Engineering resin ideal for applications that require mechanical strength and flame retardancy.

The Flame Retardant resin from the Formlabs portfolio of special engineering materials produces high-quality parts that are stiff (tensile modulus of 2900 MPa), and resistant to heat and deformation over time (HDT of 112 °C @ 0.45 MPa).

The Flame Retardant resin has the ability to extinguish flames on its own and is free from halogens. It also is certified by UL 94 V0 and has favorable ratings for flame, smoke, and toxicity (FST), indicating its safety for use in sectors that require those certifications.

Furthermore, parts 3D printed with the Flame Retardant resin by Formlabs have an exceptional surface finish and can be safely submitted to post-manufacturing operations such as threading, trimming and drilling, wihout damaging the parts' integrity.

The Flame Retardant resin is especially suitable for applications such as:

  • Interior parts in airplanes, automobiles, and railways.
  • Protective and internal components for consumer electronics or medical devices.
  • Custom jigs, fixtures, and replacement parts for industrial environments where high temperatures or potential ignition sources are present.

This material is compatible with the Formlabs Form 3, Form 3+, Form 3L, Form 3B, Form 3B+, Form 3BL 3D printers. The compatible resin tanks are Form 3/3B V1/V2/V2.1, as well as Form 3L/3BL V1/V2. The supported build platforms are Form 3, Form 3 2 , Form 3L, and Form 3L 2. Those printers, resin tanks and build platforms can be found here

Proper resin storage is of utmost importance for resin longevity and the quality of prints. Once opened, the resin should be handled and stores according to the manufacturer's recommendations.

The user should use adequate personal protective equipment at all times when handling the resin or solvents. More tips on printing with the Flame Retardant resin can be found in this article on the manufacturer's website.

As far as post-processing, these are the recommendations for parts 3D printed with the Flame Retardant Resin:

  • Form Wash settings: 10 minutes in IPA alcohol or 15 min in TPM. In case of using the latter, the part should be rinsed with water afterwards to ensure that all the monomethyl tripropylene glycol ether is removed.
  • Form Cure Settings: 60 minutes at 70 ºC for parts that do not require maximum heat resistance but offer higher toughness. 120 minutes at 80 ºC for parts with maximum flexural temperature under load at 0.45 MPa.
