Of all the plastics that can be 3d printed, are there any that are particularly well suited to being glued?
ABS and PC can be solvent welded and glued with all common types of glue. PLA works with superglue. Nylon needs special solvent-based adhesives.
ABS responds very well to CyanoAcrlyate, or CA glue, which is often sold as superglue or krazy glue.
What about epoxy?
@Andre_Roy there are huge differences in the qualities of epoxy. It’s definitely not going to work for PA and i’ve heard that PLA and PET are somewhat fussy with epoxy as well. ABS/PC should work, though.
epoxy is a generic term, which could apply to any number of two part or single part compounds. which epoxy do you want to know about? If it says it works on plastic, then it will probably work with ABS. I don’t print PLA, so I can’t speak to that subject.
I’ve been told methylene chloride and acrylic glue has a similar effect on PLA as acetone on ABS.
I’ve put a lot of thought into improving the bonds of split parts using more readily available and safer glues. I’ve found most glues have a lot of shear strength, but easily fail under tension (peeling). So I came up with a mechanical solution which I’ll test in my up coming prints.
@Chapman_Baetzel I didn’t know there were different epoxy types. I’ve only tried some 20 min epoxy I got from the hobby store, I expect my other hobby store epoxies would produce the same result.
@Thomas_Sanladerer You are probably right regarding epoxy and PLA.
I’m founder of a new form of technological review, that is the review of Technology with responsibility of assimilation into the human life in mind.We are a non profit organization centered on public advocacy with the purpose of new policy development.http://www.ResponsibleAssimilation.org is in its infancy ,meaning right now is the best time for reviewers to jump on board this inevitably historical movement . One of the things you might help with if interested is, helping us in advocating for a “drone operators license” of some kind. Such things are better dictated by the users during development, responsibly. Rather than the public demand the government do it in a blinding state of hindsighted haste after lives are lost . I firmly believe that if the users and developers of the unmanned vehicle community come together they could self-govern what is rapidly becoming a potentially dangerous air traffic environment for passenger commuting flight . You MUST do this yourselves, responsibly before tragedy not after! Im interested in your thoughts. best regards, Jason Eyer
