Abstract:
Desktop 3D printers have revolutionized how designers and makers prototype and manufacture certain products.
Highly popular fuse deposition modeling (FDM) desktop printers have enabled a shift to low-cost consumer
goods markets, through reduced capital equipment investment and consumable material costs. However, with
this drive to reduce costs, the computer numerical control (CNC) systems implemented in FDM printers are
often compromised by poor accuracy and contouring errors. This condition is most critical as users begin to
use 3D-printed components in load-bearing applications or to perform mechanical functions. Improved methods
of low-cost 3D printer calibration are needed before their open-design potential can be realized in applications,
including 3D-printed orthotics and prosthetics. This paper appliesmethodologies associated with high-precision
CNC machining systems, namely, kinematic error modeling and compensation coupled with standardized test
methods fromISO230-4, such as the ballbar for kinematic and dynamic error measurements, to examine the influence
and feasibility for use on low-cost CNC/3D printing platforms. Recently, the U.S. Food and Drug
Administration’s “Technical considerations for additive manufactured medical devices” highlighted the need to
develop standards specific to additive manufacturing in regulated manufacturing environments. This paper
shows the benefits of themethods describedwithin ISO230-4 for error assessment, alongside applying kinematic
errormodeling and compensation to the popular kinematic configuration of an Ultimaker 3Dprinter. A Renishaw
ballbar QC10 is used to quantify the Ultimaker’s errors and thereby populate the errormodel. Thismethod quantifies
machine errors and populates these in amathematicalmodel of the CNC system. Then, a post-processor can
be used to compensate the printing code. Subsequently, the ballbar is used to demonstrate the dramatic impact of
the error compensation model on the accuracy and contouring of the Ultimaker printer with 58% reduction in
overall circularity error and 90% reduction in squareness error.
