Optimizing Layer Thickness and Width for Fused Filament Fabrication of Polyvinyl Alcohol in Three-Dimensional Printing and Support Structures

Abstract

Polyvinyl Alcohol (PVA) is frequently applied as a support material in 3D printing, especially in the crafting of intricate designs and projecting elements. It functions as a water-soluble filament, often paired with materials like ABS or PLA. PVA serves as a momentary scaffold, supporting the jutting segments of a 3D model throughout the printing process. Subsequent to printing, the primary component can be effortlessly isolated by dissolving the PVA support using water. PVA, being a pliable and eco-friendly polymer, is susceptible to moisture. Its aqueous solubility renders it a prime selection for bolstering 3D print structures. In this investigation, equivalent-sized samples were 3D printed utilizing an Ultimaker 3D printer to assess the potency of PVA-generated specimens. Tensile examinations were executed on each sample employing a testing apparatus. The durability of the specimens was notably impacted by the input parameters, specifically the stratum width and stratum thickness. Strength dwindled as stratum width increased, whereas it rose with augmented stratum thickness. A few specimens with heightened stratum width and compromised quality displayed subpar performance during the tensile assessment. The findings unveiled a peak tensile strength of 17.515 MPa and a maximum load of 1600 N. Attaining an optimal degree of material utilization led to a decrease in filament consumption by 8.87 g, all the while upholding a MTS (maximum tensile strength) of 10.078 MPa.

Capability Enhancing of CO2 Laser Cutting for PMMA Sheet Using Statistical Modeling and Optimization

“…By providing a structured approach to experimentation, RSM significantly contributes to advancing scientific understanding and technological innovation, making it an indispensable tool for optimizing complex systems and processes. RSM facilitates a comprehensive understanding of the intricate relationships between FDM [28] and EDM [29,30] parameters, such as raster angle, air gap, raster width, current, pulse on time, and pulse off time, and critical performance measures like compressive stress, percentage deformation, breaking stress, material removal rate, tool wear rate, and surface roughness. The utilization of RSM not only aids researchers in uncovering the optimal combinations of parameters for enhanced outcomes but also contributes to advancing the efficiency and effectiveness of these advanced manufacturing techniques [31,32].…”

Correlation between Infill Percentages, Layer Width, and Mechanical Properties in Fused Deposition Modelling of Poly-Lactic Acid 3D Printing

“…Consequently, concerted efforts have been marshaled to devise treatment methodologies capable of mitigating these Enhancements in the mechanical attributes, surface characteristics, and dimensional accuracy of FDM-printed components are attainable through the judicious application of techniques such as laser or acetone vapor treatments [30]. The choice of FDM printing parameters, encompassing layer thickness, infill percentage, and print speed, exert a discernible influence on the mechanical integrity and strength of PLA-fabricated specimens [31]. Optimisation of these parameters has the potential to confer superior tensile strength and toughness.…”
