The solidifying polymer melt was collected into a water bath as filament 1.75 mm in diameter thus, the postprocessing usually used for filaments fabrication via extrusion was overcome. During printing, a single tool head extruder with a 0.25 mm diameter was employed to melt and deposit the copolymers according to the desired pattern onto a poly(etherimide) (PEI) sheet print surface, adjustable within a temperature range of 20-120°C. Initially, a porous tubular design, resembling a coronary artery with a 5mm inner diameter and 0.5mm wall thickness, was created using Fusion 360 software. Various pore shapes (circular, elliptic, rectangular, and hexagonal) and sizes (ranging from 0.25mm to 1mm) were systematically evaluated, with the hexagonal pore design at a size of 0.8mm identified as the optimal choice due to its superior performance during printing. The selected design was 3D printed using FFF, with optimized printer parameters, including extrusion temperature, bed temperature, flow rate, and printing speed, to ensure precise replication of the tubular structure. The design was converted into a .stl file, and the printing process was programmed layer by layer using Repetier-Host Software, with adjustable parameters such as extrusion temperature, flow rate, and printing speed, controlled throughout the process.
