In terms of building intricate features or complex parts, consumer 3D Printers have their limitations due to overall lower resolution and accuracy. This paper deals with the development, manufacture and testing of a benchmarking model, that can help evaluate the dimensional accuracy of 3D printers. The aim of this being to test the 3D printed model against a real-world product equivalent, that is universally recognised and accessible – a LEGO® brick – using its interlocking function as a test with an entertaining element. The methodology is demonstrated with a case study based on a Material Extrusion 3D Printer with measurements determined by a Coordinate Measure Machine to ensure high accuracy readings of the benchmarking model and the real-world product equivalent it is to be tested against.
