Abstract
At present, 3D printing technology is becoming more and more popular, but the traditional learning method has some limitations. The price of 3D printing equipment is expensive, and there are some security risks in the process of learning operation. This paper mainly introduces the development and process research of high‐temperature environmental protection metal 3D printing equipment and realizes the design of 3D printing equipment combined with virtual reality technology. In this paper, the whole system of 3D printing equipment is designed and built. The function of motion platform and substrate in mechanical system is analyzed, and the detailed structure design is carried out; the control principle of control system including motion control system and temperature control system is introduced in detail, and the corresponding design and construction work is carried out. In this paper, the pure tin wire with low melting point was used as the experimental material, and the mechanical properties and microstructure of the metal tin forming parts were analyzed. On the basis of tin formation experiment, metal deposition experiment and metal forming error experiment were carried out with H65 high melting copper wire as the raw material. The experimental results show that when the printing speed is 35/mm, the dimensional accuracy of the products is high; the microhardness of the printed tin is close to that of the original material, the surface hardness is 12.50HV0.05, and that of the copper alloy is 14.31HV0.05; the tensile strength of tin wire after melt deposition is slightly reduced after tensile test for the machined tin parts, the ultimate tensile strength of the first group of specimens is reduced by 1.58%, and that of the second group is reduced by 0.74%. This paper combines virtual reality technology with 3D printing technology and develops 3D printing equipment for high‐temperature environmental protection metal using virtual reality technology. The forming and printing performance of the device is analyzed theoretically and experimentally. The experimental results verify the feasibility of the system and the practicability of the device.
Highlights
With the in-depth study of manufacturing industry, innovation and product development cycle has become the main contradiction of the product

According to the type of highenergy beam, metal 3D printing can be divided into selective electron beam casting, direct metal laser sintering, selective laser casting, selective laser sintering, etc. e metal 3D printing technology with laser as the heat source is the most mature and widely used [4]
Summary
With the in-depth study of manufacturing industry, innovation and product development cycle has become the main contradiction of the product. Compared with the traditional processing methods such as turning, milling, planning, and grinding, 3D printing is produced and manufactured in the form of addition, which has the characteristics of green environmental protection and is conducive to the manufacture of complex configuration items. It is widely used in automobile, aviation, aerospace, medical, education, electronic products, and other fields. Is paper will mainly solve several core problems, such as reducing the manufacturing, operating and operating costs of relevant equipment, improving energy utilization, deposition speed, and molding accuracy, and build a group of new high-temperature environmental protection metal material processing equipment and rapid prototyping to provide high-quality and high-efficiency additive processing strategy. It is of great social significance to promote the market application of metal additive technology and promote the transformation and upgrading of traditional industries
