16 MoldMaking Technology July 2015 Additive Manufacturing 5-Axis Machining Center Adds AM Technology Hermle has integrated additive manufacturing capability into its C 40 U five-axis machining center. The new MPA 40 machine incorpo- rates the company's metal powder application (MPA) technology, a thermal spray process based on lower-energy kinetic compacting, or micro-forging. The hybrid machine has a powder application nozzle mounted alongside the vertical milling spindle and a heater built into the fourth/fifth-axis rotary swiveling table. A production cycle involves clamping an application-specific face- plate onto the rotary table, importing the CAD model of the component to be produced, and converting the 3D data into successive micro-forg- ing and milling cycles, which can be followed by water quenching and heat treatment, if necessary. Finished components can be as large as 550 mm in diameter and 460 mm deep, and weigh as much as 600 kg. Hermle Machine Co. / 414-421-9770 / hermlemachine.com Hybrid Machine Combines Powder Spray with Milling/Turning DMG MORI's Lasertec 65 hybrid manufacturing machine combines additive and subtractive processes to produce a complete part from powder. Unlike additive machines that use powder bed technology, the Lasertec 65 uses a powder spray technique that deposits material at 10x to 40x rates. It then uses conventional milling/turning processes to remove material from unwanted areas. The combina- tion of these two processes on a single platform and the ability to execute them sequentially provides design engineers with increased freedom and flexibility. DMG MORI / 847-593-5400 / dmgmori-usa.com Large-Format System Prints Parts Faster 3D Systems' ProX 950 stereolithography printer is equipped with its PolyRay print head technology, designed to manufacture parts as much as 10 times faster than other 3D printers. Those parts can range in size from extremely small to large without compromising feature details or true-to-CAD accuracy, the company says. The large-format, "fab-grade" printer also is said to offer high total material usage for reduced part cost over competitive alternatives. 3D Systems / 888-337-9786/ 3dsystems.com Laser Sintering System Builds Metal Parts EOS's M 290 direct metal laser sintering (DMLS) system, the successor to its EOSINT M 280, is designed for the production of serial components, spare parts and prototypes. In addition to a build volume of 250 x 250 x 325 mm (9.8" x 9.8" x 12.8"), the M 290 offers monitoring functions for both the system itself and for the build process. Equipped with a 400-W laser, it can be operated under an inert (nitrogen) atmosphere or under argon, which enables processing of a variety of materials, including light alloys, stainless and tool-grade steels, and superalloys. EOSystem machine software enables intuitive and task-oriented operation of the system via a graphic user interface that was developed specially for production environments. In addition, an operator assistant guides the user through the program. EOSprint desktop software allows jobs to be prepared and computed directly at the workplace, separately from the build process. The job file can then be transferred through the network to the system, which can then build the part. EOS / 248-306-0143 / eos.info
