Hot glue can be slow to cool completely, and will always have a bit of flexibility to it. It’s a workable process, but I felt that hot glue just wasn’t the right thing to use in this case.

Let the hot glue cool and harden, and repeat. The idea would be to hold two pieces with the presentation sides lined up properly with each other, then anchor the seams together by applying melted glue on the inside (non-presentation) side of the joint. A hot glue gun is worth considering for a job like this. On top of it all, the curved surfaces meant clamping was impractical, and any movement of the pieces while gluing would result in other pieces not lining up.Īn advantage was that only the outside of my hollow model was a presentation surface the inside could be ugly. These were essentially butt joints on all sides - the weakest kind of joint - offering very little surface for gluing. I now had a large number of curved, thin-walled pieces that needed to be connected flush with one another. In this case I had recently segmented a large, hollow, 3D model into smaller 3D-printer-sized pieces and printed them all out, but found myself with a problem. Some solutions come from no more than looking at two dissimilar things while in the right mindset, and realizing they can be mashed together. But it wasn’t quite as simple as shoving scrap PLA into a hot glue gun and mashing the trigger a few glitches needed to be ironed out. The result is a bit like a plus-sized 3D-printing pen, but much simpler and capable of much heavier extrusion.

When is a hot glue stick not a hot glue stick? When it’s PLA, of course! A glue gun that dispenses molten PLA instead of hot glue turned out to be a handy tool for joining 3D-printed objects together, once I had figured out how to print my own “glue” sticks out of PLA.
