JULY 2018 Additive Manufacturing IMTS 2018 ON DISPLAY 46 Metal Production Module Promotes Safety During AM Process AddUp's pre-fabricated, turnkey FlexCare System is a contain- erized production system for metal additive manufacturing, built according to health, safety and environmental standards for working with metallic powders in the 3D printing process. The system houses the FormUp350 industrial metal 3D printer, including all inert, ancillary powder charging, evac- uation and recycling equipment required to safely operate the 3D printing process. An integrated washing machine cleans plates and parts as they exit the system. The system includes an HVAC system with airlock technology to control the atmosphere and exchange of air, and is designed to protect operators and avoid the risks associated with metal additive manufacturing. The system's modular units can be customized for space constraints and can be adapted to house several additive machines or other postprocessing equipment in a workshop. Module design, according to the company, offers a cost- effective alternative for housing, supporting and operating a metal printing process. AddUp | West, Level 3, Booth 432400 Five-Axis Hybrid Machine Applies Hot Wire AM Technique 3D Printers Suit High-Temperature Thermoplastics Applications Updates to the A2V4 and A4V4 3D printers, designed by 3ntr and distributed by Plural Additive Manufacturing, include print beds and build chambers that withstand temperatures as high as 160°C and 90°C, respectively, to support high-temperature thermoplastics applications. Their extruder systems feature 450°C extruder heads, im- proving temperature control, while the volume of the liquid coolant systems has been doubled. The printers also feature the Diamond Tray, a reusable carbon-fiber build plate with a temperature-sensitive, permanent adhesive layer that includes Ultem PEI. The tray holds models tightly at build chamber temperatures with- out clips, hairspray or tape, and enables quicker removal of models from the print bed. Plural Additive Manufacturing | West, Level 3, Booth 431603 Mazak Corp.'s VC-500A/5X AM HWD multitasking ma- chine is said to reduce lead times and part costs, increase machining accuracy and part quality, and improve produc- tivity. The machine incorporates hot wire laser deposition technology to combine additive processes and program- mable welding automation with five-axis machining. An arc torch melts metal wire directly onto a base ma- terial or part, even if the two materials are dissimilar. This enables shops to generate precise sealing coatings along with near-net-shape part features or repair components such as impellers, turbine blades, and tool and die parts. The machine's laser cladding head has the same five-axis capability as its milling spindle, providing maneuverability. The platform suits high-volume additive manufacturing and helps to minimize equipment and material costs. The head also incorporates an automatic wire feeder system that feeds welding wire to an argon gas nozzle. The head provides a deposition rate of 3 to 4 lbs/hr. and offers a 98 percent material utilization rate. The machine has a trunnion-style rotary/tilt table to pro- cess small parts. It also features a Mazatrol SmoothX CNC and MTConnect-compliant features to ease programming and decrease cycle time. The machine features a CAT-40, 12,000-rpm spindle facilitating the machining of all common metal materials including steel, aluminum and cast iron. Optional speeds of 15,000 and 20,000 rpm are available to address a variety of part production requirements. A 30-tool storage maga- zine contributes to uninterrupted part machining.
