DMG MORI, one of the leading machine tool manufacturers, has launched a new hybrid additive manufacturing system, named LASERTEC 125 3D hybrid.
Introduced to 2019 Forms, the LASERTEC 125 is a 5-axis laser deposition welding (LDW) system designed for the maintenance, repair and production of considerably larger parts, including parts up to ø 1250 x 745 mm and 2000 kg.
Additive manufacturing at DMG MORI
Founded in 1948, DMG MORI has grown into one of the world’s largest machine tool manufacturers, with more than 160,000 installations worldwide. Based in Japan, DMG MORI also has a sister company located in Germany and facilities in the United States, Europe and Russia. The company’s main product offering includes lathes, machining centers, milling machines and CNC controls.
DMG MORI is also developing a range of metal additive manufacturing systems, divided into two categories: nozzle and powder bed 3D printers. Its powder bed systems, under the LASERTEC SLM brand, include the LASERTEC 12 and the LASERTEC 30 3D printers. In its LASERTEC 3D line based on powder nozzles, DMG MORI has developed the LASERTEC 65, and two hybrid systems combining the manufacture of powder nozzle and lathe-mill machining in one work area. These are known as LASERTEC 65 3D hybrid and the larger LASERTEC 4300 3D hybrid.
During the IMTS 2018 edition, 3D Printing Industry spoke with DMG Mori President Dr Masahiko Mori, who stated his belief that the 2020s will be the decade of additive manufacturing. With this in mind, DMG Mori “spends thousands of millions of euros for this [AM] type of technology, ”he said.
In November of the same year, the company then announced its intention to expand its global presence in metal additive manufacturing by acquiring a 30% stake in INTECH, an Indian developer of 3D printing software. Additive manufacturing was also listed as a leading solution in the company’s collaboration with Porsche, where DMG MORI acted as exclusive partner of the Porsche FIA World Endurance Championship team.
The LASERTEC 125 3D hybrid
Further expanding its hybrid LASERTEC 3D series, the new LASERTEC 125 system from DMG MORI uses LDW technology, a form of direct energy deposition (DED) 3D printing, which deposits metal through a powder nozzle. As it shapes the 3D part through the LDW process, the system automatically switches to 5-axis simultaneous milling in one setup. By machining the 3D printed part as it is produced, DMG MORI claims that the LASERTEC 125 3D hybrid can reduce processing times by up to 80%. Users can skip post-processing steps like heat treatment because the system can deposit materials with a hardness of up to 63 HRC.
The hybrid capabilities of the system also allow the production of new part geometries and lightweight structures, reducing the weight of parts such as turbine blades by up to 90%.
DMG MORI also specifies that the machine is particularly effective for the repair of parts, a often used app for DED-based 3D printing by people like Optomec with his Laser-designed mesh shaping technology (LENS). With the LASERTEC 125 3D hybrid, the damaged area of a part is first prepared by milling, before the repair is carried out using LDW, and then finished with a final milling process. This can help reduce maintenance times, making the machine suitable for industries such as oil and gas, as well as chemicals, pharmaceuticals, and energy.
The LASERTEC 125 3D hybrid is also equipped with DMG MORI’s AM Assistant software, which allows users to monitor manufacturing processes including weld pool size, temperature, nozzle-to-component clearance, and thermal monitoring. keep on going. Process parameters can also be observed and adjusted using software. AM Assistant will further display stored 3D process data from the production process for evaluation and generate reports for quality assurance.
