Laser instructions shouldn't need a visa to travel between powder bed fusion machine brands. The 3MF Consortium's new Toolpath Extension could make that possible by letting manufacturers share, inspect, and validate laser instructions without getting tangled in proprietary formats. The open specification keeps toolpaths and original part geometry together in one 3MF file, with support for variable laser settings, multiple lasers, and complex build sequences. It's particularly promising for tricky structures like graded lattices.

The secret to fixing any golf game is clearly more titanium. Golf giant Callaway is betting $15 million on a new metal 3D printing facility in Fort Worth, Texas, in a thumping vote of confidence that additive manufacturing can give its clubs a competitive edge. Set to open in mid-2027, the facility will produce custom titanium club components, exploiting 3D printing's ability to conjure up complex, performance-enhancing geometries that conventional manufacturing struggles to deliver. There's no word on which machines will be teeing off in Texas, or how many clubs Callaway plans to crank out.
