FDM 3D Printed Automotive Spoilers: A Simplified Cost Analysis

open access: yesMacromolecular Symposia, EarlyView.
ABSTRACT Additive manufacturing (AM) has become an attractive alternative for producing customized and low‐volume automotive components, particularly in the aftermarket sector. This study presents a simplified theoretical cost analysis for manufacturing an automotive rear spoiler using fused deposition modeling (FDM).

Investigation of the Critical Overhang Angle in Fused Filament Fabrication Technology

open access: yesMacromolecular Symposia, EarlyView.
ABSTRACT In fused filament fabrication, overhangs are challenging because each deposited layer requires partial support from the previous layer. The frequently cited 45° guideline for unsupported printing originates from empirical practice and does not consistently represent process‐specific behavior.

Implications of heterogeneous embankment conditions for geoelectrical investigations on dams: A case study at Mactaquac Dam, Canada

open access: yesNear Surface Geophysics, EarlyView.
Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

Enhancing the Performance of 3D‐Printed Polyamide Composites Through Pre‐ and Post‐Processing Methods

open access: yesPolymer Composites, EarlyView.
FDM‐printed polyamide composites and post‐processing by annealing. ABSTRACT In this study, composite filaments with a short carbon fiber (CF) reinforced polyamide 612 (PA612) were produced using the FDM method at three different raster angles (0°, ±45°, 90°).
