Rigid 10K Resin

Resin for Rigid, Strong, Industrial-Grade Prototypes

3D-printed parts produced with Formlabs' Rigid family of SLA resins are ideal for prototyping strong and stiff parts that resist bending and are thermally and chemically resistant or perform well under load but will brittle if pushed to extreme limits.

Rigid 10K. For industrial-grade parts to require complete rigidity

Rigid 10K is part of the rigid SLA 3D printing materials from Formlabs and is the stiffest in their engineering portfolio. This material is recommended for industrial parts that can withstand a significant load without bending. Simpler put, 3D-printed parts with Rigid 10K are tough as a rock.

Benefits of Rigid 10 K Resin

High Stiffness, High Thermal & Chemical Resistance Material

Rigid 10K is highly stiff, allowing 3D-printed parts to resist deformation under various forces, pressures and torques. In addition, it withstands high temperatures and many chemicals.

Post Processing

FORM WASH SETTINGS

DURATION

10 minutes + 10 minutes in IPA

Rigid 10K Resin contains glass particles that enhance the strength of printed parts. Use separate wash buckets to prevent these particles from sticking to parts made with other resins. If parts require two wash times, they need to undergo two wash cycles. Use clean solvent for the second wash cycle. The first cycle removes most of the resin, and the second cycle thoroughly cleans the parts.

FORM CURE SETTINGS

DURATION

60 minutes

TEMPERATURE

70 ºC

Post-curing is essential for parts printed with engineering-focused resins (such as those in the Rigid, Tough & Durable, and Flexible & Elastic families) to achieve their optimal mechanical properties and intended functionality. Rigid 10K Resin V1 has a specific recommended post-curing time. Additionally, you can optionally heat the post-cured part in a non-food oven at 90 °C for 125 minutes for a higher heat deflection temperature.

MEDIA BLASTING

Recent research and testing by the Formlabs engineering team have concluded that media blasting as an additional post-processing step that will improve Rigid 10K’s mechanical properties across every metric: tensile, flexural, and impact testing.
