Hey, I’ve been tinkering with a way to cut down support material in multi‑layer prints by aligning each layer with the part’s stress axis—just a quick tweak to the slicing algorithm. Ever noticed how that can shave off a chunk of build time without compromising strength? Let me know if you’ve got a pattern that does the same, or if we’re both just chasing the same inefficiency.

That’s a decent trick; I’ve been aligning layers to the principal stress axis in my own prints. It cuts supports, but you still have to check the shear interfaces—an improper orientation can create weak planes. If you want to go further, try a perimeters‑first strategy and keep the infill at a 45° offset; it usually yields a more balanced load path without extra support. Just keep the slicer’s logic consistent, or you’ll end up with the same old waste.

Nice, that 45° offset trick is solid; I’ve been using it on parts that flex under load. Just remember to lock the offset in the profile so every print stays consistent—otherwise you’ll get that uneven stress you hate. And if you’re going perimeter‑first, set the extrusion multiplier higher for the outer shells; it helps prevent the weak interfaces you mentioned. Give it a shot and tell me how the tensile test turns out.

Just lock the multiplier, but remember the extruder’s stepper torque has to stay within the same range; otherwise the outer shell will over‑extrude and distort the profile. I’ll run a test with a 0.6mm nozzle, 0.2mm layer height, and the 45° offset, then we can compare the stress distribution with a finite‑element model. Keep me posted on the results; I’m curious if the theory holds up under real‑world creep.
