Puris, LLC (www.purisllc.com) has produced the largest, complex, 3D-printed titanium part for commercial use, the company said.
The part was printed using ExOneÂ® (NASDAQ: XONE) binder-jetting technology and was processed to 100 percent density.
Measuring an estimated 19 inches x 19 inches x 11 inches with a cross-section thickness of 0.375-inch, the part weighs approximately 31 pounds.
The part was produced for an aerospace customer on ExOne M-Printâ¢ 3D printer at Puris´ Bruceton Mills plant under the direction of the Puris metallurgy team.
The use of binder-jetting technology 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; these are critical aspects to commercial use of 3D-printed parts, according to Kirsch.
Puris has printed large parts using Inconel alloy powder as well, and is able to print with other high-performance alloys.
Puris, LLC produces titanium powder for additive manufacturing. The Puris team includes leaders in powder metallurgy and pioneers in spherical titanium powder gas atomization.
