Development and optimization of selective laser sintered-composites and structures for functional applications

Abstract

I would like to show my gratitude to the people for inspiring and encouraging me to devote into the scientific research and academic path when I was very young. I thank Prof. Wong Chee Chong and Prof. Shu Yang for many insightful discussions and encouragements during my undergraduate study at NTU and my internship at the University of Pennsylvania, USA. I owe my deepest gratitude to Dr. Chin Jia Min, Dr.Eric Ng and Dr. Wu Gaoxiang, who patiently trained and communicated with me for conducting laboratory works. They helped me to have passion in science and engineering rather than just simply work as a researcher. "Every day, every minute, every breath, every person around me truly is a gift and is precious."I owe the deepest gratitude to my parents and friends who have been supportingalong the way and caring about me. My parents have always educated me to be independent, keep studying and gain wisdom to pursue the dreams. I would like to give special thanks to my close friend Ms. Yang Jing, who was the only one that has known my entire tough and exciting journey over the past four years. My roommates Dr. Tao Kai and Ms. Yang Lixia have also taken care of me. It is a great treasure to establish the precious bonding and relationships with them during my life.

Thermally Conductive Polymer Composites with Hexagonal Boron Nitride for Medical Device Thermal Management

“…There are several articles about polymer PBF with thermally and electrically conductive fillers (e.g., carbon-based fillers such as carbon fibres [25], graphite [26], CNT [27] and graphene [28], or metal fillers such as Cu [29] and Ag [30]). The literature on PBF with thermally conductive and electrically insulating polymer-based composites is sparse, and most studies use PA12 as the polymer matrix [24], [31], [32].…”

“…Thermoplastic polyurethane (TPU) is a soft thermoplastic elastomer, offering high elasticity over a broad temperature range and high wear resistance [24], [32], [34]. It is commonly used for PBF and IM, and its suitability for biomedical applications has recently been highlighted [31].…”

Thermal Conductivity and Mechanical Properties of Polymer Composites with Hexagonal Boron Nitride—A Comparison of Three Processing Methods: Injection Moulding, Powder Bed Fusion and Casting

“…Among the most common are polyamide 12 (PA12) and thermoplastic polyurethane (TPU). Polyamide-based composites are also used in PBF, with glass-based fillers (e.g., glass fibres, glass beads) or carbon-based fillers (e.g., carbon black, carbon fibres, carbon nanotubes, graphite) [ 24 , 25 , 26 ]. There is a growing interest in developing new materials and composites for PBF, as well as the optimisation of PBF processing parameters.…”

“…TPU offers high elasticity over a broad temperature range and high wear resistance [ 24 , 26 , 35 ]. It is commonly used for PBF and IM, and its suitability for biomedical applications has recently been highlighted [ 25 ]. Therefore, the TPU “Ultrasint TPU 88A” (in the form of powder for PBF) was selected as the matrix for composites processed by PBF and IM in this study.…”
