Formlabs BioMed Flex 80A Resin (Form 4) – 1L is a firm, flexible medical-grade material engineered for the production of durable, biocompatible components. This translucent light blue resin is specifically formulated for applications requiring long-term skin contact or short-term mucosal membrane contact. Consequently, it serves as a critical resource for healthcare professionals developing functional medical devices and firm tissue models that require a hard rubber-like tactile response.

Clinical Performance of Formlabs BioMed Flex 80A Resin (Form 4) – 1L
This resin features an 80A Shore hardness, providing an ideal balance between flexibility and structural integrity for simulating firm human tissues or cartilage. Furthermore, the material is manufactured within an FDA-registered, ISO 13485 certified facility, ensuring the consistency and safety required for sterile clinical environments. Because it is optimised for the Form 4B ecosystem, it delivers high-resolution prints with smooth surfaces that enhance visual clarity during surgical planning.
Utilising the Formlabs BioMed Flex 80A Resin (Form 4) – 1L allows for the direct 3D printing of patient-specific components, effectively eliminating the need for traditional silicone moulding and reducing overall workflow times. The resin's high tear strength and durability ensure that printed models can withstand rigorous handling whilst maintaining precise anatomical geometries. Adopting this advanced photopolymer enables medical researchers and surgeons to produce high-quality, transparent prototypes that meet strict regulatory and safety benchmarks.
