Germany-based 3D printer maker One Click Metal has launched its latest laser powder bed fusion 3D printer.
The new MPRINT + is based on the previously published MPRINT and is a barrier-free metal system developed for industrial prototypes and low-volume series applications. Primarily aimed at SMBs and educational institutions, it comes with a new 200W fiber laser and galvo scanner that are reported to offer higher productivity and precision over its predecessor.
Stefan Weber, CTO and co-founder of One Click Metal, explains: “When introducing the fiber laser in our metal 3D printer, it was important to us to retain the great advantages of the MPRINT and at the same time to improve the existing modules of the new MPRINT +. “

Metal 3D printing with One Click Metal
One Click Metal was founded in 2019 with the aim of bringing industrial metal 3D printing to the world. In addition to the MPRINT and MPRINT + 3D printers, the company produces its own automated powder handling station, the MPURE, for use with its additive manufacturing systems.
MPURE is a must-have unpacking chamber for powder removal and recycling with an ultrasonic sieve. With a frame of 1.1 x 1.9 x 0.79 m, the MPURE is designed in such a way that it sits right next to the MPRINT + in the workshop and gives users easy access to a holistic end-to-end workflow technical effort made possible. The device also has a connection to an external vacuum cleaner, which ensures a clean working environment without loose powder.

The new MPRINT + 3D printer
The new MPRINT + 3D printer has a cubic construction volume of 150 x 150 x 150 mm with an inert nitrogen gas outlet. As such, it is compatible with a number of reactive metals such as aluminum, stainless steel, and tool steel, all of which are provided by One Click Metal.
The device also offers an impressive focus diameter of 45 microns and a scan speed of up to 3000 mm / s.The company claims it could reduce the cost per component by up to 40% compared to competitors.
Much of the system’s accessibility relies on its easy-to-use supply cartridge system in which powdered feedstock is housed, recovered and transferred in modular containers. The MPRINT + has four cartridge slots, each of which can hold up to 11 kg of material. This means an oversupply of 250% in relation to the construction volume, which leads to fewer material changes and less downtime. Each of the cartridges is also equipped with a unique NFC label, which allows users to check the level on the fly while ensuring that incompatible metals are not accidentally mixed.
The cartridges integrate with the company’s MPURE unpacking station to automate much of the powder handling workflow. MPURE automatically depowers the part, checks the remaining powder for recyclability and uses an ultrasonic sieve to put unused powder back into a reusable cartridge – without the user having to come into contact with loose powder.
