What do you guys use to glue together your parts?

Post by AverageVeganDude » Sun Jan 17, 2016 9:09 am

I generally print in ABS, PLA and HIPS. I was wondering if there is a specific glue that bonds the best?

Thanks.

For ABS, you can brush a tiny bit of acetone on the parts and press them together. As long as you're not expecting a super strong bond, I've found this works fairly well.

What about a tight secure bond?

You might check out the acrylic cement/solvent that will help clear out PLA from nozzles mentioned elsewhere in the forum. I forget the name for it.

Plastruct Plasti weld for ABS. http://www.plastruct.com/Pages/CementGuide.html sometimes spam with epoxy or CA glue depending on the application. I also use Squadron white or green modeling putty to fill in surface imperfections.

I've also used this stuff for PLA, it gives a pretty good bond as long as there aren't gaps between parts.

I like to glue ABS by making an ABS-based glue. I mix scraps of ABS with acetone in an eye dropper and leave overnight. It makes a gummy liquid that welds ABS together. I build robots that need to be strong. Never had a failure.

I use friction welding. Short piece of filament in a dremel, boom.

Dissolve bits of ABS filament into a bottle of Acetone to make ABS glue. The stuff is really strong. You can't just use straight acetone on the part and expect them to stick well from my experiences.

If you need filler material for ABS, add more chunks to the acetone to make a thicker paste.

You can't get much stronger than chemically welding the two parts together. :)

Acetone solution of ABS is good for ABS. I have had trouble with PLA. Recently I tried Locktite super glue on a PLA piece. That works far, far better in my experience than other cyanoacrylates, and has a very short clamping time (~30 sec.)

I used to like to do wood working, and from that I learned that the better the joint you can make, the easier it is to glue. The famous woodworker, Klaus Schulz, used Elmer's white glue on $10-12K hand made coffee tables for two reasons. His joints were superb (dovetails 0.002 by hand), and the white glue was water soluble for when the table had to be take apart for refinishing in a 100 years or so. We can't make joints that precise, but anything that provides mechanical strength or a larger gluing surface will help a lot.
