nylon, is the most tested material for additive manufacturing on the market1. Parts made from nylon are robust, stable for long periods of time, chemically resistant, and extremely versatile1. EOS materials based on polyamide 12 are a high-performance alternative to plastics like ABS or PA6 that have proven their value in injection molding.

The additively manufactured end products are just as strong, flexible, and durable as molded parts1. This cost-efficient general-purpose material is suitable for a variety of applications, including functional prototypes and qualified series production parts from the industry1.

Evonik Industries has established its INFINAM® PA12 nylon powders as THE multipurpose material for infinite 3D printing applications. Today, PA12 nylons manufactured by Evonik are the golden standard for powder bed fusion 3D printing of functional industrial parts2. This high-performance powders can be used in selective laser sintering (SLS), high speed sintering (HSS) as well as multi jet fusion (MJF) technologies and is expected to enable additive production of three-dimensional plastic parts for demanding 3D applications.

Evonik’s ready-to-use PA12 nylon powders offer a great attitude of properties like temperature resistance, mechanical resistance, chemical resistance, impact resistance, excellent surface resolution and feature detail, food contact compliance, or high processability in order to suite them for common powder bed fusion technologies.

Using innovative powder production technology, powder-based 3D printing processes like SLS, MJF and HSS can be used for part production without any waste of PA12 nylon powder2. Just the material which is needed for parts in one production run has to be refreshed to set up the next run.

In conclusion, Polyamide (PA) Powder Printing has significantly impacted the world of additive manufacturing. Its versatility and robustness have made it an ideal choice for various industries. As technology continues to evolve and improve, we can expect to see even more innovative uses for this remarkable material.
