3D laser metal fusion printer

TRUMPF has introduced the TruPrint 1000, a 3D printer with laser metal fusion (LMF) technology.

The TruPrint 1000 uses a laser and metallic powder to build any desired component based on data supplied directly by a CAD program. LMF systems create the component layer by layer from metal powders with grain sizes as small as 20 micron.

This technology is ideal for parts that are complex in geometry, such as those with internal channels and hollow spaces, and for manufacturing individual parts or short production runs economically. The compact model appeals to both novices and those experienced in additive manufacturing technology making it a good fit for job shops, medical or dental customers, or for R&D environments. It can generate parts that are a maximum of 100mm (3.94 in) in diameter and 100mm (3.94 in) in height. The user interface with touch screen control steps the operator intuitively 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.

The supply cylinder, construction chamber and the overflow receiver are all aligned inside the enclosure. The supply cylinder contains the stainless steel, aluminum or any weldable material in powdered form. During the build, a layer of metal powder is applied to a substrate plate and then a 200W laser is used to fuse 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 per cent for maximum part quality.

With the multilaser option two TRUMPF fiber lasers, each with an output of 200 W, simultaneously scan the build area and generate up to 80 per cent more parts in the same time. Users can also ensure that parts are available more quickly and are able to maximize flexibility when processing customer orders.
