3D-Printed Polylactic Acid Scaffold for Regenerative Implant Integration Applications

摘要

3DHC patterns at 0°; 90° angle excelled in all three mechanical criteria investigated and demonstrated the optimal pore geometry and structure for tissue integration. With a high flexural modulus, the 3DHC scaffold retained its shape better than its counterparts. 0.2% yield strength for the 3DHC pattern at 0°; 90° was 21% higher than other patterns, which helps the scaffold retain its structure, enabling its use in loadbearing tissues and implants. A 3DHC scaffold with 75% porosity can be printed with pores that measure within the desired 400-1200 um range , 3DHC patterns at 0°; 90° were also found to have pore qualities at par with RTL patterns; however, they provide superior mechanical properties and better chances when used with load-bearing tissue.
