A PLA filament
Poly-Lactic Acid (PLA) is a thermoplastic which is derived from plant-based starches and is biodegradable under the right conditions. It is a strong and stiff material suitable for many uses. It has a lower heat tolerance and less impact resistance than an ABS filament, but it adheres well to itself and all surfaces. It can be sanded, glued, and is receptive of most paint products. It's available in many colors and recognized for its shiny surface.
The average temperature for 3D extrusion should be around 180-200 degrees Celsius. Different colors may need to be adjusted with slightly different extrusion temperatures.
It has a low warp tendency and doesn't require a heat bed. If a heated bed is utilized, a temperature of 60 degrees Celsius is recommended. Printing on a blue painters tape will help in keeping the print adhered.
PLA should be used in a well-ventilated area. It releases a sweet smelling odor when it is at melting point.
