3D Printing with a Robot Arm - Computerphile

With dozens of affordable 3D printers out there, why re-invent the (filament) wheel? Feng Zhou has a plan, to improve the strength of 3D printed objects.

Can we please have another, more in depth video about the mathematics behind it? I'm curious to know how you achieve cross hatching on subsequent double curved surfaces.

Looking forward to see your work appear in cura!

I wish we'd been able to see a close-up of the printer printing for a lot longer.

Loving all the roboticists being featured on your channel! You should cover inverse kinematics using Matlab or something free on Numberphile!

One of those ideas that after seeing it, you wonder why it wasn't invented years ago. Pretty cool!

[fricki]

It would be interesting to compare the speed and accuracy of this 6-axis versus a normal planar cartesian 3D printer. Those additional joints probably also bring more backlash and less stability with them.

"Can we see it do some printing?"
And we don't get to see it.

just when I was getting the hand of conventional FDM....

[christopherweeks]

You can do nonplanar 3D printing with a regular 3D printer, if you have the capabilities to produce a gcode that does. You have to be aware of the size of your print head though, so there is no collision. This six axis arm helps with that

This is very interesting topic.
I immediately thought of this very new Startup in Germany in my area that is working on this at the moment.
It is called FreeD printing.

[PieterPatrick]

It does look like it's printing a little shaky.
When this is a finished product, it will be expensive.
Not for us, simple people.

Conventional 3D printer can do more complex tool paths instead of printing just horizontal layers. The software that converts 3D geometry into G code is a simple slicer but it doesn't need to be.

[LikelyToBeEatenByAGrue]

That's cool. It would have been good to get more on how the program paths a 3d model but maybe that's for part 2. Pls?

[flymypg]

You can also add multi-axis positioning to the printing bed, getting 6 axes above and below, permitting printing in ways that can appear to defy gravity.

BTW, the PLA may be full of moisture: What was coming out the nozzle looked a bit bubbly.

[MegaRad]

This is an awesome child of the ideas of consumer 3d printing and a 6-axis CNC. Super cool!

[sauron]

This is an amazing idea, it's incredible it hasn't been tried commercially yet

[davidcruz]

CS2 called for a robotic arm to print inside any kind of aircraft structure... and no one dare. Search HLFC on Wing,

[zertilus]

When I see technologies like this, I imagine taking this process to the microscopic scale and after mass repetition and optimization we will see extreme other technologies.

[gloverelaxis]

extremely cool, would love to learn more about the challenges of writing this software

[sanches]

I love how he calls peek normal matetial :) i have 2 such robots i have an extruder... but i lack the brains and the time :) very well done!

Hello,

I am currently working on a project that involves 3D printing using a KUKA KR3 R540 robot, a REVO HEMERA XS extruder, and a ramps 1.4 control board. However, I am facing synchronization issues between the robot and the extruder, and I'm not proficient in programming.

I am seeking assistance on how to synchronize the movements of the robot and the extruder in real-time. Can anyone provide guidance or sample code to help me achieve this synchronization? Any relevant information or resources would be greatly appreciated.

Thank you.
