Relatively easy to use; has some quirks
12 December 2018
The pen itself feels good quality. It has weight to it, and the coating has a nice texture.
This is the first time I've used a 3D printing pen (or any 3D printing device), so I don't have much to compare it to.
The instructions were easy to follow. The only thing is the temperature setting is confusing. The minimum is 160 degrees. I don't know if that's celcius or fahrenheit. The instructions say that if there are bubbles or popping sounds when using the filament, to turn down the temperature, but doesn't give you an indicator of where to start.
So I figured I'd start at the minimum of 160 and go for there. It seemed to be mostly fine, though I got an occasional bubble. What I did find frustrating though, is that it was very difficult to make a line going upwards as the melted filament just kept bending over. I tried to slow the pen down (it has 8 speed settings), but even on the lowest, it still was difficult to make a line upwards ... let alone trying to make a coil shape or anything like that. If I tried to move slower, the stream of plastic just seemed to slowly pull away from the pen then.
My guess is the temperature was a bit too high for the included plastic, but I couldn't turn it down.
That said, I was eventually able to construct a box, but it wasn't easy. As mentioned, I have no comparison to other pens, so I don't know if this is normal or just this pen. It seems relatively normal I think (hence why it's 4 star not 3).
The other thing is that when you press the go button, it is continuous until you press it again. This is useful a lot of the time. But sometimes you just want it to go a little and stop when you let go. The pen allows you to do this by first double clicking the button, but it would've been better to have a separate button. And the placement of the faster slower buttons is unintuitive. It would be nice to be able to change the speed while you are "drawing".
The included pen holder requires a glass surface for the suction cup, otherwise it just falls over. The suction is quite good though. I actually ended pulling the suction cup off the base when I tried to pick it up when I was done. But it popped back on.
Overall, I think the pen does it's job and I'm able to make basic shapes and play around with it. Not sure that I'd have the patience (or skill) to make anything useful with it, but it's a bit of fun. Especially for artistic teens!
