Formlabs Elastic 50A Resin V2 is the softest material in the Formlabs resin portfolio, rated at Shore hardness 50A to closely simulate the feel and flexibility of soft silicone. It opens up applications in SLA 3D printing that were previously reserved for silicone moulding or cast rubber processes, giving designers and engineers direct access to highly elastic printed parts.

With its outstanding elongation and recovery characteristics, Elastic 50A Resin V2 is the go-to material for wearable devices, ergonomic grips, medical anatomical models, and any component that must flex repeatedly without cracking or losing its shape. The 1L cartridge is ideal for prototyping, small-batch production, and specialist applications.

Key features

• Shore 50A hardness rating makes this the softest resin Formlabs offers, simulating the tactile and mechanical properties of soft silicone rubber.
• High elongation at break allows parts to stretch significantly and return to their original shape, suitable for repeated flexing applications.
• Ideal for gaskets, seals, ergonomic grips, over-mould prototypes, wearables, orthotic inserts, and soft anatomical training models.
• SLA-printed precision means complex geometries with undercuts and fine internal channels are achievable without tooling costs.
• Also available as Elastic 50A V2 for Formlabs Form 4 (article 210000005967) - check the MakerPoint store for the correct version for your printer.

Compatible with: Formlabs Form 3, Form 3+.
