“…This procedure is commercially called chemical smoothing, and has been used by researchers to improve the quality of 3D printed surfaces, particularly in mold manufacturing practices, like previous work from Bin et al. [ 46 ] which assured watertight surfaces with this procedure. Additionally, the component must be cooled down at open air or with proper ventilation to achieve even results, so the alcohol residuals would evaporate from the surface appropriately.…”

The purpose of this review is to explore various techniques used in the optimization of process parameters of 3D printing machines for different applications. Fused Deposition Modeling (FDM) is an emerging technology that has been widely used in diverse areas including new product development, mould manufacturing, etc. FDM is the process of depositing the material in a layer-by-layer manner to manufacture the part. FDM provides a lot of flexibility in fabricating a part. Many complex parts can be manufactured by FDM easily which are very difficult to manufacture through conventional manufacturing methods. However, build-in time, manufacturing speed, and mechanical strength of FDM fabricated parts are still challenging and critical. The quality of FDM fabricated parts is affected by various machining parameters, such as air gap, build orientation, infill percentage, raster angle, raster width, layer thickness, etc. The selection of significant process parameters needs to be identified and optimized as per the usage of apart. Many researchers have used different techniques, such as the design of experiment (DOE) technique, response surface method(RSM), genetic algorithm(GA), artificial neural network(ANN), and fuzzy, to optimize the FDM process parameters to improve the desired part quality, such as mechanical properties, and dimensional accuracy. This survey paper attempts to critically review various research articles published on the optimization of process parameters to improve the performance parameters of FDM.

Polylactic acid (PLA) has good biocompatibility and biodegradability, which is widely used in fused deposition modeling (FDM) technology. But its disadvantages are also very prominent, such as low strength, and high brittleness. Stainless steel material has high mechanical properties and good biocompatibility, so PLA/stainless steel composite material has the advantages of both materials. In this paper, the effects of FDM forming parameters, such as nozzle temperature, extrusion speed, printing speed, nozzle height from the substrate, layer thickness and nozzle diameter, on the single-channel direct writing forming quality were studied from the angle of line height and line width of PLA/stainless steel composites. The results show that selecting appropriate FDM process parameters can effectively improve the quality of single-channel molding, and the printed lines have certain shrinkage. The ratio of line height to line width exceeds 100%. It provides a theoretical reference for the subsequent forming of PLA/stainless steel composite parts based on FDM.
