Because the vast majority of 3D printers on the market are used to print plastic materials, plastic in the production process plus plasticizers, plasticizers and other additives, these additives contain carcinogenic, teratogenic, mutagenic and other toxic Harmful Substance. When the temperature reaches above 100 ℃, serious germs and carcinogens that can not be seen by the naked eye will be greatly volatilized into the air, which will cause irreversible negative effects on the blood system diseases and mental retardation to adolescents. At present, Domestic and foreign prior art 3D print head melting plastic wire temperature is about 200 ℃.

In view of the above considerations, Qingdao UNON R & D team, worked hard, and finally successfully developed with edible wax as the basic material of the new 3D printing materials and 3D printers to replace the current market potential harm to human body plastic 3D printing materials to achieve The 3D printing history of the historic breakthrough, has now applied for national patents and world patents.
