lchi 3D pRiNTER

The NPPower Malachite is an affordable, small, and highly efficient table-top 3D printer for metal, making it ideal for dental and small enterprises, educational institutions, designers, laboratories, and can also prove to be invaluable to large scale operations with its printing flexibility and downtime minimisation.

Utilizing LPBF with a 200 W fiber laser and galvo scanner, this 3D printer swiftly creates complex, lightweight objects with thin walls. Its flexibility supports various metals (e.g., Cobalt-Chrome, stainless steel, etc.) with 15-85 µm layer thicknesses. Operation is streamlined by a double-piston powder feeding system and intuitive interface.

The Malachite 3D printer produces solid metal objects by applying the LPBFLaser Powder Bed Fusion method. This involves coating a build plate with thin metal powder layers, which are sequentially melted by a high-power laser and galvo scanner. The build plate lowers with each completed layer.

Dental

Given the unique characteristics of each tooth, 3D printing offers an ideal solution in dentistry by providing unparalleled precision in the fabrication of dental prosthetics. Its streamlined process, which minimizes manual steps and material waste, coupled with low maintenance costs, significantly contributes to reduced production expenses for crowns, bridges, and partial denture frameworks, ultimately leading to faster turnaround times and potentially lower costs for patients.

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.
