Abstract: Disclosed is a bioextruder assembly capable of “retro-fit” an existing three-dimensional (3D) printer such that it is capable of printing biomaterials. The bioextruder assembly may be modular, self-contained, and configured as “plug-and-play” unit. In some embodiments, the bioextruder assembly may be configured for use in zero-gravity environments such as space and configured to engage with existing 3D printers in space. In some embodiments the bioextruder assembly includes an extruder configured to extrude bio-materials stored in a syringe that is coupled to the extruder, and a converter. The converter may include an electromechanical coupling component that couples the converter to a three-dimensional printer system, and a motor configured to actuate the extrusion of bio-materials stored in the syringe based on signals received from the three-dimensional printing system via the electromechanical coupling component. In some embodiments, the converter may be configured to reversibly attach to the extruder via an attachment element.
