Fig. 4From: In-vitro evaluation of Polylactic acid (PLA) manufactured by fused deposition modelingScanning electron microscopy revealed that PLA disks and Titan control were homogenously covered with regularly spread osteoblasts. Cells were regularly shaped and showed spread filopodia connected to the sample surfaces. PLA samples (a) 1 mm (b) 300 μm (c) 50 μm magnification; Titan control (d) 1 mm (e) 300 μm (f) 50 μm magnificationBack to article page
