Mono and multi-response optimization of 3D printer parameters to attain improved hardness and surface roughness

Abstract

3D printing refers to process used to create a 3D object in which the material is joined or solidified with materials being added together. 3D printing Prototyping and tooling to direct part manufacturing in industrial sectors such as architectural, medical, dental, aerospace, automotive, furniture and jewellery are the potential applications of the additive manufacturing. This study describes certain aspects that must be controlled in and around an entry-level rapid prototyping 3-dimensional technology platform to investigate printing quality and optimization of the process. PLA (Poly Lactic Acid) material is to be used for making components. Printing speed, Layer thickness and Fill density are selected as 3D printing process parameters whereas component hardness and surface roughness are selected as responses. L9 layout is too followed for experimentation. Taguchi method is to be employed for the optimisation. Result of the study shows that, the longer thickness and printing speed are most influential parameters in developing surface roughness and component hardness respectively.
