Abstract

Fused Deposition Modelling (FDM), a prevalent additive manufacturing technique utilising polymeric materials, facilitates intricate geometric customisation and rapid prototyping. The ongoing development of FDM technology emphasises the importance of the thermal characteristics of FDM-printed polymeric materials, which are essential for various applications, including aerospace and biomedical engineering. The thermal properties of FDM-printed polymeric materials, covering a wide range of thermoplastic polymers and composites, were examined in this review. Despite the versatility of FDM technology, thermal challenges persist in 3D printed parts, manifesting as anisotropy, voids, and sub-optimal conductivity, thereby impeding performance. Achieving precise control over printing parameters such as nozzle temperature, layer height, and speed is pivotal for optimising thermal properties. Additionally, controlled thermal treatments, like annealing, offer avenues for manipulating the crystalline structure of printed components to enhance the thermal conductivity. By elucidating the effects of reinforcements, this article aims to provide insights into potential enhancements and adjustments for developing thermally resistant FDM-based polymeric materials.

FDM 印刷聚合物材料的热性能：综述

熔融沉积建模（FDM）是一种利用聚合物材料的流行快速成型制造技术，可实现复杂的几何定制和快速原型制造。FDM 技术的不断发展强调了 FDM 打印聚合物材料热特性的重要性，这对航空航天和生物医学工程等各种应用至关重要。本综述对 FDM 打印聚合物材料的热特性进行了研究，其中包括各种热塑性聚合物和复合材料。尽管 FDM 技术用途广泛，但三维打印部件仍面临热挑战，表现为各向异性、空洞和传导性不达标，从而影响了性能。实现对喷嘴温度、层高和速度等打印参数的精确控制是优化热性能的关键。此外，受控热处理（如退火）也为操纵印刷元件的结晶结构以提高导热性提供了途径。通过阐明增强材料的效果，本文旨在为开发基于 FDM 的耐热聚合物材料提供潜在的增强和调整方法。

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
