Research on the Innovation and Implementation Path of 3D Printing Process Parameterized Teaching Practice Mode under the Perspective of Vocational Education

Abstract

Under the background of the deepening of national vocational education reform and the promotion of the strategy of industry-teaching integration, this study takes the “Ling Shi - Tewi” school-enterprise co-built 3D printing laboratory as a practical carrier, and aims at the traditional vocational education of 3D printing teaching, “theory and practice disconnect, weak innovation ability, insufficient industrial docking” and other pain points. To address the traditional vocational education teaching of 3D printing “theory-practice disconnect, weak innovation ability, insufficient docking with the industry” and other pain points, we have built a practical teaching mode with process parameter optimization teaching as the core. By deconstructing five types of key process parameters, such as equipment calibration, wall thickness and layer height, printing speed, filling density and support type, we innovatively put forward a four-stage progressive teaching mode of “parameter cognition-process decision-making-quality validation-cost assessment”, and incorporate educational theories such as CDIO, OBE and constructivism to form a “four-dimensional synergistic” teaching mode, which is based on the “four-dimensional synergistic” teaching mode. “Four-dimensional synergistic” teaching system. Practical research shows that the model has improved students' process optimization ability by 63.4%, and the conversion rate of industrialization of innovative works reaches 29.7%. The study further proposes a three-chain integration mechanism of “teaching chain - industry chain - innovation chain”, which realizes the transformation of production standards into teaching elements and the migration of industrial projects into practical training carriers through the dual-led “technology iteration community” and PDCA cycle management. This paper provides a replicable theoretical framework and practical paradigm for vocational education to deepen the integration of industry and education and to cultivate compound technical talents to support the new quality productivity, and its methodology can be extended to the teaching reform of other technical modules in the field of intelligent manufacturing.
