Abstract
3D printing technology is becoming increasingly popular and is being practically applied in many fields. In education, 3D printing technology can make the content of subjects in general, and mathematics in particular, livelier and more intuitive. With the support of this technology, teachers can transform abstract, difficult-to-understand mathematical knowledge into content that learners can relatively easily grasp through real models. This paper presents the application of 3D printing technology in supporting the teaching and learning of the topic "Area of Flat Shapes". The research results show that during the pedagogical experiment, students actively participated in assigned tasks such as measuring and calculating results on 3D printed models, thereby discovering characteristics and properties to solve the problems. Additionally, through the exploration, students also gained a visual understanding related to the concept of integrals - a highly abstract concept in mathematics.
