3D Printing Materials

Canada-based 3D printing materials start-up Fortis3D is breaking ground within the filament market thanks to its unique portfolio of custom filament formulations and compounds. Having made its debut earlier this year, the start-up has built up three product lines – Essential, Advanced, and Industrial – to meet the needs of hobbyists, professionals, and industry. The firm sets itself apart from other filament manufacturers with its specialty in custom formulations and compounding, which enables it to modify different resins to have “extraordinary” properties.  “As the 3D printing materials market is maturing, we want to bring value by creating innovative materials and pushing the boundaries of what current materials can do,” said Wayne Lam, Business Development Engineer at Fortis3D.  “We know the market needs more high performance, high quality, and sustainable materials and at Fortis3D that’s what we are striving for as well.” Fortis3D’s BioDuro PLA, Lignum PLA and BioDuro Metallic PLA…    read more 

Researchers at Oak Ridge National Laboratory (ORNL) have come up with a novel way of turning discarded plastic into a Fused Filament Fabrication (FFF) 3D printing material.  Using a ‘click chemistry’ reaction, the scientists’ method enables waste ABS to be turned into a ‘vitrimer,’ a polymer with the recyclability of thermoplastics and mechanical qualities of thermosets. According to the team, this “readily adoptable” process could serve as a basis for the introduction of “a closed-loop strategy,” that reduces the need for new plastics and cuts emissions tied to their production.  “We will need fundamental discoveries to overcome the challenges of increased costs and deteriorating material properties associated with recycling,” said lead author Tomonori Saito of ORNL’s Chemical Sciences Division. “Our goal was to develop an easily adoptable strategy that reuses plastic waste to create a more valuable material instead of generating fresh plastic.” The ORNL’s Sungjin Kim 3D printing using…    read more 

A group of China-based researchers have developed a new way of adding color to 3D printed parts that’s said to result in much safer products than conventional dyeing or pigmentation.  The scientists’ approach revolves around a biocompatible ink they’ve developed, which yields parts capable of changing appearance through ‘structural coloration,’ in response to heat or light stimuli. Using their material, the team say it could be possible to produce everything from wearable bio-sensors to more child-safe toys.  “We believe that [our] cholesteric liquid crystal ink can shed light on next-generation environmentally friendly 3D photonic printing,” the team explain in their paper, published in this week’s Proceedings Of The National Academy Of Sciences journal. “The ink maintains a cholesteric liquid crystalline state that gives rise to the structural color.” A 3D printed part changing color under different thermal conditions.

Formlabs announces new PU resins Kickstarting the material launches at RAPID + TCT 2022 is resin-based 3D printer manufacturer Formlabs, which has added two new polyurethane (PU) resins to its engineering resin portfolio. Designed for the production of rigid and durable parts, PU Rigid 650 Resin and PU Rigid 1000 Resin are…    read more 

Brazilian petrochemical firm Braskem has released its first line of sustainable 3D printing filaments. Made up of three filaments produced from bio-based ethylene vinyl acetate (EVA), recycled polyethylene (PE) and polypropylene (PP), the new range will be showcased at the upcoming RAPID + TCT trade show in Detroit.  “Braskem has a longstanding history of innovating and producing more sustainable bio-based polymer 3D printing filaments reaffirms our commitment to a more circular, carbon neutral future,” said Jason Vagnozzi, Braskem’s Global Commercial Director of Additive Manufacturing. “We couldn’t be more excited to present these newest additions to our 3D printing product portfolio at the RAPID + TCT 2022 conference as our clients seek more sustainability solutions for the future.” Recycled polyolefin filament with carbon fiber.

Material manufacturer Epson Atmix Co (Atmix), subsidiary of the multinational Japanese electronics firm Seiko Epson Corporation (Epson), has unveiled plans to establish a new metal powder factory.  Set to open by 2025, the complex is expected to feature metal recycling facilities, that enable scrap materials to be turned into usable alloy powders with 3D printing potential. Atmix’s announcement closely follows Epson’s own revelation that it plans to finally enter the additive manufacturing sector with a new industrial extrusion 3D printer, some eight years after first signaling its intention to do so.

Epson finally segues into 3D printing  Although Epson is primarily known for its 2D printing exploits, it has made no secret of its aspiration to expand into the 3D printing industry. As long ago as 2014, the firm’s President Minoru Usui talked openly of wanting to move into 3D printing, not just with…    read more
