Comment on What is the best (liquid) glue for gluing PLA prints together?

Cyanoacrylate, aka CA glue or superglue, is the best adhesive for PLA. After applying the glue, fixture or clamp together the parts you are planning to adhere and then leave them alone while the glue cures.

You can buy CA accelerant which dramatically reduces the curing time of super glue.

CA accelerant also acts as a primer. It’s a fucking life changing superpower!
I used to hate CA, except for some applications, but using accelerant makes CA much more viable.

You can also mix in baking soda to drastically increase the strength of the bond

Woah, do you know why this works?

Chemistry! (Beyond that, I’m not sure)

The baking soda catalyzes the CA polymerization by dropping the pH.

How much?

I just sprinkle it on, if it’s too much it can just be blown off.
It also helps to add structure to the bond. The baking soda can build up and add strength.

Totally. I prefer to have a little cure time to get things set and aligned properly, for some reason it nakes me feel panic-y when the set time is super quick lol.
