Introduction

Formlabs is excited to introduce two novel materials designed for the direct 3D printing of elastomeric, biocompatible medical devices and models: BioMed Flex 80A Resin and BioMed Elastic 50A Resin. These new materials represent a significant expansion in medical application areas, particularly in the realm of anatomical modeling.

Traditionally, professionals looking to create soft anatomical models have grappled with the challenges of multi-step silicone molding processes, labor-intensive procedures resulting in limited geometries, messy outcomes, and excessive time and money spent. Alternatively, they have settled for costly contract manufacturing or rigid models.

User Experiences

DR . PRASHANTH RAVI, UNIVERSITY OF CINCINNATI
Dr. Prashanth Ravi, an Assistant Professor in the Department of Radiology at the University of Cincinnati, has utilized Formlabs' array of biocompatible resins extensively over the years. With regard to the new applications made possible by BioMed Flex 80A Resin, Dr. Ravi states, "the BioMed Flex 80A Resin is a great tool to have in that it is flexible and has all the ingredients to be biocompatible for different clinical indications, and it really gives us more options in our arsenal to help surgeons out in the field.”
