Rather than toss a few collecting rolls with a couple meters of filament left, I got looking at 3DP pens. They look kind of cheap & mostly what I see is scribble art, maybe suggesting lack of control. Could one for example weld parts together in certain applications or any other useful purpose?

Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

I bought a couple in the last few years, mostly as you say they are cheap the first one the switch went wonky after months but the second has been good. My daughter mostly used it for adding to something already made/creating. I did try to weld some things together with success but the temp had to be way up with a lower flow to get a decent bond which made it slow a slow process for anything bigger than tacking together. It is good for using up those last bits of filament.
A million years ago when I was a lad I received a spin welder kit for xmas you spun these plastic welding rods and built the frame of a race car out of it, the kicker the spinner after building it was used to propel it genius!

The Mattel Spinwelder Was the Coolest Christmas Gift of the 1970s - BestRide
Flash back to 1974. I was six years old, and Santa Claus arrived at my house with a sack full of socks, long underpants and pajamas. But in the far back corner was a rectangular box that rattled when you shook it, indicating goodness inside. It was a Spinwelder, and I was the luckiest kid […]
I have a cheap one of Amazon. Most I’ve used it for was to add different colour accents to stuff. Like white eyes on a small figure. Have not used it for years after figuring out how to slice and pause at height for colour changes.
Never used the for gluing. I use plastic epoxy for out door stuff and cyano glue for everything else. Now I try to make the parts lock together or use printed pins, even large threads.

My Son got one for Christmas. Pretty neat, limited uses though, But not terribly expensive if you want to pick one up and play around with it for various duties to see if it'll work how you want. I was kinda hoping I could use it to repair 3d prints for patterns, or build up features on existing prints to shape and sculpt but I struggled with adhesion problems. https://canadianhobbymetalworkers.com/threads/3d-printer-pens.13488/#post-179817
He still plays around with it periodically. It works pretty good tracing out a shape on a flat surface and then building it up in 3d. The material sticks to itself pretty good, I just couldn't get it to stick to older prints, and have not played with it much more since the initial tests.
