I'm a field service guy so I travel for work, and soon I'll be moving into a motorhome full time. The idea of having a 3D printer setup I that only takes up the space of basically 2-3 filament boxes when I'm not using it is very attractive for my motorhome plans, and to think I could chuck it and a spool in my checked bag and print parts on demand in field emergencies is really cool. I've known of the positron for a long time but I'm glad to see others so enthusiastic about it.
Same i work on turbines and have been wanting this as a kit sincs i have seen it
I’m wondering what’s an example of a situation where someone would need this / a 3D printer on demand as kit? Not in a way where I think it’s silly I just kind of want to justify getting one and am wondering what’s afew real world moments where someone will (even in a specific industry) would need one randomly/ or consistently
@@BigpapamoneymanMVPtypebeatI install and repair Electronics Manufacturing equipment (Pick and Place). Sometimes, customers have zero application experience, and the assemblies they have on hand may not be suitable for sending into the machine conveyors while I'm on site for training. If the customer has a 3D printer we can quickly print a carrier, but if they don't, I can just print some stands to use temporarily instead of the edge conveyor; if I had this thing in my luggage.
Big props for your contribution to this project, making the cnc parts available as a kit is a great step forward for the project making it way accessible to others. Very well done
Super that you're continuing the project! I checked Kralyn's page sometimes to see if progress was made
He left the project open for others, I’m mot sure he will personally update it
Why upside down should be the most asked question. Not “wouldnt it fall..”
Your build guide is the best resource for this project. Looking forward to more videos about it
*Just some improvement ideas*
One cool and easy way to make it lighter and portable is by using an external 140W USB C adapter, possibly GaN adapters because they are lighter and more efficient. Most people carry one for their laptops and phone anyway so this would save them some weight.
140W may not be enough to heat up the bed super quick but once it is up to the required temp, 140W should be enough to hold the temp. Maybe a detachable foam cover could be placed on the bed to trap some heat and reduce power usage.
I would like to know more about how the 90 degree extruder works. It seems like the most useful development from this project
while every one trying to avoid item not stick on the bed. you make it upside down no worry about the fall hahaha nice good job interesting
Such a well made project
Love this whole project. Keep up the great work.
I really want one of these, but I don’t really trust myself to build it myself. I would absolutely pay extra to have a fully assembled version to buy online.
A possible solution would be using polycarbonate instead of cnc parts. Polycarbonate can withstand 100c without any decrease in stiffness. As well as, being quite affordable and a lot lighter.
Cut sheet aluminum/steel would also be good alternatives for getting price down. Milling is the last option you should be looking at if you want to scale a product.
This is so GOOD!
thank you for this incredible contribution to the 3D community
i always wanted to try one of these just for how different it was designed from all the printers ive used on top of it printing upside down.
ok but make one that fits inside the hole of a filament spool and draws from that filament
What happened to Kralyn3D? He just stopped posting videos
Im pretty sure he is just busy with work
Rumor has it he got a really good job because of the positron video.
He stated in his discord server, that he god a job in a 3D printer manufacturer company, but he had to sign a non-competence agreement, which disallowed him to develop Positron project himself, but the community got on to it
Is he the same guy that posted the upside down printer on RepRap Forum Many Years Ago? or did he take the idea & Run with it?
@@leonidmeleshin4227 I think you meant to say compete 😅
I've always been a bit confused by the Positron project, I want to like the idea, but it doesn't seem to do... well... anything. The main idea seems to be to create a portable printer right, but teardown seems very finicky and it 'folds' into a bit of a mess, has wires and steppers sticking out everywhere, with may steps to accomplish setup/teardown, and I have no faith the z axis works reliably after teardown/setup. It seems like you can just take a small bedslinger, and it will be better in every way to this thing, even portability is very similar (just remove z axis, like how slingers ship)
The printer is designed to be compact and light weight for easy travel. Other printers are not designed to fold. Sure you could disassemble a bed slinger but it wouldn’t be as easy as un screwing to thumb screws.
The z axis is very reliable. Many people who have build this printer have used it for travel and had no problems with its reliability.
Many printers have cable sleeves to connect the electronics to the main board. The stepper motors are also within the base of the printer.
The main benefit or use case seems to be travel, it would be hard to find a 3d printer that could be brought on a plane and to a remote location and be able to print no matter where
I agree. Good for the industry, but I think everyone loves the novelty. I haven’t had the need to print on a plane or car. And I would rather not lose my Precheck due to a misunderstanding with this very suspicious looking device 😂
AMAZING!
Building my AliExpress cart right now. There isn't a word in any language to describe how cool this whole project is!
Is this in a better than the coreXY movement? Why are you building this over other kinds of builds?
It fits in filament box, its the main goal of this printer
@@raiden72 I don't have the room or need for a full sized printer anymore since I don't do as much printing as I used to. I've been dreaming of a portable printer since I got into the hobby, but only just started seriously looking into it now that I've moved into a smaller space.
This will solve all my problems by letting me have it out for the few days I need it for whatever projects I'm working on, then chuck it under my bed when I'm done.
The cool factor can't be denied, either ;) will definitely have this set up and folded out for no reason when friends are over LOL
I have now almost got enough and seriously considering this as my 2nd printer
I'm glad to see more content from Positron, I love this project but it's so expensive... Especially if you live in Latin America and it's difficult to import 70% of what you need, starting with glass and heating. Is it possible to change the glass for another option? Where can I find more information? Thanks for the video, greetings from Bolivia.
Check out our discord and website about section.
The positron LT team is working on a PCB heated bed but I believe this is some time away.
Oh boy, i wonder if it could be possible to make that printer run from a 12v car plug !
Imagine, printing during a trip !
Why?
I really like this printer i saw the original design when it came out and this version looks even better. One question, what does a failed print look like. Im usually not too far away from ny current printer when I'm making things but wanted to know what happens with this printer if there's a failed layer. Also how does bridging/ support material work?
Fails just like any other printer might. Supports also function just as any other print. Over handing is actually better. Check out our discord to see some peoples printing results
@@mcfazio4283 What happens if say a belt slips or for whatever reason it starts printing in mid air? On an right side up printer the plastic will either drop down or start blobbing onto the printhead. I can imagine it will much more likely blob onto the print head and maybe make a bit more of a mess?
I wish you lived in my home state of California. We need someone like you.
One issue I see with printing upside down is bridging and overhangs. Instead of drooping down, usupported material droops "up" potentially catching on the nozzle on the next layer. Do you have to adjust your design and slicing for this printer, or is this a non-issue?
Bridging and overhangs are actually improved when printing upside down
how hard is it to source the need parts to build one? if i could get most of the parts i can managed to make the cnc parts with what i have but id love to try one.

This is an awesome project. I made my own JourneyMaker printer and I would highly recommend it to others. This is the best Positron Printer available!
Great video!
Maybe changing to a magnetic rail system would make the printer easier to make portable?
3D-Print your gun ON the plane with this new 3D-Printer
LoL
This is a silly project.
i neeedd itt...
Thats insane! Exactly what the inventor wanted to see!
NGL I was expecting the PCBway segue after the CNC machining cost mention
This is an incredible project though mate, I’m tempted to look at tech like this for my capstone after you mentioning it
Great work
ok. But other than collapsible size are there advantages to printing upside down?
Yes! Have a low centre of gravity allows the printer to be light weight, thus removing the need for a heavy frame to reduce vibrations. It also allows the printer to achieve faster speeds.
I bet we will see more upside down printers in the future
@@mcfazio4283 but since vibrations arent an issue with rigid frame structures why should we limit the size of our printer? It seems like a great experiment, but for people hunting for quality on a budget but also have big parts theyd be left out
This is great! 🎉
GREAT thanks!
If the size of the CNC parts is below 10X10CM. you could use JLCBPCB/PCBWAY to produce them
using PCB is cheaper than using other CNC parts.
Maybe
4”x4” ? Pretty small
Good job! Canadian proud! 🇨🇦
That bed holder fork part looks like it could be made out of wood for almost no cost. Just a couple sticks and some flat pieces glued across the grain to join them together. May need bulked up a bit for stiffness, but I see no issues with that. The tower would probably be fine in wood too.
that's so sick, thank you for all you did (although it's still pretty costy, but yeah)
I’m wondering what’s an example of a situation where someone would need this / a 3D printer on demand as kit? Not in a way where I think it’s silly I just kind of want to justify getting one and am wondering what’s afew real world moments where someone will (even in a specific industry) would need one randomly/ or consistently
For example: on site car repair for vintage cars (but you could just get data, send it to your shop/office and print in fixed place, send it instead. But that is more complicated but less likely your portable printer will break on site ruining the job¿ 🤷🏻♂️🤔)
The revision to the magnet connection does, on the outside, seem better but I have a feeling that it will create further issues in the future. That's quite a lot of resistance on the connector and a small window of opportunity for the pcb connection coming off the plate to perfectly align and slide into the opposing connection. On top of that I'd imagine a press fit / tension connector like that likely can't withstand tons of repeated removal and insertion. I'd weigh your options and continue to look around and find something that may be a bit more accessible and easily repairable / replaceable. Personally using some sort of ribbon style pcb(s) with magnetic connections may be a good route to look into. A lot of keyboard designers have implemented this into their cases to connect the pcb to the usb-c port.
My friend lives in a very small apartment and has no place to put a regular printer. I'll probably put it together for his birthday. He will definitely be happy.))))
Definitely a Canadian. Sounds American but pronounced Z as “zed” rather than “zee”
What CAD software is that?
Onshape
Sodder as in butfk?
How does bed leveling work on this design?
It uses an IR probe on the tool head. New design is coming with a BL touch.
Ay! A kiwi! Don’t suppose you ship from NZ do you?
The printer on the plane is from someone in NZ
Which cad software you use
OnShape
Very cool printer
I think printing upside down is a cool idea. But other than making the machine more portable, I cant see why printing upside down would be more beneficial compared to a traditional core XY or bed slinger. If it improves print quality, print speed or eliminates the need for support then I can see the appeal. But it doesnt which is why I see this more like a gimmick and less as a viable option for day to day 3d printing, still a cool idea tho.
Well it improves bridging. A dialed in printer can do good bridging. But supporting the extending strand with the nozzle against gravity is a definite bonus. Once dialed in it'd probably be the best. But yeah, I think portability is the selling point. Having the lower center of gravity for the extruder and head means way less vibrational forces and artifacts. Would be kinda interested in an upside down coreXY now XD
If that’s the case, then sure I can see the appeal :)
@@Titan-un3zu yeah. It's rare the manufacturing mechanics allow it. The only other super common places motion systems tend to be bottom mounted are laser-based resin (formlabs) and CNCs. Obviously bridging isn't a thing there tho, but center of gravity matters
Low centre of gravity is the main factor with it being inverted.
-reduced weight
-reduced vibrations
- faster speeds
Much more
If it was battery powered I would buy it.
In the video you cite the JourneyMaker as being more accessible than other versions of the Positron, however the LT heavily pulls from marketplaces such as aliexpress and uses 3d printed parts, your JourneyMaker variant relies on purchasing CNC'd and other custom parts from your store.
This seems like a step backwards from what the LT team has done with the original Positron V3, in moving away from custom fabrication, and towards easily sourcable/printable components.
Do you have a justification for this decision?
By providing readily available custom parts, we simplify the build compared to the LT, which requires cutting makerbeams. Ultimately, this approach aims to make the Positron more accessible to a wider audience
Ugh, sick of the word “maker”
I might join this discord. Don’t have much to contribute, but I want to get into 3D printing so I’ll lurk and learn
great vid but please start using a script, you keep saying stuff like "the" and "um" alot
I was in a constant state of pog throughout this entire video lmao
I love seeing all the Positron variants pop up on TH-cam. I do have a question: Is anyone in the community working on a Positron Mini? I feel like it would be possible and very helpful for makers with very small spaces.
I believe someone has. It is not the exact same form factor as the Positron, but it is a smaller version. You can find it in the krylan discord server
Are you living in a refrigerator box? How small of a space are you in that this one is too big? 😂
That “maker” should focus on making their living space bigger 😂
Question is, why? What's better than for example the brand new Ender 3 V3 CoreXZ ? Like, does the price justify the mean? Seems overpriced for just portability.
Its a very compact design. Its also not being stream lined manufactured so cost is more expensive with self sourcing kits.
Just because portability doesn’t matter to you doesn’t mean it doesn’t matter to others lol
@@Resyektt The portability part is overrated, IMO. Very niche use case.
@@_..-.._..-.._ I do agree, but that’s also why it’s being built by a community rather than a company, because it is in essence for a niche demographic, therefore a company has nothing to gain producing it where as a community of the exact people who make that niche do
What is this weird comparison? An ender 3 and this printer fill entirely different niches. This is like asking someone why they'd buy a smart car instead of a truck.
it would be sick if you could make a built in battery pack that is maybe detachable for the ultimate portability.
Huh!
I had a lot of trouble following you but I'm a blonde so there's that...
The Y axis needs 2 rails otherwise the performance will take a huge hit. With 2 rails it should print at least 2-4x faster.
Right now it's resting on a single rail with the toolhead swinging around on a 8mm or 10mm wide track. Jm2c.
I mean more rails will always improve performance (assuming you can get them to line up exactly), but there's plenty of single rail systems, like annex k3, which has no issue with speed. Could you explain why this is more relevant in this case?
@@ZeeLobby The K3 doesn't ride on a single rail... it's a cross gantry core xy machine the motion dynamics are completly different.
@@hd-be7di right. And in this case the rail is fixed to the frame itself. So I'm not sure why it'd be any more wobbly. Unless your using some shitty rails
Sounds like an interesting idea. Might be a little hard to fit a second rail in there with how compact it is. The CAD is available on GitHub, I encourage you to give it try. Could be pretty cool.
Do you have any idea how well hiwin-style linear rails work? They’re extremely accurate and can probably hold 1000 times the load that this project is capable of doing. The carriages and rails are also extremely heavy. Two rails would be pointless and offer no benefit. There’s a limit to how fast FDM printers can print before the time savings just isn’t worth the violence of the accelerations and wear and tear and poor performance.
Why not use corexy?
It uses the same principals for corexy but in a inverted H bot design. This is to maximize the print area
It’s closer to coreXY than a bed slinger.
oh no i started my print welp gotta sit here for 23 hours lmao.
???
You couldn’t possibly print something that time-consuming on a machine this small. And if you are, your scheduling needs improvement.
bruh it was a joke calm tf down buck 'o@@_..-.._..-.._
nice video but the quality of the vid is really bad, it looks like 720p washed out
Ya my recording software isn’t the best
720 isn’t that bad, kiddo. You just have too high standards for free content. Go watch cartoons on a 1980’s tv with static and 120p and get back to us.

$403.00 CAD? too expensive, thanks.
Nice gimmick but absolutely useless. Too small, too imprecise. If there is no liability, the catastrophe is complete. Nobody needs a 3D printer to transport. Simply print at home and take the printed part with you. Pointless...
Guess we all know what not to get you for your birthday 😂 it’s not for you, you’re not the demographic. That’s ok. Neither your use case or the project are wrong in their aims or opinions.
I take my Voron v0 and micron to work with me sometimes when I’m working on projects since I can just remove my printed parts and start the next print at work and could knock out an additional 5-8 prints while working. Good to know you think this is useless cause that just frees up parts for me.
