3D New Metal-AM Technology
Trumpf Delivers Part Complexity and Processing Speed
As noted previously, themes emerging from formnext include external part and powder management, 500 C build-plate pre- heating, three 500-W fiber lasers that allow scanning of the entire
build area, and other functions to drive productivity gains. These and other advancements were evident at the Trumpf booth, which showcased the new TruPrint 5000 semiautomatic laser metal fusion machine. Officials explained that the machine excels in producing complex parts as large as 300-mm dia. and 400-mm tall, from any weldable alloy.
Of note is the machine design that enables quick exchange of build and supply cylinders so that setup and production can occur in parallel, optimizing machine availability. In addition, the external part and powder-management system includes a sieving station, unpacking station and powder silo, again to allow this work to occur parallel to production while also ensuring operator safety.

Four 700-W Lasers Occupy SLM’s Large-Format Machine
Back on the big-bed train, we spied the new SLM 800 laser powder-bed machine that features as many as four 700-W lasers along with new permanent-filter technology, melt-pool moni- toring and laser-power monitoring, as well as improved machine- control software and an optional powder feeder that employs
vacuum technology. As with other large-bed solutions, the machine design facilitates integration alongside a fully automated handling—unpacking, preheating, cool down, powder removal and powder transfer all can occur without operator intervention. After presenting the machine to the crowd at formnext, SLM announced receipt of a major order for 20 units. www.slm-solutions.com
Higher Build Rates from Renishaw’s Multilaser System
The new RenAM 500Q from Renishaw is a multilaser AM system that features four high-power 500-W lasers, each able to access the whole powder-bed surface simultane- ously. The machine, therefore, according to company officials, achieves significantly higher build rates, vastly improving productivity and lowering cost per part. The RenAM 500Q features automated powder- and waste-handling systems that enable consistent process quality, reduce operator-intervention time and ensure high standards of system safety. Among its capabilities:
• Deposition rates to 150 cm3/hr.
• Intelligent gas flow that ensures the efficient removal of process emissions and optimizes filter life
• A single additively manufactured galvo mounting with internal conformal cooling- fluid channels that optimizes optical-system thermal stability
• Build volume: 250 by 250 by 350 mm.
