Use lighter, thinner materials
Use lighter, thinner and possibly fewer and less expensive materials without worrying about distortion, splitting, or crazing at the mechanically fastened site. Adhesive tapes use less space than traditional fixing methods, so your desired product weight, mass or size can be more easily achieved.
New design freedom and options
Improve appearance
Bond dissimilar materials
Cheaper prototyping in the early stages of design
Compare fixing and joining methods
Creativity + efficiency
