3D Printing Process.
We need to follow some procedure in order to 3D print. Always start with 3D CAD model. 3 Dimensional model on computer of the object you want to print. From there you export that model as a dot stl (.stl) file (stereolithography file). And from there you can import into a slicing software whereby you edit layer, tool path, temperature, color, how fast you want to print etc. Next to send the code that the slicer makes in a dot gcode file of the 3D printer. Click print and wait for the 3D print object out.
