Investigation on optimal parameter combinations for 3d printed nylon af80 using various techniques

Abstract

Additive Manufacturing (AM) techniques are novel methods which can transform digital model in to tangible solid objects by adding successive layers one over another. Owing to numerous positive benefits such as low material waste, design flexibility and special tool elimination, it has been adopted in variety of industrial sectors. Fused deposition modeling (FDM) is a solid based thermoplastic AM process which can produce objects with complex shape using thermoplastic materials such as Acronitrile Butadiene Styrene (ABS) and Poly Lactic Acid (PLA), High Impact Poly Styrene (HIPS) and their composite variants to develop prototypes, conceptual models and end user industrial parts. Despite the attractive benefits FDM possess, it suffers from deficiencies such as anisotropic behavior, poor surface finish, dimensional errors and longer build time.A substantial amount of research has been conducted by the researchers in materials such as ABS and PLA to understand the effect of FDM input factors such as layer thickness, part density, infill pattern, raster angle and print speed in the past through different approaches such as one factor at a time (OFAT) and Experimental Design. newline
