Double Sided Tape Strength Testing
Doubled sided adhesive tape can be used to attach 3D Printed parts to each other. We have done some testing with our preferred tape vendor (tesa tape) on which of their generally available tapes worked the best for both raw Nylon 12 (PA-12) parts as well as Nylon 12 parts that had been coated in Cerakote .
