Polylactic acid or Filamento PLA is a thermopolymer produced by fermentation of maize, it is not biodegradable under natural conditions but is water-soluble at temperatures above 70-80° C. It can be extruded, injection molded and blow molded and currently it is mainly used to produce containers of various types and plastic bags.
T° of printing 200-220
T° of plate 50-70
Printing speed 40-80mm/s
Fan speed 50-100%
Density 1.24 g / cm ^ 3
The filament arrives without a coil so before starting to print it will be necessary to print a MasterSpool like this one:

The tests at the end of the page were performed with the following printer:
