Abstract The traditional sculptures are all from the artist’s careful carving, which is also the artistic presentation. With the rapid development of computer technology, digital technology has been applied to art landscape sculpture. Through RPM technology and 3D printing technology, we can rapidly shape and mass produce art landscape sculpture. Through computer aided technology, RPM technology and 3D printing technology, we can save the labor cost and mold opening cost of traditional sculpture, which shortens the production cycle and improves the precision and structure of sculpture. At the same time, we can also develop personalized sculpture, which has seriously impacted the traditional sculpture industry. Computer aided design is in line with the digital age of new technical concepts, which has become the main means of landscape sculpture creation. Through computer software, designers can complete the virtual sculpture design intention and intention. Through the generation of VR, manufacturers can better communicate with customers, which makes up for the shortcomings of traditional sculpture in construction. Firstly, this paper analyzes the related concepts. Then, this paper puts forward the necessity of applying computer aided technology to modern landscape sculpture. Finally, some applications are proposed.
