Abstract


When assessing parts obtained by means of Fused Deposition Modelling (FDM), we may evaluate them visual or by means of metrology related techniques. The present paper focuses on case study that follows methodology from design to final mesh replica of the 3D-printed part. It gives a specific workflow that highlights the undertaken necessary steps for users to be able to properly evaluate accuracy of scanned data, thus identifying printing faults of 3D-printed part against the CAD design. The presented procedure allows for reproducibility and repeatability. Limitations were observed and explained as counter measures were proposed.
