Prusa 3D: Printing with Prusament Resin Flex80

Flexible resins are a group of materials with low shore hardness and various uses. However, they can be challenging to print, often made from dangerous chemicals, and require washing in toxic solvents. To address these issues, Prusa3D has developed their own flexible resin called Flex80. This resin is odorless, non-toxic, and suitable for hobby and professional use. It offers fast print speed, great detail, the ability to print large objects, and easy washing with IPA.

When compared to flexible filaments, flexible resins have different properties. They can have lower shore hardness, allowing for softer and smoother models. However, flexible resins may take longer to return to their original shape compared to filaments. They are also less resilient and may crack if bent too much.

Flex80 resin is a versatile material that is easy to print and offers high performance at a low price. It has flexible and energy-damping properties, low viscosity, and is washable in IPA. The resin is virtually odorless and has high safety standards for skin irritation. It has high resolution for printing fine structures and is reliable for printing larger objects with support. The resin is easy to post-process with the Original Prusa CW1S and offers overall high performance.

After 60 minutes of curing, Flex80 resin has a tensile modulus of 17 MPa, tensile strength of 9 MPa, tensile elongation of 60%, and shore hardness of 70-80A. It can be processed by all types of SLA 3D printers but is specifically developed for printers using the 405 nm wavelength.

Flex80 resin has low toxicity and is suitable for various applications. It can be used to print models and figures with high detail and durability. The resin is also great for printing clear translucent models with minimal discoloration. It can be used in the field of microfluidics, for prototyping tires, medical models, grips, watertight seals, and rugged housing for electronic devices.
