| Abstract Scope |
Advancements in desktop material extrusion (MEX) printers have led to an increasing support in multi-material fabrication, enabling end-use parts that leverage the distinct properties of multiple polymers. These newly added capabilities have expanded the toolbox for which designers can leverage in the designs they create for additive manufacturing (AM), however, the interfacial bond strength between dissimilar materials remains a critical limiting factor in structural applications. This work evaluates the tensile strength properties of multi-material objects manufactured with desktop AM. The default settings from PrusaSlicer were treated as the control in the experimental tests. The interlocking parameters were then modified by directly editing the G-code beyond the constraints of PrusaSlicer’s native interface. The results of tensile testing these new samples demonstrated significant improvements in the interfacial strength compared to the default settings, validating this new interlocking pattern for high-strength applications. |
