STUDY ON SHAPE MEMORY EFFECT OF 3D-PRINTED PLA
Keywords:
shape memory polymers (SMP), 3D printing, FDM technologyAbstract
Shape memory polymers belong to a group of smart materials, which are able to return to its original shape triggered by physical stimulus. In recent years 4D printing name has started to be used, which involves printing of 3D models that change their
shape in time. The test samples were made of polylactide (PLA) with shape memory by using the FDM 3D printer. Half of the samples were immersed in PBS solution. Bending test was conducted. The thesis analyses the results of how exposure to PBS affects the properties of shape memory PLA
