Beside conventional metal injection moulded parts, MIMplus Technologies is also able to offer prototypes and small series production in a time and cost efficient way using innovative technologies. According to the requirements of the prototypes and the number of parts, we can choose between the following technologies:
Metal AM by means of sinter-based technologies
In case of sinter-based AM technologies a green part is printed. Through the subsequent process steps debinding and sintering the green part is transformed into a nearly dense (>96%) and fully metallic component.
Cold Metal Fusion
This method is performed on conventional SLS machines known from plastic 3D printing. After spreading a thin layer of a feedstock powder (metal powder + binder) in the build box, the binder is locally melted by a laser. No support structures are necessary during printing. The process is suitable for the production of prototypes as well as for the series production of several thousand pieces. Currently, the following materials are available:
– 316L (1.4404)
– Cobalt-Chromium alloy (Stellite)
A wax-like mould is printed layer by layer. After each layer a metal paste is placed in the mould. During printing the component is supported by the surrounding mould material, thus support structures are not required. The MoldJet process enables series production of small to medium quantities up to approx. 100,000 pieces. Currently, the following materials are available:
– Stainless steel (316L, 17-4PH, 15-5PH)
– Tool steel (M2, D2, H13, 4340)
– Inconel 718
