PLA (polylactic acid) is made from cornstarch and is an environmentally friendly material to print with as it can be compostable depending on the amount and types of additives (pigment, mixing of other plastics or fibers) added to the natural PLA. PLA emits no fumes when printing in the temperature range of 180-220C. Going above 220C, the material will begin to carbonize at around 250C and clog the nozzle.
PLA is recommended for beginner users as it prints well without hassle and does not curl or warp after printing. It can also be primed and painted if creating a usable prototype or a fit and feel model. Most users use PLA as a benchmark material when comparing materials.
PLA has a range of temperatures depending on the purity and colour of the PLA filament. A natural PLA can print at 180C while a white or highly pigmented PLA will print as high as 220C. We recommend a bed temperature of 50C. Using 3d LAC as the bed adhesive will aid the parts' adhesion to the bed while printing.
Storage: store with desiccant as PLA will absorb water and can become extremely brittle after long exposure in a humid environment. This can be noticed when printing with old PLA where the drive gear teeth wear it down within the first few hours of printing instead of gripping the filament and feeding through the extruder.
