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 Dreamer 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 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,
which is suitable for the beginners, 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
Dreamer User Guide | www.FlashForge.com
400- 699-1063
· 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 Dreamer.
Using FlashPrint, you can prepare .stl files to be .g or .gx files for printing. Then the
files can be transferred to your Dreamer via USB cable, USB stick or WiFi.
1.1.3 Build the 3D Model
Once the output file has been transferred to your Dreamer, it will start to turn the 3D
model into a physical object by laying down layers of filament.

Chapter 5: Build Plate Leveling
A correctly leveled build plate is almost a guarantee for a high-quality 3D object.
When there is something wrong with the printed objects, you should check whether
the build plate is leveled or not firstly. A general rule of thumb is to leave a gap with
the thickness of a piece of paper. However, for printing finer objects (150 micron and
lower), please use a feeler gauge to level the build plate as it requires a lesser gap
between the nozzle and the build plate.
The Dreamer utilizes a three-point leveling system for its build plate. At the bottom of
the build plate, there is one spring-loaded knob in the front and two in the back.
Tightening the screw will create a bigger gap between the build plate and the nozzle
while loosening it will create lesser gap.
1. (5-1)From the main menu, tap [Tool]-[Level]. The extruder and the build plate
will begin to move to the starting position.
Dreamer User Guide | www.FlashForge.com
400- 699-1063
2. (5-2)Take out the leveling card (Leveling video can be acquired by scanning the
QR Code)
3. ( 5-3 ) Once the extruder and build plate stop moving, slide the piece of paper
continuously back and forth between the nozzle and the build plate. And
simultaneously adjust the knob until the paper causes a slight friction.
4. (5-4)Tap [NEXT] and wait for the extruder to move to the second position. Slide
the paper back and forth again, and adjust the screw to create the same amount of
friction as the previous step.
Dreamer User Guide | www.FlashForge.com
400- 699-1063
5. (5-5)Tap [NEXT] again and repeat the same leveling process.
6. (5-6)Tap [NEXT]. The nozzle will move to the center of the build plate. Slide the
paper through to make sure there is a slight friction. Slowly adjust all the screws by
the same amount if there is no friction or too much friction.
7. (5-7)Tap [FINISH] once you have finished this.

Dreamer User Guide | www.FlashForge.com
400- 699-1063
a. Top Solid Layer: Maximum is 30, minimum is 1.
b. Bottom Solid Layer: Maximum is 30, minimum is 1.
● Infill
a. Fill Density means fill rate.
b. Fill Pattern is the pattern of filling shape which effects printing duration.
c. Combine Infill: You can select the layers for combining according to the layer
thickness. The combined thickness should not exceed 0.4mm. “Every N layers” is for
all the infills while “Every N inner layers” is only for inner infills, which generally
can save print time.
● Speed
a. Print Speed is the moving speed of the extruder. Generally, the lower speed
is, the better print you will get. For PLA printing, 60 is recommended.
b. Travel Speed is to control the moving speed of the extruder under
non-printing status during work. For PLA printing, 80 is recommended.
Note: Modify parameters settings to get better prints as different models need
different parameters.
● Temperature
Right Extruder Temperature: Recommended extruder temperature is 220℃.
Note: Different temperatures have subtle influences in printing. Please adjust the
temperature according to the condition in order to get a good print.
Platform Temperature: To set the temperature of Platform.

● Others
Cooling Fan Control: Set up the time to turn on the cooling fan. You can pre-set
the height and make the cooling fan begin to work at the point.
Pause At Heights: Allow users to pre-set a height in which the print will
suspend automatically. The function usually applied when you want to change the
filament at a certain point.
(5-7) Click[Edit], then you can add or remove a height.
