Manufacturing parts accuracy evaluation of using 3D printing technology

The accuracy of a 3D printer was analyzed in accordance with ISO 230-2:2005. This standard provides norms and guidelines for testing, including the evaluation of the accuracy and repeatability of 3D printer axis positioning through direct incremental measurements of individual axes. The testing methods are applicable to both linear and rotational axes. These tests can be used for typical, acceptance, comparative, periodic accuracy confirmations, and accuracy adjustments of the 3D printer, among other purposes. The testing methodology involves repeated measurements at each position. Based on the conducted analysis, the relevant testing parameters were determined and calculated, with their errors assessed in accordance with ISO/TR 230-9. Parts were manufactured on a custom-developed 3D printer using the Tevo Tarantula model as a baseline. Subsequent control of the geometric dimensions of these parts allowed for an evaluation of the accuracy of products produced using 3D printing technology.
