Formlabs Rigid 10K Resin (Form 3+)

Formlabs Rigid 10K resin (Form 3) 1 L

Rigid 10K resin is a highly glass-filled material designed for extreme stiffness and stability. It is the stiffest material in Formlabs' engineering portfolio, simulating the properties of glass and fibre-filled thermoplastics. This resin produces parts with a smooth, matte finish and is exceptionally resistant to heat and chemicals.

This 1-litre cartridge is ideal for industrial applications on the Form 3 ecosystem where dimensional accuracy and resistance to high pressures are critical. It serves as a high-performance alternative to traditional metal tooling for short-run injection moulds, inserts, and industrial components.

The "10K" in the name refers to the material's tensile modulus. If you need a less stiff material, try Rigid 4000 Resin.

Why choose Rigid 10K resin?

Rigid 10K resin is a high-performance material that is strong, completely stiff, and stable under significant mechanical stress.

• Extreme stiffness: the 11 GPa tensile modulus makes it highly resistant to deformation under significant force or torque.
• Superior heat resistance: features a high heat deflection temperature (HDT) of 218 °C at 0.45 MPa (post-cured), maintaining stability in high-temperature environments.
• Industrial-grade precision: captures fine details and sharp features for accurate moulds, jigs, and dies.
• Matte surface quality: prints with a smooth, non-reflective finish that is easy to polish or post-process if required.
• Chemical durability: withstands exposure to a variety of industrial fluids and chemicals without degrading or warping.

Applications for Rigid 10K resin:

Rigid 10K resin is ideal for creating rigid, strong, industrial-grade prototypes. It offers a faster and more cost-effective workflow compared to milling aluminium and steel.

• Tooling and moulds: short-run injection mould masters, inserts, and dies for thermoforming or blow moulding.
• Functional prototypes: parts that simulate glass-filled industrial plastics or require high rigidity.
• Aerospace and automotive: aerodynamic test models and components exposed to heat and fluid flow.
• Industrial manufacturing: heat-resistant jigs, fixtures, and welding tools designed for repetitive use.

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.

Note: Compatible with Formlabs Form 3, Form 3+, Form 3B, Form 3B+, and Form 3L printers.
