A Milestone in additive manufacturing: The world's largest amorphous-metal component at Automate 2019

HANAU, Germany, April 8, 2019- Heraeus Additive Manufacturing, a leading developer of special metals and the corresponding 3D printing processes, announced it would present a world record additive manufactured gear wheel made of amorphous metals at Automate 2019 in Chicago.


The gear wheel, the world's largest amorphous-metal component, was printed in a standard SLM system with material from Heraeus. With this new milestone, Heraeus is breaking through the boundaries of 3D printing and opening completely new design possibilities for a wide range of industries - from automation solutions and robotics to aviation, medical technology and the automotive industry.

The gear wheel printed by Heraeus eclipses all previous results. Produced by additive manufacturing, this compact machine part weighs two kilograms. Due to the required high cooling rates of mainly over 1000 Kelvin/second, only small parts could be produced from amorphous metals previously. Because the topology of the gear was also optimized during development, material and process experts were able to reduce the weight by 50 percent compared to conventional manufactured versions.

Heraeus has now redefined the existing limits of technology in terms of size and complexity, revolutionizing design possibilities, for example, in the automation industry as well as in robotics. Heraeus set this world record using a commercially available laser melt printer.

Amorphous metals allow completely new design possibilities and applications

In contrast to pure metals and classic alloys, amorphous metals are characterized by an irregular, non-crystalline structure. They combine properties within one material that normally are not feasible: extreme hardness and high yield strength with a high elasticity. Amorphous metals are characterized by good corrosion resistance, excellent wear resistance and the elasticity of polymers. They also have soft magnetic properties and are easy to magnetize and demagnetize. With this combination of properties, amorphous metals are superior to steel, titanium and many other materials.

Reduced weight thanks to precision manufacturing

High-precision layer-by-layer production with special materials from Heraeus also reduces material usage, saving weight and costs. Using 3D printing also reduces overall production costs. With conventional methods, making complex parts require numerous process and manufacturing steps. Several individual pieces have to be produced and then assembled into a unit. However, 3D printers accomplish this in a single process. Following assembly in the printer, moving parts are immediately ready for use and fully functional.

The world's largest printed amorphous-metal cog wheel can be seen live at the Heraeus booth at Automate in Chicago: April 8-11, 2019, McCormick Place, Booth 9619.

T.J. Davies' Retention Knobs

T.J. Davies' Retention Knobs

Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
