| Abstract: | A multi-axis approach to additive manufacturing breaks the paradigm of planar 3D printing, enabling support-free printing of overhanging geometry, improved surface finish of oblique surfaces, and controlled mechanical anisotropy. Despite its potential, the widespread adoption of this technology faces hurdles in the domains of software and mechanical design. Adding degrees of freedom necessitates more complex path-planning algorithms and an accurate kinematic system. In order to harness the benefits of multi-axis additive manufacturing and ensure their practical implementation, it is crucial to make this technology accessible to a wider audience, particularly considering the significant contributions and limited resources of citizen-scientists within the 3D printing community. Therefore, this thesis investigates the accessibility of multi-axis additive manufacturing technology through the development and validation of an open-design, self-replicating, low-cost retrofit for consumer-grade desktop 3D printers. To maximize build volume and kinematic accuracy, a 2-axis print-head was designed. Path-planning algorithms were developed and implemented to successfully print sample parts, showcasing the printer's ability to overcome the limitations of conventional printers while avoiding new drawbacks. The surface quality and accuracy of the parts were evaluated in comparison to equivalent parts printed using a typical 3-axis process. |
