dc.description.abstract |
This study aims to assess whether ultra-high-molecular-weight polyethylene (UHMWPE)
fibers can be successfully embedded in a polylactic acid (PLA) matrix in a material extrusion 3D
printing (ME3DP) process, despite the apparent thermal incompatibility between the two materials.
The work started with assessing the maximum PLA extrusion temperatures at which UHMWPE fibers
withstand the 3D printing process without melting or severe degradation. After testing various fiber
orientations and extrusion temperatures, it has been found that the maximum extrusion temperature
depends on fiber orientation relative to extrusion pathing and varies between 175 C and 185 C at an
ambient temperature of 25 C. Multiple specimens with embedded strands of UHMWPE fibers have
been 3D printed and following tensile strength tests on the fabricated specimens, it has been found
that adding even a small number of fiber strands laid in the same direction as the load increased
tensile strength by 12% to 23% depending on the raster angle, even when taking into account the
decrease in tensile strength due to reduced performance of the PLA substrate caused by lower
extrusion temperatures. |
