Abstract

This study aims to optimise the water vapour adsorption capacity of polylactic acid (PLA) and wood composite materials for application in dehumidification systems through material extrusion additive manufacturing. By analysing key process parameters, including nozzle diameter, layer height, and temperature, the research evaluates their impact on the porosity and adsorption performance of the composite. Additionally, the influence of different infill densities on moisture absorption is investigated. The results show that increasing wood content significantly enhances water vapour adsorption, with nozzle diameter and layer height identified as the most critical factors. These findings confirm that composite materials, especially those with higher wood content and optimised printing parameters, offer promising solutions for improving dehumidification efficiency. Potential applications include heating, ventilation, and air conditioning systems or environmental control. This work introduces an innovative approach to using composite materials in desiccant-based dehumidification and provides a solid foundation for future research. Further studies could focus on optimising material formulations and scaling this approach for broader industrial applications.

摘要

本研究旨在通过材料挤出增材制造来优化聚乳酸（PLA）与木材复合材料在除湿系统中的水蒸气吸附能力。通过分析关键工艺参数，包括喷嘴直径、层高和温度，该研究评估了它们对复合材料孔隙率和吸附性能的影响。此外，还研究了不同填充密度对吸湿的影响。结果表明，增加木材含量可显著提高水蒸气吸附能力，其中喷嘴直径和层高被确定为最关键的因素。这些发现证实，复合材料，尤其是那些具有较高木材含量和优化打印参数的复合材料，为提高除湿效率提供了有前景的解决方案。潜在应用包括供暖、通风和空调系统或环境控制。这项工作引入了一种在基于干燥剂的除湿中使用复合材料的创新方法，并为未来的研究奠定了坚实基础。进一步的研究可以集中在优化材料配方以及将这种方法扩大规模以用于更广泛的工业应用。
