3: Water-Thin, non-flammable, very fast-setting solvent cement for bonding acrylicIt will also bond with other thermoplastics such as polystyrene, CAB (cellulose acetate butyrate), PETG (polyethylene terephthalate glycol) and polycarbonate to themselvesIt will not bond to cross linked acrylicsItem Package Dimension: 2.0" L x 2.0" W x 3.0" H
I use Scigrip #3 (https://www.amazon.com/SCIGRIP-10799-Acrylic-Solvent-Water-thin/dp/B00466V8F0) and am happy with the results. It dissolves the PLA so it's not actually glue so much as a solvent weld.
Three hairline cracks. One half inch crack on the section, one quarter inch crack on the barrel and another small one on the barrel. I'm thinking I'll use maybe this or this instead of the first link.
weld-on 3 and 4 are thinner than water - about as thin as ether. you'll want a syringe applicator for them.
It's a specific product. It's a solvent that 'melts' PLA and other plastics together. Forms a good bond and doesn't require as smooth a surface as super glue. That, and it cures really quickly.

If you're gluing two flat surfaces (a model cut in half), SCIGRIP 3 will work well.

It's water thin, and so when you put the two pieces together and apply the solvent, it wicks into the groove and chemically welds the two pieces. It also has a very short working time (under a minute). If you need longer, I think there's SCIGRIP 4 and others versions.
