printing 2 materials with Cura

[aag 6]

What is the best workflow for printing two materials with Cura? I need to print a cover with ToughPLA, and a flexible gasket with Hytrel. In theory I could print these separately and assemble them with glue, but since I do not need the second extruder for support, I thought I could try using two AA-0.4 cores for the two materials.  I use Fusion360 for design. How would you do that? Print two model and align them? The black contour is the hytrel (which is white in reality, but the black symbolizes "rubber".

I'd personally go for glue-ing, because if you print both at once you do increase the chances of failure (so if one material fails, you lose all of your progress). Another factor is that it might be tricky to get the materials to stick together, so you would need to glue them anyway. On the other hand, it might stick really well together, maybe even better than it would by means of glueing.

 

As for printing both of them at once, you are correct. You need to export both models separately, load them in Cura, assign the right extuders and then merge the models.
