Description
Medical polymer Formlabs Biomed White Resin
Medical polymer Formlabs Biomed White Resin is designed to increase the medical care quality, making modern tools available to every medical institution.
Formlabs is constantly expanding its range of materials for its 3D printers. The line of Formabs biomedical resins is designed for a wide range of applications where performance and biocompatibility are critical. BioMed Resin materials are developed and manufactured at an ISO 13485 certified plant and are compatible with conventional disinfection and sterilization methods.
Material for 3D printing in medicine
BioMed White Resin is a solid opaque biocompatible photopolymer designed for cases where prolonged skin contact or short-term contact with the patient’s mucosa is required. This unique medical polymer has been tested for pyrogenicity and acute systemic toxicity in accordance with US Pharmacopoeia standards and can be used in cases where short-term contact with tissues, bones and dentin is expected.
Models printed with BioMed White Resin can be treated with conventional solvent disinfection and sterilization methods. BioMed White Resin is manufactured at an ISO 13485 certified and USP Class VI certified facility, making it suitable for use in pharmaceuticals and drug delivery.
Printing resolution: 100 microns, 50 microns.
Final polymerization is required.
