Additive manufacturing also offers suitable solutions for high-performance components

Flame retardant materials from 3D printing

The further additive manufacturing advances into the industrial production of high-performance components, the higher the demands on the materials used. In electrical engineering, aviation or rail vehicle construction, components are required that not only have to be robust, but also flame-retardant.

Jellypipe also offers you a corresponding range of additive manufacturing materials in this area. In this blog:


For the certification of flame retardant materials, the UL94 standard has become widely accepted. UL, the Underwriters Laboratories, is an independent testing organization that evaluates products for safety.

Materials suitable for heat-resistant or flame-retardant 3D printing according to UL94 V0 include:


PETG stands for polyethylene terephthalate processed with glycol. The solid, resistant material is an inexpensive all-rounder that is equipped with a halogen-free flame retardant for improved flame protection. The high-performance plastic is ideally suited for FDM printing, meets the UL94 V0 test specifications and covers a wide range of applications such as housings, covers or functional prototypes. The most cost-effective material for flame-retardant 3D printing offers heat resistance according to UNE-EN ISO 306 up to 80° C and is RoHS and REACH compliant.

About the material: PETG-FR



Onyx-FR is a carbon fiber-reinforced plastic for FDM printing that can show its advantages in applications where flame retardancy combined with low weight and increased strength are important. Onyx is a blend of nylon with 15% percent carbon short fibers, which give the high-strength thermoplastic not only excellent heat resistance but also wear-resistant surface properties. Onyx-FR offers medium heat resistance at 0.45 Mpa (80° - 150° C) and meets UL94 V0 requirements.

About the material: Onyx-FR


ULTEM 9085

ULTEM 9085 is a high-performance plastic for additive manufacturing in FDM 3D printing, which is particularly impressive due to its high heat resistance up to 153 ° C. ULTEM 9085 is a thermoplastic that is permanently flame retardant according to UL94-V0. The high-performance plastic also meets FST safety standards and is particularly suitable for lightweight construction, as the material does not deform even under heavy pressure.

About the material: ULTEM 9085


PA-FR is a flame-retardant PA12 with a sandy finish, which is used in the SLS process to produce parts that have to withstand continuous loads in daily use. PA-FR enables almost completely free design of even the most complex geometries through support-free 3D printing. In addition to excellent flame retardancy, PA-FR also offers good, flexible properties. The high-performance plastic is the preferred choice for complex geometries.

You can obtain the material on the stores via "individual inquiry".




Decision support for the selection of the appropriate flame retardant material


3D printing of components without special requirements

When it comes to reliable flame retardancy for parts that otherwise do not have any increased requirements, we recommend the use of PETG-FR. The low-cost material is a good all-rounder for fast FDM printing.


3D printing with low weight and increased strength

Onyx-FR and ULTEM 9085 are the two materials we like to use for printing high-quality components that need to impress with low weight and increased strength at the same time. ULTEM has a good strength-to-weight ratio and high thermal and chemical resistance. It also meets the requirements of industry standards for aerospace and automotive applications. Onyx-FR brings increased strength.


3D printing for special applications

Even absolute high-performance plastics reach their limits. PA-FR is our "specialist" for highly technical applications and available at Jellypipe via individual request. The great strength of PA-FR, apart from its high heat resistance, is above all its ability to realize complex geometries without support structures.


Conclusion on flame retardant materials

Flame-retardant materials from the 3D printer are indispensable in electrical engineering, aviation or rail vehicle construction. Wherever components must not start to burn under any circumstances, additive manufacturing relies on high-performance plastics. With PETG, we offer an all-round material that is suitable for most applications. For increased requirements in terms of flexibility, robustness or heat resistance, we recommend our alternatives Onyx or ULTEM 9085. For special parts that require the production of complex geometries from flame-retardant materials, we have a special material available in PA-FR. We will be happy to advise you in detail on the use of flame-retardant materials. Write to us or simply give us a call: our experts are available for you at any time.
