On Investigation of Dimensional Deviation for Hybrid Composite Matrix of PLA
- 4 Downloads
This paper deals with the investigations for controlling dimensional deviations of 3D printed thermoplastic composite matrix-based prototypes with fused deposition modelling (FDM). The dimensional deviation results suggested that infill density 60%, infill angle 45° and infill speed of 70 mm/s are the optimized printing condition, but only infill density is the significant parameter in the present investigation. Surface hardness analysis supported the observed trend for dimensional deviation. It has been observed that the 3D printed prototype held very low electrical conductivity (<10−6 S/cm) and was suitable for structural engineering applications.
