--- _id: '1590' abstract: - lang: eng 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 " article_number: '71' article_type: original author: - first_name: Guido full_name: Ehrmann, Guido last_name: Ehrmann - first_name: Bennet full_name: Brockhagen, Bennet last_name: Brockhagen - first_name: Andrea full_name: Ehrmann, Andrea id: '223776' last_name: Ehrmann orcid: 0000-0003-0695-3905 orcid_put_code_url: https://api.orcid.org/v2.0/0000-0003-0695-3905/work/105572294 citation: alphadin: 'Ehrmann, Guido ; Brockhagen, Bennet ; Ehrmann, Andrea: Shape-Memory Properties of 3D Printed Cubes from Diverse PLA Materials with Different Post-Treatments.
