CraftBot XL accuracy and tolerance specifications

Customer:

I’m looking to purchase a 3D printer for production purposes in my company. I found the CraftBot XL on your website and reviewed the specifications regarding z resolution and accuracy in the x and y directions. Can the CraftBot XL actually achieve a tolerance of 0.004 mm in the x and y directions? Can you confirm the accuracy with a measurement certificate of a 3D printed CAD model of a cube 100 x 100 x 100 mm - specifically, if I create a CAD model of a cube 100 x 100 x 100 mm and print it without any changes to the CAD model, will the printer produce a cube measuring 100.004 x 100.004 x 100.002 mm?

kupujem 3D printer za potrebe proizvodnje u svojoj firmi.

na Vašoj internet stranici sam naišao na 3D printer

Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics

Bacio sam oko na specifikacije vezane za z rezoluciju i točnost u x y smjeru.

Da li Vaš 3D printer stvarno može postići toleranciju 0.004 mm u x y smjeru?

Da li Vi možete potvrditi točnost certifikatom izmjere 3D print CAD modela kockice 100 x 100 x 100 mm, tj, ako ja izradim CAD model kockice 100 x 100 x 100 mm, i bez ikakve promjene na CAD modelu, 3D printer meni izradi kockicu 100,004 x 100,004 x 100,002 mm?

The tolerance in this case refers to the tolerance of stepper motor positioning, not the final print. The tolerance of the final print depends on many factors, including:

  • quality (chemical composition) of the plastic used for printing
  • moisture content in the plastic
  • print temperature
  • slicer settings

For this reason, manufacturers do not specify this data. From our experience, the tolerance on the final dimension is +2%.

hvala Vam na upitu!

Tolerancija u ovom slučaju označava toleranciju na pomak stepper motora, nažalost ne konačnog printa. Tolerancija konačnog printa ovisi o jako puno stvari, od kojih su možda najvažnije:

  • kvaliteta (kemijski sastav) plastike kojom printate
  • udio vlage u toj plastici
  • temperatura printa
  • postavkama slicera

Zbog toga ni proizvođači ne navode taj podatak. Iz našeg iskustva, tolerancija na krajnju dimenziju je +2%.
