Positron V3.2 as First Printer?
Positron V3.2 as First Printer?
Positron V3.2 foldable 3D printer designed to fit inside a standard filament box. Kit comes ready to assemble and includes a hard Pelican plastic travel case.
I am new to 3D printing, but have always wanted to get into it. Unfortunately, I have very limited space and no dedicated area that I could call my workshop. I also travel frequently, and I would like something where I could take it with me for the day.
Therefore, I would like a portable, or at least very small printer. AFAIK, the new Positron V3.2 is purpose-built to solve this kind of problem.
I am asking whether that model is a good idea for a beginner. My main concern is the price, which I am willing to put up with if there really is no other portable printer.
My other concern is just the fact that it is new and I may be too inexperienced with printers to deal with problems that are natural in first-gen products. I have a decent amount of experience soldering and other electronics work, but nothing with small moving parts. Also IDK if sourcing parts would be an issue.
If, in your experiences, these make it not worth it as a first printer, what would you recommend as a portable printer?
So much of 3d printing comes down to getting everything perfectly aligned and dialed in. On a foldable printer like this, I would expect you to spend a ton of time calibrating after every time you move it.
I think you're on the right track with not wanting to deal with the problems likely to come with a first gen printer. Unfortunately I can't recommend another product that fits your particular use case, maybe a https://bambulab.com/en-us/a1-mini but it's not as portable as that positron.
Agreed, imho calibration is the biggest issue. Also print times - generally I wouldn't leave a print job running (e.g. in hotel room whilst I'm out sightseeing) without being near or at least monitoring it. And finally the smell of some filaments can bother some people.
On the otherhand it looks really neat, the size is great and I think it'd be a good solution to your requirements. Just don't be surprised if you end up making a permanent space for it in order to avoid too much recalibration everytime you set it up 😂
And addressing your other concern, I think part of the original reprap ideal was that a 3D printer could print parts to build another printer, and parts to modify and improve itself. I've got a i3 clone and parts are usually generic and off the shelf - you might be able to check what parts it uses?
I just realized..... it looks like an upside down printer? The extruder is on the bottom on x/y sliders and the bed moves up. That feels like a bad idea to me, it'll make bed adhesion so much more important.

I'm skeptical of claims + quality
Goodness no.
It is such a cool little printer, but it is very much an enthusiast product. You'll find yourself doing way more tweaking and troubleshooting than printing. And support will be... thin. Also, the general body of 3D-printing knowledge is largely geared towards common styles of printer, which this is not.
I'd suggest going for a Bambu A1 Mini, Prusa Mini, or the like. If price is a concern, the Kingroon KP3s is a solid budget choice, but a bit more manual.
As a beginner, any printer geared towards enthusiasts will just be endlessly frustrating. My strong recommendation is to just go with something tried-and-true, and well-supported.
I don’t think I’d really view it as a typical first gen product; Kralyn has been working on it for quite a while and first showed it off 3 years ago. I saw a demo of LDO’s V3.2 at a RepRap Festival and it looks pretty solid.
I haven’t watched the videos in quite a while but I’m sure there are demos of bed leveling, which would be my only real concern with unpacking and repacking it frequently.
That said, since I haven’t owned one myself I can’t say “you should buy this!!1!”. Do you have the budget and time to start with another less-portable model at home to confirm you’re really into printing enough to spend the money on a positron? You don’t need a ton of space to store a Prusa MK4 when it’s not in use, and the robust frame plus fantastic bed probing mean there’s no calibration required after moving it.
