“…In the use of Fused Deposition Modeling (FDM) devices, printing consumables are extremely easy to form buildup after cooling in the outer surface or internal flow channel of the nozzle, which can cause nozzle clogging in severe cases [1][2][3][4]. In the face of the cleaning problem of the nozzle blockage, the mechanical cleaning method, hot firing method, and chemical immersion method are often used.…”

Aiming at the problems of low cleaning efficiency, damaged nozzle, and high safety hazard in the traditional cleaning method of the fused deposition modeling (FDM) equipment nozzle, an environmentally friendly nozzle cleaning system was designed by using the chemical solvent and ultrasonic cleaning technology. The modular design of the nozzle clamping module can improve the nozzle loading efficiency and cleaning efficiency. The cleaning liquid circulation device makes the cleaning process automated under the coordination of the control module, which effectively reduces the safety hazards of the cleaning process. A thermal drying device is mainly used to speed up the drying rate of the nozzle. An exhaust gas purification device is used to absorb the volatile chemicals in the cleaning process and reduce pollution in the working environment.

“…High-temperature cleaning allows the organic dirt on the surface of parts to evaporate or burns it into gas and ash by heating at high temperatures. 2,3 However, the energy consumption in the cleaning process is large and long-term high-temperature environment will change mechanical properties of parts. In addition, the residual burning dirt that adheres to the surface of parts after high-temperature cleaning must be removed through post-treatment cleaning.…”

This paper aims to solve the problem of incomplete cleaning for blind hole remanufacturing blanks and damaging the matrix material in the cleaning process, a novel cleaning method by supercritical n-butanol is proposed. The feasibility of cleaning blind hole remanufacturing blanks is verified, and the mechanism of supercritical n-butanol cleaning is analyzed. The surface cleanliness of matrix structure, the properties change of matrix material and the environmental impact of the cleaning process are explored. The results indicated that there were no contaminants on the surface of cleaned matrix structure under the temperature 300°C, pressure 5.5 MPa, and cleaning time 10 min. Hardness, yield strength and tensile strength of matrix material after cleaning could increase by approximately 14%, 8%, and 5%, respectively. Compared with subcritical water, the oxidation degree of matrix structure cleaned by supercritical n-butanol was lower. Compared with high-temperature cleaning, seven environmental indexes of supercritical n-butanol cleaning process decreased significantly. Supercritical n-butanol cleaning is an ideal choice for blind hole remanufacturing blanks.
