lchi 3D pRiNTER
The NPPower Malachite is an affordable, small, and highly efficient table-top 3D printer for metal, making it ideal for small enterprises, educational institutions, designers, laboratories, and can also prove to be invaluable to large scale operations with its printing flexibility and downtime minimisation.
By applying the LPBF (Laser Powder Bed Fusion) method, a 200 W fiber laser, and galvo scanner, the 3D printer allows for swift and efficient creation of complex and unique objects that result in thin walled as well as intricate lightweight designs. With its extraordinary printing flexibility, it is suitable for all non-reactive metals such as Cobalt-Chrome, stainless steel, Bronze, Brass, Nickel, etc., furthermore offering a layer thickness ranging from 15 to 85 µm. The entire process is additionally accelerated by a double-piston powder loading system combined with an intuitive interface, making the operating of the Malachite simple and straightforward.

The Malachite 3D printer produces solid metal objects by applying the LPBF – Laser Powder Bed Fusion method, where a coating mechanism distributes very thin layers of metal powder onto a build plate, which is lowered layer by layer along the Z axis. Each layer of the metal poweder is then in turn melted in the required position for the object by selectively melting the metal powder with the help of a high-power laser beam and galvo scanner, directing the laser beam.

Mechanical
3D printed components are built layer by layer, making it possible to design light-weight thin-walled freeform geometries, hidden channels or voids, challenging internal passages and features that could not be achieved using conventional manufacturing techniques such as casting or machining.
Prototyping
LPBF shows clear advantages for rapid prototyping, as it decreases lead-time and parts can be built in a matter of hours, as well as production manufacturing by saving on material and significantly reducing costs by building parts additively to form near net-shape components rather than by removing waste material. The result is fully dense durable metal parts that can be used as functional prototypes as well as end-use production parts.
Design
By enabling complex geometries, unique and intricate designs, as well as being able to process a wide range of alloys, 3D printing of metal has presented itself as a fantastic new way of creating stunning jewellery and accessories. Allowing easy modification and exact repetition it increases accuracy as well as poses no limit to creativity.
