Malachite · LPBF metal 3D printer

Dense metal parts, printed in your own lab.

Malachite melts cobalt-chrome and stainless steel powder with a 300 W fibre laser. It is built for dental labs, workshops and universities that want in-house metal printing without an industrial budget.

Applications

One machine for crowns, brackets, prototypes and jewellery.



Dental

Print crowns, bridges and partial denture frameworks straight from the scan, with fewer manual steps and less wasted alloy.

Co-Cr · crowns, bridges, frameworks



Mechanical parts

Build thin-walled, lightweight parts with internal channels and voids that casting or machining cannot produce.

Stainless steel · freeform geometry



Prototyping

Go from CAD to a fully dense metal part in hours. Use it as a functional prototype or as the final production part.

Near-net-shape · minimal machining



Jewellery & design

Produce intricate pieces and exact repeats in a range of alloys, without the limits of lost-wax casting.

Fine detail · repeatable series

Printed on Malachite

Real parts, straight off the build plate.

How it works

Laser powder bed fusion, one layer at a time.

Spread a powder layer. The double-piston feeder coats the build plate with 15–85 µm of metal powder.
Melt the cross-section. A galvo scanner steers the 300 W laser across the powder, fusing it into solid metal.
Lower and repeat. The plate drops by one layer and the cycle repeats under argon or nitrogen.
Remove the finished part. The part is lifted out of the powder bed, cut from the plate and finished.

Why Malachite

Cut outsourcing time and cost without an industrial footprint.

Most metal printers are sized and priced for aerospace. Malachite gives smaller teams the same process at a scale they can run every day.

Shorter lead times. Print parts in-house the same day instead of waiting on an outside bureau.
Lower cost per part. Additive building uses only the material the part needs.
Very low gas use. Under 0.3 L/min of nitrogen while printing.
Less post-processing. Near-net-shape parts need little machining.
No subscriptions. You own the machine. No lock-in fees.
Your colours. The cabinet can be finished to match your company branding.
