That's also a nice way to simulate a weld line on props that get painted to look like metal.

In metal friction welding (at least in all the friction welding processes I’ve seen), the material that turns and creates the friction isn’t sacrificial. It’s usually made of Tungsten Carbide, and is plunged into the two metals to be welded. So you end up with two pieces of metal essentially being stirred together by the carbide bit. As such, this looks more like friction gluing than friction welding to me, as it doesn’t appear that the two base pieces are actually melting and fusing together.

You might see better results by taking some inspiration from metal friction welding, and taking a steel rod or something which you use to melt the plastic and create the actual friction weld.

Chamfer both edges so it creates a valley for you to fill, you will get a better hold with a flatter finish

I am 60 years old and I remember a toy that I had MANY years ago as a child and it had a small tool that spun little plastic tips like this to "weld" together parts. It was so much fun creating with it. Nice to see someone used the idea. It looks like this is best used on solid parts, but it's one more tool and technique! :-)

3:30 you can just create a simple profile sketch and revolve around a centerline in most 3d modeling programs.

[Starvin]

this almost seems like a perfect mixture of the 3d pen and ironing technique in one, it adds filament while melting it together at the same time. gonna have to try this!

[Whisky.]

this might be a stupid question but would it "weld" better if yah preheat the 3d prints with a heat gun?

[doomdoomtv]

I've got a F1 helmet I'm working on for a costume but the model is too thick to get a head into. Could I use this technique to sort of sculpt the inside and thin it out while being able to also keep the parts together? I've got several spools of left over filament I can use

[Barbasnoo]

Awesome idea! I also have a ton of almost-empty filament spools. I took advantage of the Bambu Lab A1 Mini price drop and bought one (no AMS) just as a dedicated “last few meters” machine. I stack up the near-empty beside it, and any time I have a print where color doesn’t matter, I’ll feed it these last bits of filament so they don’t go to waste. Once one runs out, it simply pauses until I pass back by and load the next one.

[RegularOldDan]

Back when I started printing (over 7 years ago now 😳), I would just break or cut off a small bit of 1.75mm filament and insert it directly into the rotary collet you normally would stick tool posts into. The main issue with that, of course, is if there is that it doesn't take much of a bend in the filament to have it flounder on the end. It took some practice, but I got some decent welds.

[JonS]

I used this technique about a decade ago using short lengths of filament. I stopped using it because only short lengths of filament worked (long pieces wobbled) and so they ran out too quickly. This printed peg-based approach looks like a nice improvement.

I have also used the 3D printing pen (I backed the 2nd 3Doodler Kickstarter campaign just for that) and the special soldering iron tips that are part of the Modifi3d soldering iron-based tool. However, these days, I just tend to use 3DGloop, as it gives a cleaner finish without the risk of digging in to the print.

[daliasprints]

Lol can immediately see you do mostly cosplay scale stuff because those "almost empty" spools are my "weeks left" doing fine precision parts, miniatures, etc. 😂 Awesome idea in this video. I need to try it.

[Geeko]

I do friction welding as my job. Slower speed and more pressure to get deeper penetration. Ideally you want the material to mix across the seam.

[DarthCrumbie]

I'm sad uncle Jessy. I wanted to watch this video in particular to see how you attach these to the Dremel. But I don't know what you mean by "bare bones bit" and the video was blurry. Are you talking about the drum sander attachment without the sanding drum?

[theVariedLife]

Very cool. I recently got into fff printing so this will come in handy. thanks

[ChanceRoth]

This is the best tip I've seen in years! Great hack.

[tedcogley]

Do you a good setting for a elegoo saturn S for high detail and ok speed

[sublimationman]

I'm 59 and when I was a kid (like 10) I had a friction welder for models, it was a small battery drill with these little nibs that would do just this. So it's a very old idea. Just looked it up, was called Spin Welder by Mattel.

[dffhdsgaming]

nice way to do connections
is the neptune 4 plus profile tuned for orca on your pateron

[elromanicobaby]

Couldnt u just get the filament sensor thing that stops it when it runs out and continue with another filament
