Blue Ridge Models (the LSD-19 kit in the thread above) is a resin kit maker. Resin is best assembled with CA glue (super glue.) I don't know what material Bunker Studio prints in, but super glue is likely to be best for it as well.

The only thing plastic cement bonds well is styrene plastic, which is what plastic model kits are made from. It was developed for that purpose. It melts the styrene. When you put two styrene pieces together with it, they fuse where the glue has melted them and they both touch. (Bill refers to styrene plastic kits as mold injected, by the way.)

Most other materials will not react this way with plastic glue. It doesn't melt those materials like it does styrene. So, you don't get a good bond (if you get any bond.)

Resin kits that you find on the market are made from a 2-part resin material. When the 2 chemicals are mixed, poured into a mould, and allowed to dry, they harden to form the model parts. Plastic glue does not work on these because resin is not styrene. Plastic glue is only meant for styrene.

3D printed parts come in a large variety of materials. Some metals can be 3D printed. The most common materials found in 3D parts made for this hobby are resin, acrylic, and nylon. None of these is styrene, so styrene glue (plastic glue) is not for them. Super glue will bond all of them, and will also bond styrene as well. I have not tried Elmers, but as noted elsewhere for you by someone who has used it, it seems to also bond "universally" to all the common materials found in this hobby nowdays.

I note how you have said you don't want to use super glue. Some decades back, I was in exactly the same place...I did not want to be using it myself. However, all plastic cement is good for is the styrene plastic in a plastic model kit. These days, with all the other materials out there, you will need to go to super glue. I have actually used plastic cement to assemble my metal 1/2400 models. It does not melt/fuse the pieces together, but it will hold them in place. It is a weak bond. If I touch the parts, they fall off. Last Christmas, my new cat tangled with my 1/2400 collection, held together largely by plastic cement. Lots of little pieces resulted. I spent a couple weeks reassembling things with super glue. Still not "indestructible," but Much sturdier.

You should know that super glue comes in a variety of "thicknesses" (viscosities) from runny/watery to a thick gel. Most folks first/only experience with it is with the watery stuff. Certainly mine was. That stuff will turn people off to super glue pretty fast. The thicker gel, though, is closer to the the styrene glue you are used to. It dries slower, and does not flow in a mess all over the place. It has taken me some practice, but I now routinely use gel-type super glue contentedly enough.
