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 👌👌
Thanks
Wow! Great comment! I will try the Bambu heater fix!!! I’m also gonna pin this comment!!
@@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)
didn't slice or e3d come up with a positron specific hotend?
Phaetus. Not released yet though.@@42436freak
OMG you got a Positron! I've been wanting to build one of those since seeing it a year or so ago. Looks wild!
It's pretty awesome! Talk to you in an hour bud :)
Yes, as talked on ERRF, will get one to you when production coming! ❤
I'll take one too
Build a voron
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.
Man, this is going to be a first aid kit for emergencies around the world. 3D printing and fixing on the spot, cool.
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.
I had you in mind!!
@@thenextlayer Aww shucks, thanks!
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.
I've been following this project since the start! I can't wait to see the production model!
I just hope its not a bank breaker
For anyone interested - I'm the Project Manager of the Positron Project, I'm happy to answer any questions that anyone may have.
What is the final power supply specs? Voltage / current? Thanks!
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?
There’s so much cool innovation in this machine. If not individually, then together in this configuration. Super cool.
Glad to see others posting about Positron builds 🤝Excited to see the project continue to get traction!
One time I brought my WizMaker P1 on an airplane in my suitcase, but yeah this one takes it to a new level
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.
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.
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
Better subscribe soon the 100k giveaway is next week..:: jle.vi/100k
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.
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.
But is that a side benefit or is that the true world-changing bit?
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 ❤
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!
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.
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.
Thanks for the feedback. I’ll keep it up
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.
I like the way you present your videos, very easy to understand and follow.
Really enjoy your videos!
Thank you very much!
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
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.
Great review, Bro))) I've been watching this project almost from the very beginning))) It's nice to see when someone's ambitious idea becomes a real, and most importantly an original product)))
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.
Thanks for the kind words. Maybe, but it works fine at 210!
@@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.
@@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)))
I saw the inital video from Kralyn some odd years ago. And I am sooo happy to finally see it in production! :D
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. Also several of our instruments that we have ordered Ive noticed they are now using 3d printed backplanes lol.
I'm so glad this printer made it through to the product phase!
Thanks for the honest review!
I've been following the Positron for a while, but not too closely, and it's come so far in just a year!
What a cool little printer! I just wanted to ask if you were planning to make a video about your mmu setup with autowinding filament holder😊
Maybe. ERcF 2 came out and now I don’t really wanna do a video on the old version.
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.
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.
I have high hopes for this. Been following the positron for years and but i likely can't get it until it can handle higher temps.
I need functional parts. I live in a van and i need to do ASA and PETG. I'll build a mini enclosure for it.
So i am heart broken i can't just buy a kit when it comes out because it can't do what i want it to.
For ABL there is a Microprobe, that fits perfectly in the printhead.
I'm very excited about version five or six! Not quite there yet😅
As soon as this is available for purchasing Im gonna get it i hope I can successfully print the plastic parts on my Ender3 powered by klipper
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)
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'.
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.
Bingo!
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.
Honestly... his design was great even before LDO and ive been watching this for a while....im super supportive of his idea and glad to see its working out!
When will they release this kit? or will we be able to preorder anytime soon?
A few months max.
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
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...
I probably wouldn't get one of these, but I appreciate the portability aspect of it whilst trying to maintain a level of quality
Whats your filament rack solution? I tried looking for a video about it but haven't seen one!
Reprack! I’ve done a few vids :)
@@thenextlayer ah. Thanks! Your discord responded too. It was the front bars that threw me off but I think it's the rewind system. Thank you, love your vids

Positron General Manager Here - Thank you for reviewing the kit! We really appreciate it! :D
Did you mean to end the video that way or did you forget you have a new outro graphic with audio. 😂 ❤️
I’ve wanted one of these since it was first announced. I plan to be an English teacher though so I doubt I’ll have much need to move it around. Will I still buy it to carry to the school I’ll work at? Yes.
wait, i'm at overhang part and... 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
Pretty sure he's talking without drop in quality. Almost any printer can do any overhang but where it falls off is diff for each
Seems lots of changes from its first video. Really out of the box idea 👍even it can fit in a box.
This is cool for school or small projects parts. I still think FDM is still slow to print on the go. Still waiting for FDM speed to print like a laser printer and really plug & play.
Respect this designer out the box ideas.👍.
Thanks for sharing and making something different ❤
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?
Speed
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.
Except "popup camera tents" lack even a FRACTION of the rigidity required for a 3d printer... Not sure how you'd get around that...
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.
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.
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.
But it would make more sense for the Military and emergency relief sectors.@@thenextlayer
Suggestion for maker of this. Running a spegeti cam or a shroud on the belts
they might be able to prevent the stuff dropping into the gantry belt area by just using some magnets and a springsteel plate as a cover for that area.
Reminds me of a walkman cassette player that Sony made that was designed to be no bigger than a cassette box.
I have been printing finger splints on demand sized to person which is quite a useful usecase
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) ...
I'm seriously considering buying this with how much I travel, but also it would be super fun to build.
Yeah, it's honestly pretty amazing, it could just be your "personal item" on the plane, doesn't even count as a carry on.
A big big positive Factor would be, if LDO could make it work with accus from f.e. Bosch, DeWalt, Makita etc.(with adapters maybe).
thats a manageable mod
@@wombat8980 unfortunately im no electrician 😉😁😕
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.
Is this version based on the Positron LT?
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
@@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 need to build one!!!
Were can we buy the kit
In the future
Very cool. If the price were a bit lower, I’d easily jump on this as a second printer.
Been a long spell since I've seen a new Positron vid. High hopes for this technology. :)
It’s in the perfect colors. 😍
This was such an interesting video to watch! Cant wait for this upside-down technology to further improve.
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.
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.
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!
@@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 :-)
Dude! This is so cool!
As the Positron V3 owner: if you like it, buy it. It’s print fine 😺
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.
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…
Woah looks like I found my next printer
if you do end up taking this with you on flights, expect to wait an additional 2 hours while TSA looks through your device to make sure it's not a bomb.
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
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.
Great idea. But you still need Filament, so why not putting 3-5 packs of filament in a carbon x1, make the frame real sturdy and take that to were you need it... as said, the idea is great, I like it
Use? No, but the innovation of it I can get behind. Your scenarios of use were spot on. Hope for the success of it!
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.
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
@@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.
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.
I like you even more bro!! I'm still here printing 😊 am Israel chai
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.
looks fun to play with it
For what I do for a living, This would be great.
really love this but do not have any need to have a printer for travel. plus a v0 is more suited for tinkering (enclosed chamber, compatibility over multiple toolhead, hotend, and extruders)
I can certainly appreciate the R&D and custom parts that went into this but $700 is too steep. I feel like at $500 it would still be expensive but at least justifiably so.
Maybe with time the prices can come down. Hope so.
I built one myself for $550 and a month of work…
Wow so interesting. I'm excited. I saw Kraylyns video right when it came out and he kinda disappeared. I did know ldo had it in the works and it's cool people will be able to get one soon
Yeah I wonder where that guy went. I heard from one of his team members yesterday so there are still people developing it.
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.
Soon you can!!!
Awesome little printer!
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.
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.
wtf I was just thinking about a design like this the other night lol
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.
Wouldn’t mind a pocket printer 🤘🏽😆♥️
Really thought that project died but fortunately it revived itself
Clearly!
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.
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.
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"
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).
Or a technician touring with a band or something.
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.
a portable 3d printer.....soo your saying my Voron 2.4 350 isn't portable? LOL.
I actually DO travel with my 2.4 350, to Model Train Shows (those handles are very good to have on top) and it always something entertaining for people to see. Coupled with its size, you usually can see it from anywhere, big Red printer is kinda hard to miss. Selling buildings and some rolling stock I make with it.
Still the 3d printer in a box is a cool idea, if it could be made cheap enough it could be a good starter too. There are other printers out there that are sub $100 that are....questionable at best, and only print PLA. However they do, actually, work to introduce people to printing in a very cheap way.
Sales pitch?
