Abstract Scope |
A multi-axis extrusion-based 3D printer was developed with two printheads configured orthogonally, adding counter-gravity printing capability. Process settings, including layer height and print speed, could be customized for each printhead. Printheads could be controlled independently to manufacture products with customized spatial properties. The CAD models of products were sliced into at least two segments to prevent collision between printheads and designs. The primary printhead needed to start to create a part of the design as a substrate for the secondary printhead, which stated its action when enough space was provided for its motion. Subsequently, the primary printhead could continue constructing on a part built by the secondary printhead.
The printheads were utilized to manufacture three-point bending samples comprising two longitudinal segments bonded in their thickness direction. The results showed that the segment configuration with respect to the loading direction can significantly influence flexural strength and crack initiation. |
