Review of current state of biocomposite materials with polylactic acid (PLA) base used in additive manufacturing

Additive manufacturing (3D printing), particularly Fused Filament Fabrication method,
is a technology that uses polymer materials with melting properties to produce physical
objects. Environmental concerns have the aim to reduce all kinds of nondegradable plastic
materials, thus lots of scientific research is done to create new composite materials with
improved properties. This research was carried out with the aim of categorizing and summarizing
the current state of fillers used in biocomposite materials with the base of polylactic
acid (PLA) polymer. The use of organic materials as a source for the production of
polymers has been used in the market for a long time. Small amounts of organic materials
have already been successfully used as polymer fillers. In this way, a more cost-effective
and sustainable filament materials are created. By mixing the various amounts of fillers
with commercially available filaments, the potential of sustainable filament is evaluated
and compared its’ properties and printability.
