jaue2023010: Review on the Application of the 3D Printable Wood Plastic Composite in Building and Construction Fields

Abstract

 3D printing (3DP), also known as Additive Manufacturing (AM), is a manufacturing technique that fabricates objects by layer-by-layer stacking of material based on digital design models. Presently, numerous materials domi- nants in 3D printing (e.g. titanium, steel, plastics, and concrete) confront challenges such as high costs and insuffi- cient environmental sustainability, which act as primary impediments to the extensive implementation of 3DP within the architecture domain. Nowadays, Wood powder, a widely available and renewable lignocellulosic material, ex- hibits potential utility as an adjunctive material in 3DP, serving to mitigate production costs. The amalgamation of wood powder with synthetic or natural binders results in Wood Plastic Composite (WPC), which possesses potential in product fabrication and prototyping progress. The principal objective of this paper is to furnish a comprehensive background study on the applicability of WPC in 3D-printed architectural components. By reviewing pertinent lit- erature in the recent years, the developmental and investigational landscape of WPC materials has been assessed, along with their prospective utilization, merits, and associated risks in the realm of architecture and construction. The conclusion indicated that due to its economic feasibility and ample supply, WPC material, as a foundational resource for 3D printing applications, underscores profound potential to partially mitigate cost, environmental, and sustainability challenges inherent in the manufacturing landscape. However, it should be noted that the formulation of WPC material significantly influences the quality of printed products, thereby presenting technical challenges in printing operations. The inclusion of equipment and parameter control determination were also facing certain chal- lenges.
