Pluronic is a sacrificial bioink that can be used for temporary support or to create channels, vessels or vasculature for 3D bioprinting purposes. The recommended preparation provided in the user instruction below yields a streamlined printable biomaterial that supports 3D printed cellular constructs. However, preparation can be modified by users to suit their needs. This protocol will walk you through the step-by-step instructions for bioprinting pluronic.
Storage & Handling
Methods for Bioprinting Pluronic
- Attach a syringe cap to the tip of your syringe. Remove the plunger.
- Remove Pluronic F127 from storage and pour (while still cool) into syringe.
- Note: Pluronic should be stored at 4˚C until ready for use.
- Place the stopper back into the loaded syringe.
- Allow syringe filled with Pluronic F127 to warm to room temperature.
- Remove syringe cap and attach a plastic printing tip.
- Note: Read the Guide to Picking a Bioprinting Needle Protocol to help decide which needle gauge to use for your chosen application.
- Print construct using the print settings outlined in the table below.
- To remove Pluronic F127 from printed construct, cool entire construct to 4°C over ice. Use a vacuum if necessary to remove material.
|Speed (mm/s)||Layer Height (mm)||Nozzle Diameter (mm)||Gauge||Pressure||Print Temp(C)|
|6-10||0.2||0.2*||0.25″ straight 30G||80||Room temperature|
|7||0.2||0.2*||1.25″ conical plastic 27G||15||Room temperature|
*Note that the nozzle diameter print setting for this material is slightly larger than the diameter of the recommended gauge (150 μm).

- A fill volume change of more than 2 ml may affect pressure settings.
- A lower gauge size or tapered gauge will require a lower pressure, while a higher gauge will require higher pressure for extrusion. Lowering the gauge size will also generally lower resolution.
