ExOne certified 3D printable supplies
ExOne, the worldwide chief in industrial sand and metallic binder jetting 3D printers, has introduced the qualification of 21 new supplies to be used with its machines alongside its model new qualification system. John Hartner, ExOne’s CEO, has attributed the rising set of certified supplies to the U.S.-based firm’s in depth checklist of buyer collaborations, which incorporates partnerships with NASA and Virginia Tech.
ExOne’s rising buyer collaborations
Earlier in 2019, ExOne introduced the intensification of its collaborations to advance binder jetting expertise at a sooner fee.
Not less than 9 ExOne prospects have performed a serious function within the qualification of the ExOne supplies to date. Included on this checklist is Virginia Tech, the place Professor Chris Williams, Ph.D., has been 3D printing copper on ExOne machines since 2013. He began his work on an ExOne R2 machine, launched in 2003, and not too long ago, an Innovent+ with Triple ACT superior compaction expertise.

Main collaborations embrace H.C. Starck, who assisted in qualifying tungsten heavy alloy; World Tungsten & Powders, who assisted with tungsten carbide-cobalt, and SGL Carbon, who had a hand in qualifying Silicon Carbide infiltrated with Silicon. Different notable establishments which have contributed to the customer-qualified checklist of supplies are NASA, Oak Ridge Nationwide Laboratory, the U.S. Military, the U.S. Division of Power, and the College of Texas at El Paso.
Thanks to those collaborations, homeowners of ExOne 3D printers now have the choice to decide on between 10 single-alloy metals, 6 ceramics, and 5 composites alongside greater than 24 extra powders which have been certified for 3D printing primarily based on testing in a managed R&D setting.
ExOne and binder jetting
ExOne developed the primary iteration of their binder jetting expertise in 1996, whereby powdered materials is remodeled into dense and practical exact components at excessive speeds. An industrial nozzle deposits minuscule, exact quantities of liquid binder onto skinny layers of powder a number of instances to construct up a 3D form.
“ExOne continues to make aggressive and excellent progress in qualifying new supplies for 3D printing on our machines,” stated John Hartner. “Qualifying a brand new materials for binder jet 3D printing is complicated work that includes optimizing how supplies, machines, and processes work collectively. We want to thank our prospects and companions for his or her help in accelerating this essential work, which is enabling extra sustainable manufacturing and half designs.”
Binder jetting, like many different 3D printing applied sciences, is taken into account a sustainable methodology of metallic fabrication as a result of lack of waste generated throughout printing. On the identical time, it allows design freedom on light-weight components that may not in any other case be manufacturable.
ExOne believes the power to binder jet sure supplies, like aluminum, may have main implications for industries resembling automotive and aerospace. For that motive, ExOne is working with various manufacturing corporations to speed up the qualification of aluminum inside its new qualification system and optimize industrial 3D printing of the light-weight metallic.
“Whereas our groups can binder jet aluminum in managed R&D environments right this moment, we imagine that optimizing this materials for high-speed 3D printing will ultimately remodel how automobile and airplane components are made, making them smarter and lighter weight,” stated Rick Lucas, Chief Expertise Officer at ExOne. “Primarily based on excessive demand from , we’ve got fast-tracked improvement of this materials to be used on our machines.”

ExOne’s new qualification system
The binder jetting firm now has a brand new proprietary qualification system for supplies used with its 3D printing techniques. The three materials qualification ranges acknowledge completely different levels of fabric readiness for industrial purposes.
Third-Celebration Certified Supplies (7) have handed rigorous ExOne exams over a number of builds and have verified materials property knowledge from an impartial third get together. Supplies on this class embrace M2 instrument metal and tungsten with bronze.
Buyer-Certified Supplies (14) have been certified by ExOne prospects with their very own requirements and are presently being efficiently 3D printed for their very own purposes. Supplies on this class embrace titanium, Inconel 625 and alumina.
R&D Certified Supplies (26) have handed a preliminary qualification section by ExOne and are deemed printable, supported by ongoing improvement. Supplies on this class embrace aluminum, bronze, glass, and zirconia.
ExOne’s household of metallic 3D printers contains the Innovent+, an entry-level system used globally for R&D, design and small half manufacturing; the X1 25Professional, a mid-sized manufacturing 3D printer that’s massive sufficient for many metallic components manufactured right this moment; and the X1 160Professional, the corporate’s largest metallic 3D printer that’s anticipated to be launched later this 12 months.
The nominations for the 2020 3D Printing Business Awards are actually open. Who do you suppose ought to make the shortlists for this 12 months’s present? Have your say now.
