Support test
In the test model of insulin below you can see adhesion issues of the black ABS on the green PLA support material towards the bottom of the model.
PLA support under ABS is worse than PLA under PLA. The above model prints well with the latter. Adhesion between ABS and PLA is apparently too low for thin support structures. Even on the raft (the platform in green) ABS does not stick well. It is better though than HIPS and ABS.
