Study of Dynamic Mechanical Properties of Fused Deposition Modelling Processed Ultem Material

Abstract

Fused Deposition Modelling (FDM), a renowned Rapid Prototyping (RP) process, has been successfully implemented in several industries to fabricate concept models and prototypes for rapid manufacturing. This study furnishes terse notes about the material damping properties of FDM made ULTEM samples considering the effect of FDM process parameters. Dynamic Mechanical Analysis (DMA) is carried out using DMA 2980 equipment to study the dynamic response of the FDM material subjected to single cantilever loading under periodic stress. Three FDM process parameters namely Build Style, Raster Width and Raster Angle were contemplated. ULTEM parts are fabricated using solid normal build style and three values each of raster width and raster angle. DMA is performed with temperature sweep at three different fixed frequencies of 1, 50 and 100 Hz. Results were obtained for dynamic properties such as Maximum Storage Modulus, Maximum Loss Modulus, Maximum Tan Delta and Maximum Complex Viscosity. The present work discusses the effect of increasing the frequencies and temperature on FDM made ULTEM samples using different FDM process parameters.

Experimental Investigations of Process Parameters Influence on Rheological Behavior and Dynamic Mechanical Properties of FDM Manufactured Parts

“…Out of these, the five process parameters namely, layer thickness (A), air gap (B), raster angle (C), build orientation (D), road width (E) have already been identified as the most significant FDM process parameters by several researchers [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] in their studies of FDM process optimization and therefore these main factors are considered in this paper to study their effects on the selected responses. The sixth parameter, the 'number of contours' is also considered in this study along with five main process parameters.…”

“…A relatively large amount of research [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] have been performed to investigate the impact of process conditions on static mechanical properties (static loading) of the Acrylonitrile butadiene styrene (ABS) parts fabricated by FDM process using empirical models and applied design of experiments through statistical techniques such as regression analysis and analysis of variance (ANOVA). Unfortunately, a systematic experimental investigation of the effect of input parameters on the rheological and dynamic mechanical properties of part manufactured by FDM does not exist in the literature.…”

Characterization of the Mechanical Properties of FFF Structures and Materials: A Review on the Experimental, Computational and Theoretical Approaches

“…A frequency sweep from 10 Hz to 100 Hz using three different temperatures was performed by Arivazhagan and Masood [77] on ABS samples fabricated with fully dense top and bottom layers, and with different raster patterns. The raster patterns tested were unidirectional and bi-directional, quasi-solid and partially filled.…”

Shrinkage and Warpage Optimization of Expanded‐Perlite‐Filled Polypropylene Composites in Extrusion‐Based Additive Manufacturing

“…The most frequently used thermoplastic polymers in FFF are acrylonitrile–butadiene–styrene (ABS) and polylactic acid . Additionally, a considerable number of other studies has been performed on amorphous polymers such as polymethylmethacrylate, polycarbonate, polyetherimide, polyphenylsulfone, and polystyrene‐based polymers . However, only few studies on semicrystalline polymers in FFF, such as polycaprolactone, polybutylene terephthalate, and polyetheretherketone, have been reported.…”
