500 ## - GENERAL NOTE
General note Additive Manufacturing (AM) has transformed manufacturing by enabling the fabrication<br/>of complicated geometries with less material waste which is particularly beneficial in a<br/>variety of industries, including aerospace, automotive, healthcare, and consumer goods.<br/>Fused Deposition Modeling (FDM) is a prominent approach in the realm of AM, attributed<br/>to its economic practicality, user-friendly execution, and material flexibility. The persistent<br/>of warpage in FDM poses a critical challenge in FDM affecting dimensional accuracy,<br/>fitment and mechanical reliability of components. Despite advancements, a lack of<br/>comprehensive studies on the combined effects of key process parameters limits the ability<br/>to predict and mitigate the effect of warpage. This research aims at providing approaches<br/>to rectify warpage in FDM-printed parts a priority based on process improvements. This<br/>research investigates three critical printing parameters i.e., raster pattern, bed temperature,<br/>and infill density. Samples are printed with various printing conditions and warpage is<br/>measured followed by validation using FEA analysis. The initially developed predictive<br/>model gained relatively high precision with overall variance of value being less than 10%<br/>in accordance with experimental tests. FEA simulations show that the FCC raster pattern<br/>decreases warping by 40% than the grid raster pattern. Similarly, 80ºC bed temperature<br/>decreases warpage by 30% comparing with 40ºC. Infill density of 90% decreases warpage<br/>by 20% more than 10% infill density. Optimizing key process parameters in FDM can<br/>significantly reduce warpage, improving dimensional accuracy and mechanical reliability<br/>in precision-critical applications.
