Other Notes
- Optimize printing conditions (e.g., nozzle diameter, printing speed, printing pressure, temperature, cell density) for the features of your 3D printer and your application.
- Reduce bubble formation. Air bubbles in bioink may hamper bioprinting. Carefully handle the bioink when you mix and transfer it to avoid bubble formation. Do not vortex or shake vigorously.
- UV light Crosslinking. Position the light source directly above the printed structure. Lower intensity light sources will require shorter distances and longer exposure times to complete crosslinking. Recommended conditions: Place an 800 mW/cm2 light source 8 cm above the printed structure and expose for 30 s.
Procedure
1. Prepare bioink solution: Warm TissueFab® - GelMA-UV bioink in a water bath or incubator set to 37 °C for 30 minutes or until the bioink becomes fluid. Gently invert the bioink to make a homogeneous solution. DO NOT vortex or shake vigorously.
2. Prepare bioink-cell solution: Resuspend the cell pellet at the desired cell density with the bioink solution by gently pipetting up and down. Typical cell density for extrusion-based bioprinting is 1 to 5 x 106 cells/mL. Load the bioink-cell solution into the desired printer cartridge.
3. Bioprint: Cool the filled printing cartridge to 15–19 °C to induce gelation, using a temperature controlled printhead or place the cartridge in at 4 °C for 10–15 minutes. If print bed temperature control is available, set temperature to 15 °C. Follow the 3D printer manufacturer′s instructions. Load the print cartridge onto the 3D printer and print directly onto a Petri dish or into multi-well plates. Adjust the flow according to nozzle diameter, printing speed, printing pressure, and temperature.
4. Crosslink: Place the UV light source directly above the 3D-bioprinted structure and expose the structure to UV light (wavelength 365 nm). Use the appropriate distance settings and exposure times for your bioprinter.
5. Culture cells: Culture the bioprinted tissue with appropriate cell culture medium following standard tissue culture procedures.
