Physical properties of wood-based materials for liquid deposition modeling

Purpose: The purpose of this study is to quantify the vertical shrinkage rates and the mechanical strength of three-dimensional (3D) printed parts for a variety of wood-based materials for liquid deposition modeling. Design/methodology/approach: The overall hypothesis was that a well-chosen combination of binders, fibers and fillers could...

Comparing environmental impacts of metal additive manufacturing to conventional manufacturing

Metal additive manufacturing (AM) is revered for the design freedom it brings, but is it environmentally better or worse than conventional manufacturing? Since few direct comparisons are published, this study compared AM data from life-cycle assessment literature to conventional manufacturing data from the Granta EduPack database. The...

Sustainable Product Design Education: Current Practice

Current production and consumption patterns are unsustainable, causing irreversible damage to the environment and human health and well-being. Designers play a vital role in resolving this problem—their decisions affect product manufacturing, distribution, use, and disposal—and hence they must be aware of the positive and negative impacts of...

A study of graphical representations of uncertainty in LCA guide

This study user-tested different data visualizations for highly uncertain life cycle assessments (LCAs) to determine what best supported decision-making. Precise LCAs can only be performed once designs are finalized, due to the information necessary to complete them, but design changes in such late stages are costly. If designers could have...
