Method & Evidence

AimHow can response surface models be utilized to optimize process settings for large-scale additive manufacturing with natural biocomposites, considering tensile strength, shrinkage, and dimensional accuracy?
MethodExperimental Design and Response Surface Modelling
ProcedureFace-centered central composite designed experiments were conducted to collect data on the relationship between process settings and the geometric and physical properties of extruded biocomposite filaments. Response surface models were developed from this data, and multi-objective optimization was applied to predict optimal process settings. Toolpath parameters were then identified, and a shrinkage model was developed and scaled for toolpath compensation.
