A Pegboard-based Side-mounted Desk Organizer Fabricated via Fused Deposition Modeling

Abstract

To address the issue of insufficient desktop space in modern office and home environments, this study developed a side-mounted desktop organizer based on a pegboard. Comparative experiments on printing accuracy and mechanical performance were conducted using three commonly used 3D printing filaments in the market: polylactic acid (PLA), polyethylene terephthalate glycol (PETG), and acrylonitrile-butadiene-styrene (ABS). The results showed that among the X, Y, and Z directions, PLA specimens exhibited the smallest dimensional errors, PETG showed intermediate values, and ABS displayed the largest. In terms of tensile strength and elastic modulus, PLA specimens demonstrated the highest values, PETG ranked second, and ABS had the lowest. Therefore, PLA filament was selected as the printing material for the desktop organizer, and fused deposition modeling (FDM) technology was used to complete the 3D printing of the prototype. The 3D-printed desktop organizer features good surface quality and high assembly accuracy, effectively expanding the vertical storage space of the desk and enabling organized storage of small items, such as stationery and cables, demonstrating strong potential for application and promotion.
