PLA

PLA is probably the easiest material to work with when you first
start printing. PLA is a biodegradable thermoplastic that has been
derived from renewable resources such as corn starch and sugar
canes. This makes PLA environmentally friendly and very safe to
work with.
PLA also has a very sharp glass transition point so if you use
a fan to cool it, on printing it will set to solid very quickly. This
has the advantage of achieving a greater range of geometries
than are possible with other plastics. It also reduces the
thermal stress on the printed part — warping becomes
less of an issue in larger parts when you print with PLA.
It is important to point out that although PLA will degrade in an
exposed natural environment it is very robust when used in any
normal application such as a printed toy or a critical piece of a
printer. In that respect you can think of it as being similar to iron. If
you were to expose it to continuous moisture or leave it outside, it
would "rust" and become unusable in short order. But if you had it
in your home you would expect it to last nearly indefinitely.
Compared to ABS, PLA demonstrates much less part warping and
curling and, for this reason, can be successfully printed without a
heated build plate.
Details such as sharp corners and edges print well and PLA printed
objects will generally have a glossier look and feel, easy to print in
different layer thickness range (0,02-0,75)
Here is table with approximate printing temperatures. We
encourage you to expierement with temperatures and find what
fits you the best.
Also you can check filament manufacturer home page for
suggested temperatures for exact material.
Enjoy printing!
