Development of CNT-photocurable Resin Composites for 3D Printed Heater Fabrication

Abstract

After 3D printing or additive manufacturing technology was first developed, the growth of the 3D printing industry has been slow due to problems such as equipment, materials, and manufacturing speed. However, with the 4th Industrial Revolution, innovative technologies such as the Internet of Things, big data, and artificial intelligence have spread, and then 3D printing, which can fabricate products of various shapes attracts attention. In particular, a photocurable 3D printing such as SLA (Stereolithography) or DLP (Digital Light Processing) is widely used for research purposes as it has the advantage of being able to easily modify the material because resin is just mingled by various liquid materials. In addition, with the recent rapid growth of electricity heating requirement, demands for space-efficient heating systems are increasing regardless of fields such as aerospace, marine, electric vehicle, agriculture, and housing. On the other hand, CNT is a next-generation smart material having high electrical and thermal conductivity, and its effectiveness has been proven and research is ongoing. Therefore, in this study, CNT was used for heater efficiency, photocurable resin composites including CNT was developed, and the printability was studied.
