Due in part to a rapid increase in competitors to meet the quickly expanding demand of sizeable-bodiedr metal part manufacturers, metal 3D printing is getting bigger and faster. Puris, a US-based major creater of titanium powder for additive making, collaborated with ExOne to create the biggest difficult, 3D-printed titanium part for commercial use at any time 3D printed.
“There is a lot of activity in this arena and sizeable-bodiedr parts have been printed, but we believe this is the biggest difficult titanium part to be printed to date,” said Puris’ CEO Craig Kirsch. “The milestone was achieved by the combination of our team’s deep metallurgical and powder-production expertise and ExOne binder-jetting innovation. It is worthwhile that the part was processed to full density and printed safely via low-cost, on the market powder.”
The part was printed via ExOne’sbinder-jetting innovation and was processed to 100 percent density. Destined to the aerospace industry, the part measures an estimated 19” x 19” x 11”, with a cross-section thickness of 0.375-inch and a mass of approaching 31 lb (about 15 Kg).
On the other hand the actual part described in this article cannot be publicly shown, this is another 3D printed part by Puris of comparable-bodied dimensions.
The part was created on the ExOne M-Print 3D printing device, that has a print box of 32” x 20” x 16”. The work was performed Puris’s Bruceton Mills plant, under the way of the Puris metallurgy team, that comes with pioneers in spherical titanium powder gas atomization. The use of binder-jetting innovation allowed Puris to print the part at room temperature, eliminating residual stress buildup, as well as the chemical-property and microstructure changes that occur in other metal 3D-printing technologies. Mr. Kirsch explained that these are all significant aspects to commercial use of 3D-printed parts.
“We are actively working on a number of createment programs with other customers interested in delivering sizeable-bodied, 3D-printed parts into the additive making mainstream. Size is already constrained just by the printing device box itself, that presents innovation opportunities for ExOne to create sizeable-bodiedr direct-printing machines,” Kirsch introduced.
Puris has printed sizeable-bodied parts via Inconel alloy powder, as well, and is able-bodied to print with other high-performance alloys. Additive is yet a microscopic percentage of industrial metal making, but the growth rates are inversely proportional to the dimensions of the market. Bigger parts for bigger markets means that the demand for powder is expanding exponentially. Good news for companies like Puris (and its competitors).
