| Abstract Scope |
The carbon fiber-reinforced plastics can be directly formed from digital data by 3D printing using the thermoplastics filament molding method.
However, structures created using a 3D printer have numerous voids. This re-duces the strength of adhesion between printing paths or layers, resulting in dete-riorated mechanical properties compared to structures molded using conventional molding techniques.
To solve this problem, this study proposes a method of adding a fixed heating roller to the FFF 3D printer and adding a compression process that compresses, thereby suppressing the generation and persistence of voids between printing paths and layers. We call the printer that performs the compaction process be-tween arbitrary layers a layer-wise compaction 3D printer. Using this method, we created bending specimens using continuous carbon fiber aiming to improve the bending properties of the created 3D printed structures. |
