3. Cura software parameter settings

Open Cura software,you can modify all of the printing parameters on the display screen.


Select "Switch to full settings".








Layer height: 0.1 - 0.4mm available. 0.1mm high precision, but long printing time, 0.4mm low precision, but printing time is too short, in general select 0.2mm.


Shell thickness: 0.4mm is very thin, in general select 1.2mm, that will increase the printing time.


Enable retraction: To prevent the wire from leaking when printing quickly, otherwise it will affect the appearance.


Bottom / Top thickness: In order to make the top layer print more perfect and flat bottom layer.


Fill density: If the intensity is not high, select 20%. If the intensity is high, increase it and the printing time also will increase.


Print speed: Generally set 30-100, he print speed is higher and the precision is lower.


Printing temperature: Depends on the filament, generally select 190 - 210 degrees.


Support type: Include a half-support and full support. In general the model with suspended structure needs to set support, but a surface will be rough after removing support.


Platform adhesion type: "None" means do not set any support, "Brim" increases the bottom area. "Raft" base makes the model more adherent. To make the model better adhere to the base, add a base or edge. But best to increase a base and an edge relative to the small bottom area.


Diameter: 1.75mm


Flow: 100%




Nozzle size: 0.4mm.


Retraction Speed: The speed of retraction when printing.


Retraction distance: The length of material retraction, generally select 4.5 - 8mm.


Initial layer thickness: The first layer thickness of printing. Select default option.


Initial layer line width: 100% will be thicker and denser, Select default option.


Cut off object bottom: The length of cutting off the bottom of model.


Dual extrusion overlap: 0.15mm. Select default option.


Travel speed: The moving speed when nozzle does not extrude filament.


Bottom layer speed: The speed of printing the first layer. Setting a slower speed to make object better attached to base plate.


Infill speed, Top / bottom speed, Outer shell speed, Inner Shell speed: Select default option.


Minimal layer time: Select default option.


Enable cooling fan: To cool the temperature of nozzle.
