- Abstract
Lamination is the process of joining two or more distinct material layers together. Generally a resin is used to bind the different materials used in the laminate. This research presents a new method to create laminates without binders or resins using 3D printing. 3D printing offers a wide range of prospects, due to its distinct advantages across numerous industries. Changing the process parameters that affect mechanical qualities has been the subject of numerous studies. The goal of this work is to fabricate a bi-material laminate using fused deposition modelling and also investigate how the dimensional precision and surface roughness of a PLA-PMMA laminate affect its tensile strength. The specimens used in this study are made following ASTM D638 Type I standard. To investigate their impact on tensile qualities and quality attributes, three process parameters--layer height, infill density, and raster width--were chosen. To analyse the impact of the parameters taken into consideration on the component's dimensional accuracy, tensile strength, and surface quality, Taguchi's optimization is used. Layer height plays a prominent role on the specimen's thickness. Surface roughness is found to be most strongly influenced by layer height, while tensile strength is exponentially influenced by raster width.
