Figure 2.

(A-D) Adaptive manufacturing of different geometries such as tessellated arrays of squares with heights up to 400 µm (A-B), rectangles with dimensions of 300 µm x 1200 µm (C), and isosceles triangles (D). (E) Fiber stacks consist of interwoven fibers which are layered on top of one another. A high level of precision in fiber placement is revealed at the intersections of fiber stacks. (F) Non-regular arrays of shapes with characteristic features in the range of 100 µm. (G-H) Fiber diameters ranged from 50 µm (G) to 6 µm (H). (I) SEM image of a representative portion of a structure used to determine the parallelism, perpendicularity, and geometric consistency of the PLGA fiber stacks patterned by 3D jet writing. Error reported is the average root mean square error of the three scaffolds measured. Scale bars represent 1 mm (A), 500 µm (B, D, I), 100 µm (C, F), 50 µm (E, G-H).
