  • You’d also have to use the same slicer settings, similar room conditions, make sure that you have the same filament roll (assuming it’s an FDM printer), make sure that nothing hardware wise was tweaked (eg. fixing belt tension), make sure nothing software wise was tweaked (it’s nuts how much difference temp can make), make sure nothing firmware wise was tweaked, and the nozzle cant have had too many prints between the suspicious one and now (or like half of a glow in the dark or carbon fiber filled print).

    Edit: and same print orientation, just turning the part direction in the slicer causes different artifacts, in extreme cases I’ve seen a part facing one way fail, but a quarter turn right or left prints flawlessly.


  • I can change what an individual print line looks like to the naked eye just by something as simple as tweaking temperature or print speed. Good luck getting anything remotely consistent intentionally by clever nozzle machining.

    Also, nozzles are dead simple to make, it’s literally just a large drill bit (1.75mm diameter or so) with a smaller (.05mm to 1mm) drill poking the last bit through. Tip is slightly flattened off and away it goes.

    Also, as someone else said, nozzles are a wear item, it’s like trying to track a car down by the brake pads, or a pencil down by the shape of the lead at the tip, using it changes the characteristics of it.














  • Just got the guy out who put the roof on my house out to see if he could find where a small leak had developed and reattach a piece of flashing. Flashing was easy, he popped a new nail in, I just dont have a ladder that would raeach that area. He couldn’t find anything obvious for the leak though so he just hit all the likely places.
