Why Choose Silicone 40A Resin
The First Accessible 100% Silicone 3D Printing Material
Silicone 40A Resin is a pure silicone, without added monomer or acrylate, enabled by Formlabs’ new patent-pending Pure Silicone Technology™. Silicone 40A Resin combines the superior material properties of cast silicone with the benefits of 3D printing.
Outstanding Elastomeric Performance
Fabricate soft, pliable, and durable parts with a 230% elongation at break and a 12 kN/m tear strength that can withstand repeated cycles of stretching, flexing, and compression. Produce highly functional silicone parts with excellent chemical resistance and thermal stability (-25°C to 125°C).
Cost-Effective Rapid Prototyping and Low Volume Manufacturing
Eliminate tooling and labor-intensive casting processes to enable custom and low-volume manufacturing of silicone parts.
Newfound Design Freedom
Create customized silicone parts with isotropic properties, fine features as small as 0.3 mm, and complex geometries that aren’t possible with casting or molding.
Fast and Easy Fabrication
Benefit from the streamlined Formlabs SLA ecosystem to produce pure silicone parts in-house, in a matter of hours.
Applications
Silicone 40A Resin is a cost and time-effective solution for fabricating functional prototypes, validation units, tooling, and small batches of silicone parts. Parts printed in Silicone 40A Resin are soft, durable, with excellent elasticity, chemical resistance, and thermal stability. They are used in industries such as consumer goods, automotive, robotics, manufacturing, and healthcare.
Consider Silicone 40A Resin for:

Workflow
Post-Processing
Washing
The foundational step in any SLA post-processing workflow is to remove any excess resin on the surface of the parts through an alcohol or ether wash.
Curing
Post-curing Engineering and Specialty Resins is essential for parts to achieve their full strength and functionality. This step completes the chemical reaction initiated during printing, transforming the part from its green state into a fully finished component.
