PLA (Polylactic Acid) is one of the two most commonly used desktop 3D printing filaments (with the other being ABS filament). It is the "default" recommended material for many desktop 3D printers, and with good reason - PLA is useful in a broad range of printing applications, has the virtue of being both odorless and low-warp, and does not require a heated bed. PLA filament is also one of the more eco-friendly 3D printer materials available; it is made from annually renewable resources (corn-starch) and requires less energy to process compared to traditional (petroleum-based) plastics. Outside of 3D printing, PLA plastic is often used in food containers, such as candy wrappers, and biodegradable medical implants, such as sutures. Specifications: Filament Material: PLA Specific Gravity: 1.25 gr/cm3 Size: 1.75 mm -/+ 0.05 mm Net Weight: 0.5Kg -/+5% due to packaging variables. 1.0Kg -/+5% due to packaging variables. Printing Information: Extruder: 190 – 220 oC Bed: 40 – 60 oC (Only for big parts) Working Temperature: Starts losing mechanical strength at 60 oC Features: Lower melting point for easier printing Free from harmful or hazardous materials Lower shrinkage rate High rigidity with minimal flex Produces higher quality prints Proper for printing large parts with almost no warping Can be printed without heated bed. No chemical odors produced during printing
