Effect of printing layer thickness on water absorption and mechanical properties of 3D-printed wood/PLA composite materials
TLDR
In this article, the effect of printing layer thickness on technological properties of 3D-printed specimens fabricated from wood flour/PLA filaments having a diameter of 1.75mm was investigated.Abstract:
Effect of printing layer thickness on technological properties of 3D-printed specimens fabricated from wood flour/PLA filaments having a diameter of 1.75 mm was investigated. For this aim, four different printing layers, 0.05 mm, 0.1 mm, 0.2 mm, and 0.3 mm, were used in the production of the 3D-printed specimens. The water absorption of the specimens (28 days immersion in water) increased with increasing printing layer thickness while the thickness swelling decreased. The tensile and bending properties of the specimens significantly improved with decreasing printing layer thickness. The increase in the layer thickness caused bigger gaps, which increased the porosity in the cross section of the specimen. Higher porosity resulted in lower mechanical properties.read more

FDM 3D Printing of Polymers Containing Natural Fillers: A Review of their Mechanical Properties
TL;DR: The results analyzed in this review show that the mechanical properties of the most common materials, i.e., acrylonitrile-butadiene-styrene and PLA, do not benefit from biofillers, while other less widely used polymers, such as the polyolefins, are found to become more performant.
