As one of the most popular 3D printing filaments now. PLA is a multiple purpose material with high strength and minimal warping.PLA filament Extrusion Temperature Range: 190 Celsius degree  â?? 230Celsius degreeOur 1.75mm PLA 3D printer filament were tested and stirctly inspected, by our QC team and after five years market inspection to be sure to work with all of the FDM 3D printers in the market. Belive us!How to Storage:  Store in an Vacuum blister or bag at indoor temperature. PLA will absorb moisture; thereby affecting the dimensional tolerances of your 3D printer filament. Use airtight storage containers,  vacuum blister, buckets, or zip lock bags to keep the material free from humidity.FAQ:Q1.
