The raw material of PLA 3D Filament comes from American company NatureWorks` Poly Lactic Acid, it is totally made by Ingeo raw materials. The life cycle of PLA begins with photosynthesis--plant absorbs carbon dioxide and then releases oxygen. Plants were sent to the factory to extract glucose after cutting, glucose transforms into lactic acid through fermentation, polymerization turns it out to be PLA, the PLA was changed into 3D materials by improving extrusion forming process. During the processing, reasonable modification formula is able to make sure that the product fits any norm of FDM printing, such as melt index, liquidity, adhesiveness, impact and so on, and the precise testing instrument could improve the precision of product.
he PLA is a new kind of biodegradable material, it is made by starch material which is extracted from renewable plant resources(such as corn). Starch material becomes lactic acid through fermentation and then converted to poly lactic acid by chemical synthesis. It has good biodegradable properties that it can be completely degrade into carbon dioxide and water by microorganism in the nature, it is recognized as environmentally friendly materials because it dose not pollute environment. Common plastic processing methods is still burning, this caused a large number of greenhouse gases into the air, but the plastic poly lactic acid is buried in the soil, its carbon dioxide directly into the soil organic matter or is absorbed by plants, not into the air, it won't cause the greenhouse effect. The PLA has the best strength of extension and stretch because of its favorable mechanical and physical properties, in addition to the basic characteristics of biodegradable plastic, it also bas its own unique features. Its combustion heat value is the same as incineration paper, it is half of the traditional plastics`, what is more, its incineration never release toxic gases such as nitrides and sulfide. Because our human bodies also contain lactic acid in this form of monomers, it means that this kind of decomposition products is secure in the hot melting printing process. Obviously, XYD-PLA material is the preferred printing material in home printing.
