I had epoxied up a sheet of the old pink foam, that had problems with part removal. I wanted to make some pegs for the workmate, that I use for support removal, so the test was run making two pegs:
I used Insight (sparse model, and sparse support). P400 model material, and release support.
I started the run 0.005″ above the coated foam (I think — the Z-Axis DRO has been acting up). The first layers of support went down pretty nicely:
Things continued well:
Support for the barbs looked okay while running:
The finished tray of parts:
The parts were easily (almost too easily!) from the foam:
The foam was intact and not damaged at all:
The bottom layer of support was pretty irregular like I was too far away from the foam when I started the run:
Once I got the parts to the support removal bench, it was obivous the bottom was bowed quite a bit:
Also, the Y+ edge of the back part was completely unattached at the entry corner:
Using a mini-torch, I heated up the unattached edge, and stuck it down. It shrank a little bit being such a big area:
A good time to try the epoxy part finishing, so I mixed up a small batch and brushed on with an acid brush:
I’ll run these again of the same foam, but this time right at touch-off.
