Formlabs Tough 1500 Resin Certified for Skin Contact Safety

Tough 1500 Resin

Formlabs’ Tough 1500 Resin is now certified for skin contact safety in compliance with international standard ISO 10993-1, the recognised standard for manufacturing medical devices and prosthetics.

Tough 1500 Resin is supported by all Formlabs stereolithography (SLA) 3D printers – Form 2, Form 3, Form 3B, Form 3L, and Form 3BL, making it accessible to everyone. Here’s what you need to know about the new certification:

Medical applications for Tough 1500 Resin

Skin contact safety certification under ISO 10993-1 means Tough 1500 Resin can be used in biotechnology and bioengineering applications.

Tough 1500 Resin simulates the strength and toughness of polypropylene (PP), producing stiff and pliable parts that bend and spring back. It has high elongation and a moderate modulus, giving it high memory retention.

Medical applications include steam-sterilised medical devices (autoclaving), orthotics and prosthetics, parts that need to stand up to cyclic loading, connectors, packaging, cases and housings that will come into contact with skin.

Engineering applications for Tough 1500 Resin include springs, snap fits, press fits, and hinges. Skin contact safety certification makes it suitable for use as a medical-grade plastic in a wide range of specialised applications.

Tough 1500 Resin is the most resilient material in the functional resin family and should be the first choice for parts that need to bend and spring back.

Other biocompatible Formlabs Resins

Tough 1500 Resin isn’t the first Formlabs resin to be certified for skin contact under ISO 10993-1, and it won’t be the last.
