Formlabs Silicone 40A was developed to deliver an elastic 3D printing experience that is close to the performance of traditional silicone materials. With a hardness of around 40A Shore, this material combines deformability, comfort to the touch, and resilience, making it perfect for applications that require soft yet strong parts.
This resin makes it possible to create soft gaskets, shock-absorbing cells, flexible components and models that require a high capacity to deform and return to the original shape. The surface is uniform and ready to use, with defined details typical of SLA printing.
| Feature | Why it matters |
|---|---|
| High softness (~40A) | Simulates soft elastic materials with excellent touch behavior |
| Fast | Parts regain shape after repeated warping |
| Compressive | Ideal for elements that need to cushion or adapt |
| SLA workflow | Easy to print, wash, and post-cure with Formlabs profiles |
| Flexible and durable | Combines convenience and reliability in many applications |
Formlabs Silicone 40A brings a new dimension to elastic 3D printing: it combines softness, resilience, and durability in a material that is easy to print and machine. If you need parts that not only deform but take shape with comfort and reliability, Silicone 40A is the solution that guarantees you real performance for prototypes and functional applications.
