text: " Poly(lactic acid) (PLA) belongs to the 3D printable materials
which show shape-memory properties, i.e., which can recover their original shape
after a deformation if they are heated above the glass transition temperature.
This makes PLA quite an interesting material for diverse applications, such as
bumpers, safety equipment for sports, etc. After investigating the influence of
the infill design and degree, as well as the pressure orientation on the recovery
properties of 3D printed PLA cubes in previous studies, here we report on differences
between different PLA materials as well as on the impact of post-treatments after
3D printing by solvents or by heat. Our results show not only large differences
between materials from different producers, but also a material-dependent impact
of the post treatments. Generally, it is possible to tailor the mechanical and
recovery properties of 3D printed PLA parts by choosing the proper material in
combination with a chemical or temperature post-treatment.\r\n "
