This Little 3D Printer Might Just Change the World...

[@fabianbahr]

Hey guys, i'm currently testing the LDO Beta Kit as well and wanted to add some comments: - The bed is actually heated across the whole surface as it is coated with a conductive ITO layer, so you get fairly even bed heating on it - The oozing on print start can be fairly easily fixed with adjusting the print start macro, it is definitely oozing more than other hotends - The max flowrate i was able to get was about 20mm³/s with an aliexpress cht nozzle and PLA at 220°C - Accelerations and speeds can be tuned pretty well, travel at 500mm/s and acceleration of 15k is not an issue. Inputshaper helps a ton, an ADXL sensor is already on the USB board - The heater the nozzle came with is too weak, i replaced mine with a Bambu Lab ceramic heater (LDO uses the same type) and it works just fine for PLA, PETG and potentially for ABS - If you are looking for a more RepRap style and cheaper alternative, might want to check out the Positron LT :) If you got any more questions, let me know 👌👌

[@Guy_Sandler]

Thanks

[@thenextlayer]

Wow! Great comment! I will try the Bambu heater fix!!! I’m also gonna pin this comment!!

[@fabianbahr]

@@thenextlayer make sure to extend the cables by a few cm before installing as the bambu cables are too short. Check that the heater is tight against the hot end as the metal clip was manufactured incorrectly and might not tighten the heater fully (this has been fixed but your unit might not have the updated clip)

[@42436freak]

didn't slice or e3d come up with a positron specific hotend?

OMG you got a Positron! I've been wanting to build one of those since seeing it a year or so ago. Looks wild!

[@LoverTerminator]

I live in a van, and have used 3D printing to make some specific parts for my camper build. This would be sick, as the bumpy trails would destroy any typical 3D printer, let alone the space it takes up.

[@BenWolkWeiss]

Johnathan, thanks for adding in the voice over for the chapter titles! I noticed the difference while watching this as i got ready for work this morning. It was much easier to follow along between segments when i wasn't directly looking at my phone. Some of the transitions needed a bit of polish as there were a couple of repeated phrases but I'm sure you'll work that out in your scripts for next time. Awesome video and thanks for covering this unique printer.

[@thenextlayer]

I had you in mind!!

[@BenWolkWeiss]

@@thenextlayer Aww shucks, thanks!

[@dennisleet]

Oh yez! I have been following this for about 2 years now, and am very close to pulling the trigger. I am mostly waiting for a few real world reviews. Thank you for yours.

For anyone interested - I'm the Project Manager of the Positron Project, I'm happy to answer any questions that anyone may have.

[@matthewdeluna7810]

What is the final power supply specs? Voltage / current? Thanks!

[@abowden556]

What kind of BOM cost reductions are in the future for the DIY version? Are you planning to go the way of the all in one printed baseplate with integrated extruder? are you guys planning on upping the power of the hotend?

[@martslittlediyshop8670]

Man, this is going to be a first aid kit for emergencies around the world. 3D printing and fixing on the spot, cool.

[@erin.anderson]

I am not the audience for this product, but when you mentioned "changing the world" I immediately saw where you were going to go with that, and I could not agree more. I could also see this being great for presenters on various convention circuits. It is fast enough that you could realistically showcase it doing prints live, while remaining ultra portable. This is a very exciting product, honestly, and I look forward to seeing how it progresses.

[@DaveDarin]

Well, I'm a VORON guy, a recent VORON guy. Plus I am a DIY guy who now has twelve 3D Printers, of which 9 of them I got on eBay marked "as is, for parts only". I bought them super inexpensively, $100-$300 and used them as a learning experience. So, I have a wide collection which included Lulzbot Taz 5's where the owners must have taken the entire structures apart, for some reason, and the entire printer was not squared off so stepper motors would jam. Also the printers Rambo card was completely miswired and, as a result, 2 of the onboard fuses were blown. One of the drive screw supports were upside down and build plate shattered. I could go on and on. I also have Snapmaker A350's. Same thing , lots of issues. But having bought these printers for $100-$300 and spending around $100 in parts BUT some significant time (which was a cool learning experience) I now have all the printers working. So, yes I will probably buy one of these as it's the engineering I am interested in, for sure. Nice review.

[@nikolus24]

I've been following this project since the start! I can't wait to see the production model!

[@SnepBlepVR]

I just hope its not a bank breaker

[@MarieLuiseOrland]

I went to same conferences for open source and brought my ender3 with me. It's such a hazzle to find a secure place for it in the car. So an easy transportable printer is sitting at the top of my next printer list.

[@3DPrintSOS]

There’s so much cool innovation in this machine. If not individually, then together in this configuration. Super cool.

[@3DPrince-zd1se]

Glad to see others posting about Positron builds 🤝Excited to see the project continue to get traction!

[@AlfredoAntonioMartinez]

Totally stupid question , but it is possible to use any kind of support to be able to use the printer in the traditional way? have you tried to print in traditional way? I really love the printer, the project, everything, but using the printer in that way makes my brain get pain XD

[@thenextlayer]

It prints like any other printer supports and all.

[@AlfredoAntonioMartinez]

@@thenextlayer No, I mean, sorry because I don't speak alot of english, I was thinking about to use the printer maybe in my job and in my home, and maybe in both places have any kind of structure to hold the printer in the normal way, and them, can be remover and folded to make the travel more comfortable,,

[@KennethScharf]

Reminds me of a walkman cassette player that Sony made that was designed to be no bigger than a cassette box.

I've been following this project for a couple of years now, and it's amazing to see it about to be an actual product! Very cool.

[@SquintyGears]

Putting the head in the base and lifting the bed is absolutely brilliant. The speeds would be completely unrealistic if it was on a gantry. But this way it's always in the most rigid place, there won't be ghosting and wobble in the print from the head acceleration except if it drag on the previous layer.

[@spudtree]

Woah looks like I found my next printer

[@ThePrintHouse]

One time I brought my WizMaker P1 on an airplane in my suitcase, but yeah this one takes it to a new level

[@stevemather8873]

I'm a noob to 3d printing I would love to learn how to build my first 3d printer in a way which is mobile like the ldo positron that would be like a dream learning project.

[@smorrow]

I don't buy that being really portable is "world-changing". Seeing the claim in the title, I thought the argument was going to be: this is the printer for people who _would_ like a printer but expect to maybe use it like twice a year some years, so can't justify it if it's constantly taking up space while not in use. The same principle on which everyone _does_ have let's say a drill and does _not_ have a bunch of kitchen unitaskers (or even one). So it's good not because it's portable but because it's stowable, the upstream trait of being portable.

[@RanaLoca]

Something to note, you mentioned that you couldnt print petg because the hot end couldn't get hot enough, that might have saved you. Petg is known to break glass beds during removal because it sticks too well.

[@HReality]

Been watching this for awhile.. as soon as its available Im all over it. 3 Vorons, 2 Ratrigs, 3 Prusa models and even two Bambu I honestly think this becomes the 'go to on the go'.

[@skovbo65]

It will also be a great printer for people who don't have the room for permanent setup of a printer when they don't need to print nonestop like if you only need 1 or 2 print per week then you can pack it up and store it when not in use.

[@smorrow]

But is that a side benefit or is that the true world-changing bit?

[@AerialWaviator]

Nice to see such innovation progressing to next stage. Saw the original kralyn3d concept for the Positron two years ago. Very impressive then, more so now. Explains why the channel went into stealth mode. To shrink size for portability will retaining most all the quality, while adding even more flexibility. I'd imagine there is also opportunity to optimize slicers for this new inverted style of printing. (eg: rethinking how infill is applied) Also love that its not a bed slinger, so print is not exposed to constant accelerations, just a slow z-motion. Personally don't see the need to have print bed rotated 45º. Know they are trying to maximize print volume, but aligning to base would simplify the design and setup. Even if base was rectangle vs. square print bed. (less complexity, less handling)

[@marty4286]

I've been following the Positron for a while, but not too closely, and it's come so far in just a year!

[@owenpatrick874]

I've been really excited for this since I saw their first video. I'm a lil sad that some of their initial unique build pieces didn't make it through, but still love the idea and can't wait to order a kit.

[@TS_Mind_Swept]

I probably wouldn't get one of these, but I appreciate the portability aspect of it whilst trying to maintain a level of quality

[@weltonbarbosa206]

Im literaly one of those use cases. offshore/remote oil rig. Max payload i can care is 15kg including personal stuff … so... i would love to have a 3d printer with me, just cant.

[@mattlberge]

Amazing concept. As someone who doesn't go too far from home I don't need the portability but your right that there is a huge market for this

[@clb1024]

I ran across the story of this printer a while back. Very very interesting, however I couldn't find anything about it later. I greatly appreciate your honesty about LDO and your relationship. I got a very honest opinion vibe even when you talked about failed prints.

[@thenextlayer]

Thanks for the feedback. I’ll keep it up

[@creekboys6939]

I'm so glad this printer made it through to the product phase!

[@S_Chand13r]

I love this concept! I’d seen quick blurbs about this recently, but had no clue what it was. As you pointed out, this is something that could be quite handy in “out of the way” locations. While my Ender may be great for at home, I’ve found the occasional need to print repairs when visiting my parents river home. Instead of weeks (or months) going back and forth with prototyping and testing, this setup would allow everything to be done ON SITE. I look forward to see where this ends up going, and how it changes.

[@IronFairy]

Is this version based on the Positron LT?

[@ldomotorsjason3488]

Partial LT design - mainly on 3mn belt concept; LT team on our tester group. We have taken inspiration from all feedback we've received on how to improve the design. This includes feedback from the LT Team

[@ZeeLobby]

@@ldomotorsjason3488 So the one in this vid has synchromesh. Does that mean the final kit is diff from this one and replaces it with belts?

I discovered your channel just a few days ago and so far really like everything that I have seen. And now there is a video on the Positron V3... amazing! (actually considering to subscribe 😜). I've been interested in that printer for a while but I am not an early adopter and there were no information on that thing apart from the scarce official resources. So thanks for the video and sheding some light on that cool little printer! :D

I'd be interested in this for printing funcional replacement parts on-site/while on route. But I'd need it to be able to print nylon and PCCF. The price is a hard thing to swallow but not a dealbreaker. Capabilities unfortunately are.

[@nicksmith1415]

Cool Vid fella. It's great finally seeing this come to market. I watched the touching and really interesting vid on the lad who developed it, touch of genius. Seeing it in person at SMRRF was awesome. My daughter and I were entranced. I think students would benefit and can easily see it coming in useful for on-site jobs.

[@HappyZentraedi]

I've been waiting for the Positron to be a kit since I heard about it a year or so ago, and I hope to pick one up when they become available. I want to take it to my mother's and pack it away there so it doesn't intrude on her space when I'm not visiting. It would make it much easier to go through the repair list when I'm there.

[@thenextlayer]

Bingo!

[@nemorianderson]

I've been amazed on this design since the time Kraylin released his first positron video. And I actually got most of the parts to assemble a couple of them, just don't quite have time for that currently. About the niesh uses and work in field I think a lot of people are missing something. Like most when they see it immediately assume "Wow, I can fit one to my backpack, that means that now I can 3D print everywhere?" Well, yes, but not quite. First of all you obviously do need electricity for it to work, and this thing is quite hungry. So at least at the moment you will also need an Ecoflow or something if you want to print in a place with no electricity. Second thing that people miss, that technically yes, you can print everywhere with the printer itself, but only things which you have already pre sliced as gcode. Which by itself is also a lot, don't get me wrong. But in order to actually print a specific part for a situation you didn't know in advance, you also need a laptop with some type of CAD, part modelling skills, a slicer, and probably internet. And also don't forget you need filament, and depending on printing amount the spool can take an extra kilo or 3. Combined with the fact that you also need Ecoflow or similar, that brings us more to a kit transported by a car rather then by person on foot. And if so, with big enough car especially if you configure it for a specific reason, that means you can toss any printer in this setup and it will work portably just fine. Like you drive somewhere, need to print something there, and have a printer seted up in your car and maybe even a workplace where you can sit, model, print, and probably make some post processing. Third thing about "field work" that most people are missing - field is not a very clean place. You have dirt everywhere, wind, sand, dust, moisture, bugs and sometimes mise and rats. I have a few friends in military here in Ukraine, and speaking of Ecoflow, which they are using a lot, they have a huge drawback for field and tranches. Because they are based on cooling by air, the fans ane constantly sucking in a lot of dust, and becomes stuffed with it way too quickly. And if you didn't notice in time - the device overheats and dies in about a week of hard conditions. I do believe that position has a huge potential, but in order to be truly portable all this thing need to be considered

[@3DWolfEngineering]

Ironically i was just looking into that printer when youtube pinged me about this video... Everytime i am on vaccation i miss my 3DPrinter's and also always think with every problem i encounter - what if i could just print it now as i do at home ? Thank you for that great video saved me some time looking into it (and it came exactly at the right time xD) Funny there is a speed run for assembling it... If it becomes available and i get one myself (very likely just a matter of time/budget 😅)... then i am absolutely up for a speed run and especially speed printing with it - the low center of gravity and the overall design are very interesting... With a few mods as you mentioned, like nozzle scrubber and others this will be a very nice printer for Travelling... althought with the upside down my fear for hotend blobs gets quite a bit of boosting😬 Hope i can one day get my hands on this thing... All we need now is a portable filament recycling station so there is no need to bring the filament to remote locations... (and before haters start replying saying i am just some guy giving ideas and i got no plan of it all, i am currently still a student (mechanical engineering) and therefore miss budget to bring all these to reality and i can currently just do a few of my projects one at a time but will absolutely do it in the future) Stay save and thank you again for that great video ❤

[@thenextlayer]

Yeah, the needing to carry around heavy filament is a bit of an unsolved issue. Though you could probably print PET bottles with a compact setup, as you said. Thanks for the comment!

[@coolcat312]

I've been following the progression of the Positron since Kralyn first started posting about it. I'd love to have one at some point so I'm hoping it is successful enough that pricing eventually comes down.

[@mrnlce7939]

I think it's very cool but the next evolution would be to incorporate the pelican case into the printer it's self. Making for an even bigger print volume. Great video. Keep up the good work.

[@thenextlayer]

That's a clever idea! But then again, think about if you DO want to put it in a backpack (maybe with a sleeve or something), you still can if it's not integrated into the case.

[@mrnlce7939]

[@sergeyirbis]

About heating))) Maybe the wire that goes to the heating block is somehow damaged or has loose connection to the board. So it cannot deliver enough current to the heater.

[@thenextlayer]

Thanks for the kind words. Maybe, but it works fine at 210!

[@sergeyirbis]

​@@thenextlayer I had a similar problem quite recently. The extruder warmed up slowly. And it barely reached 210 degrees. When trying to print faster, the temperature dropped and the klipper went into error. When trying to heat up to 235, there is also an error. Even when part cooling was turned on at 100%, the temperature began to drop. I changed the heater to a new one - and the problem was solved immediately. I examined the old one, and the wire at the entrance to the capsule almost came off. There was only a few thin wires left.

[@sergeyirbis]

@@thenextlayer Actually, in Klipper, you can change the sensitivity of thermal runaway protection)))) And the error will only appear with very strong temperature drops))) But you don't need to do this, of course)))

When will they release this kit? or will we be able to preorder anytime soon?

[@thenextlayer]

A few months max.

[@nateronipizza]

Been waiting eagerly for a couple years for a kit to be available - I am in the "needs the portability" demographic. Not too happy with the size of the case, though... I was excited for the idea of essentially a padded filament box that could fit into carry-on without taking up much room, but this looks to be a fair bit larger. With as massive a case as this comes in, I'd imagine you could come up with a slightly modified design based on a more conventional printer to fit in there, and not have the fragility of the glass bed...

[@DiThi]

I don't think it's fair to call the replacement parts "proprietary": Parts like the 90 degree hot end are *already* available for cheap. The most unique part is the heated bed because the whole transparent glass heats up. It's available to buy but in case it wasn't, one can always use the original design of heated stripes for car windows. As for the custom machined CNC parts, you should take a look at the Positron LT project. It replaces all those parts by printed parts and off the shelf parts.

[@thenextlayer]

Wow, didn't know that about Positron LT. It's a minor concern, I admit, but, these parts are more proprietary than, say, a V0.2

[@DiThi]

@@thenextlayer I understand, although I think the hotend is easy enough to make that there will always be a version sold in aliexpress, even though the V3 is still not being sold as a kit yet (so imagine the state when it is). There's also 3 possible beds for sale: the expensive transparent one, the cheaper one with visible conductors (which seem to be sold out at the moment), and the cheapest one which is pretty much like a normal printer bed except flexible with adhesive (to put on a normal piece of glass). I want to make a LT and I will probably get that one while I wait until I can get the clear glass one. I will look at the first layer through a little 5x5 cm mirror I have laying around, or through a webcam.

[@Toni_Toaster]

I don't see any usecase for myself here. I can't say whether such a device will be successful in professional use - only time will tell. I wish them luck 🙂 About PETG: Is it really a good idea to print PETG on glass? It cost me a print bed (when I was still a newbie) ...

[@tim_means_heart]

I've been eyeing it for quite a while and this V3 looks great. I don't think I need one for now as I'm not ready to deal with all the drawbacks (I'd prob buy a used 3d printer in the country I'm staying in if I have too) but this is super promising and I hope they will continue to improve the Positron

[@baddan]

Thanks for the honest review!

[@AtomicBleach]

I want one for my work van lol. Theres lots of times where we don't have a small 1/4 hose fitting or a din rail bracket adapter that a 3d printer would be able to probably make within an hour or two.

Bambu can't suprass 60 deg? i mean, my Ender 3S1 Pro was able to print fine at 70 deg and even 80 deg (tho there are quality drop on bottom side) Sure, on 160mm\s and 10k mm\s accel, but still, seems like i might not need bambu after all, just have to tune and mod my ender Stock Sprite extruder and hotend, taurus cooling duct with dual 5015s

I love the footprint, I don't like the potential mess. I wonder whether it might be easier to detect a failure because of gravity.

[@thenextlayer]

Oh damn, that's a REALLY good idea for a V4... add a pressure sensor to the bed, and if that amount doesn't equal the amount of filament extruded so far... you have a failure of some sort.

[@S_Chand13r]

While I definitely see the merits of doing that. I wonder how logistically feasible that could be. Measuring hundredths of grams, on a constantly moving machine. I’d imagine that the slightest “extra” movement would end up throwing the sensor. Awesome idea, though!

[@juergenausberlin]

@@S_Chand13r @thenextlayer you could average out the reading of the sensor over 10 seconds to eliminate the influence of the moving parts. If the average drops by a significant amount, you have a failure. Another idea would be a light barrier that goes through the printed part. If the light connects to the sensor, you can be sure that you dropped your print. Or what about a simple webcam - a.i. solution that detects an empty print bed by comparing the last state to a screenshot before the print - you probably don't even need a.i., as it might come down to counting similar pixels :-)

Suggestion for maker of this. Running a spegeti cam or a shroud on the belts

[@klave8511]

Not sure about all the use cases but I can’t see you using this little guy without a PC. You may find one at your destination and could the use a browser based CAD program but you backpack is getting heavy when you add the PC and a roll of filament (and a roller base for the filament). For off grid use you need a battery pack. Price is too high, I can’t see the small size being real and if I was clever I’d package an A1, PC, filament and battery pack into the same suitcase as this little guy and I’d be able to print more materials.

[@MarkStinsons]

Given it's designed for portability, it doesn't appear to be using USB-PD. Is that even possible? My portable Pine64 USB-C PD does up to 60watts (5/9/12/20v). Other Laptop adapters are greater, like the new Framework 16 laptop has a 150 and 240 watt brick. Being portable should mean using re-use of your existing portable PSUs -- USB-C PDs. That also means being portable, should have a commonly input power plug & voltage in different regions.

[@m97120]

4:45 Is the hotend really PTFE-lined all the way to the nozzle like an Ender?? Do you know what the reason behind this decision was?

[@sovahc]

Very cool. If the price were a bit lower, I’d easily jump on this as a second printer.

Portable may be the USP but my first thought was easily broken down for storage, so ideal for people living in a small flat with not much free space.

This is an interesting concept, I wouldn't have use to justify the price. I could see this having a market place you did mention veterinarians, I could potentially see farriers also benefiting from this but it would definitely need to be able to print high temperature filaments to be useful for this type of market and the others you mentioned.

[@timhoover1416]

I remember seeing this thing running at MRRF last year. I was intrigued by it then and still find it compelling for the same reasons you mention. For field service work it would be a boon. Personally I don't travel much and never with a 3D printer, so this would not be of interest to me at this time. I also think it needs the ability to print more material selections such as carbon fiber and PETG and possibly ABS or ASA. It would be very easy to have a popup enclosure similar to the camera studio tents that people use.

[@colind6797]

Except "popup camera tents" lack even a FRACTION of the rigidity required for a 3d printer... Not sure how you'd get around that...

[@alannguyen5050]

This was such an interesting video to watch! Cant wait for this upside-down technology to further improve.

[@telhunter1]

Awesome little printer!

[@themacbookgamer]

I'm seriously considering buying this with how much I travel, but also it would be super fun to build.

[@thenextlayer]

Yeah, it's honestly pretty amazing, it could just be your "personal item" on the plane, doesn't even count as a carry on.

[@Enjeenier]

Really thought that project died but fortunately it revived itself

[@thenextlayer]

Clearly!

[@nomadsgalaxy]

Our team (Positron 3D) has had some roadbumps, but we've been working hard to keep it alive as much as we can with such a small team.

[@lylek8933]

Been a long spell since I've seen a new Positron vid. High hopes for this technology. :)

[@TheGuilev]

looks fun to play with it

[@kennicooper6659]

For what I do for a living, This would be great.

[@reprinted3D]

Do I have a use for this? No. Have I been hounding Jason about it (and has he been a good sport about that) for more than a year now? Yes. Will I buy one? Yes. It's just too cool of a printer not to buy one.

[@christianmontagx8461]

Oh my god, LDO made another printer it must be good - But it has a non heated glas bed - Yes. but it's from LDO! - But it prints upside down which will reduce adhesion - Yes. But it's from LDO! - You have to calibrate your printer after "rebuilding" it which cost a lot of time - Yes. But it's from LDO! - It doesn't make much sense to carry your printer throu the world - Yes. But it's from LDO! :)

[@thenextlayer]

The bed is heated. Adhesion is great. Recalibration isn’t always required once you learn to reassemble correctly. You seem to have not been paying much attention!

[@skaltura]

For whom needs portability, this is actually quite cheap

[@cybergnetwork588]

Who in their right mind would bring a 3D printer with them on vacation? 🤣 If yes, I am recommending you book an appointment with a psychologist! 😂

[@thenextlayer]

Clearly, you don't have kids in your extended family... Take the printer with you, print fun toys for the kids, and get them interested in engineering!

[@cybergnetwork588]

@@thenextlayer That is a very good point! I am retracting from my initial comment.

[@themacbookgamer]

This would be a super useful tool for something like a high-tech handyman to go to people's houses and make replacement parts for things in an hour or two instead of having to come back later.

[@thenextlayer]

Wow, yeah, hadn't even thought of that. "OK, you're missing this flange. I'm just gonna set up the printer, then I'll head out to lunch, come back in an hour and a half, and we'll get it installed"

[@johnpekkala6941]

Exactly my thought. Perfect for the repairman! Together with a small laptop for CAD/CAM(slicer) you have a complete mini factory with you in a suitcase to manufacture custom spare parts for say washing machines, refrigerators, smaller plumbing parts ect right at the customers place instead of needing to order spare parts that might be both very expensive and also often very hard to find (cause manufacturers want you to instead throw away the entire thing and buy a new washer/refrigerator ect instead of just replacing that small part that might be broken cause they dont make profit on repairing things).

[@smorrow]

Or a technician touring with a band or something.

[@Viseo3dp]

I would buy one so long as it can print pla,petg and tpu without to many problems as this printer could benefit my work on the road and the hobby part as well like at drone race events when you need extra mounts this is why i included tpu as one of the filiments to print.

[@thenextlayer]

Yep. I didn’t try TPU at all. Maybe in an upcoming YT short I will. I wonder how it’ll behave with the 90 degree angle…

[@slinkytrips]

Given that you would need to travel with it in the Pelican case I would rather see it built directly into the Pelican case, it would certainly cut down on setup time and having to plug everything together.

[@JameTek]

Adorable printer 🥰 but yeah, too expensive. It's got a very niche usage case where the price would be justified. I'd buy one if it was like, a quarter the price.

[@michaelbujaki2462]

11:00 60 degree overhang? That's it? I get 60 degrees on my Prusa Mini and it prints top side up.

[@MullerHasse]

Well, for $700,- I'm out. For that money, there are too many options and portability is just not worth that. I was hoping for a $150,- for a complete DIY kit version.....
