Primarily based in Wuerzburg, Germany, Headmade Supplies not solely provides patented sinter-based chilly steel fusion (CMF) expertise to its clients, but additionally encourages them to think about new methods to design and manufacture with 3D printing expertise—whereas nonetheless falling again on standard strategies as wanted. Its modern and low-cost printing processes for steel have earned the corporate the eye of customers searching for assist in design, half manufacturing, and course of integration, because the effectively because the current reward of €1.9 million in funding from the Industrial Applied sciences Fund of btov Companions.
The hefty sum shall be put towards “scaling up” its expertise, in accordance with a current press launch despatched to 3DPrint.com. The corporate can even be growing buyer and advertising companies additional. As a by-product of Würzburg-based polymer analysis institute SKZ, the Headmade Supplies crew has been engaged on its chilly steel fusion expertise for 5 years. Because it companions with btov, it’s anticipated that analysis and growth will progress extra quickly.
“We see the Chilly Steel Fusion expertise as a really viable strategy for serial manufacturing because of the excessive value effectivity of the method. The mixture of mechanical half properties identified from steel powder injection molding (MIM) course of and appreciable course of benefits, reminiscent of lowered security necessities on account of simpler powder dealing with and better inexperienced half stability, can also be vital right here,” says Robert Gallenberger, associate of the btov Industrial Applied sciences Fund.
Chilly steel fusion expertise started by the hands of founders Christian Fischer and Christian Staudigel in 2015 whereas each have been nonetheless employed at a analysis institute. Sharing an curiosity in machine constructing, their objective was to carry serial manufacturing to 3D printing—eliminating limitations, lack of affordability, and creating higher designs for a variety of functions.
The method is totally different from different 3D printing methods because it combines steel sintering with SLS printing (often reserved for manufacturing of 3D printing plastics). The secret is within the plastic binder blended into steel powder, permitting for extra versatile use; for instance, with chilly steel fusion, steel components could be printed on laser sintering techniques meant for plastics just like the EOS Formiga P110 or the Sintratec S2. The elements are then positioned in a debinder after which furnace for remaining sintering.
Headmade Supplies claims that different advantages of CMF embrace the flexibility to make use of a larger vary of “mature machine expertise,” requiring no construct plates or assist buildings. Customers can depend on financial savings in money and time, with elevated productiveness. Feedstock left un-used can simply be reused, and due to superior inexperienced half energy, each automated depowdering options and tough manufacturing environments are acceptable. Maybe extra importantly, as a result of the method could be carried out utilizing present SLS machines, house owners of these techniques can start making steel components with out investing in new steel 3D printers, even the brand new era of certain steel printing processes, like these from Desktop Steel.
“In terms of the economical collection manufacturing of complicated steel components, there isn’t a means round 3D printing with the chilly steel fusion expertise,” says the Headmade Supplies crew of their white paper, “Chilly Steel Fusion / Steel SLS Expertise.”
The Headmade Supplies crew plans to 3D print collection with as much as 100,000 components per yr. At the moment, it provides its sinter-based 3D printing processes to clients, utilizing optimized feedstocks and companies whether or not in serving to with design and manufacturing, in-house manufacturing, or ready-to-use remaining components.
Total, 3D printing with steel continues to extend in reputation for industrial customers, from making the most of micro-gravity and 3D printing in area with the potential for big buildings, to experimenting with new supplies, and even furthering electronics with liquid alloys.
