Background: two series of poly(lactic-co-glycolic) copolymers were synthesized
at three different concentrations 70:30 wt.%, 80:20 wt.% and 90:10 wt.% (AL: AG)
under high vacuum (Schlenck techniques). The materials were characterized by
Differential Scanning Calorimetry (DSC), Infrared Spectroscopy with Fourier
Transform (FT-IR), X-Ray Diffraction (XRD) and MALDI-TOFF mass spectrometry.
The copolymers were used in a 3D printer to print biopolymeric stents of
different concentrations which it was designed with SOLIDWORKS 2016
software. The stent was design a cylindrical mesh structure of 3.47mm with an
internal diameter of 9mm, an external diameter of 15mm and a thickness of
3mm. Mechanical properties were measured to the stents structures to evaluate
their possible behavior within the arteries
