Chinese manufacturer of industrial 3D printers Eplus3D has released the newest member in its production portfolio: the EP-M450H machine. With a build chamber of 455*455*1100 mm³, the new machine is described as the tallest in Eplus3D’s portfolio.
Like its sister machines, the EP-M450H is based on laser powder bed fusion. It enables the production of premium quality metal parts without requiring any tools. With this new solution, the machine manufacturer ambitions to provide tailored metal additive manufacturing solution to large scale parts to customers across the world – customers that operate in the aerospace, aviation, automotive and defense industries.
As far as materials are concerned, the new machine can process a wide range of metal powders including Titanium Alloy, Aluminium Alloy, Nickel Alloy, Maraging Steel, Stainless Steel, Cobalt Chrome, Copper Alloy, etc.
The machine features a dual laser system with two 500 W fibre lasers. Due to a deviation of less than ≤±0.1 mm between the g-fibre lasers, the machine delivers parts whose mechanical properties can be compared to parts built with a single laser machine. The build rate for the machine is up to 55 cm3/h, with density up to 99.9% and <5% deviation in mechanical properties.
Furthermore, operators will experience a reduced gas consumption during build time, ≤6 litres/min, which means they can lower operation cost, while the blow back enabled filtration system is intended to remain active for over 1,000 hours.
As for software, it should be noted that the machine’s software supports SLC and CLI formats. It can be integrated with Siemens NX software to realize effective planning of design, simulation and printing path planning.
To highlight the capabilities of this machine, Eplus3D manufactured several parts that can be used for various industries:
One of them is a full-size nozzle for the aerospace industry which required the use of IN718 Nickel-based Superalloy as material. The part measures 230x401x554mm³ and took 152h for manufacturing.
