摘要
The present invention relates to an integrated Assisting Cooling (AC) device, system and method for use with PED devices, allowing use of biopolymers having higher melting points in the fabrication of 3D scaffolds. The AC device cools the filament as it is extruding from the nozzle via low flow convective cooling. The AC device allows for cooling in the +/− direction of motion on an XY plane. The AC device elevates with the material delivery chamber. The AC device allows for scaffold fabrication at applied temperatures as high as about 250° C.
