The performance assessment of additive manufacturing (AM) printers is still a challenge since no dedicated standard exists.This paper proposes a systematic method read more for evaluating the dimensional and geometrical performance of such machines using the concept of machine performance.The method was applied to an Ultimaker 2+ printer producing parts with polylactic acid (PLA).The X catherine lansfield ombre rainbow clouds eyelet curtains and Y axes of the printer were the most performant and led to narrower potential and real tolerance intervals than the Z axis.The proposed systematic framework can be used to assess the performance of any material extrusion printer and its achievable tolerance intervals.
