Hi everyone, I've been using my Ultimaker 2+ for some designs with tolerances that I thought should be within the printers capabilities.

To test the accuracy of my setup I decided to print a 4x50x10mm box and lay it in different orientations. See attached picture.

Once printed I measured the dimensions with a caliper and always found that they're consistently about 0.1mm larger. Especially in the 4mm dimension.

Any ideas?

I've tried both Cura versions and simplify 3D with similar results. So I'm leaning towards a hardware/firmware problem.

I'm printing with the 0.4mm nozzle using the default Fast settings in Cura using PLA. 5a331df3b063d_ScreenShot2016-06-07at5_53_48PM.png.5bad32acce6e51c9535bd8da5aba8242.png

You also have to take into account the material expansion/retraction, when it cools the material retracts.

if it's a bit larger then maybe you are printing to hot causing over-extrusion? What are your print settings?

As @DidierKlein mentions, the key here may very well be in your slicer settings.

Move out of the comfort of the preset profiles and into the advanced and expert domain (these are Cura menus), measure your filament diameter and get to know your printer, then you can and will get closer to your goal :)

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
