“…Different types of binding agents for wood to print objects are reported in the scientific literature, such as polylactic acid (PLA), thermoplastic polyurethane (TPU), urea formaldehyde (UF), polyhydroxyalkanoates (PHA), gypsum, polyvinyl alcohol (PVA) etc. [ 47 , 95 , 96 , 98 , 99 , 102 , 103 , 104 , 105 , 106 ]. For example, Henke and Treml (2013) used various binders with spruce shavings (sized between 0.8 and 2 mm), such as gypsum, methylcellulose, sodium silicate and cement.…”

Recently, Fused Filament Fabrication (FFF), one of the most encouraging additive manufacturing (AM) techniques, has fascinated great attention. Although FFF is growing into a manufacturing device with considerable technological and material innovations, there still is a challenge to convert FFF-printed prototypes into functional objects for industrial applications. Polymer components manufactured by FFF process possess, in fact, low and anisotropic mechanical properties, compared to the same parts, obtained by using traditional building methods. The poor mechanical properties of the FFF-printed objects could be attributed to the weak interlayer bond interface that develops during the layer deposition process and to the commercial thermoplastic materials used. In order to increase the final properties of the 3D printed models, several polymer-based composites and nanocomposites have been proposed for FFF process. However, even if the mechanical properties greatly increase, these materials are not all biodegradable. Consequently, their waste disposal represents an important issue that needs an urgent solution. Several scientific researchers have therefore moved towards the development of natural or recyclable materials for FFF techniques. This review details current progress on innovative green materials for FFF, referring to all kinds of possible industrial applications, and in particular to the field of Cultural Heritage.

“…The finished product is a 125 µm mesh made of wood powder [ 35 ], as shown in Figure 1 e. The particle size analyser equipment was utilised in the dry measurement mode, and a random 150 g sample of wood dust was obtained to evaluate the size content of the wood dust used, and Figure 2 tabulates the data resulting from the particle size analyser. This size was chosen wisely related to the review according to Nasereddin et al [ 41 ] and Das et al [ 42 ]. Cleaning wood filler in a mixture of dirt particles, grease, and tiny metal fragments is a particularly difficult process.…”

“…The reason for selecting the alkaline treatment process is the direct influence of the hydroxyl group on cellulosic fibrils, the extraction of lignin and hemicellulose compounds, and ease of processing [ 39 ]. The wood dust was soaked in NaOH solution with 6% concentration at room temperature for 2 h [ 41 , 42 ]. After that, the wood was washed several times thoroughly with running distilled water and dried in an oven at a temperature of 60 °C for 24 h [ 35 ].…”

Effect of Wood Dust Fibre Treatments Reinforcement on the Properties of Recycled Polypropylene Composite (r-WoPPC) Filament for Fused Deposition Modelling (FDM)

et al. 2023

The efficacy of wood dust fibre treatment on the property of wood dust reinforced recycled polypropylene composite (r-WoPPC) filament was investigated. The wood dust fibre was treated using alkali, silane, and NaOH-silane. The treated wood fibre was incorporated with r-PP using a twin-screw extruder to produce filament. The silane treatment on wood dust fibre enhances interfacial bonding between wood fibre and recycled PP; hence, a filament has the highest wire pull strength, which is 35.2% higher compared to untreated and alkaline-treated wood dust filament. It is because silanol in silane forms a siloxane bond that acts as a coupling agent that improves interfacial bonding between wood dust fibre and recycled PP. The SEM micrograph of the fracture structure reveals that treated silane has strong interfacial bonding between wood dust fibre and recycled PP, having minimal void, gap, and good fibre adhesion. The water absorption test results indicate that filament with treated wood dust absorbs less water than filament with untreated wood because the treatment minimizes the gap between wood fibres and recycled PP. The FTIR analysis identified the presence of silane on the wood dust surface for silane-treated wood dust. The DSC studies suggest that the temperature range 167–170 °C be used in the extrusion machine to produce r- WoPPC filament. As a result, r-WoPPc filaments containing silane-treated wood dust have better mechanical properties and have a greater potential for usage in FDM applications.

“…New processes that allow 3D printing with organic materials have been recently developed [ 26 , 27 ]. For the fused deposition modelling of timber, wood is ground to particles and mixed with various thermoplastics to create continuous printing filaments or pellets [ 28 ]. Both these materials cause timber to lose its natural material structure that provides strength, resulting in relatively weak printed structures [ 29 ].…”

Wood-Veneer-Reinforced Mycelium Composites for Sustainable Building Components

et al. 2022

View full text Add to dashboard Cite

The demand for building materials has been constantly increasing, which leads to excessive energy consumption for their provision. The looming environmental consequences have triggered the search for sustainable alternatives. Mycelium, as a rapidly renewable, low-carbon natural material that can withstand compressive forces and has inherent acoustic and fire-resistance properties, could be a potential solution to this problem. However, due to its low tensile, flexural and shear strength, mycelium is not currently widely used commercially in the construction industry. Therefore, this research focuses on improving the structural performance of mycelium composites for interior use through custom robotic additive manufacturing processes that integrate continuous wood fibers into the mycelial matrix as reinforcement. This creates a novel, 100% bio-based, wood-veneer-reinforced mycelium composite. As base materials, Ganoderma lucidum and hemp hurds for mycelium growth and maple veneer for reinforcement were pre-selected for this study. Compression, pull-out, and three-point bending tests comparing the unreinforced samples to the veneer-reinforced samples were performed, revealing improvements on the bending resistance of the reinforced samples. Additionally, the tensile strength of the reinforcement joints was examined and proved to be stronger than the material itself. The paper presents preliminary experiment results showing the effect of veneer reinforcements on increasing bending resistance, discusses the potential benefits of combining wood veneer and mycelium’s distinct material properties, and highlights methods for the design and production of architectural components.
