“…3D printing (3DP) or additive manufacturing is an emerging technology that enables the creation of innovative designs and the combination of materials that were previously impossible or impractical to make. The incorporation of fillers in 3DP has demonstrated that the filler's physical features could be transferred to the 3D printed object (Montalvo Navarrete et al, 2018; Zeidler et al, 2018). These attractive traits have been demonstrated with wood (Mirko et al, 2016; Tao et al, 2017), clays (Revelo and Colorado, 2018), metals (Gibson et al, 2018), and seashells (Graichen et al, 2017; Singamneni et al, 2018a; Zeidler et al, 2018).…”

Additive manufacturing or 3D printing has the potential to displace some of the current manufacturing techniques and is particularly attractive if local renewable waste resources can be used. In this study, rice husk, and wood powders were compounded in polylactic acid (PLA) by twin screw extrusion to produce filaments for fused-deposition modeling 3D printing. The biomasses were characterized in terms of physical features (e.g., particle size, density) and chemical compositions (e.g., solid state nuclear magnetic resonance, ash content). The two biomasses were found to have a different impact on the rheological behavior of the compounds and the extrusion process overall stability. When comparing the complex viscosity of neat PLA to the biomass/PLA compounds, the integration of wood powder increased the complex viscosity of the compound, whereas the integration of rice husk powder decreased it. This significant difference in rheological behavior was attributed to the higher specific surface area (and chemical reactivity) of the rice husk particles and the presence of silica in rice husks compared to the wood powder. Color variations were also observed. Despite the biomass filler and rheological behavior differences, the mechanical properties of the 3D printed samples were similar and predominantly affected by the printing direction.

“…Thermal stability and safe zone of heating and processing of wood flour filled PLA or PP filament were investigated. Four zones, namely dehydration, a stable zone for FFF, slow decomposition, and rapid decomposition were well defined . Different degrees of thermal degradation temperature shifts were observed for cocoa shell waste PCL filaments with different lignocellulose contents from TGA analysis.…”

Fused filament fabrication (FFF) with thermoplastic filaments is the most popular 3D printing technology. The continuous polymer filaments undergo a series of thermal processes, including heating, melting, cooling, and solidification. Therefore, it is necessary to investigate the thermal behavior of polymer filaments. The present study aims to provide a fundamental study of the thermal decomposition behavior and the isothermal melting crystallization behavior of nanocellulose filled polylactic acid (PLA) filaments. The influences of nanocellulose contents on the thermal decomposition properties such as onset temperature (T onset ), the temperature at 20-wt % conversion (T α20 ), and the temperature at the peak decomposition rate (T p ) were examined by thermogravimetric analysis (TGA). The effects of nanocellulose contents on the glass transition temperature (T g ) and the melting temperature (T m ) were studied by differential scanning calorimetry (DSC). Effects of nanocellulose and polyethylene glycol (PEG) incorporation on the thermal decomposition activation energy, isothermal melting crystallization rate, and semi-crystallization time are also investigated. The addition of nanocellulose improves the thermal stability of PLA filament, whereas the addition of plasticizer PEG decreases the thermal stability. TGA and DSC kinetic analyses indicate that nanocellulose alone or together with PEG could drastically increase the crystallization rate and shorten the semi-crystallization time.

“…Despite a great deals of attention and studies on the 3D printing of conventional and advanced materials, the number of studies on the AM of bio‐based reinforced composites is limited. [ 24 ] The fabrication of lightweight cellular structures with enhanced mechanical properties, which are 3D printed by fiber‐reinforced composite filaments, is the result of recent advances in AM technology [12f,25] . Producing architected cellular composites out of biological resources (i.e., bio‐based PLA) and waste materials (i.e., wood fibers) with enhanced multifunctional properties including stiffness and ultimate strength can be a turning point in sustainable design and fabrication of advanced materials.…”

One class of state-of-the-art lightweight, energy-efficient materials with enhanced material properties is "architected cellular solids." Their exotic properties (e.g., high strength-to-weight ratio, high energy absorption capability and tunable multiphysical properties) mainly stem from their rationally designed underlying architectures (e.g., cell topology and cell connectivity) and partially from the properties of their constituent materials. [1] Cellular solids, so-called cellular-based "metamaterials," upon showing unprecedented properties, have recently received considerable attention due to their potential applications in aerospace, automotive, energy, robotics and biomedical sectors as high-performance lightweight panels, energy absorbers, morphing structures, noise reduction, waveguide devices, programmable battery electrodes, and bioimplantable medical devices. [2] Recently, advances in "3D printing," interchangeably called "additive manufacturing" (AM), have shed light on strategies for design and realization of advanced materials (including "cellular solids" and "architected metamaterials") with controlled material composition and architectural complexity. A large number of studies have been conducted to investigate the correlation between specific mechanical properties and the architecture of 3D-printed advanced materials. [3] Fast prototyping, material saving, waste minimization, design freedom, and the capability to manufacture complex architectures are the main 3D printing advantages. [4] 3D printing is a fabrication process for constructing free-form materials and structures from a computer-aided design model. The printing process typically involves layerupon-layer fabrication that enables the production of complex geometries that would be impossible by conventional manufacturing processes. [5] Several methods can be adopted for 3D printing: direct metal laser sintering (DMLS), selective laser melting (SLM), and electron beam melting (EBM) for printing metallic powders; selective laser sintering (SLS) for printing polymeric and metallic powders; laminated object manufacturing (LOM), direct foam writing, 3D extrusion freeforming of ceramics (EFF), and lithography-based ceramic manufacturing (LCM) for ceramic-based materials; stereolithography apparatus (SLA) and digital light projection (DLP) for printing photopolymeric resins; and fused deposition modeling (FDM) for printing thermoplastic polymers. [6] The simplicity, reliability, affordability (minimal waste, low processing and operational cost), multimaterial (multinozzle) printing capability, and adaptability to new materials, and composites have made FDM one of the most
