Cool stuff! Even just for getting rough references into one's preferred program instead of setting up canvases from photographs and whatnot.

[FilamentStories]

I loved the entire video! How you presented each different tool had me sitting on the edge of my seat, both hoping for an elegant success or a total disaster. So well organized, presented and edited. Looking forward to your next video on this rapidly developing topic! —Courtney

Meshy’s text to 3D generator didn’t work well for me so I tried using Copilot Designer’s text to image first (prompting for a 3d image) and then ran the image through Meshy’s image to 3D generator. That worked pretty well. Well enough for a prototype.

someday researchers will be forced to tackle the much much harder and more interesting problem of producing usable meshes...

[johnpapiewski]

My experience with chatgpt & openSCAD was very similar to yours. After several rounds of corrections, the LLM failed to grasp what I was after, and I ended up writing it from scratch. I tried to be as precise as possible in my descriptions of each geometric part for the LLM, but it didn't get the job done. So it's interesting but not useful. At best, it can rapidly create an almost-correct code that you have to tinker with manually.

I would definitely be interested in follow up videos with the newer models. This would a be a serious space of innovation as the LLM's are more properly trained on such to perform better.

With llm's you should have used follow up prompts, for example "the elements are there but not in the correct position" or "the script generates an error because there is no cone object"

Thank you for all your experimentation and explanations - what an exciting time to be involved with 3D Printing, scanning and AI assistance. Keep up the great work!

[remcoder]

Very well done overview of what's currently possible with AI & 3D printing! This is gold!

Been trying this too, Apps that understand "real world" STL output like OpenSCAD, FreeCAD, Blender are going to be very interesting once AI get integrated properly. I suspect the AI/LLMs are going to be more specialized and perhaps simpler than current LMMs that try to do everything. Makehuman understands the kinematics of body shapes, the AI only needs to modify the variables that are used by Makehuman to deign the body and pose. The Makehuman plugin to Blender does the same. AI with OpenSCAD for robot design will be interesting, I use it for model trains, wheels, motors and gears but robots also use motors n gears....

Interesting video! Small suggestion on your talking head shot. If you put the camera a little higher it will improve the shot. Putting the camera low can make it seem like you're "talking down" to the audience and vise versa. Level or slightly higher than eye level is ideal.

[andrewlongfellow]

Awesome dude! Thank you so much for this. Instant mesh is exactly the kind of thing I was looking for.

[OmniSoundAI]

I've used Luma for making models in a game but always wondered how good they would work for 3d printing might have to try it out.

[crazybird]

These programs are very interesting! I think I'll try Meshy or Luma services in the future.

[davismorehead]

I like the lmm open scad model. Looks like it gave you all the shapes you just need to move them around

[oljobo]

Thank You for a GREAT overview 👍😃. It saved me from doing hours of research.

[wtflolomg]

In the LLM/OpenSCAD tests, you could have revisited the chats and asked them to fix the code by telling them what didn't turn out.

[dondec]

What an Eye Opener!! I have basically designed everything I've printed using a 3D modeler... not a CAD system, simply because I know the modeling software well, and I find "fiddling with the design" far easier. For someone like myself, having AI design things I can't or find difficult, would be a huge help. Thinks like screw threads of different dimensions. Hinges for a desktop box. Interlocking parts & buckles. While we're at it, can it help with tolerance evaluation... ie, create a test print that measures screw thread print tolerances (both screw and screw hole) for my printer (a test setup). I like what' you're doing. Subscribed.

The exponential growth of AI is cool to watch. In 18 months it is going to be an awesome usable tool for 3D printing. Imagine describing the parameters for a bracket or repair part in plaintext and the AI spitting out a usable printable file.

[aronjaeger]

i love ideas like that. if it doesn't work, just try something different or something completely new just for fun
