Figure 1.. Macrograph image and scanning electron microscopy micrographs of 3D-printed PLGA/β-TCP/Mg composite porous scaffolds. (A) Macroscopic image of a fabricated scaffold. (B-D) Transverse section at a magnification of PT10M scaffold by SEM (original magnifications 30×, 500×, and 1000×). Scale bars: 500 μm in B, 10 μm in C, and D. 3D: three-dimensional; Mg: magnesium; PT10M: PLGA/β-TCP/10 wt% Mg porous composite scaffolds; PLGA: poly(lactic-co-glycolic acid); β-TCP: beta-tricalcium phosphate.
