(PLA) is a biodegradable polymer material. Its raw
material is from wheat, corn, tapioca roots, potatoes, or sugarcane. PLA is recyclable and compostable material. In some commercial
compost sites, they do composite for PLA. It is a petroleum-free and
eco friendly plastic material. The other great feature of PLA
filament is that it doesn’t release fumes when printing it’s
relatively safer in the classroom and office.
PLA is soluble in chlorinated solvents, hot benzene, tetrahydrofuran,
and dioxane. PLA has similar mechanical properties to PETE polymer,
but has a significantly lower maximum continuous use temperature.
PLA is the ideal material for a 3D
printer. It is dimensionally stable, so there is no need for a
heated bed. PLA has a slightly higher coefficient of friction in the
drive and transport than ABS, but it has lower viscosity when
molten. This means lower pressure in the melt chamber and hence a
lower driving force.
PLA is basically for consumer products, small toys, higher print
speeds, smoother layers. It has good strength, durability, and some
impact resistance, but it can deform when getting too hot. PLA has
limited flexibility, slightly brittle and less sturdy than ABS. Once
temperature, bed height and speed are set, it is not difficulty to
