Protolabs Launches 3D Printed Cobalt Chrome
Edited by AM Staff
The UK’s fastest digital manufacturer has launched 3D printed cobalt chrome - a new material from Protolabs - resistant to heat, wear and corrosion for use across multiple sectors.
Protolabs has launched 3D printed cobalt chrome, a new material resistant to heat, wear and corrosion for use across multiple sectors. The super alloy could enable the oil and gas industry to design and develop cobalt chrome parts not previously possible, with the aerospace sector also expected to benefit due to cobalt chrome’s high strength to weight ratio.
Hard-wearing cobalt chrome is well known for its excellent corrosion and creep resistance. It can withstand temperatures of up to 600oC and its low nickel content gives it excellent biocompatibility making it ideal for orthopaedic and dental applications.
The 3D printing process used by Protolabs, direct metal laser sintering (DMLS), can produce very fine resolution parts down to a minimum feature size of 1.00mm with a minimum wall thickness also of 1.00mm.
DMLS uses a computer-controlled, high power laser beam to melt and fuse layers of the metallic powder together. The company can produce parts using the process in as little as a day, which they claim makes them the fastest digital manufacturing company in the world.

Andrea Landoni, 3D printing product manager for Protolabs, says: “Cobalt chrome is one of the toughest materials known and can be polished to an extremely smooth surface. ” Landoni adds: “One of the problems of cobalt chrome is that it is so hard wearing that it is very difficult to produce parts from it using other processes such as CNC machining. The properties of parts produced by DMLS are also equal to or better than those of wrought materials and the process is ideal when the geometry or structure of a part is simply not possible using any other process.
The largest high-pressure die cast tool builder in North America is 3D printing die inserts and water jackets for major automakers. It’s a tough sell, but one company is succeeding — and it’s just getting started.
Origin’s platform isn’t just another resin 3D printer based on digital light processing (DLP). Through hardware, software and material partnerships, the company is changing what is possible inside a photopolymerization printer.
New potential for mold tooling applications is reached with custom-designed materials for additive manufacturing.
