What are biocompatible plastics

Biocompatible plastic for 3D printing

An overview of our biocompatible plastics

By definition, biocompatible is all those materials that do not have a negative impact on living beings in their environment. In the world of (3D printable) plastics, this is particularly important for applications in medical technology. After all, it is directly related to medical products that their usability depends primarily on the fact that the organism in which they are used does not make you sick.

Of course, we at 3D Activation also take these needs into account. So today we would like to give you an overview of the biocompatible plastics among our 3D materials.

All of our PA (= polyamide) plastics, our Polyjet printing resin and the ABS variant ULTEM ™ 1010 are considered biocompatible plastics, as all of these materials are USP Class VI fulfill.

USP stands for the US pharmacopoeia

USP stands for United States Pharmacopeial Convention, which is a non-commercial organization that aims to promote public health by developing current standards for drugs and medical products. The encyclopedia United States Pharmacopeia (also abbreviated USP) published by the USP is the official pharmacopoeia of the USA and thus functions as the US counterpart to the German and European pharmacopoeia.

The USP chapter relevant here deals explicitly with the biological reactivity (and thus compatibility) of elastomers, plastics and polymers, for which special test procedures (so-called In vitro tests) were developed. Specifically, Chapters 87 and 88 of the United States Pharmacopeia deal with Class VI, which is relevant for the biocompatibility of plastics.

3 groups of biocompatible 3D printing plastics for 3D activation

Our range of biocompatible PA plastics includes the material variants PA-GF (PA powder filled with glass fibers), PA-FR (fire-resistant, according to UL fire protection class V-0), PA with wood, PA-Black (PA colored through black), Alumide (mixed with aluminum) and TPU-92A (has rubber-like properties). 3D models made of biocompatible PA plastics are particularly in demand in prosthesis construction; further fields of application are, for example, art / design and tool making.

In addition to medical technology, polyjet-printed 3D models made of biocompatible resin are used, among other things, in automotive engineering and in the aerospace industry.

ULTEM ™ 1010 is not only suitable for use in medical products, but also for architecture and dummy construction.
