在这篇文章中，将澳大利亚坚果壳（一种来自林业和农业的废弃物）转化为三维（3D）打印的创新微木材产品的可行性通过组成用于熔融沉积建模的木塑原料进行了研究。将不同比例的微研磨澳洲坚果壳和丙烯腈丁二烯苯乙烯（ABS）塑料与粘合剂混合以挤出一系列长丝。通过使用商业3D打印机，这些细丝有助于制造在拉伸和压缩下测试的样本。结果表明，印刷样品的澳洲坚果壳ABS复合材料提供了一个可行的替代市售木材聚合物复合材料长丝。虽然它们具有相似的机械性能，但它们具有较低的密度，使其适用于一系列轻质产品应用。该研究表明，与传统的木丝相比，澳大利亚坚果壳丝具有增强的性能，因此在增材制造中使用它有新的机会。
In this article, the feasibility of turning macadamia nutshells, a waste product from the forestry and agricultural industries, into a three-dimensional (3D) printed, innovative, microtimber product is examined by composing a wood plastic feed stock for fusion deposition modeling. Different ratios of microground macadamia nutshells and acrylonitrile butadiene styrene (ABS) plastics were mixed with a binding agent to extrude a range of filaments. By using a commercial 3D printer, these filaments helped to fabricate specimens that were tested in tension and compression. The results show that printed samples of macadamia-nutshell-ABS composites offer a viable alternative to commercially available wood polymer composite filaments. Although they possess similar mechanical properties, they have a lower density, making them suitable for a range of lightweight product applications. The research demonstrates that there are new opportunities for the use of macadamia nutshell filament in additive manufacturing as a result of its enhanced properties compared with traditional wood filaments.
