In this video I document my progress towards building a parallel 3D printing platform that can use multiple printheads to work on a single print. The machine uses a polar printhead arrangement to avoid issues with path planning and collisions. It can also continuously spin in one direction it does not need to repeatedly change directions, reducing wear, and negating the downsides of having a massive bed. With twice as many printheads as an IDEX machine, it should be able to print four times faster than anything else on the market.

The “does he even build robots” people are real quiet right now.
-
i think a big concern is filament cost. The pellets used in injection molding are like 6€ a kg, but one spool of filament cost like 20€+
-
Respect for the build, I realized that 3d printing isn't cost effective after you said 3 kg for a trash can 😅😂

Nathan Builds Robots is the definitive source for quadrupolar high speed printing
-
really putting "builds robots" into the name
-
A closed loop computer vision or LIDAR alignment system is the only real solution I can think of. Maybe you could print a special test print and use a 3D scanner to calibrate it.
-
WOW, this is a whole other level. I recently jumped on the RatRig IDEX wagon and while they have got great control over precision alignment with their visual assisted alignment tool (VAOC) this has so many more degrees of freedom! Exciting to see how far you got this already.
-
Whoa, this is awesome! Nice build!
-
Relative positional accuracy is much easier than absolute positional accuracy. A normal 3D printer has great relative positional accuracy, but can get away with pretty poor absolute positional accuracy.

when i first saw your channel i knew you were a gifted engineer who was gonna bring something meaningful to the space (im sure my earlier comments reflect this assumption). this printer is in a league of it's own. i keep rewinding the video because watching it move is magic. thank you for sharing this with the world.
-
I haven’t watched your channel in a while, I’m glad to see you are doing more than just printer reviews, this was good!
-
I suggest an epoxy granite frame. Not because it's a practical solution, but because it would be entertaining to watch.
-
36 seconds and has a subscription, this man is going straight to the top! this is amazing application of multi-toolhead printing
-
Genius build, man! I hope you have grants/investors for your amazing ideas.
-
it was cool to see and feel these prints IRL at open sauce, it's just so foreign compared to any other FDM prints i'd seen before
-
Wow! I knew you were working on this, but I had no idea you designed and built it yourself. I really like the idea of being able to use one quadrant of the bed and treating it like a 4 head tool changer. It would be just like having 4 printheads on a Prusa XL, but you rotate the bed under each head to get the different material or color. If you can just get independent or switching extruder stepper control, you can already accomplish this. To fix a lot of your alignment issues, you can still use bed probing. Provided your rotating bed is stable enough, you can actually probe the surface with each printhead for compensation values. Anyways, super cool! Look forward to more.
-
Would be cool to explore the complicated topic of using these multiple heads to print different models. Here we see them either making the same model per head or one big symmetrical model divided into 4 quadrants.
-
Incredible work man, stuff like this & ppl like you will make this whole home/ office production thing actually viable for everyday people.
-
That thumbnail looks like atmospheric reentry
-
Amazing idea. I love the whole concept. Definitely has some limitations like you mentioned, but I can see a lot of positive development on these designs in the future. Excellent work!
