Polylactic acid or polylactide (PLA) is a thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States), tapioca roots, chips or starch (mostly in Asia), or sugarcane (in the rest of the world). It is a common type of plastic filament used in reprap-based 3D printers, such as the Solidoodle. 
PLA can come in many colors, such as Transparent, Natural Off-white, Black, Blue, Green, Orange, and even Glow-In-The-Dark formulas. It's shinier than ABS and breaks easier. PLA filament is often a bit translucent.
Common filament diameters are 3mm and 1.75mm. The Solidoodle and most other similar 3d printers use 1.75mm PLA filament.
 Printing with PLA
PLA is relatively easy to print with and can be printed without a heated bed and at lower temperatures than ABS. It sticks well on kapton tape or blue painters tape. Sometimes it sticks a bit too well and might be hard to remove from the print bed.
