3D printed the ABS plastic parts that go in between the aluminum sides in the boom and stick sandwiches. I also re-did the boom sides in 3mm aluminum, as by mistake I made them 6mm thick the first time, which made me have to add 3mm spacers in many other places.
The ABS parts are printed with 16% infill, except the mounts for the stick and bucket cylinders, which are printed with 25% infill.
The filament used is this one:
-
eSUN ABS 1.75mm Gold
This filament's color isn't really that close to the Caterpillar yellow, but it's the closest that I've found. I know there are companies that do custom colors, like
www.plastic2print.com, but those are quite expensive and have order quantity minimums.
So if anyone of you guys know of a yellow ABS filament that is a closer match to the Caterpillar yellow, I'd very much like to hear about that.
