The
continuous carbon fiber-reinforced thermoplastic (CFRTP) printing process has
been used more widely in recent years and is an alternative production method,
especially in sectors such as aviation, automotive, prototyping, medical
applications, and aerospace. Although additive manufacturing reduces the design
limitations and makes it easier to manufacture, it is one of the disadvantages
of this method: it has relatively low thermal and mechanical properties
compared to standard production techniques. Therefore, in this study, printing
parameters such as nozzle temperature, printing speed, layer thickness, and
heated bed temperatures were investigated for fused deposition modeling. In
this regard, a polymer impregnation line based on the melt impregnation
technique was utilized to obtain CFRTP filaments using polylactic acid (PLA)
and 3K carbon fiber. Obtained filaments were then used to print three-point
bending test samples in order to investigate mechanical performance. The test
result showed flexural strength between 108 and 224 MPa and flexural modulus
between 9.67 and 17.69 GPa with a 23% fiber ratio. Results from this study
proclaim that CFRTPs manufactured with this method and optimized printing
parameters have great potential for implementing future production methods.
