What did you 3D print today?

Maybe enable z hop for supports and print the supports at a slightly slower speed -10%+- so if it does collide with the nozzle tip it doesn't snap the support trees.

 

Question for you experts.

I've been throwing around some designs for a 3D printable intake plenum and manifold. Think a 3-4 piece design that bolts into the factory intake manifold of a 5VZ-FE.

Temperature-wise, I'm not sure if I 100% need to make the entire thing out of PA6-GF, or if I can get away with PET-CF at half the price. Any of my designs will seemingly take around 2kg of filament, so PET-CF would be the price point closer to reality. Do I risk it? Or do I just make sure the areas contacting metal are PA6 and let anything with radiant heat be PET?

Keep in mind the inside will be constantly flowing air that's gone through an intercooler, so the inside will be under 150*F, but the outside will likely see above radiator temps in some locations (230*F/110*C). PET-CF is supposedly good above 140C and PA6-GF above 180C. Mainly I'm worried about hot spots I can't predict.



In unrelated news, I have an Ender 3 S1 for sale

 

My spool of ABS-GF was $26 (1kg). It's relatively cheap and will have better warp resistance than PETG. It's only downside is that it's also going to be the least flexible of the filaments.

 

PETG and even ABS/ASA heat deflection temps are too weak to be considered here. This is PET

 

My mistake. I did not realize that there was a glycol-free version of polyethylene thppthrth out there.
