Factor

Parameter

Instructions

Model size

10 mm × 10 mm × 5 mm

Dimensions of the scaffold design.

Filling mode

Linear filling 0.26 mm

Pattern used for internal structure (spacing: 0.26 mm).

Nozzle

0.15 mm 1.1 mm

Diameter of the printing nozzle.

Layer height

Room temperature

Vertical thickness of each printed layer.

Platform temperature

− 12 to – 40 °C

Temperature range of the printing platform (adjusted layer-by-layer).

Nozzle temperature

0.2–0.25 MPa

Temperature of the nozzle during extrusion.

Printing speed

10 mm/s

Speed of the nozzle movement during printing.

Air pressure

10 mm × 10 mm × 5 mm

Pressure applied to extrude the material through the nozzle.

  1. *Platform temperature was initially set to -12 °C for the first 4 layers and manually reduced as printing progressed.
  2. *Air pressure was adjusted dynamically based on remaining material in the cartridge.
