Metal Additive Manufacturing company Meltio, based in Linares, Spain, and Las Vegas, Nevada, USA, has launched the new version of its Meltio Engine, a fabrication module which enables the Additive Manufacturing of full-density metal parts when integrated with CNC machines, robots, and gantry systems, in a primarily wire-based Directed Energy Deposition (DED) process said to optimise resources and save production costs.
According to Meltio, the revamped model is the result of several months of R&D development after the first public presentation of the company’s product portfolio at Formnext 2019. The new version is said to offer greater portability and more compact dimensions (94 x 75 x 45 cm), which allow easy integration with most existing CNC, robotic and gantry systems. The Meltio Engine also includes an onboard computer with integrated touchscreen and GUI for easy operation and monitoring of manufacturing jobs.
The Meltio Engine uses the same proprietary Meltio LMD-Wire + Powder technology used in its compact metal Additive Manufacturing machine, the Meltio M450. The build head uses a high-power multi-laser configuration to deposit layers of metal in wire format, with the added option to work with powder for the creation of special alloys.
Additionally, the Meltio Engine can manufacture full-density metal parts with materials such as stainless steel (all common grades), Inconel (718 and 625) and Ti6Al4V (grades 5 and 23). The company explains that many other materials are currently under development at Meltio’s R&D centres in the USA and Spain, such as copper, aluminium, molybdenum, tungsten, X9, gold and invar.
Ángel Llavero, Meltio’s CEO, stated, “After the launch of the M450, the Meltio Engine moves the Meltio LMD to a new format with which it will solve one of the great historical limitations that Additive Manufacturing had: the ability to manufacture large parts. Now the part size is limited only by the capacity of the robot, the gantry or the CNC in which the Meltio Engine is integrated.”
Llavero went on on highlight how the Meltio Engine is designed to manufacture at industrial mass-production levels, to optimise resources, and to allow small, medium and large companies to use the technology to additively manufacture metal parts in the most optimised way. “That was unthinkable until the arrival of Meltio because of costs, difficulty, need for space,” he continued. “Is Meltio Additive Manufacturing? Yes, but it offers a completely different metal Additive Manufacturing concept than the one conceived today by the world market.”
Brian Matthews, CTO of Meltio, commented, “Because it’s a one-step process the production time from conceiving a part to manufacturing the final design is very fast, typically just a few hours. This can compare to weeks or months in a conventional process. The production cost is also very low because the entire manufacturing process is performed in one machine.”
“Meltio has removed this barrier, unlocking the true potential of hybrid manufacturing for the first time,” Matthews concluded.
