Formulations for 3D printing in healthcare
In the 30 years since it was introduced to the industry, photopolymerisation-based 3D printing has become a game changer for healthcare. While dental implants were among the first medical applications, today’s use cases include medical devices, implants, prosthetics and even drug delivery systems.
RAHN is a reliable supply partner of raw materials for 3D printing resins, which are used in the development of high-performance 3D photopolymers for general industrial, medical and healthcare applications. We sell our 3D printing products under the GENOMER, GENORAD, GENOCURE and GENOPOL banners.
Resilient urethane acrylates for medical device development
RAHN’s GENOMER 4267 urethane acrylate offers outstanding impact resistance and adhesion to carbon steel, aluminium and stainless steel. The product guarantees outstanding weathering performance due to its resistance to yellowing, cracking and gloss loss.
GENOMER 4267 is a reliable and long-lasting solution suitable for a range of medical device applications, delivering exceptional bonding and resistance characteristics. It can be used in combination with urethane acrylates, polyester or epoxy acrylates, and acrylate monomers.
Reactive diluents and bio-based oligomer materials
