The joint type usually matters more than the adhesive brand
Makers often ask "what's the best glue for 3D prints" as if one product answers every joint. In practice, whether a joint should be glued at all depends more on the joint's geometry and how it is loaded than on which adhesive you reach for. A joint loaded in peel, where one side is pried away from the other like opening a can lid, defeats most adhesives regardless of brand, while the same adhesive can perform well on the same materials loaded in shear instead. This tool starts from the joint's mechanics and works toward a joining strategy, rather than starting from a product recommendation.
How the comparison works
A few conditions override everything else: if the joint must be disassembled, mechanical fastening wins regardless of load direction, since no common adhesive is meant to be reversible. If the load is primarily peel, mechanical fastening or a redesigned joint is favored, since peel is the weakest loading case for adhesives generally. Otherwise, the tool weighs appearance and load direction together, favoring an adhesive or solvent-welded bond (for same-material thermoplastic pairs) when appearance matters and the load allows it, and mechanical fastening when it does not.
Worked example
Two ABS/ASA parts joined at a flat lap, shear-loaded, no disassembly needed, appearance matters: the tool recommends solvent welding or a plastic-compatible adhesive as the best fit, since same-material thermoplastic pairs under shear load are a good candidate for a bonded, hardware-free joint, with mechanical fastening shown as the alternative if the bond does not hold up in testing.
Limitations
This tool compares joining strategies qualitatively; it does not calculate a bond or fastener strength for your specific load. Surface preparation, cleaning, roughening, or priming as appropriate for the material, is required for any adhesive option regardless of which one you choose, and a test coupon in your actual materials is the only reliable way to confirm a joint before committing the finished part.
