08 Frequently asked questions
• What do the LED colors indicate?
The printhead LED will change depending on its status. When the printhead is first mounted,
the light will turn white to indicate that it is initializing. Once it is recognized, the LED will turn
blue. Blue light also indicates a temperature below 35 degrees Celsius. When the temperature
of the printhead is between 35 and 50 degrees, the light turns yellow to indicate that the
printhead is warm. When the printhead is above 50 degrees, the light will turn red to indicate
that the printhead is hot.
• Can I use multiple printheads and printhead types simultaneously?
You can use multiple printheads within the same printing protocol to generate multimaterial
constructs. You can’t print simultaneously because the pressure can only be provided to one
printhead at a time.
• What is the mechanism that enables bioprinting with this printhead?
This printhead leverages compressed air to actuate a plunger in the cartridge to compress
the melted thermoplastic. This causes the material to be extruded through the nozzle. The
extrusion rate is proportional to the applied pressure, viscosity of the melted thermoplastic
and the nozzle diameter.
• My thermoplastic is not extruding.
This could happen for several reasons. The cartridge may be empty, the nozzle may be blocked,
the plunger may be stuck, the bioink may not have melted completely or the pressure applied
may be insufficient.
