ABSTRACT

FDM (Fused Deposition Modeling) technology has developed since the 1990s, now a day, has been

top developing tendency in the technology and materials. The process of removing support material has

been studied for a long time, from the use mechanical force the application of more advanced techniques

such as: chemical and ultrasonic waves. From 1998, the ultrasonic energy has been studied and is the largest

company in the world to commercialize [2]. In Viet Nam, there is no scientific research to serve in this

field. In experiment studies on the application of ultrasound for removing material, the author presents

general principles and give experimental parameters affecting the separation process of support materials

of FDM use ultrasound energy

Keywords: FDM technology; Water-soluble; Removal support material from FDM technology;

Ultrasonic Machine for removing support material; Ultrasonic Apply.
