Formlabs Rigid 4000 Resin (Form 4) 1 L

Rigid 4000 Resin is a glass-filled material that provides high stiffness and strength, similar to PEEK and PEKK thermoplastics. It is engineered for precision and produces parts with a smooth, matte finish that is highly resistant to heat and chemicals. This material is ideal for industrial parts that must withstand significant loads without bending.

This 1-litre cartridge is optimised for the Form 4 ecosystem, offering the highest tensile strength in Formlabs' engineering resin library. It is an excellent choice for functional prototypes, load-bearing components, and precise industrial tooling.

Why choose Rigid 4000 Resin?

Rigid 4000 Resin is a glass-filled material that has the highest tensile strength in our engineering resin library.

• High stiffness: resistant to deformation under various forces, pressures, and torques, making it suitable for structural parts.
• Superior tensile strength: the 69 MPa ultimate tensile strength provides the durability needed for demanding engineering applications.
• Precision and accuracy: enables the production of detailed models and accurate moulds with tight tolerances.
• Excellent surface quality: delivers parts with a smooth, matte finish that looks and feels like a finished industrial product.
• Thermal and chemical stability: maintains performance and dimensional integrity when exposed to elevated temperatures and various chemicals.

Applications for Rigid 4000 Resin:

Produce stiff and strong engineering-grade prototypes that can be load-bearing.

• Mounts and brackets: stiff, load-bearing components for mechanical assemblies.
• Jigs and fixtures: accurate and strong industrial tools for manufacturing and assembly lines.
• Thin-walled parts: maintains rigidity in delicate or thin-walled geometries where other resins might flex.
• PEEK simulation: functional prototypes that require the stiffness and thermal properties of high-performance thermoplastics.
• Industrial ducting: custom components and housings for fluid or airflow management.

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: Only compatible with the Formlabs Form 4 series resin printer and resin tank.
