Precise printing

[Lippsson 0]

Hello Guys! 

 

A question i have since some month regarding printing objects so that they fit perfect into each other. In my CAD drawings i draw without space between my separate parts, but then i want to print, i have to adjust around 0.4-0,6mm space between, so that they fit into each other, like on my screenshot. In my mind, there should be a way where I can import the whole model and the slicer program recognizes the individual parts and renders them accordingly, so that I can then print out one part after the other. So far I haven't found such a solution. How are you doing?

Thank you for your answers!

warm regards

The problem is not that Cura thinks that the two models are one, but they "melt together" while printing. Printers are not infinitely precise, like your models can be.

 

You can adjust the "Horizontal Expansion" setting to have Cura print the models with slightly more room between them, so they don't melt together as much. Also check out and experiment with the "Slicing Tolerance" setting.

This can be done by tweaking with the horizontal expansion,

FI on my S5  with PLA i use a horizontal expansion of -0.03 but with ABS its closer to -0.02.

Best way to test is to make cubes of 10mm precise and tweak the expansion until the print is exact 10mm.
