3D printed movable parts

Recommended Posts

Posted · 3D printed movable parts

Hello makers;

I found a bearing in thingiverse that is supposed to be made in one single print, so when I tried to print it with my very recently bought Ultimaker 2+, the parts just fused together, and I wasn't able to have any movement inside the bearing. So I wanted to ask if any of you tried printing parts that are movable together in one print with an Ultimaker 2+ ? Did you succed ? and if you did, what are the settings that you used ?

You should be aware that models found on Thingiverse or any other platform are usually not made to be printable on every printer. So the designer (hopefully) printed the part on his printer and therefore the model has the tolerances and clearances for this specific printer. That being said, not all models you find on such platforms are working or not working with your printer.

 

But, you can do some adjustments to get better results:

  • print slow 30-40mm/s
  • equalize all speeds (inner, outer wall, infill, ....)
  • print as cold as possible
  • avoid the elephant foot (bed leveling or negative initial horizontal expansion)
  • set slicing tolerance to exclusive

And in worst cases you can play with horizontal expansion (negative value)

 

But again, even if you take all this settings into account, I it is possible that this specific model is not working. Read also the comments from other users or check the makes, to see if others were possible to print it. I usually don't print models without comments and prints from other users.
