Flemish startup Valcun has launched its 3D metal printer for aluminium, dubbed “Minerva”, and will start the pre-sale process at Rapid-TCT in Chicago in May.
The printer uses molten metal deposition technology, which is similar to fused filament manufacturing, but with aluminum as the raw material. The process enables 3D printing with an overhang of up to 70 degrees without the need for a support structure.
Valcun has also received approval from the European Space Agency to demonstrate Minerva’s ability to print aluminum parts in the vacuum of space.
“Since there is no oxygen, oxidation could not occur. Also, gravity works against the process,” said Jonas Galle, founder and CEO of Valcun.
“Microgravity like in space would then just be an advantage. Now we have to show that we achieve the same quality, regardless of the position of the 3D printer.”
The first version of Minerva will be a fully open system, with the next generation planned for a wider market release. The company is currently looking for users to help optimize the machine. Valcun aims to serve manufacturing companies that seek economic value through the combination of AM and aluminum, such as semi-finished products, heat exchangers and other complex parts.
The company is also studying 3D printing with aluminum chips and is developing a print head attached to a robotic arm for larger parts. Valcun is one of the few companies using this technology, with only Xerox and Grob as potential competitors.
