Case Study Laser Metal Fusion (LMF), a manufacturing process where a laser builds up the component layer by layer in the powder bed. “This process is perfect for complex geometries. We need these to put these functions – that is, maximum cleaning performance with minimum water consumption – into practice,” explains Arikcan. TRUMPF experts streamlined the component’s design so it can be printed without any supporting structures, and with no finishing to be done afterwards. This printing process is software-driven, so the imperfections associated with manual gluing have been relegated to history. TRUMPF staff enlarged the nozzle attachment and added an outer channel guide to improve the component’s properties. This serves to furnish air to the system and creates a tighter throw pattern when the jet hits the surface to be cleaned. The preforms with the add-on component can be screwed into the bombs immediately upon printing. The substrate plate does not even have to be removed from the machine GHM edia B usiness to do this. “For the first time, this will allow 10,000 nozzle inserts to be manufactured per year,” notes Arikcan. Twofold increase in machine availability and improved component properties TRUMPF experts set up a test bed to examine and validate the 3D-printed components. “Measurements have shown that this shortens the job time for conventional steps by 53 percent,” says a clearly delighted Arikcan. The parts were made with the TruPrint 1000 3D printer; developed by TRUMPF, it features a single laser. This expert is confident that the time savings will be even greater with a multi- laser system. The new nozzles also deliver more persuasive performance with benefit of improved jet guidance. “We demonstrated that the water jet flows smoother than with the conventional design. We also expect the pressure on the surface to increase and water consumption to decrease,” says Arikcan. Another positive side effect is that this boosts turning and milling stations’ availability. TRUMPF not only manufactures the machines, systems, laser beam sources, and all optical components required for 3D printing; the company also has the necessary technology, process and digitalization skills. It is the only AM provider worldwide to have the full package, the entire skill-set under one roof. “We think in terms of form and function, which means we look at the product portfolio together with the customer and recommend 3D printing where it makes sense. Quality, cost reduction and time savings are our most important goals,” says Arikcan by way of explanation. www.trumpf.com 31 | january-february 2019 | Global MDA Journal Global MDA Journal
