Overview

Experimental investigation optimizes mechanical properties in 3D printed carbon fibre reinforced PLA components, enhancing performance.

Key Points

  • To model and optimize the FFF printing process of carbon fibre reinforced polylactic acid for enhanced mechanical properties.
  • Experimental investigation using central composite rotatable design
  • Evaluation of layer thickness, printing speed, infill percentage, and extrusion temperature effects
  • Analysis of variance for significance of parameters
  • Regression analysis for process modeling
  • Desirability analysis for parameter optimization
  • Layer thickness and infill percentage significantly impact ultimate tensile strength
  • Layer thickness and printing speed influence surface roughness
  • Optimized parameters for higher tensile strength and lower surface roughness identified as LT-113 µm, PS-46 mm/s, IF-94%, ET-233°C
  • Carbon fibres demonstrate excellent distribution and interfacial bonding, improving performance
  • Smoother layer transitions enhance both tensile strength and surface characteristics
