PLA filament with improved physical properties PLA + is a PLA-based 3D printing filament with enhanced physical properties. The increased strength and toughness makes it an excellent choice for a wide range of printing applications. Plant-Based Material PLA + is made from starch raw materials derived from renewable plant resources. Better Toughness Compared to conventional PLA, eSUN PLA+ has better physical properties. The increased toughness makes it less susceptible to breakage. High Printer Compatibility eSUN PLA+ is compatible with most FDM 3D printers. Vacuum-Sealed Packaging Vacuum-sealed packaging protects your filament from dust, dirt and moisture. Printing eSUN PLA+ The printing temperature of PLA + is about 20 degrees Celsius higher than normal PLA. The recommended printing temperature is about 210 - 230°C. A heating bed is not necessary. However, if a heating bed is available, it can be heated up to 45 - 60°C. How to Store your Filament If you are not going to use your printer for more than a few days, please remove the filament from the nozzle to protect it. To prolong the life of your filament, please return the unsealed filament to the original vacuum bag and store it in a cool, dry place after printing. If you have a filament box, store your filament there. When storing your filament, please feed the loose end of the filament through the holes on the edge of the filament spool to avoid unwinding. This way it will be pulled in properly the next time you use it.
