COEX - CoexFlex TPE 40D on X1C
I picked a a couple rolls of CoexFlex TPE 40D to print out some gaskets for a riser project and it came out beautifully on the X1C. Only area that a small amount of buildup was on the seam.
Not the cheapest filament but the quality is excellent and adhesion between layers is crazy strong. Tried to pull one of these printed pieces apart, bend it, twist it and no issues.
