| Abstract Scope |
Printing tall thin-walled structures with good mechanical properties and geometric accuracy using Fused Filament Fabrication (FFF) technique has been challenging due to weak layer-to-layer bonding. In this work, a previously demonstrated concept of providing additional thermal energy during printing is utilized to print relatively taller and larger structures compared to standard tensile test specimens. A three-point bend test is carried out on a Polylactic Acid (PLA) structure representative of functional parts printed using this technique. In addition, geometrical deviation and surface roughness are evaluated using a Faro Arm scanner and a Mitutoyo SJ210 profilometer, respectively. Results demonstrate that providing additional in-situ thermal energy more than doubles the bending strength while maintaining or exceeding geometrical accuracy and surface finish, compared to a standard specimen. These results demonstrate the potential for printing effective thin-walled components using this technique in order to meet practical strength requirements in a variety of applications. |
