Trumpf presents a fast and productive medium-format 3D printing system for metal components. TruPrint 5000 works according to the multi-laser principle and is equipped with not just one, but three scanner-guided, 500-watt fiber lasers. The three lasers are fitted with optics specially designed to enable them to operate simultaneously at any point in the system’s construction chamber. As a result, they can generate components much faster and more efficiently, irrespective of the number and geometry of the components.
Unlike other multi-laser concepts, it is not limited to defined areas in the process chamber. This makes the 3D printer particularly fast and productive. Another reason for the speed is the exposure strategies, which automatically calculate the ideal laser paths, so that all three lasers can always expose multiple parts. The finished components are literally seamless, as the outer contours are produced with a single laser. If all process parameters are in optimum settings, TruPrint 5000 requires just a third of the exposure time per job.
Based on Laser Metal Fusion (LMF) manufacturing technology, the system uses laser power to generate complex metallic components layer by layer in the powder bed. The components can measure up to 300 millimeters in diameter and 400 millimeters in height and consist of all weldable materials, such as steels, nickel-base alloys, titanium, aluminum and high-carbon hot-work steels. Pre-heating to up to 500 degrees Celsius ensures high component quality, particularly for hot-work steels and titanium, and guarantees a robust construction process for all materials.
