I can think of a practical purpose: more extuders without taking any more space. I could see this machine being the same size with 20+ extruders. Multi material, color, etc. and to add more you only have to add another extruder and plug its location in. The material change is as simple as changing which extruder you use and giving the center axis a little turn. There may be better ways to do this but this setup definitely has its purposes.
why - i’m fascinated by this and its compact features explained above (hopefully you can adjust it so it maintains a “documented and reliable travel speed”) *standard speed
This is a most curious design, and has some characteristics that could be useful, should you want more than 2 materials/colors. Definitely a different take on a bed-flinger!
hello nozzleboss, you are a genius and your code is awesome! I came here from the hackaday page on your dual polar printers. I think the beast of a setup (5 x direct drive diamon hotend) has too little screentime. I think this monstrosity deserves to get more attention. I played around with your blender plugin and I love it! this is really useful and a nice concept of working with gcode. You deserve the name nozzleboss!
Thank you. Let me know if you have some use for the nozzleboss addon...Yes 5er direct drive...still on my mind. Maybe one day there is a push for smaller filament diameter like 0.7mm. Would allow for very small extruders, but not sure how many other problems you run into with that...For now the bowden version is easier to handle.
I remember reading an article about someone trying to make a milling machine using two polar motion systems, he found that work area and price being equal that heavy duty wheel bearings torques properly resulted in a more rigid setup than using linear rails, wondering how that translates to stability and accuracy in 3d printing.
Theoretically I'm pretty sure you could have as many extruders as you can fit around the circumference of the circle made be the two shown here. Although with them all being that close it may be a good idea if they could be slightly raised and lowered independently to avoid unintentionally rubbing the print
This is really cool! Can it be loaded with 4 different filaments and do a single 4-material print, passing the workpiece back and forth between whatever printhead is needed next?
Absolutly love it! reminds me of a pottry wheel a bit. Seems like it would be possible to add another outer table in on the other side so both extruders could be run in a mirrored way? Not sure if this neccessarily makes the concept more practical 😅
@@levetbyck Not sure if you don't know about bed leveling in 3d printing but if not most all 3d printers require leveling the print surface to make sure when the nozzle tries to lay down filament it is not too far or close from the bed. Very small bed level variations can cause all sorts of problems like bad adhesion to the plate causing your print to come of the plate mid print
Maybe one of solution is to have few hotends on one rail but with different motors/belt? Only one need is to fit >=2 hotends and have spare space on both sides of rail. This should be feasible also on standard 3d printer (I mean XYZ not crazy like this)
Nothing ready to use I'm afraid. The cartesian to bipolar conversion is based on an existing bipolar Marlin fork, though. So should be possible without too much work. The project page has some more info. hackaday.io/project/177633-dual-disc-polar-printer
The gear ratio (20:1) compensates for that. (diameter of bed*pi)/(microsteps/rev)*(gearratio) = 0,00625mm/step on a 130mm bed That's 2 times higher resolution (not that it matters much) than most 20 teeth GT2 pulley setups. And that's on the outer parts of bed, center is infinitely more precise. ;)

Totally impratical, but super cool! The kind of machine that makes you want to make one for the sole purpose of having it.
Me too! I like making printers so I'm totally tempted but alas I have a ender to switchwire conversion project already ongoing

Maybe you have a print that is multi colored
@@henrydonaldson4665 for multi color (16bit) :-) or gray scale. Now we have the solution, lets look for a problem.
Really nice job. Love the creativity with this.

I love the stablility of this design compared to a normal scara.
think of how both “bearings/gears” has to rotate simultaneously to make a straight line..
- mind blowing
Now that is a bed slinger!

The sound that it made when x-axis rotate is satisfying!
clearly you dont own a 3d printer
@@moltenhydrogen2218 Actually, I do...and I made it myself and it works:) I just don't know what that rotating thing called
you could probably stack alot of extruder heads on such a design for multimaterial/color prints
absolutely brilliant

@@GrandNebSmada i think 3 or 4 would be a good number for that, depending on the size of the print/build plate
now this, this is why mankind is worth saving
Multiple build plates and two or three more nozzles for color change would be amazing. great job!
what an interesting idea, in the near future will look how to make something similar
You could totally make this thing quad extrusion, possibly more with some clever planning.
Or even hexa
What an interesting idea...
Very interesting
My mind is blown! I want one!
The g-code be like ↩🔄↩
Really cool design
cool design!
Why does it need a purge block if it's using two separate extruders?
AWESOME.
That's super cool!
Now that is awesome!
This is so cool
Is this DIY? I Love it!
This is really cool! Can it be loaded with 4 different filaments and do a single 4-material print, passing the workpiece back and forth between whatever printhead is needed next?
nice footage (never thought versions like this existed)
Interesting consept 🤔👍
amazing
BECAUSE I CAN. :)

yeah (just like pottery!)
really cool! can only imagine how difficult it would be to level the bed though
level the bedding? because it isn’t exactly supported enough at the far side of the pylon
*pylon/middle section that holds the extruder..

Nice concept. Hope to see more from that. What firmware do you use? I guess there is no ready-to-use profile for these cinematics?

Serious custome code right there
Wild!
woah
Nice project! How did you slice an object for this kind of printer?
Dude what the duck is this kinematics? This is impressive af
Muito bom!
woow supper idea you can make more robust and different conductivity structures !
Wow 👏, 😎👍💪
What are the benefits of this?
Is this built on the frame of a monoprice maker select mini?
Bro are you from the future?
😍 😍 😍
Hi, how fast can you make this printer go?
👏🏻👏🏻😃
Bro I was wondering about this machanism. Insanely cool bro.
Whaaaat in the worlllld?
How complicated can i make a 3d printer: yessss!! But very nice that it worked.
You can print in 2 materials or colors super cool! But hella impractical a 2 hour print would take 5-10 hours most likely 🤣
I'm sorry... what? And also YeS
кааааак он ЭТО делает?!
this is a great example of what we call overengineering, but looks cool
You should make one side a Cnc thing or laser engraver.
cool but what for?
Actually, it's changing nozzle.
cool design 👍BUT not to fast I'm afraid.
The downside of this printer is that you have a much smaller resolution on the outskirts of the bed than in the middle.
The gear ratio (20:1) compensates for that.
(diameter of bed*pi)/(microsteps/rev)*(gearratio) = 0,00625mm/step on a 130mm bed
That's 2 times higher resolution (not that it matters much) than most 20 teeth GT2 pulley setups.
And that's on the outer parts of bed, center is infinitely more precise. ;)
