Additive Manufacturing

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:

3D MetalldruckMetal AM by means of L-PBF

Laser Powder Bed Fusion (L-PBF) is a fusion-based additive manufacturing technology for metals. Thin layers of metal powder are locally melted by a laser and form a solid body upon cooling. Support structures might be required during printing, which have to be removed in a post-processing step. L-PBF is suitable for the production of prototypes. The following materials can be selected:

- 316L (1.4404)

- Hot-working steel 1.2709

- AlSi10Mg

- TiAl6V4

- Titanium Grade 2

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 3D Druck

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. Small series up to 500 parts are feasible. Currently, the following materials are available:

-  316L (1.4404)

- Cobalt-Chromium alloy (Stellite)

- TiAl6V4

 

 

  

 

Moldjet 3D Druck

 

 

MoldJet

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. Beside prototypes also small series up to 5.000 parts can be realized with this method. Currently, the following materials are available:

- Stainless steel (316L, 17-4PH, 15-5PH)

- Tool steel (M2, D2, H13, 4340)

- Inconel 718

- TiAl6V4

 

3D Druck MIM3D printed
plastic tool inserts

Here a tool insert made of a heat resistant polymer is produced by means of established AM technologies for plastics. Afterwards the printed tool insert is fitted into a metallic master form and prototypes can be moulded on conventional injection molding machines. Prototypes and small series up to 200 parts are possible with this method. The whole material portfolio of MIMplus Technologies can be processed.

3D Druck MetallpulverspritzgussMould tool
made of aluminum

A mould tool made of aluminum is much more cost efficient compared to a conventional steel tooling. First samples can be delivered within a few weeks. Small series up to 1.000 parts can be produced using an aluminum mould tool. The same materials as for the classical MIM can be processed with this method.
