New 3D printer makes multi-material robots


This little millipede-like robot
is made of plastic and powered by air. It’s a simple design, but the surprising
thing about it is how it was made. This robot was printed,
using new kind of 3D printer. One that can print objects using
multiple different materials, with a speed and level of detail
that was previously impossible. Conventional 3D printers usually build
up objects in one material, bit by bit. But this printer can deposit two, four,
or even eight different materials from one nozzle. And it can do it at high resolution. Each of these tiny 3D pixels
is about the width of a human hair. To print complex patterns
in a short space of time, the nozzles have to be able to switch
quickly between materials. Very quickly. And it doesn’t end there. The new design can print with
multiple nozzles at the same time. For some projects this makes printing much faster, although at the moment every nozzle
has to be printing the same thing. To demonstrate the benefits of
combining different materials, researchers made this origami sheet which has flexible, folding edges
in between rigid areas. The same principle applies
to this beaker-carrying soft robot. The tubes create a vacuum that crumples
the soft parts of the legs, allowing them to bend and walk. This printer can also deposit a wide variety
of materials: wax, silicon and gelatin inks were all used. And the researchers hope this technology
could be used to print things like flexible electronics,
rechargeable batteries and even materials
containing human cells. For now though, if you need a conical flask
delivered, you know who to call.

  1. If you can do this imagine what could be done if you married it to a human organ printer?! You could be embed electronics inside the tissue of the printed organs made from donor cells from the person you’re implanting the organ into you!! In less than 10 years cyborgs as we imagine them today will be an antique future (like an old 1950s sci-fi), if climate change doesn’t wipe us out first. 🤯

    PLEASE somebody build smart organs! 😳
    Extra points if you use a combination of numeric optimization software and biomimicry for its design. 💻🦋

  2. But we have had multi-nozzle printers for a while now, the only thing special here is the fact that it can switch filament in the same nozzle but i dont really see that as ground breaking. And the resolution of a human hair? (.1mm) Thats not impressive most printers can do that if not better

  3. In a hundred years nobody will have to have a job because 3D printers will be able to print everything you need in life and someday they'll be able to print your steak dinner.

  4. it looks impressive, but you can't mix plastics with this, can you? the melting temperatures are far too different for disparate materials.
    and the nozzles are far too close to make printing multiple things at all useful, but that complaint, at least, is an easy fix.

    edit: it uses silicone and waxes and some kind of epoxy, apparently. it explains the properties of the material coming out, but makes this much less impressive.

  5. And with that, I give you the multi layered chocolate bar printer.😆👌🏼😍
    This is truly astonishing though. Been waiting for this design to come out for years now. This is most definitely a total game changer for the 3-D printing industry.

  6. Well, what about "3-in-1-out mix color 3D printing hotend". Google it, you will be surprised how not new this approach is. To me, that in-nozzle mixing is new approach is false (they state in the video that it is new design https://youtu.be/2WL4b03Tfjg?t=59). Any dual/quadruple 3D printer can print simultaneously with all heads. So that isn't new as well. False statement in the video, no really new technologies in the video, average print quality, how does it get into Nature? Rank of Nature degraded for me.

  7. What really matter (To Me)..

    Can this apply to 1. Food?
    2. Space conditions Construction. More bluntly, Habitats, Ships, Satellite.

  8. multi-material 3D printers is not all that new though.

    that said, i have not seen one that can do it without the use of a sacrificial block to empty the unwanted filliment between switches. (i have not really looked around though)

  9. Now if we could do this with FDM 3D printers like a Prusa i3 or an Anycubic mega… that would both improve print times and reduce waste because you no longer need the wipe block.

  10. Dunno about the channel, but like and comment for algorithm. Need more of this type of innovation, not feature adding from "pro 3dp toobers"

  11. I was wondering when multiple material printers would come out. Inkjet printers often use multiple color ink cartridges so why not 3d printers. The question now is what number of materials is the minimum to convincingly produce desired products such as food and consumer products. The other issue to watch for is scaffolding as whatever is printed must be supported till the printing is completed, we've seen pellets and powder used but most 3d printers requires the object be printed with supporting structures to be removed later. Could ultrasound suspension be used? Could water soluble gel be used? Could ice be used with the object printed at low temperatures then the temperatures raised to drain or vaporize the scaffolding? Could something that is gaseous in adiabatic conditions but solid at low temperatures or high pressures be used? Which of these would work with food, clothes, household products, electronics, tissues and organs?

  12. Here I am still waiting for 3d printer prices to dramatically lower before I can buy my first 3d printer and now we're on like 3rd or 4th generation 3d printers.

  13. Imagine a warehouse full of these things on Mars. You still have to get the raw materials there (or somehow extract them from the environment), but the actual creation could all be done on the planet itself.

  14. Сдаётся мне что только цвет разный у материала, а консистенция и текучесть одинакова.

  15. А чем печать-то идёт? Что за пластик? Объединить куча сопел печатающих "каким-то материалом" – это не достижение разума. Вопрос в материале печати.
