New industrial-grade 3D printing materials from Carbon and Roboze

Manufacturers of industrial 3D printers Carbon and Roboze have each launched a new additive manufacturing material for use with their respective 3D printing systems.

Carbon’s new EPX 86FR offering is a photopolymer resin that combines flame retardancy, functional toughness, high strength and long-term stability. Designed for both working prototypes and end-use parts, resin is best suited for applications that require self-extinguishing characteristics. This includes components such as housings, brackets and connectors for the automotive sector.

On the other hand, Roboze’s latest innovation is the Helios PEEK 2005 filament. The new material is a ceramic fiber reinforced PEEK composite offering both high strength and high temperature stability. Designed specifically for high performance metal replacement parts in critical industries such as aerospace, Helios PEEK 2005 offers a versatile blend of light weight, mechanical strength and heat resistance.

Carbon EPX 86FR Resin

According to Carbon, the new EPX 86FR resin has similar toughness and thermal stability to the company’s EPX 82 material, but with improved accuracy and higher green strength. It is suitable for a wide range of parts requiring UL 94 V-0 or FAR 25.853(a) ratings with flame retardant and self-extinguishing characteristics.

The list of target applications is long and includes electronic device battery boxes, fans, circuit board covers, automotive battery boxes, brackets, covers, fasteners, cable ties and connectors.

“We are excited to bring this new material to market, expanding the already impressive material offerings we have for our customers,” said Jason Rolland, Senior Vice President of Materials at Carbon. “EPX 86FR was created for critical industries and markets that require V-0 flame rating, high performance mechanical properties, and smooth surface quality in a reliable, consistent, high throughput printing platform.”

EPX 86FR is available to order now in North America, Europe and the UK. It is compatible with Carbon M1, M2, M3, M3 Max and L1 3D printers.

Roboze Helios PEEK 2005 Filament

Roboze’s latest offering is more than just high-strength PEEK filament. The novelty of Helios PEEK 2005 is its cut ceramic fibers, which have significantly smaller dimensions than carbon or glass fiber reinforcements. This allows the material to print very complex geometries with the thinnest walls and finest details.

The filament’s ceramic fibers also provide a single crystal structure, eliminating grain boundaries and minimizing crystallographic defects for maximum strength. Roboze states that this feature also reduces post-processing times by more than 60% compared to other composite filaments.

Thanks to the low thermal conductivity of the ceramic, Helios PEEK 2005 offers excellent thermal insulation at operating temperatures of approximately 170°C. Additionally, the resulting printed parts also exhibit low electrical conductivity, making the material ideal for applications where insulation characteristics are a necessity.

“At Roboze, we have made great strides with the use of our 3D printing technology in sectors such as aerospace, energy and motorsports. We work closely with many of these regulated industries , supporting the integration of additive manufacturing technology from prototype to production”, says Simone Cuscito, CTO of Roboze. “Helios PEEK 2005 stems precisely from the needs of these industries and is an excellent candidate for applications that require specifications of lightness, mechanical strength and heat resistance.”

Helios PEEK 2005 will be available in March on the Roboze 3D Parts Marketplace, the company’s on-demand 3D printing service.

The additive manufacturing materials sector is more active than ever. Recently, KIMYAthe additive manufacturing subsidiary of French printing and varnishing ARMORannounced its intention to extend its range of recycled filaments to new high-performance materials by 2024. As part of the third stage of ARMOR’s FIL’REC project, KIMYA is aiming for between 70 and 100% recycled materials in future high performance filaments, without affecting their properties.

Elsewhere, Infinite bending, a Germany-based smart materials developer, recently released what it claims to be the world’s first pure copper powder for SLM 3D printing. Called INFINITE POWDER Cu 01, the material has already been successfully tested on a number of standard SLM 3D printers such as the EOS M290 and Trumpf TruPrint 1000and is now commercially available.
