Dutch multinational chemical firm Royal DSM has partnered with Ohio-based JuggerBot 3D, a 3D printing engineering and consulting agency, to discover the potential of fused granulate fabrication (FGF) know-how. The collaboration will result in the event of pellet 3D printers and supplies, supposed for manufacturing functions.
Citing a rise in demand for large-scale additive manufacturing, DSM and JuggerBot search to leverage the benefits of pellet supplies. FGF has the potential to satisfy these efficiency and measurement calls for, whereas overcoming the constraints of another 3D printing applied sciences. Hugo da Silva, VP Additive Manufacturing at DSM, explains:
“The necessity for pellet supplies and printers which are in a position to produce large-scale functions is obvious.”
“Working facet by facet with revolutionary printer producers like JuggerBot 3D permits us to create materials options whereas guaranteeing producers have entry to dependable machines.”

What’s Fused Granulate Fabrication?
FGF 3D printing will be related to the fused filament fabrication (FFF) course of in that it replaces filament with chopped, pelletized feedstock as a fabric supply. FGF is able to changing uncooked materials on to the print mattress, thus eradicating the “center man” of FFF know-how. With filler rations of as much as 50 p.c, DSM and JuggerBot imagine that FGF can meet the power, stiffness, and warmth resistance required to create massive structural functions of 3D printing.
Certainly, FGF is especially suited in the direction of large-format 3D printing in comparison with FFF know-how. Though FFF can doubtlessly be used to create massive constructions, it’s typically held again by its restricted extrusion fee, as a result of filament feed system. FGF know-how overcomes these limitations as it’s able to extruding excessive volumes of supplies by its inherent screw-extrusion system. As such, varied 3D printer OEMs are introducing FGF machines and appropriate printheads to market, nevertheless it’s nonetheless nowhere close to as extensively used as FFF.
In a 2018 paper by Michigan Technological College’s (MTU) Aubrey Woern and Joshua Pearce, they clarify that FGF is held again by “the accessibility of low-cost pelletizers and choppers.” Regardless, FGF has confirmed its potential to be a extra environmentally pleasant and economical technique of 3D printing.
Growing FGF know-how
In Might 2019, DSM introduced a partnership with large-scale 3D printer provider CEAD to pursue the event of latest feedstock, tooling and end-use functions utilizing FGF know-how. The partnership concerned DSM’s buy of a 6-axis robotic 3D printer from CEAD for the aim of fabric improvement and profile optimization. Now working with JuggerBot, DSM goals to discover “the untapped potential of FGF printing,” in an effort to meet demand for large-structural 3D printing functions amongst producers.
The event program, open to corporations excited by FGF printing, will leverage JuggerBot’s new P3-44 pellet 3D printer alongside DSM’s Arnite AM8527 (G) materials, a glass-reinforced PET product for fused granulate fabrication additive manufacturing. The fabric is designed as a cheap resolution for instruments and enormous measurement structural parts for a quantity industries together with automotive and building.

JuggerBot’s P3-44 FGF 3D printer is supplied with a 915 mm x 1,220 mm x 1,220 mm construct quantity and is a part of the corporate’s Tradesman collection of pellet extrusion methods. DSM offered its materials experience to assist JuggerBot within the improvement of the system; DSM claims that the P3-44 is able to producing components as much as 200 instances sooner than different machines.
“We’re addressing the most important obstacles to the adoption of 3D printing with fused granulate fabrication. The P3-44 is really a dependable, industrial-grade machine that permits customers to faucet right into a plethora of manufacturing supplies and scale their additive manufacturing efforts. We’re thrilled to additional align our course of experience with DSM’s materials experience and function the go-to group for corporations trying to take 3D printing to the subsequent stage,” explains Dan Fernback, Co-Founder at JuggerBot 3D.
DSM was one of many first companions to buy JuggerBot’s P3-44 3D printer, and plans so as to add extra pellet merchandise to its collection of 3D printing applied sciences. Each corporations beforehand collaborated to launch a trial program in March 2019, inviting corporations to guage engineering-grade supplies from DSM in a JuggerBot 3D printer. “Supplies or printers alone should not enough for OEMs to undertake the know-how. That’s the reason a easily operating ecosystem is so vital for additive manufacturing to be accepted on the manufacturing ground,” provides da Silva.
