Problems solved by technology

[0002] In today's society, health is the most concerned issue for people. Air or water contains various pollutants that are harmful to human body. In addition, various harmful substances released from building decoration materials are also important factors that endanger people's health. At present, people often choose air Purifiers or water purifiers are placed indoors to purify air and water. However, these machines are expensive and require electric energy to be used. They are not economical and environmentally friendly. They also take up indoor space and are not beautiful. Prone to the problem of secondary pollution
[0003] The Chinese patent with the application number 201610628106.5 discloses an environmentally friendly clay material for 3D printing, including the following mass ratio raw materials: clay material: calcium carbonate powder: plant ash: specific synthetic agent: starch synthetic agent: water = 20-30: 8-16: 6-10: 4-9: 4-6: 10-25; with high wear resistance, impact strength, shock resistance, good plasticity, easy molding, high precision, etc., suitable for 3D printing molding technology, The raw materials used are rich in resources and can be recycled, but the material has no antibacterial and pollutant removal effects
[0004] The Chinese patent with application number 201611049167.2 discloses a bacteriostatic 3D printing wire and its preparation method. The preparation method includes: mixing water-based epoxy resin, silver nitrate and water, filtering and drying to obtain a bacteriostatic resin; Mixing acrylonitrile-butadiene-styrene plastic, the bacteriostatic resin, polylactic acid, photosensitive resin, nylon, aluminum powder, ceramic fiber, initiator, cross-linking agent and colorant and then melting to form a molten liquid M; Drawing and forming the molten liquid M to obtain the antibacterial 3D printing wire rod solves the problem that the surface of the 3D printing material is prone to mold after being stored in a humid environment for a long time, and the existing pollutants cannot be removed
