I conducted research on A review on the fused deposition modeling (FDM) 3D printing: Filament processing, materials, and printing parameters to compose this piece:
ABS, or acrylonitrile butadiene styrene, refers to styrene and butadiene-containing polymers. It was introduced in the 1950s as a stricter substitute for styrene-acrylonitrile (SAN) copolymers.
Characterized by its amorphous, glassy, and robust structure. ABS offers high impact resistance, leveraging the rubbery properties of nitrile and the glassy nature of SAN. However, its complex morphology may lead to weaknesses due to varying additive compositions.
ABS and PLA thermoplastics are commonly used in 3D printing for items that do not require a specific material.
To compose this piece, I researched on Fabrication of ABS/Graphene Oxide Composite Filament for Fused Filament Fabrication (FFF) 3D Printing:
ABS (acrylonitrile butadiene styrene) is a key material in the FFF process.
Its amorphous nature minimizes shrinkage during cooling. It contributes to high printing accuracy and dimensional consistency. It is ideal for 3D printing.
Graphene-based materials can enhance the applications of 3D printing. Particularly with ABS in areas such as jigs, prototypes, and automotive parts.
However, there are limited instances of ABS/graphene composites in 3D printing. A notable early success was the implementation of a solution-based technique to 3D print these composites by Wei et al.
Materials and Methods
Preparation of ABS/GO Composite Filament
Solution Mixing
Emphasis is put on factors affecting the melt extrusion process. To ensure high-quality filament for Fused Filament Fabrication (FFF).
Techniques such as solution mixing and dry mixing are utilized to prepare the composites. These are then melt-extruded to achieve an appropriate dispersion of graphene oxide (GO).
The thermal and rheological characteristics are examined to assess the processability of the composites. 3D objects are printed to check the printability of the produced filament.
