Printing Techniques
Ensure accurate nozzle height. If the nozzle height value is too
low, it will cause warping; if it is too high, it will crash the nozzle
into the platform, causing damage and clogging. You can
manually fine-tune the nozzle height value in the "Calibation"
panels. You can try to adjust the nozzle height value plus or
minus 0.1 –0.2mm from the base on previous re- sults.
Calibrate the printing platform well. An unleveled platform usu-
ally causes warping.
Allow enough time for sufficient pre-heating. Please use the
3D Print – Preheat function. A well preheat- ed platform is
essential for printing large objects without warping.
The airflow on print head is adjustable, turn the air flow adjust-
ment knob to change the amount of cooling of printed object.
When printing in PLA, turn the lever counterclockwise to
direct the airflow to the nozzle. This will cool the PLA as soon
as it is extrud- ed and improve print quality. When printing
large object using ABS, turn the lever clockwise to direct the
airflow away from nozzle to slow down the cool- ing and to
prevent warping. Users could experiment with different
amount of cooling to achieve optimal result.
Printing with no raft. It is highly recommended to use raft for
normal printing as it improves adhesion and is required for
leveling compensation. It is turned on by default, but you can
turn it off in the "Print Pre- view" panel if you desire to.
Printing with no support. It is possible to print with- out sup-
porting structures. You can turn off support
