222 × 220-mm) diameter is the largest part to date built in an SLM280HL. Dual 400-W lasers made it possible to build a part of this size in a relatively short timeframe compared to conventional manufacturing.

“This part is noteworthy because of its size and the fact that it was built out of titanium in six and a half days with no process interruptions,” said Mike Hansen, SLM Solutions applications engineer. “The fact that our SLM machine can operate for that period of time without requiring cleaning or experiencing any interruptions, is, in itself, extremely signifi cant.”

SLM Solutions has increased the size of the build chamber and the build plate size to 280 × 280 mm, making the larger-sized part possible. “Advancements in 3D printing using titanium are particularly critical because it is a material that is normally very hard and thus subject to cracking due to high residual stresses, which was the real challenge. While the geometry wasn’t particularly complex the sheer mass of building something that large in titanium with the additive process was challenging,” Hansen said.
