Abstract
3D printing is a very popular technology lately because of it is very flexible to fabricate
complex design of product with relatively low cost. 3D printing is additive manufacturing which
fabricate parts by building with melted filament layer by layer. Carbon fiber reinforced polymer is
a strong material with light weight. Carbon fiber composite can be quite costly to fabricate and it
is commonly used in automotive, aerospace and medical field. 3D printed carbon fiber reinforced
polymer (CFRP) is still a very new topic in recent years. In this project, 3D printed carbon fiber
reinforced polylactic acid (CF-PLA) is fabricated by Fused Deposition Modelling (FDM) process.
Effect of heat treatment on tensile strength 3D printed CF-PLA is investigated. 3D printed CF PLA with 95℃ annealing temperature and 90 minutes annealing duration showed highest increase
with 5.8% of tensile strength. The result of flexural test showed aircraft component carbon fiber
composite has much more mechanical strength compared to 3D printed CF-PLA. However, 3D
printed CF-PLA has better ductility which has approximately two times of maximum flexure
extension compared to aircraft component carbon fiber composite. Carbon fiber reinforced with
other polymer such as Acrylonitrile Butadiene Styrene (ABS) and Polyethylene Terephthalate
Glycol (PETG) are suggested for future research to discover more potential in 3D printed carbon
fiber composite.
