I've tried to compile all info on the build, parts etc at toms3d.org/hangprinter !
And please excuse the audio in this video - The room we're filming is has a ton of echo that I needed to take care of. Will try to get a bit cleaner audio in the next one!
Does the laptop webcam have the same framerate than the camera further away from you?
Hohohohohoho!!!
+Avamander / Laptop... Webcam? Not sure I follow, but the off-axis Panasonic G7 does have a lower framerate than the main GH5.
Interesting printer. Could have some good architectural applications. Accuracy to the "normal" level is not important at all but large build volumes are.
Hang some fabric sheets to help cut down on the echos
Sooo happy you made this video!!
I've got to get building this new one. Thanks Tom.
Wow that TMC2130 upgrade guide, now this! I really like this kind of technical videos.
Some info I missed in this video: How big or how small can the room be for this build?
I can't wait for that stream tomorrow
I feel more powerful after watching this video! Hahahahaha!
If calibration errors are magnified towards the edges of the build volume, it seems like you could actually take advantage of that during calibration.
Wow, the Hangprinter has evolved significantly since I had the pleasure to speak to Torbjørn and see the Hangprinter print the tower at the FabLab in Umeå!
"He's printing a bench right now".. yea yea, everyone prints benchy as a benchmark for the printer. "No no, he's printing an actual bench.. to sit on" :-) 7:50
Not sure it can print a large flat top surface because the lower guide wires would snag on it, unless perhaps the low anchor points could ride up the walls and keep the cable tension and maintain calibration.
+Andy Lee Robinson to a certain extent, it is limited by how large the mover is. You can print wide or tall, but you can't print wide _and_ tall
I look forward to seeing it in action for real... I guess the print head could extend further downwards from the mover for more head room at the expense of some accuracy as I would guess the mover can rock a little on the cables.
Sounds like this idea could be adapted to print whole houses with concrete using 3 or 4 heavy trucks with towers.
First benchy with an outboard motor .
uhm, re: accuracy vs build height - doesn't Marlin support encoder feedback? You could integrate optical rotary encoders on the line directly which would offset the inaccuracies of the line being wound onto the spools unevenly, also would account for slight inaccuracies with the 3D printed gear/spool combo. Maybe this helps?
This is so AWESOME. Put a rod holder for fishing in benchy please. And a beer holder. And an esky to keep drinks cold....and put wings on it so it fly's too ...put brakes in it in case we arrive too fast...put a bar in it ...with free drinks! Make me Captain ! oh yer. This is the best invention since sliced bread. Large scale printing? print me a house please :) GREAT VIDEO
I wonder if it would be possible to make a version that is entirely roof mounted, and the wires go to the roof instead of to anchors on the floor. Storing it would simply be lifting the extruder carriage entirely to the roof.
I was wondering when you were going to build this Tom!
I am super excited you finally have the time to work on a Hang Printer. I have a Version 2 hanging in my garage that I have been working with on and off for the last six months.
Despite months of calibration measurements, and Marlin rewrites with some input from Tobbjorn, I haven't been able to solve the problem of the strings going slack or too tight over time. I was looking forward to your input on the Hang Printer.
Unfortunately it looks like Tobbjorn and you are moving on to the substantially redesigned Version 3. I like the compact design of the Version 2. Maybe I'll still be able to glean some information in your series to get my Ver. 2 serviceable. Or, after watching, maybe I'll also move on to the Ver. 3.
Strings? As in, actual string? It will change a lot with with moisture content and temperature in the air. If i was building one i'd have an urge to use thin braided steel cable, and you can get very thin and very flexible. Dual-Wire Gantry 3D printer (DW-G) used steel cable, and i was considering building one myself.
It really seems like this would be a great installation in an art gallery, rather better than most.
Is there any discussion on the auto calibration I could join?
Perhaps here: forums.reprap.org/read.php?1,792937
That's a really cool project
And they caled me crazy when i wanted my floor heating to reach 60⁰C! 🤣
Can you use a RAMBO board instead of ramps? In the hangprinter firmware in the boards.h file it has RAMBO but when I set the motherboard to the Rambo board it says unknown board?
you could print on a heated tile floor
Awesome!
Roomscale 3d Printing!
NICE
Can some one make the print hang and fix the extruder?
Omg it’s the guy from the video
Where is this at?
+Thomas Schwarzenberger Hamburg, Germany!
I gues they can barrow some idea from multi copter projects which uses flow control cameras. Basically a laser mouse camera . And as a large scale heated bed. Electrical Floor heaters might be a solution if it's build as several zones.
I almost designed something similar for my university honours project. Instead I’m working on a scanner-printer hybrid for making prosthetic limb design easier.
So cool to see a build series on this though.
I'd be curious if my vernier calibration strips would be of any value to perform final "squaring" calibration ? They were intended to measure XY skew of Cartesian printers, but it could also be used to validate final calibration perhaps much more accurately than measuring:

Echo.....
With that beautiful smile I wasn't able to remember if Torbjorn was in this for the sexiness factor (plus hot accent) or because he invented the Hangprinter! In any case, loved the video, keep up the great work. Really enjoyed the mix of Q&A, project updates, and did I mention the accent? Don't worry Tom, you have a beautiful smile too!
Aaron Starbird calm down lol
Hold on did you say that you need to dedicate a whole 3000mm X 3000mm room to be able to print 400mm XY and 1000mm Z ? I have a machine that can print 450X450 and it only takes up 500x500mm I can see the novelty factor of a machine like this and possibly a very cheap way to print large, I just don't see how this is anything other than a really cool toy or show piece.
Michael Scholtz The z-height will be a function of ceiling height, so it can be very high. Regarding x/y, you generally have better precision in the middle of the build plate, but a well calibrated system can make use of a large build platform. You can also build your hangprinter so that it lives in the ceiling, and only takes minutes to set up when you want to use the room for printing :)
Being able to reel the mover up to the ceiling when not in use is a core feature! Everything else can be easily stowed away when not in use.
The only thing I don't like is the new music :-P Sorry
*blink*
Man. Really need to fix that audio. Extremely distracting and annoying. Not the level of quality I'm used to.
Sorry about that @varukasalt, our lounge is a bit of a fish tank and we're actually surprised by the quality of the audio Tom managed to deliver!
No under floor heating install? 😂
heat floor?!!!
THE FLOOR IS LAVA
This looks like an immensely satisfying project. Looking forward to the rest.
Yes! I've been looking forward to this! Thank you for covering the hang printer tom!
Wow, another video this week? Yay!
Oh, you have no idea what's coming!
Thomas Sanladerer :D
The maslow cnc project (a polargraph like hanging cnc router project) was able to address their problems with inaccuracies at the edges of the build envelope by desinging a gondola that keeps the intersection of the guide lines very close to where the cutting head is. Of course this is easier to do in two dimensions.
The hangprinter is a great project and a wonderful idea! Thanks for sharing it.
Where is the double thumbs up button when you need it?
You are amazing! This is so awesome! looking forward to the future videos!
Wow, this thing is inspiring! Thanks for making the series, Tom!
You won't get the print surface up to 60C this way, but what about using a heat lamp (or two!) to keep part temperature up? I'm thinking a couple of 200-500W lamps clamped such that they point near the base of the model.
Use the approach that xy calibration on the prusa mk2 use, only fix the reference points on a flexible sheet and just roll it up when calibration is done, then use a touch probe to mesh calibrate the bed and voila, accurate and automatic xyz calibration. :D
For these large projects i figure a large nozzle and full metal hotend would be most useable as fine printing would take ages.
It would be interesting to try to hack Vive tracking satellites into the calibration process. Then you only need to calibrate the room to the "controller" position.
C'mon Tom! Breaking the rules of 3D printer design would be using a drone to get rid of any spatial limitations. Bet that some israeli start-ups are working on it...
with this should i print in my bed room and set my bed on fire under a glass sheet for good adhesion? or would tape work? XD
Stumbled into this project a little late, but this is really cool stuff. I wonder if it would be possible to use rails or something so the floor guides can rise along with the print and avoid the limitations on build volume.
I'm not sure if it has been said yet, but what if you used some sort of optical motion capture setup such as mutiple kinect sensors, or ps move service? That way it is not only more precise, but can be precise across a larger xy plane.
I’m thinking for practicality the electronics and motor unit should be either at one of the floor units or between two of them. And then the ceiling anchor can be solely a couple of pulleys.
Did you make an Overwatch reference? You smarmy dog
If it could extrude some kind of expanding foam, it would really shake things up.
That kitchen is beautiful tho. Blue kitchen? Nice.
I'd love to make one of these...but I have inconvenient (but adorable) cats.
Would u think a quadrocopter drone would help to hold that printer in place bzw hold it straight at least
Bump* - anything new happening with these type of printers?
The guy is little pretentious , like a person who will give ted talk
i am pretty sure with an infrared lamp any surface can be heated evenly. maybe even mount it on the hot end
Who thinks Thomas Sandler looks like Samm Sheperd
I would love to see about integrating a GPS
MY BABY!
(overwatch refrence)
how can you do it if u dont have a 3d printer
The sound is not the greatest :(
I'm curious how to increase precision....hmm BLDC servo....I should look at the firmware...why isn't the github link there? You want traffic on your site first don't you? :) okay, I'll allow that.
MOLTEN FILAMEEEENT!!!!!
YES! Finally a Tom Technical video! Looking forward to this series.
Live build 13th December, 13:00 GMT
Love the idea of these hangprinters. Could a set of IR sensors be integrated onto the floating head/mover to do the calibration and keep the calibration during the print (by measuring X and Y to the walls and Z to the floor or ceiling)?
Upscaling the system and hanging from cranes, this could be the technique to 3d print buildings without small size limits. Problems to solve. Concrete tube from above with good preassure; cable elasticity (yes, long steal cables have it); wobbling of the suspenssion towers.
Rui Fernando Caldas it's already been done, Google 3d printed house.
I think it may be a good idea to mount an esp32 with an acceleration sensor. It could help debug accuracy or even eliminate manual calibration.
Cool the hangprinter guy! Its a neat idea, certainly niche, I have enough trouble working on reprap designs. Should be fun to follow this series.
Seriously, This is the beginning to large scale printers that build houses with a concrete/other medium pour from nozzle to build homes :)
Ohhh! -- You recorded the audio in a fish tank! XD -- Awesome video though, looking forward to further ones in the series. :D
can torbjorn please print a turret?
So cool! Good job you guys! Tom: I hope you help them develop the calibration :)
Tom thanks man! This is want to see more of!!
A long measurement like that can only be done precisely with a laser. A tape measure will never work.
KASA tape measures are made for construction where small differences do not matter. 3d printers operate in microns at the smallest level. Even the creator of the machine said it himself, that “incorrect calibration will increase exponentially the further from the orgin.” So if you are off by a 1/16” of an inch which is very easy with a tape measure, where the machine thinks that point is 8 feet across the room is actually much further away from the origin on that axis. Prints will never work like that. Also I have a problem with the whole set up hanging, by opening a door and creating small air turbulence, what is to stop the entire set up from swaying back and forth during a print?? Idk i have very little confidence in this machine.
It made my day you two got together! THANKS!
This project needs laser autocalibration. OR at the very least laser based data input inside a calibration program attache.
+aserta lasers make everything better!
Very cool stuff
thats crazy
yessssss
Print a mega benchi
whats the link to the live view?
thefailingstudent you'll find it on toms3d.org/hangprinter
HYPE!!!!
