Photograph of BariCUDA extruder with schematic representations of heating and PCL components superimposed. Nitrogen gas is used to pneumatically control extrusion through a syringe-based extruder. Nichrome wire acts as a heating element around the entire surface of the syringe and melts the PCL pellets for facilitated extrusion. No solvents are needed for polymer extrusion in this system.
