@branbepic We only use PLA for something like this

IOW things that hang on the wall
This too has been printed on the Chiron too. All of our prints are done with a Volcano Clone and a .8 nozzle
The gears inside the wheel are Nyon 910 from taulman the Tire is TPU from Zyltech the rest curently is Zyltech ABS.
Here we Acetone welded it together

We are building a robot that will be 26 in dia octagonal on the bottom and 5 ft tall. All prints are solid pieces of plastic The frame has almost 9kg of ABS in it . The white stuff is styrofoam covered in bugscreen and paint to make a good base for some 8 an 10 oz fiberglass and probably some woven roving in places The gearbox and wheels will drive it. I got some kids working on the head that will be semi translucent PETG and look something like the logo above (hopefully) and others work on things like pylleyse

And other brackets and mounts. And 3 more gearboxes. at least . the whole machine should weigh 80-100 lb when done
