Abstract

1. ABSTRACT The idea would enable to install a 3d printer into a space station which is able to produce 3d printed parts in space. This could be spare parts or parts for new objects. Powder Bed 3d printing is considered as working only using gravitation to keep the applied powder in the position in the build chamber. Only wire feed 3d printing is considered as working I space due to the fact that the deposed material is glued or welded together. No gravitation would be needed for the wire feed 3d printing. Nevertheless today's powder bed ALM process is showing very good results with metals, and is strongly requested for application in space. This is a new and unique capability, as it would enable to produce 3d printed parts with high performance directly in space and it would overcome the issue that today's 3d printer with powder bed technology (see Fig. 1) do not work without gravitation.

1. ABSTRACT

The idea would enable to install a 3d printer into a space station which is able to produce 3d printed parts in space. This could be spare parts or parts for new objects.

Powder Bed 3d printing is considered as working only using gravitation to keep the applied powder in the position in the build chamber. Only wire feed 3d printing is considered as working I space due to the fact that the deposed material is glued or welded together. No gravitation would be needed for the wire feed 3d printing. Nevertheless today's powder bed ALM process is showing very good results with metals, and is strongly requested for application in space.

This is a new and unique capability, as it would enable to produce 3d printed parts with high performance directly in space and it would overcome the issue that today's 3d printer with powder bed technology (see Fig. 1) do not work without gravitation.


2. DISCLOSURE

The space ALM printer is based on the principle of applied artificial gravity. The Space ALM printer is consisting out of many 3d printing chambers (see Fig. 2 and 3). Each of these 3d printing chambers contains a working 3d printer. The laser or electron beam process could be applied on the ALM Powder bed process.

Other processes which could also be applied are Stereolithografie, Digital Light Processing (DLP), Inkjet Binder Jetting

All these 3d printing chambers are located inside a centrifugal device as shown Fig. 2 to Fig. 4. If the 3d printing chambers are b...
