ABS print temp vs strength

[curious aardvark]

I reckon with minimal redesign that part could be printed better.
Picture of it in use would help.

Pet-g - bed temp 60c. print temp, I think around 225-230c
Keep it in the lower range for better layer adhesion.

What did you model that signal in ?
Lot of very low facet columns.
More roundness - higher facets makes for stronger parts.

But without any redesigning. Lay it flat and use a few supports along the sticky out bit.
like this:

Printed in that orientation it would be at least as strong as injection moulded. Probably stronger.

It doesn't need supports on the long oval part, but simplify3d always adds way more support than is actually necessary.
yeat another reason i try never to design anything that needs supports :-)

Also don't forget that both pet-g and pla are much better for soemthing that's subject to sun and weather. Abs is the worst of the three for uv exposure and breakdown.
Pe-g has best chemical resistance and highest glass point.

The only reason I can come up with why fdm printer users still use abs, is that they've never tried the alternatives and believe all the misinformation there is online.
