For anyone looking to print using a flexible material, I have had really great results with this stuff:
GP3D Elastic 3D Printer Filament Natural Color
I used a custom material setting of 216 degrees and it works really well. I run the standard 0.4mm nozzle, "fine" print setting, 0.20mm layer thickness, NO RAFT. The raft only takes up time and material. The part peels off the platform with ease and no tool required. So happy with it.
I could not get the Trinus printer to even get one layer out with this material after numerous attempts. This printer is amazing.
