“…Therefore, this section describes a micro-screw extrusion AM system suitable for the printing of fully biodegradable composites [31]. Specifically, it covers the design of micro-screws for different types of materials (crystalline and noncrystalline materials), the preparation of wood flour-filled polyhydroxyalkanoate (PHA) composites, and the elaboration of the relationship between materials properties, device design, and printed part performance [32].…”

The properties of 3D printed products are closely related to the raw materials and the processes by which they are made. The processes of melting, depositing, and cooling of polymers affect the orientation, crystallinity, and microstructure of the product. These in turn influence the thermal, mechanical, optical, and other properties of the printed part. Among various 3D printing methods, filament and pellet extrusion-based fused deposition modeling (FDM) 3D printing is the cheapest and mostly adopted. In this chapter, the devices and some biodegradable polymer materials applicable in FDM 3D printing are briefly introduced. In the first part, preparation and the structure-property relationship of polylactic acid/polybutylene succinate blend filaments are discussed. Rheological, thermal properties of the raw materials and the properties of the printed parts were characterized. In the second part, a pellet extrusion 3D printer with a micro-screw was designed for using pellets of polyhydroxyalkanoate composites, which are difficult to produce filaments. The relationship between the screw parameters of the micro-screw extrusion 3D printer, rheological properties of the composites, and the printed product performance has been investigated. Combining theory and practical application will provide guidance for formulating biodegradable polymer materials and designing equipment for FDM 3D printing.

“…Another gap in the literature is the limited understanding of the effects of process parameters on the properties of wood-based AM products. While there have been some studies investigating the effect of parameters such as printing temperature and speed on the mechanical properties of wood-based AM parts (Tian et al 2021), there is still a need for more systematic and comprehensive studies on this topic.…”

Wood-based additive manufacturing (AM), some examples of which are called 3D printing, is a promising technology for reducing the environmental impact of manufacturing and increasing the sustainability of the construction industry. This review paper provides an overview of various AM methods, including commonly used wood-based techniques and the mechanical and physical properties of their products. The paper also discusses challenges related to precision and surface finish in wood-based AM and identifies areas for future research, including the effects of wood species, particle size, and processing parameters on the mechanical properties and dimensional stability of wood-based AM products. The review concludes by discussing the potential implications of wood-based AM for sustainable materials and the construction industry, along with recommendations for future research such as the development of new wood-based AM techniques and exploration of new applications for this technology. This paper provides valuable insights into the current state of wood-based AM research and its potential to revolutionize sustainable manufacturing practices.

“…Screw-assisted MEX additive manufacturing appeared in the mid-2000 s, typically adapting miniaturized vertical geometrically simplified single-screw extruders coupled to a positioning system, with a single heating zone and flood fed [5]. Since then, screw-assisted deposition tools have been further developed and find application in recycling [6,7], biofabrication [8][9][10][11][12], low-cost metal and ceramic 3D printing [13][14][15][16], and personalized medicine [17][18][19]. Although single screw extruders offer an improved control over the plastication process and can reach higher deposition rates, their output is not solely dictated by the screw speed but also depends on nozzle geometry and polymer rheology.…”
