Uncertainty of Ultimaker 3

[pkmaglev 0]

I'm new to 3d printing and want to make a couple of parts that can slide into each other's grooves. I was wondering what the uncertainty of the Ultimaker 3 is in the x, y and z based on expierence or if there's a source that says that.

I don't think theres any way to put an exact number on how accurate it is, there are too many variables. Its pretty safe to say the Ultimakers can easily make parts accurate enough to fit together but its going to take a little practice and trial-and-error to make everything work consistently.

While you can change print settings to acheive better precision, usualy a 0,2mm gap is required between mating parts to being able to assemble them when printing on a UM printers (My experience is on UMS3 and UMS5).

 

You can get better precision with other printer brands (0,02mm on Prusa I3Mk3 and 0,00 on Bambu lab X1C)
