ExOne 3D printing will save MiMtechnik 13 weeks in solution enhancement time, tens of hundreds in prices


Metal injection molding (MIM) provider MiMtechnik, headquartered in Schmalkalden, Germany, has picked the ExOne Innovent+™ 3D printer to slice merchandise advancement lead periods. Used to the output of custom made fasteners, delivery time was decreased to a one 7 days, with eradicated tooling costs.

As a outcome, MiMtechnik was equipped to close a buyer purchase of 600,000 items for every year, with designs to improve creation to more than 1 million in the long term.

“This collaboration with MiMtechnik represents however an additional avenue for us to produce the gains of our metallic binder jetting to the marketplace,” said Jared Helfrich, ExOne’s Main Commercial Officer. “This is a further compelling ExOne story exactly where our purchaser, MiMtechnik, can present their consumers a brief, modern and value-powerful production process to differentiate on their own in the marketplace and gain new organization.”

ExOne Innovent+™  technical technical specs

The Innovent+ is a 3D printer specifically developed by ExOne for use in development and short-run productions. The machine works by using the company’s proprietary binder jetting technological innovation, with precision powder dispensing and a new state-of-the-art recoating system. It has a develop volume of 160 x 65 x 65 mm (6.3 x 2.5 x 2.5 in.). Minimum amount achievable layer thickness on the device is 30 μm, and print resolution is 800 x 800 dpi. As with all ExOne 3D printers, the Innovent+ is capable of generating pieces directly from 3D CAD information, producing the know-how simpler to combine with traditional engineering workflows. The device is also capable of 3D printing certification quite a few conventional powder injection molding (PIM) feedstocks, like a variety of stainless metal, tool metal, ceramics and tungsten alloys, a element that was of certain benefit to MiMtechnik.

Product development in times fairly than weeks

MiMtechnik’s constructing components fasteners are serially made utilizing MIM. On the other hand, ahead of achieving this stage, item enhancement and small-run productions are necessary to meet the specific wants of its shoppers.

At the starting of this process the purchaser requests a sample primarily based on a unique style. Then, with MIM, a prototype would be delivered to the buyer inside 10 to 14 weeks, at a tooling charge of concerning €10,000 and €20,000. By way of migrating this process to additive production certification, MiMtechnik has as an alternative been capable to produce fastener samples to clients within 1 week of inquiry, generating on common 100 pieces in 10 hours (excluding subsequent sintering). And, as the course of action does not need the generation of tooling, this price tag was eradicated.

Crucially, Innovent+ 3D printed sample fasteners also matched the mechanical and area end properties of the conclusion-use MIM areas as they were built working with the similar high density 316L alloy. Not only did this deliver a like for like comparison to the client, it meant that MiMtechnik could use its individual sintering techniques to put up procedure the parts.

As a outcome of ExOne’s additive production certification experience in the shipping of these samples, MiMtechnik was equipped to near an once-a-year get for 600,000 fasteners, which is to be improved to 1.2 million in subsequent a long time.

With regard to future 3D printing certification applications at MiMtechnik, Dr. Andreas Baumann, Specialized Leader at MiMtechnik, replied, “Definitely indeed. Just before starting off a MIM venture we offer you our shoppers to exam MIM like prototypes produced by this impressive shaping technology.”

“Customers can gain from the shortest guide time devoid of tooling expenses by possessing similar materials houses in sintered elements.”
