Now that's a useful tip! Makes sense to fuse with the same material.

Check out also super glue and baking soda - also pretty good for filling cracks like this.

Quick simple trick in a pinch, if this is something you do regularly tho something like 3d gloop is probably easier and stronger!

Actually, quite an innovative way. A well thought out-of-the box approach. I like it. Thanks. Would it be possible to make a "more scientific" assessment of the bonding/adhesion energy by comparing the adhesion force vs a chemical glue (epoxy) put at the same edge location? Now, of course the bonding effectiveness will depend on the materials we want to bond. Ideally, the material of what we want to bond should be the same plastic as the 3D printer filament.
@OMGTheCloud2 ай бұрын
Great idea! I'm not sure I have the equipment to measure the strength in a scientific way (other than me pulling on it until it breaks!). The goal and theory behind friction welding is as you mention: we are bonding the pieces using the same material and thermal adhesion properties as the part was originally formed from. If we think of this a bit in the "weakest link in the chain" concept, we do not gain any overall strength in the part by making the bond between them stronger than the overall 3D printed parts' layer adhesion. So, if we can make the bonded joint equally strong with friction welding, we've made the overall part as strong as it possibly can be :)
@therealaizensama2 ай бұрын
I guess that a priori if same materials are involved in the friction welding we should expect the highest bonding "potential" as if 3d printed however intuitively a deposit of molten filament vs a high friction speed does not enable the same entanglement of the polymers at the interface. For the normal 3D printing, there is some time left for the molten plastic to adhere with the lower layer with the help of gravity. For the friction approach, it is quite a sudden (i guess higher temperature than with the extruder) rearranging/melting of the plastic locally. You never know, might be that with a thermal camera to check at which rotation speed corresponds to the 3d printer extruder temperature. You can even plan for a DOE/publication/partnership with a university, because to me all what you are showing is subject to fields in tribology (applicable in many fields).

What kind of material do you use? Is it PLA, PETG, something else?
@OMGTheCloud2 ай бұрын
This is PLA. It should work equally well with other filament materials, just a matter of whether higher-temp filaments could benefit from running your rotary tool a bit faster!

I mean yes. But a 3d Pen would have been faster and maybe even cleaner if you do it right.
@OMGTheCloud2 ай бұрын
I’ve heard of those, but never tried one. Any suggestions? I wonder as far as structural strength, would a 3D pen also be melting the material on the pieces you are joining, or would it just sort of “inject” plastic into the crack? Could end up with a cold joint 🤔
@EvanzoZubinsky2 ай бұрын
@@OMGTheCloudI doubt it. 3d pen is basically hand held extruder, so bond strength is roughly the same as layer adhesion. Friction welding is probably stronger. I prefer fusing parts together using brush and DHM.
@OMGTheCloud2 ай бұрын
I’ll have to try that! Not familiar with the process, is that a solvent based solution?
@EvanzoZubinsky2 ай бұрын
@@OMGTheCloud Yes it is, dichloromethane is a solvent that disolves PLA just like acetone disolves ABS, it evaporates in seconds, so you've got to be quick: apply little bit of DHM on one of the surfaces, quickly press it to another and hold for 5-10 seconds, it will fuse together very fast, but it will take about half an hour for PLA-DHM mix to cure completely and reach it's full strength. Caution: DHM is moderately toxic, so it is recomended to use it in well ventilated room and use eye protection and gloves
