To expand on methods to stick parts together, two topics I'd like to hear about are: creating interlocking features that jam together robustly. And techniques for welding parts together with heat, either by heating one or both surfaces, or by applying hot filler material from say a 3d filament "pen", like MIG welding steel. Oh I guess there's also friction welding.

once you include welding type bonds it becomes hard to argue against acetone welding on ABS there are also modelmaking glues that also work that way. dissolve the surface so that the two plastic parts literally become one and then harden again by evaporating the solvent. usability depends on the type of plastic though....

I actually repair broken prints with a 3d pen and it's very tricky to do. You need to touch/heat both surfaces before you extrude the filter material. Or else it won't transfer enough heat to actually melt everything together. But if you manage to get it done, you end up with sanding a perfekt bond.

I've gone through a lot of adhesives and solvents trying to find what works for me with various materials and uses. For me, CA (esp. Loctite Ultra gel) works a treat with PLA and adequately with most PETGs. Epoxy (yay JB weld) is very solid if not too thinly applied with just about everything. If I really need strength, it's solvents e.g. Weld-on 3 or 4 (I like 4 for PETG). When working with TPU, which admittedly I haven't done a lot, I've found Loctite 406 (with or without primer) to be almost as good as a solvent (being a CA, also works with PLA and PETG). For a solvent, I used DMF once and it welded TPU great (I hear THF also works but I haven't tested it). I mostly stick (ha!) with 406 since it's more versatile for me.

There are Thin, Medium, and Thick variations, as well as some which are rubber toughened. I typically use accelerators with them, but not always. Accelerators can cause glues to boil and bubble in some situations causing aerated volume increase. I'm eager to see how it works with PETG. My favorite CA so far is Starbond. They have a great variety, and I keep all four I mentioned at the ready.

Since I am a bit professional in the field of plastics, I would have to comment that any kind of bonding is depending a lot on preparation of surface i.e. it has to be dust clean, de-greased and without any other contaminants. Apart from that superglue (cyanoacrylat) is reacting with airmoisture, that starts curing process. I could see that some of the guys in the comments are using quite industrial grades of bonding material that I know from my time in wind turbine blade manufacturing and that is great. Just please remember to be safe, also when we are talking about use of epoxy (that personally adore as manufacturing material) and PUR. So keep creating but be safe as well!

I've also finally started using the 3D Gloop! I bought a while ago and never really used. So long as you clamp the part it work amazingly well (the PLA breaks first). VHB is a pressure-sensitive adhesive, so really needs to be clamped to get the best results. I still won't work well under shear though.

For PLA, acrylic glue (solvent based cement for glueing plexiglas/PMMA) works well - it seems the solvent used for PMMA/acrylic also dissolves PLA, and creates a strong weld bond. This is a one-component glue that's sold in the hardware store as a squeeze tube, so it's a bit less hassle than 2-component glues.

In the UK there's Araldite, globally 3M Scotch-Weld, Loctite (but those are usually more industrial use) and I'm sure there's a fairly generic one in Germany too.

I don't often have curvy/gaps in my parts, so it's nice to see that CA generally ends up being stronger than the parts themselves.

VHB Tape is a hell of an adhesive for 3D printed parts - you just have to read the specs and get the right one! I'm printing (in PETG) mounts for a little electronic dashboard device for motorcycles and those attach with VHB tape so well that a) it's nearly impossible to remove (unless you use the right technique, which involves dental floss), and b) the tape comes off the aluminium on the motorcycle side first. The trick to finding the right VHB tape is knowing the surface energy of your material, wether it's high or low. 3M has pretty good documentation on that. Oh, and then you of course need to get the right thickness, so that the contact surface is as large as possible. For your curved test, you should have used tape that touches all edges, or even more, then you should have seen a much better result and no peeling back.

There's two more tests your really need to do to see the differences between the different glues: pulling directly against the glue surface, and dropping things from a moderate height. I say this because CA glue is SO strong for forces that are pulling on the joint - but it's also brittle and tends to shatter when subjected to shearing forces. So CA glue is fine for most things, until you drop it. Also: I love that you ran up against the challenges of ADR and just nerped out of it. :D

It is odd that the ‘None’ control performed better than the adhesives, considering that some of the tests broke at the plastic rather than the bond line. I wonder it VampCaff’s comment about the bonding agent affecting the plastic is a cause or if there are other factors involved? Since I print functional parts, bond or plastic degradation over time would be an important consideration in the choice of adhesives. Thanks for the work, Tom, appreciate it.

From my experience, going over the broken part with soldering iron, has a high chance to top the strength chart. Set temperature somewhere in the range of 110-210 C (depending on the stage, experiment), start with higher temp and use pointy tip and stab parts together couple times, then lower temperature and use knife tip to smooth the edges. I'm surprised I did not see any comments suggesting it.

Proper heat for layer adhesion is a big factor here too. If the room you are printing is too cold, the fans are too high or your nozzle temp is just not hot enough, then your prints will be weaker. Also of course the design of the print itself matters a lot too. Honestly 3d printing even with just PLA at 100% infill is very strong. When above 1/4 inch thicknesses. As will basically all things plastic, you need to go thicker and bigger to have really good strength. However not everything needs to be strong and that's where 3d printing really shines. You can make incredibly complex prints with very little infill, using clever infill techniques, to make insanely light things. But that isn't to say that they are so weak, that if you look at them wrong they will break but even if they do, it's relatively easy to glue or just so cheap you can print another one 😅

I found that 3M double stick Gray tape that it say can hold something like 30 lbs does not stick well at all. But the Clear 15 lbs 3M tape works well. I have only use the clear version on my Dayton Exciter speaker to stick to my cardboard cone but this works great. This version is the tape that comes on the Dayton Exciter speakers when you buy them.

THANK YOU! Finally someone proves resin as adhesive isn't good! I've been trying to tell people on any video I see it, the middle won't cure! Also, is E6000 a thing where you are? Here in the states, it bonds EVERYTHING!

The green screen thing was really creative and a really undisruptive way of correcting the mistake! Greetings from your neighbors to the west

Would be curious to know how something like E6000 would work with the various materials. Thanks for sharing!

Thomas, great job, I can't remember if I commented previously, but I use model makers [plastic kit] solvent weld which melts the touching surfaces - this is sold for Plastruct ABS extrusion material - I wondered if you excluded it because its not very nice stuff - but I'd love to know what the test results would be like. It works on PLA and PETG btw as well as ABS.
