Figure 5. Vector drawing for 2D bioprinting applications. (A) A simple meandering pattern. (B) The outline of a heart drawn and printed. (C) The
outline of the department logo. The drawn blue part is extruded while the red line is the unextruded print path. (D) A pattern printed with two different
materials. The colors of the paths correspond to the different materials used, with additional travel paths drawn from the origin for each of the sections.
The magnified inset shows the interface of the two materials with increased contrast, offering a clearer view of the transition. (E) A 2D heart shape with
the red infill mimicking different tissue directions and connecting paths between the sections drawn in green. (F) The institute logo with a drawn infill
pattern, printed with two materials, with the unextruded connecting path drawn in red. (G) A concentrically arranged pattern with an additional 15 × 300
µm polycaprolactone (PCL) fibers aligned during printing.
