Is photo-curing 3D printing reliable? How to pay attention to the gas produced during printing?

Unexpectedly, light-cured 3D printing has entered our lives. It can be found in shopping centers, schools and families. Maybe it's the ornaments on your desk, and the toys in children's hands are all printed in 3D. From millions of large commercial equipment to thousands of small printers, everything can be found on some e-commerce platforms. As far as the sales record of the platform is concerned, many models of 3D printers sell well. When it comes to which brand of UV-cured 3d printer is good, many people have a clear idea, but a recent study abroad shows that consumers will face health and safety risks when using UV-cured 3D printing products, which makes people wonder whether UV-cured 3D printing is reliable.

So far, the public has hardly noticed that they are exposed to the smell and other problems generated in the printing process of 3d printers. This situation has nothing to do with which brand of photocurable 3D printer is good. Any printer will have this problem when printing, and the public should be aware of the emissions of 3D printers. The essence of 3D printing is a material processing and molding technology. It has broad development prospects in aviation, aerospace, navigation, weapons, medical care, automobile, industry and other fields, and is called the core technology of the "third industrial revolution". Its main application fields are a small amount of equipment, innovation of new structural materials, personalized medical and industrial design, and creative products.

"As for whether 3D printing is polluted or harmful to human body and environment, I think it should be carried out from two aspects: the process of 3D printing and the use process after molding." Expert analysis said. Whether 3d printing is polluted or toxic has nothing to do with which brand of photocurable 3D printer is good, but depends on the materials used. At present, the 3D printing materials used are basically existing materials in the market, especially many polymer materials, which are very common in people's daily life and have frequent contact. After inspection and evaluation, they are allowed to be used in terms of pollution or toxicity.

Generally speaking, as a new manufacturing technology welcomed by the whole world, 3D printing itself does not have any problems. "Considering that some polymers (or chemicals) will produce certain (pollution or toxicity) emissions during the treatment process, if they are to be used as 3D printing materials, they must fully consider the possible emissions during the molding and heating process, and screen and study the materials. The unit responsible for the research, development and production of 3D printing materials will put the safety of material use in the first place.

For the problems in the printing process, factories or laboratories have corresponding protection conditions and measures, but after 3D printing enters the home, the protection will not be in place. Therefore, research should be intensified, new materials with excellent performance and environmental protection should be developed, and a set of safety standard system should be established from the aspects of design, materials, product performance, certification and inspection.
