Hi guys,

I would need some pointers, for my Truggy drive shaft axles, one of the piece keeps breaking…
I’m printing in ABS @230degC, 0.1mm layers

Try a lower temp. You want to extrude as low as possible. The hotter you got the more brittle.

OK i’ll try a few different settings

If possible you may try acetone vapor finishing these parts. They kept breaking for me aswell until i finished every single part like that. The acetone seems to increase the interlayer bonding. You could also try to turn it like 45deg and print with support.

I would recommend a different material. Nylon or PETG would be excellent alternatives.

Nylon can be troublesome to print mainly due to bed adhesion issues.

PETG on the other hand is an absolute joy to print. Taulman Tech-G is my current “go to” filament for anything high strength.

In fact I am currently printing the parts for the Truggy as we speak. I’m using a combination of Taulman Tech-G (PETG) and Taulman Alloy 910 (high strength nylon).

Confirm on this. At least since these drive shafts have very small footprint they are pretty easy to be printed with nylon on glue stick layer
