2 Materials in one print (conductive Filament)

Recommended Posts

Posted · 2 Materials in one print (conductive Filament)

Hello,

has someone experience with the print of different materials in one sample. Is this feasable with only one Extruder (Ultimaker 2)? Can I change the material during the process? The idea behind it would be to use conductive Filament (functionalize.com) mixed with normal, isolating Filament to produce 3D prints for electronic use.

Does somebody have experience with something like this and is it theoretically possible with the ultimaker 2.

Yes, it is possible to do it. You can use the pause at Z option for this (and manually change the material). I also know of a company that is working on doing this autmoatically (mosaic), but only for 1.75 mm fillament atm.

It's also possible to use different gcodes. Assuming A=non conductive, B=conductive:

1. First you print an object with A. The print finishes

2. Switch material A->B

3. Then you print an object with B. You have to make sure that the position of the print is exactly on top of the previous print, and that the print head moves in such a way that it does not hit the previous print. Basically insert gcode so that the head moves above your previous print volume, and then moves towards the print area. Print finishes.

4. Switch material B->A

5. Similar to step 3, make sure your layers are exactly on top of the previous print and that your print head moves in such a way that it does not hit previous layers.

This is workable even if the conductive material is not all in one layer, but it will be very laborious.
