Friction welding....

Postby dkightley » Fri Jan 01, 2016 11:37 pm

I wasn't sure whether to post this on the back of the UV glue thread....or even in the 3D printing section, but I've come across a video on YouTube showing a rather novel way of fixing similar plastic parts (3D printed in PLA in the video) by friction welding.

Here's the video.....not sure if its of much use for some...but its worth knowing about:

I did have a go at trying the technique. It seems to work....but my RotoCraft drill's chuck doesn't have suitably sized collets to hold 1.75mm diameter filament without first wrapping in tape or similar....so its a pain feeding the filament out of the chuck as it gets used! I have some PTFE tube of possible suitable size on order which might solve the issue.

It needs some high intensity blue LEDs shining on the end of the filament that flash on and off at a high rate.....to give the effect of welding!! :D :D :D :D
