Puris produces largest 3-D printed titanium part

Puris LLC, Bruceton Mills, W. Va., a producer of titanium powder for additive manufacturing, has announced that it has produced what it says is the largest complex 3-D printed titanium part for commercial use. The part, printed using ExOne® binder-jetting technology, was processed to 100 percent density. Measuring 19 by 19 by 11 in. with a cross-section thickness of 0.375 in., the part weighs about 31 lbs.

“It is significant that the part was processed to full density and printed safely using affordable, available powder,” said CEO Craig Kirsch. The use of binder-jetting technology allowed Puris to print the part at room temperature, eliminating residual stress buildup and chemical-property and microstructure changes.
