My first successful print with TPE filament, for school project.
First ten photos are final, others are fails.
TPE is pretty different from PLA in many ways when printing, it requires some experience with it.
If you miss some of them, you'll get things like these failed photos.(like me!)
These are several things that I've missed when printing with TPE.
First, extruding speed.
TPE is much softer than PLA. If you attempt the speed of PLA for TPE, suddenly the filament starts to bend inside the extruder.(it does work well for few minutes tho)
Eventually it will start extrude to other side, making beautiful spaghetti. (plus black substace on extruder if you lucky)
As a solution, I printed filament guide and adjusted printing speed. They works really well.
Second, support angle.
Not only the support Z gap, support's angle is really important.
If the angle is small enough, the main body's surface starts to act like a part of support. (as opposed to PLA)
If you try to remove it, you get peeled surface like that photo.
I solved this problem by rotating the model like that, got inspiration from ice cream cone.
After these fails, I finally got the result. (still I had to remove the support and strings for 1 hour)
Material : TPE
Print temp : 210 Celsius
Bed temp : 90 Celsius
Print speed : 30mm/s
Retraction : No
Fan speed : 50% (it cools down the bed)
Support Z gap : 0.3mm
