The following example of an application is concerned with printed parts from our beri-boy filament printer. We were able to replace traditionally manufactured machine components by 3D-printed parts:
Original version of the BERI.CO.CLEAN
Partially printed version of the BERI.CO.CLEAN
Housing with integrated functional elements
Support element 1 photocell
Support element 2 photocell
A FDM/FFF 3D printer, like the new beri-boy, operates based on the so-called Fused Deposition Modeling procedure. This means that a thermoplastic material (in the form of a filament or pellets) is liquefied in a hotend and applied as a thin thread in layers of a defined diameter.
Several of these resulting layers then make up the 3D-printed part.
All FDM/FFF printers employ thermoplastics, i.e. plastics that liquefy under heat. They may contain additives, in order to obtain specific properties. Nevertheless, the method is, in principle, used to print plastic parts. 3D-printed metal parts are produced using other methods of additive manufacturing.
The replacement of functional parts of mechanical engineering by 3D-printed parts may be self-evident, but it must always be critically reviewed and evaluated.
One can assume that injection-molded parts can be most easily replaced by printed workpieces, since the available filament plastics can nowadays match the qualitative properties of injection-molded parts.
At the FEINTECHNIK R.Rittmeyer GmbH we are constantly scouring all our machines for suitable functional parts that can be replaced by 3D-printed components. For this, we initially check all the parts that are not exposed to particularly large static or dynamic loads and for which appearance is not of primary concern.
