You have to print a massive benchy
That was my second thought, my first was along the lines of weird science.
Next time: quadrocopter 3D printer!
part cooling is free :)
Don't think it would be stable enough, maybe a self stabilizing robot arm?
Wow, I've been working on the exact same kind of project for a year and a half! I had so many issues with the design of the anchors system, the way you guys made it is so great I feel I wasted my time ahah! Really great job!
As mentioned in the video, I've added a Hangprinter-specific section to the forums - if you have questions or suggestions, feel free to leave them there!

Wow! Big respect to Torbjørn Ludvigsen! I hope he will success a lot! It's already the great start! This technology after scaling and "upgrading" can be using in house printing! At least you can print it by parts and then connect together. It's already great for making big sculptures for presentations!
Thank you both, I really enjoyed watching these live streams👏👍
I was amazed by the accuracy and the innovation put into the Hangprinter. Great stuff guys. Tough work.
This is the perfect setup for 3D printing a house with a concrete extruder. Set it up with 3 portable aluminum towers, calibrate it, and go. You could scale this to basically whatever size you wanted.
just left almost the same comment before seeing yours ))
At least you did not get thirsty during this build. Lol at the Beer fridge in the background. ;D Anyway, keep up the great work! -Cheers
I like that everything in the background is clearly labeled. Like the Bier trolley.
Thats one large delta printer
Very entertaining, well done!
Great job guys!
Thanks! It was a lot of fun, too!
Well done! an amazing project!
Great editing job, Tom!
Very interesting project .... the sky is the limit!
I love your videos Tom they are the best !!!!!
you guys are very talented well done!!!
Well done, lads.
Haaaaang on. Those nema 23s are just being used as bloody paperweights! I spent way too long trying to find out what they were used for.
I’ve been trying to picture how this would work. I think your approach is very smart.
Wow, great job guys. A lot of work went in there. I think the first one Torbjorn did liked better, with all the electricals below. I'd put the ceiling part under the build platform, place the anchors, and have a simple ceiling relay for the lines. Add some lasers for anchor distance and angles and work on the cal routines. Its a neat idea tho.
this makes me want to build one of these. I wouldn't have any use for it, other than improving and polishing it. i see so much potential in it. since the first time he mentioned possible autocalibation, i have been working on a formula to do it!
Hangprinter (and Hanglaptop)!
#Hanglaptop4Lyfe! :D
Editing Level 2.0 ... I like!
It has to be said the build was both interesting, and entertaining, well done gents :)
I'd seriously look into using an esp-01 as a wifi to serial bridge, there's a fair bit out that and from what i've read it's pretty reliable :)
hi..i like the improvements you made from the first one i saw. i have some idea on a small change that will alow you to print from the base up for some distance before your print tapers
You two look like uncle and nephew doing that great vacation project.
Great project! Thanks so much for the intro and summary videos -- I just wasn't able to dedicate the time to watch all the streams. Seems like a natural to build at MRRF and other 3D printer focused events.
Scale it up get a crane with a concrete pump nozzle
That is an actual thing. 3D printed houses exist 😅
For line viability: run a couple larger visible line from the anchors (back edge - away from rollers) to the the system board (ceiling)
question to prevent filament dragging on floor couldn't you mount the spool on the print frame or would that put too much weight on that frame
Wow, this really blows my mind. $200?! If I had the room for it, I would definitely build one! It would be perfect for such thing as building aftermarket fairing kits for motorcycles which otherwise doesn't have the scale for large volume manufacture.
Cool Beans...

This is a cool project indeed :)
What is the ratio of space required to printable area?
So say you have that 2 meter diameter, you need about 4-5 meters diameter space for the anchor points etc.?
At those distances the low voltages used probably also start to become issue, low voltage DC power transmission over many meters tend to see voltage drop off.
So if moving electronics to anchor, it might make sense to move the stepper drivers still next to the motors with their own PSU, so that the motors get the full voltage & amperage.
Beautiful for Christmastrees - how much pieces are possible per year?
Will it work if the anchor points are raised above the hot end? I.e. attached to walls or on chairs?
Could the anchor points be moved to the ceiling? May be able to make the build volume a standard delta cylinder, rather than a trumpet horn shape.
How did you get a better quality print from a hanging printer than i can with my maker select v2. I can't even get it to print anything larger than a calibration cube.
How long did it take to print the blue Christmas tree? Layer height? What speeds were you using? 1.2mm nozzle, right?
+Eric Randall overnight (so about 12 hours), 0.7mm, around 45mm/s, 1.2mm nozzle
Thank you for the reply and all of your wonderful videos-- enlightening and encouraging!
Hahah, that's pretty cool!!
Is the filament feeding ever a problem? Something like this seems like it would be more susceptible to drag on the filament line. I'm probably thinking too much on it. I can imagine a filament prefeed mechanism based on airsoft autowind mags.
I could imagine boxes of filament wound like networking cable so it doesn't twist or kink. You just set it in place and the printer goes to town. Weight of a spool wouldn't be an issue anymore.
The step motors on the ground are huge. From GitHub I only read hs4401 models. Those seem stronger. Are they different?
When You will do review of a new Prusia MK3 ? I'm quite convinced that You have one already :D
I've been assembling my hangprinter (without Mechaduinos, however), and am wondering if anyone out there has a wiring schematic for a version without the mechaduinos...???? Any help would be greatly appreciated. Thank you in advance
What e3d nozzle should be used for fast prints? Vulcano for 1.75 filament 0.8mm nozzle, or for 3mm filament 1.2mm nozzle..
How could you possibly not mention the hanging laptop? :(
How do you know what the print area is at a given height?
This would be amazing for car part prototyping, you can make an entire dashboard in one go.
Need Rick Sanchez to make the floor 100% level
Jeez you guys look tired! Awesome build, congratulations! But now that I‘ve seen that even the creator struggles with building this, I‘m really scared to build my own....
I'm wondering, would be a mistake to print hangprinter parts in PLA?
A harrier drone for large scale multi drone slicer paths. Connect to power cord with a feed line incompassed
Please pass the drool towel. So very tempted to build this just to say a group of us built it.
Does a inductive sensor work with a 1,5mm aluminium bed
Under $200? Bondtech BMG ~$80, E3D Volcano ~$65, TMC2130 ~$55, Then even the cheapest power supply, RAMPS, Arduino, and 4 steppers motors will add at least $55. Then you need printed parts and all of the other building materials (wood, bearings, cables, hardware, ptfe, etc.). You are at $300 minimum on this project without any tax or shipping and low price estimates.
Logan Brueck you underestimate the power of Aliexpress
this is goddamn cool
If you made it 4 axis.. You wouldn't have the truncated shape at the top problem?
Why not motors on ground and anchors on top?
Did I spot Vim on his laptop? Very nice!
Marcel Robitaille
You would not believe how often I type :wq into notepad when I'm using/fixing other people's computers....
tin2001 I often start searching with / in all kinds of things that aren't Vim.
my house will be printed
But what about the filament? Doesn't even a large spool run out mid-print?
this is where octoprint would come in handy, mount it to the roof
I'd like to a see a version of this that uses empty filament spools instead of printing wire spools.
Hey Thomas, another very interesting thing for this channel would be a visit to "Festo" its a company based in Germany and they build robots and stuff. Also use alot of 3d - printing :p
Ever going to show us how to built a beer dispenser like the one in the back?
I want to ask if the hangprinter has the ability to create supports for more complex models
+katdog wall whatever the slicer generates! It's the same 3D-printer bits, just with a different motion setup.
this was an awesome series but sadly i still dont think i understand how the fishing line is routed and so the kinematics confuses me how does this work?!
from what I understand it works more or less like an inverted delta printer.
if you make one line shorter and the other two longer, it will move towards it and vice-versa, then there's another axis for up and down
So if I have it correct, the three points on the floor are more or less an inverted delta, except with variable length to actuator rather than fixed length but moving point? And the one that’s going up to the ceiling is basically only providing the hanging force?
@@JasperJanssen I'm not 100% sure but from what I got the 3 on the ground only provide x and y, because with only 2 cables, you can do +x and +y but you cant do -x and -y (or only +-x or+-y), by adding an extra one you can make it go back. If the 3 were hanged from the ceiling, they could avoid having to use a 4th axis for z by using gravity to pull it down, but it would be harder to hang 3 spots than 1, plus there may be problems with the extruder not pointing straight down.
It's basically what you said, but the cables can only go one way if there isn't an opposing force, and the 4 th cable is z+, while the other cables and gravity provide z-
Another solution would be to have a spring/elastic band as the 3rd or 4th axis, but using a motor is easier and cheaper.
I like it when you call me the Blue Papa
Throw ya hands up in the air
Smurf it like ya don't care
Rockin' that tucked in shirt like a boss.
SNEAKxxATTACK mmm
would a larger mover allow for larger prints higher?
+Kent Thoresen yes! It would also make the entirely setup more stable.
For version 2: ditch the lines, use a quadcopter.
I would be lazy to run up and down - one OctoPrint miniPC up there with ability to flash the firmware - and you are good to go :) I have it setup like that at home - as my RAMPS is on the opposite side of my enclosure. Works like a charm - one batch command pauses Octo, flashes the firmware and restarts Octo again - voila ;) I even use old MK802II as it was just lying around.
I dont think the flashing was the problem, since it was connected with a long USB Cord.
ihr habt einen Bier-Tresen???... wo muss ich unterschreiben? :D
You have to make more videos aubout dis printer
Awesome idea. Stop trippin ahhh, Paint the line yellow so you can see it!
so what's next? drone printing? (position via 3d cameras, no wires, and filament on-board)
using a gimbal for fine movement, and a camera or agricultural hexacopter or octacopter drone it probably would work.
basically a 5x5x5 3d printer on a drone.
@@satibel Yep. Shaper Origin is a real-world example of such a mechanism for producing fine movement so long as the low-precision motion system can keep the tool within a certain distance of the target. But to get any practical use out of it you'd need a fixed structure to supply power and filament to the drone, else the battery life would be too short for anything bigger than would fit on a typical printer. And to fly for that long, the power consumption would get expensive.
@@dekutree64 though you could use multiple drones for faster printing and recharging some while the others fly.
also, it might work for welded chain structures instead of filament printing.
though a crawler might be better than a *copter for this.
what about using ultrasonic range finding for calibration. i just dont have a clue how too program for that kind of calibration
+Lonny Moore Ultrasonic is not quite accurate enough for this unless you use high-end ones
oh ok there has too be a way too allow the printer too be calibrated accurately
+Lonny Moore yes, Torbjorn is working on it using cameras and image recognition
Hey Thomas, what is this awesome intro music?
Cyanne Edwards did you get an answer?
Bashaar Baker not yet thanks tho
Wait I'll Shazam it
Yolanda J.Ram
Ehhh it's not that song Sry I can't find it
Would a 4 corner instead of 3 gives you more flexibility?
No heated bed tho?!?
underfloor heating ;)
Build some furniture!
It's still not possible to print a new car bumper. Sad
factually inaccurate
Hello Thomas,
is there some other way to contact you ? I have a few question´s regarding a Filament Width Sensor.
Greetings
So next step: mount the extruder + hot end on a drone.
Very interesting, I don't like the new music its to loud.
All I saw was Bier. 🍺
That unmotivated camera switching is terrible.
Edits, edits everywhere! Would you prefer jump-cuts instead of a camera switch?
Yes, less distracting in that high frequency. Or if really needed then do a switch to a camera which maybe shows the printer a while, then back to the persons (same view as before the edit preferably).

Exotic. It makes no sense to declare that this printer is not made for tiny things. In French people say:"Qui peut le plus peut le moins" (I'm not French by the way) which means:"A device or a person who can manage a great design, should manage a much lesser one" or simply "if you can do something complicated, you can do something simple"
I dream to be as smart as this boy! But at 50 y o its too late for me....
+noel le galvic it's never too late for anything!
It's always "too late" if you aren't willing to learn.
Shouldn't of started in the first place would of been good!
I don't like the In- and Outro Music, but the Project is realy cool.
Torbjørn pls make a Video if you build a bigger one thant that. :)
You could build a drone based 3D printer outdoors....but if the drone got away from you then you might get reports of hot bird shit falling from the sky.....
first
Y’all mouth don’t go with the video it’s little delay
does anyone really want a printer like this? big prints means huge print times.. this would turn huge times into outright stupid.
If you scale the nozzle size, layer height, and movement speed, then print time is independent of scale. This is why the Supervolcano hotend exists. IMO the biggest problem is cost of filament. I'd be looking for a way to print with waste plastics.
first one I didn't like sorry
Untuck your T-shirt............
Clearly those are the important issues...
