International science-based firm and materials producer DSM is to associate with large-scale 3D printer provider CEAD. Specializing in Fused Granulate Fabrication (FGF), a sort of fabric extrusion, the 2 entities will pursue the event of recent feedstock, tooling and end-use functions.
In accordance with Patrick Duis, Section Chief Transportation at DSM Additive Manufacturing, feedback, “By increasing our providing to FGF supplies, DSM offers producers throughout the globe maximal flexibility in selecting the fabric and expertise that most closely fits their desired utility.”
“FGF expertise permits us to make use of extremely stuffed polymers that improve the thermal, mechanical wants and the efficiency of our utility and thus takes us nearer to injection molded components.”
The ecofriendly 3D printing methodology
FGF is a relative of fused filament fabrication (FFF) that, instead of a filament, makes use of chopped, pelletized feedstock as a fabric supply. Primarily, this course of removes the “center man” of filament extrusion, as a substitute changing uncooked materials, even recycled polymers, on to the print mattress.
Although some 3D printer OEMs are bringing FGF machines and appropriate printheads to market, compared to its filament relative FGF is nowhere close to as extensively used. As defined in a 2018 article by Michigan Technological College’s (MTU) Aubrey Woern and Joshua Pearce, FGF remains to be held again by “the accessibility of low-cost pelletizers and choppers.” One potential answer, additionally explored by Woern and Pearce, is open-sourcing the development of chopping and pelletizing tools.
Nonetheless, utilized successfully, FGF has confirmed to be a extra environmentally pleasant and economical methodology of 3D printing. Additionally it is a typical alternative for large-scale polymer additive manufacturing, because of the achievable velocity of its inherent screw-extrusion system.

The superior utility of FGF
CEAD is the developer and supplier of large-format Steady Fiber Additive Manufacturing (CFAM) machines. In November 2018 the corporate launched its first system, the CFAM Prime, with marine engineering firm Royal Roos and fiberglass reinforcement specialist Poly Merchandise as the primary two clients.
As a part of the brand new collaboration, CEAD and DSM “open the door” to creating 3D printing processes that mix steady fiber composites with extremely stuffed polymers. DSM will likely be buying a 6-axis robotic 3D printer from CEAD for the aim of fabric improvement and profile optimization. The arm is offered by Italian automation firm Comau, and it’s operated utilizing Siemens software program. Additionally it is outfitted with CNC milling and scanning capabilities for submit processing following 3D printing.
Maarten Logtenberg, CEO of CEAD, concludes, “The connection between the 3D-printing expertise and the supplies which can be used within the course of, are key.”
“Via this collaboration with DSM and their understanding of the supplies, we’re in a position to totally leverage the [FGF] to its full potential.”
