Chapter 1: 3D Printing Technology
3D printing refers to transforming three-dimensional models into physical
objects that you can hold and touch. It is also called additive manufacturing
because the 3D model is created by “adding”layers upon layers of material
until the object is fully formed.
Fused Filament Fabrication (FFF) is the most common method of 3D printing.
It is also the method that the Guider IIS series uses. It works by melting
plastic material called filament onto a print surface in high temperature. The
filament solidifies after it cools down, which happens instantaneously after it is
extruded from the nozzle. 3D objects are formed with the filament laying down
multiple layers.
1.1 Process
3D printing involves three steps:
1.) Make or download a 3D model
2.) Slice and export the 3D model
3.) Build the 3D model
1.1.1 Make a 3D Model:
Currently, there are three ways to creating a 3D model.
·Designing From Scratch You can use free CAD (computer-aided design)
software such as 3DTADA, AutoCAD, SolidWorks, Pro-E, and our own
software Happy 3D to design your own 3D model.
·3D Scanners An alternative method to creating a 3D model is to scan an
object. 3D scanners work by digitizing a physical object, collecting its
geometric data, and saving it to a file on your PC. There are also apps that can

Guider IIS series User Guide | www.flashforge.com
turn a mobile device into a 3D scanner.
·From the Cloud The most popular way of obtaining a 3D model is to
download it from websites that allow users to upload 3D models that they
designed.E.g. : www. thingiverse.com
1.1.2 Slice and Export the 3D Model:
Slice software is the software that prepares 3D models for printing and turns
them into instructions for the 3D printers. FlashPrint is the slicing software
used for the FlashForge Guider IIS series.
Using FlashPrint, you can turn .stl files into .g or .gx files for printing. Then the
files can be transferred to your Guider IIS series printers via USB cable, USB
stick ,Wi-Fi or Ethernet cable.
GuiderIIS series device support Simplify3D software, software not developed
by FlashForge may need register or charge extra fee, please choose to use(or
not) according to your needs.
1.1.3 Build the 3D Model:
Once the output file has been transferred to your Guider IIS, it will start to turn
the 3D model into a physical object by laying down layers of filament.
