The TruPrint 1000 metal 3D printer from Trumpf uses a laser and metallic powder to build components based on data supplied directly by a CAD program. Laser metal fusion (LMF) systems create the component, layer by layer, from metal powders with grain sizes as small as 20 microns. According to the company, this technology is ideal for parts with complex geometry such as those with internal channels and hollow spaces, and for manufacturing individual parts or short production runs economically.

Powdered stainless steel, aluminum or other weldable material is held in a supply cylinder aligned with the construction chamber and overflow receiver inside the enclosure. During the build, a layer of metal powder is applied to a substrate plate and then a 200-W laser fuses the cross-section of the geometry to the plate. After the exposure, the plate is lowered and the next layer of powder is applied. This procedure is repeated until the part is finished. The entire process takes place inside the enclosure, blanketed by protective gas, and at an oxygen content of 0.1 percent for maximum part quality.

The metal 3D printer can generate parts ranging to 100 mm in diameter and 100 mm in height. The user interface with touch screen control steps the operator through the individual phases of the process. All the components, including the laser, optics, process enclosure, filter unit and control cabinet, are integrated into the compact housing of the TruPrint 1000.

Trumpf is displaying the TruPrint 1000 alongside its TruLaser Cell 3000 five-axis laser machine at IMTS 2016.
