A study on the dimensional accuracy of a Qidi Tech X-Max 3d printer

Emanuel Paquete Correia
Abstract:
The world is filled with 3d printers and materials, allowing people to fulfil the fruits of their creative minds. However, certain projects require the production of objects within tight tolerances, and this can be a challenge for the majority of 3d printers. This paper aims to present a study on the dimensional accuracy and precision of a Qidi Tech X-Max 3d printer, by manufacture of three perforated plastic plates, equivalent to test sieve perforated metal plates, and measurement of these parts on an optical CMM, using a VBA program for calibration according to ISO 3310. This procedure makes it possible to calculate parameters at specific three-dimensional coordinates in the perforated plastic plate, allowing an exact characterization of the printing process. The hotbed surface height will be analysed as these printers are known for having warp issues that could be affecting the accuracy of the X and Y axes. The experimentation process yielded an original method for mechanical leveling of the hotbed.
