The main research content of this project is to further optimize the structural design, improve the appearance design, enhance the modularization level of products, promote the standardization of part design and processing, establish product assembly and testing specifications, and further improve the performance and stability of desktop FDM 3D printers. At the same time, it aims to make them more intelligent and easier to operate. Due to the low cost, safety, green, and pollution-free characteristics of desktop FDM 3D printers, they are the best choice for three-dimensional printing to enter fields such as education, home, maker, consumer, and design creativity, thus possessing a huge potential market. The project will continue to cooperate with Tongji University Science Park enterprise 'Maiji Intelligent Technology (Shanghai) Co., Ltd.' based on successful initial cooperation. Leveraging the funds and sales platform of Maiji, further breakthroughs in key technologies have been achieved to commercialize a series of desktop-grade FDM 3D printers with independent intellectual property rights (currently, research and development products have been exhibited multiple times at industrial fairs in Shanghai, Beijing, and other places, winning customer praise for their high-quality printing effects and achieving initial market recognition).
