Introduction
3D Printing is a revolutionary emerging technology that will change the way we undertaken design and manufacturing and with profound geopolitical, economic, social, demographic, environmental, and security implications.
The 3D Printing Process begins with a 3D model of the object, usually created by computer-aided design (CAD) software. Specialized software slices this model into cross sectional layers, creating a computer file that is sent to the 3D printing machine. The 3D printer then creates the object by forming each layer via the selective placement (or forming) of material.

-
Double click the file 3D printer desktop icon. Now printer tool kit main user interface will be opened.
-
Select COM 4 or Higher COM number (ie., COM 5 or 6 or … 9)
-
Click Connect to printer, when Green light glows it shows you are connected to 3D Printer. Set target temperature 180 degree Celsius.
-
-
-
Set 'Extruder Speed' to 1000 ['Print' tab] - and 'Length' to 800, set the printer XY speed to 1000 [Printer Settings' button on print option tab]
-
Wait for heat to meet 180 - before trying to turn the extruder "Run Extruder" button' NEVER RUN THE EXTRUDER BELOW 180'
-
Adjust heat and or speed up by 10 steps. Eg: Heat up to 190' if still not flowing well then turn up again by 10' and increase 'Extruder Speed' by10 repeat this/fine tune this until the plastic flows straight & does not curled.

-
Do not try to print anything until the plastic flows straight.in the homing position. The analogy is this:- If you turn a water tap on too much eg. The extruder driver 'speed' to fast, than the plastic/just like water flowing too fast out of a tap, will spray wildly / curl.
-
Also the plastic filament driver, if pushing/turning too hard/ fast on the filament- will become a grinding wheel- tearing strips off the filament- which will lead to a loss of filament driver traction. Resulting in the extruder stopping to extrude plastic. Always start with these low settings- before venturing to faster settings.

-
For nozzle size 0.4mm use a layer height of about 2/3 eg 0.25 to 0.3mm.
-
Once the plastic flows straight, measure the output of plastic in say 5 seconds. Repeat this and obtain an average extrusion length eg 90, 105, 100 = 295/3 - 98.33mm/5 seconds.
-
Adjust xy- to be travel the same distance eg 98.3mm over 5 seconds. This established a ratio between the plastic extrusion length and the distance traveled by x or y. eg extruder 'speed' 1200' xy 900mm/minute (this number will vary with the extrusion plastic used).
-
-
-
Once you have established a ratio between extrusion length and xy travel, you can double it or half it to obtain different print speeds.
-
Now that the plastic is flowing straight in the home position, press the 'Print' button. Press this button whilst the extruder test is still producing a good plastic flow. This will prime the print head to be ready for printing.

LOADING YOUR DRAWING: The drawing file must be in STL format (file extension .stl) First click the 'Input file' Tab
-
Click Load STL for new window to open. You can now load any of your STL format designs from your drawing folders.(*.stl) Click Ok after selecting your file.
-
Now your design file is loaded
