Double Sided Tape on 3D Printed Parts 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. Below you will find the results of this testing as well as clickable links to sources where this tape can be purchased.
