Preface
On the completion of this User Guide, thanks all FlashForge engineers and the
FlashForge 3D printer users for their unremitting efforts and sincere assistance.
The FlashForge Hunter User Guide is designed for the Hunter users to start their
printing journey with FlashForge Hunter. Even if you are familiar with earlier
FlashForge machines or 3D printing technology, we still recommend that you read
through this guide, as there is lots of important information about the Hunter for you to
get a better 3D experience.
For a better and more successful printing experience, you can refer to the following
materials:
(1) Quick Start Guide
Users will find the Quick Start Guide together with the printer accessories. The Quick
Start Guide will help you start your print journey as soon as possible.
(2) Official FlashForge Website: http://www.FlashForge.com
The official FlashForge website contains the up-to-date information concerning
FlashForge software, firmware, device maintenance and so on. Users are also able to
get the contact information from there.

Chapter 1: 3D Printing Technology
Digital Light Processing (DLP) is a new method of 3D printing. It is also the
method that the Hunter uses. It works by first digitally processing the image signal,
and then projecting the light to the photosensitive resin van to get a solid model
according to the irradiation projection.
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 of 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 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. FlashDLPrint is the slicing software used for the
FlashForge Hunter.
Using FlashDLPrint, you can prepare files to be SVGX files for printing. Then the
files can be transferred to your Hunter via USB cable, USB stick or Wi-Fi.
