Sugino Corp.’s XtenDED machine combines the subtractive and additive manufacturing capabilities of a machining center and a laser processing head.

The recently introduced machine’s AMBIT laser head, made by Hybrid Manufacturing Technologies, melts metal powder laid on a workpiece’s surface. Once the powder cools, subsequent layers are added. The process, known as laser metal deposition (LMD), is a form of directed energy deposition (DED).

The hybrid subtractive/additive system allows for increased in-process finishing of AM parts with greater accuracy, higher deposition rates, and better surface finishes, according to Sugino. “XtenDED is less wasteful than machining alone and more productive and precise than 3D printing alone. LMD uses less energy and is more controllable layer-to-layer and produces a significantly smaller heat-affected zone than plasma/wire AM systems.”

The standard 1-mm laser processing head deposits material in widths from 0.8 to 1.2 mm and has a build rate (by volume) of 10- to 25-cm³/hr.

The 5-axis, 40,000-RPM machining center comes with an HSK spindle, 13-pocket tool carousel, and an X-Y-Z stroke of 300, 400, and 200 mm, respectively.
