Abstract: In the context of new quality productive forces, societal development and industrial changes present new challenges for the training of chemical professionals, placing higher demands on universities in the teaching of the Principles of Chemical Engineering course. Leveraging 3D-printed models of chemical unit operation equipment, the teaching team proposes a reform strategy centered on these models. By utilizing the creativity and digital capabilities of 3D printing technology, this approach integrates the teaching of chemical unit operations with the teaching of chemical principles and theories. This method effectively enhances students' overall abilities and fosters their ideological and political literacy. According to a questionnaire survey, students report that the implementation of this method aids their learning in the following areas: increased learning interest (18%), improved spatial imagination (18%), better intuitive understanding of abstract concepts (16%), and enhanced practical operation skills (15%).

Key words: New quality productive force, 3D printing, Principle of chemical engineering, Teaching practice, Ideological and political literacy
