I need help to design a robotic 3d printer, that can print and assemble another printer.
it can be 1 large bed and a arm, or many small robots that add up to be able to finish the task.
I want to be able to feed a printer filament, and somehow print and wind motors as well as potentially 3d printing a magnet somehow if that is even possible.
bottom line I want a self replicating 3d printer design.
then I need to start printing printers that make giant plastic or glass lenses…
edit: just thought about it - Twisted fishing line muscles + hot and cold could work as motors if we could get them to be fine enough resolution to 3d print with - reducing complexity considerably
THe problem is that about 10-20% of a 3D printer is not printable with current technology. It is, to date, impossible to print a motor (because you cannot print a magnet). It’s also very hard to print a bearing, and even harder to print one that’s any good.
Then there’s the fact that a metal 3D printer tends to be a laser sintering a metal powder, and thus needs to be bigger than the thing it produces. Admittedly, with a bit of clever trickery you can avoid this (assembly after printing), but then you’ll lose accuracy.
Now, it is potentially possible if you are 3d printing iron and have some very clever things going on. You could make a weak magnet by magnetizing it yourself, and you’d have to combine it with a plastic 3D printer to produce the insulation on the windings - perhaps some sort of plastic dip would be better for that though. Then you make a whole bunch of parts, and with a robotic arm that exceeds current levels of dexterity, assemble your new printer.
Estimated Size: >1m
Estimated Mass: >30kg
Estimated Unit Cost: >$10,000
Estimated Development time: > 25 man years (ie 5 people take 5 years, 25 people take 25 years)
Estimated Development cost: > half a million
Estimated Power Draw when operating: > 500W
Now admittedly, we could think smaller. But then accuracy becomes hard and I suspect development time would increase, driving costs up even more.
Visual appearance: a box filled with metal powder, a robot arm on one size and a laser on an XY plotter across the top. A fancy actuator/brush that I can’t remember what it’s called to put on the next layer of metal powder.
You would need live cells to do that first of all.
Second of all, this is stuff that’s probably far off in the future, as we’ve just recently been able to get certain types (like bone) to grow into various shapes for medical purposes (which isn’t even remotely close in complexity to a robot).
How is the robot going to make a metal sintering laser.You could use acid but it needs to make something to store it.And also something to make the acid.Maybe microbes could make the acid.
But you would have snrink a similar machine to that down to a reasonable size for the robot.Which is a substantial task.
Then the robot would have to be able to make every piece.
