3D-Printed UAV Can Go From Atoms to Airborne in 24 Hours 77

Posted by timothy from the concept-and-model-in-one dept.
Zothecula (1870348) writes "Because 3D printing allows one-off items to be created quickly and cheaply, it should come as no surprise that the technology has already been used to produce unmanned aerial vehicles, or UAVs. Engineers at the University of Sheffield's Advanced Manufacturing Research Center (AMRC), however, have taken things a step farther. They've made a 3D-printed UAV airframe that's designed to minimize the amount of material needed in its construction, and that can be printed and in the air within a single day."

      They can print copper and silver wire, as well as strontium ferrite magnets. Switching from a linear motor (the 3D printed speaker below) to a rotary motor wouldn't be difficult.

      A PSU ... capacitors, resistors, semiconductors, induction coils, and transistors can all be printed. How good a motor and a PSU you can print and how many different printers it would take to make all of the components are other questions.

        You're delusional. You have no idea if that speaker's performance even comes close to the performance of a dollar store speaker, how much it cost, how long it took to print and what its useful lifespan is.

        And if it takes a specially prepared slurry (presumably made in an old Luddite factory, eh?) to make the magnet, doesn't that kind of defeat the purpose of 3D printing?

        But let's not let that little detail get in the way of a good 3D auto-fellation,eh?

          I have no problems discerning between a proof of concept and a viable commercial device/ viable commercial process. If you wanted to specify the latter, you should have done so in your posed challenge instead of getting snippy later on.

          And printing transistors? That's so far away from anything that's even remotely possible, I'm speechless.

        from the article;

        For the conductor, Kiran used a silver ink. For the magnet, he employed the help of Samanvaya Srivastava, graduate student in chemical and biomolecular engineering, to come up with a viscous blend of strontium ferrite.

        I see no mention of copper.

        Switching from a linear motor (the 3D printed speaker below) to a rotary motor wouldn't be difficult.

        I live statements like this; "since we can do A we can do B because they use a similar principle". A linear motor and a radial motor are drastically different. A linear motor is a magnet inside a coil. A few wraps of conductor will do for the coil. For a radial motor you need many more fine conductors wrapped close together to work. Then there is the issue of bearings which have to be smooth enough to handle a few hundred RPM for a significant period of time. A s

          The posed challenge was "When they can print a motor and power supply", not "when will it make sense to print a motor and power supply". In this case, if you can make a proof of principle speaker, you can make a proof of principle radial motor, neither of which will probably be very practical. One coil, no bearings is enough to make it spin (til the plastic bits melt/wear out).

          • In this case, if you can make a proof of principle speaker, you can make a proof of principle radial motor,

            That is a huge leap and a big assumption with no basis in fact. The coil in a linear motor is very different than a coil in a radial motor. The point is that no one has made a 3D printed radial motor. There is a reason for that.

      How many minutes and $$$ to produce the mold? It's pretty clear that 3d printing is a poor substitute for bulk production processes. It is however a viable option in case you want to quickly produce a single instance of an item (prototyping, or locations where shipping or stocking items is too slow or too expensive). It's also a good option to produce small runs of complex items. One of my clients started using a (industrial-quality) 3d printer to produce highly complex manifolds for pumps. They had tr

        It takes them 24 hours to print the UAV frame on a half-million dollar 3D printer. Apparently with all the support material they took away it used to take 120 hours.

        They've taken a very large, expensive hammer and pounded a square peg into a round hole.

      That said to it always ticks me off when somebody calls my quads or hexes drones. They are NOT drones. Drones [in my mind anyway] are killing/spying machines used by the military. Mine are Multi-Rotors. Hobby level flying bricks that just happen to have cameras on them. And not for spying. So I can watch my flights and see what I did wrong.
