CellStruder v1

thingiverse

CellStruder, a NEMA stepper motor-powered syringe extruder, precisely dispenses liquids at the microliter level in a 20mL capacity. Developed at Rice University's Tabor Lab for cell printing, this device advances research in synthetic biology, biological pattern formation, and engineered cellular logic. A print of E. coli cells expressing green fluorescent protein is displayed alongside microscopy images of printed cells. To assemble, print all parts and source the BOM materials; attach the NEMA motor to the motor plate with screws, fit the coupler and threaded rod, secure side rails, insert the linear bearing, and fasten the back plate. Slide in the 8mm linear rod for assembly cohesion, then place the syringe in position with two screws. This versatile tool can print any liquid or viscous gel; it was initially designed to print E. coli in defined patterns for research on synthetic biology and pattern formation engineering. Fluorescence microscopy reveals an example print of E. Coli cells expressing green fluorescent protein, accompanied by a petri dish inscribed with "NSF EFRI," the grant supporting this research.
