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 InventorⅡ 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 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.
InventorⅡ User Guide | www.flashforge.com
0086-0579-82273989
·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 InventorⅡ.
Using FlashPrint, you can prepare stl. files to be g. or gx. files for printing. Then the
files can be transferred to your InventorⅡ via USB cable, USB stick or Wi-Fi.
1.1.3 Build the 3D Model:
Once the output file has been transferred to your InventorⅡ, it will start to turn the 3D
model into a physical object by laying down layers of filament.

Leveling Emergency Plan：
Some leveling spare parts may be damaged after being used for a period of time.
Now users could adopt the emergency plan for leveling.
（1）Insert the USB stick to the USB port.
（2）Tighten each of the three knobs underneath the build platform until they go no
further
（3）Tap [Build] on the touch screen, tap the USB icon and then select Leveling.g
file.
（4）Tap [Build], then the build plate and the extruder start moving.
（5）After they stop moving, you can adjust the distance between the build plate and
the nozzle manually. Move the extruder to the position right over the front-left knob,
and adjust the knob individually. Use a A4 paper to check the distance. As you adjust
the knob, make sure the paper just slides between the nozzle and build plate. There
will be somewhat friction on the paper but still can easily pass the paper between the
plate and the nozzle without tearing or damaging the paper.
（6）Then move to the positions right over the right-front and rear knobs successively,
and then adjust the distance according to the descriptions above.
（7）Then move to the center of the build plate for a check. Confirm that the paper
slides between the nozzle and build with a moderate amount friction.

7.1 Skills on Supports
(Reference Video：Skills on Supports)
Support structures enable the printing of models with steep overhangs and cantilevered
sections. The InventorⅡ 3D printer utilizes Fused Filament Fabrication (FFF)
technology, which works on the additive manufacturing principle of heating and laying
down material layer by layer to create an object. Many sophisticated 3D print designs
require materials to be deposited on a layer where there was not a previous layer, or
the designs have steep angles which might cause undesired drooping during the print.
In these cases, support structures are needed to ensure objects integrity and print
quality.
①Principle of 45 Degrees
Generally speaking, if the 3D model has an overhang of more than 45 degrees, you
InventorⅡ User Guide | www.flashforge.com
67
0086-0579-82273989
will need supports. This angle is determined by the material, layer height, extrusion
width, and temperature. It is critical to adjust the support structures accordingly to
ensure the best print result, especially for large 3D prints.The principle is raised by a
stage designer and widely accepted among the 3D printing industry.
②Principle of Proportionality
As for the application of supports, users are suggested to comply with the principle of
proportionality. Even though the supports algorithm has been developing, adding
supports intelligently cannot be realized at present. Therefore, users are always
oriented in adding the supports. As we all know, excessive supports will definitely
result in difficulty in supports removal, while limited supports cannot ensure the
stability of the model. Since FashPrint has the function of manual modification, users
can add proper supports to their models according to the daily experience and the
academic principles.
●Support Types
Linear Support Structure：Suitable for models with large-area overhang(s).
Features：Full coverage of supports improves the model stability. But the supports on
the surface are difficult to be removed and will definitely reduce the print quality.
Treelike Support Structure：Suitable for models with small area overhang(s).(You
are suggested printing a raft)
Features：Treelike support structure is proprietary to Flashforge Corporation. And this
structure can save support material and can be easily removed. However, compared
with the linear support structure, it’s of less stability. So you are suggested to manually
add more supports after auto-generating treelike supports.

needed. Press down the left mouse button and drag to generate the support.
2）Manual Delete
7-11
Like the picture above, a hole inside the model doesn’t need any supports.
Left click the [Delete] button and then left click the supports needed deleting. And the
support will be deleted.
7.2 Control over Printing Quality
① Enhance the build plate adhesiveness
● Leveling the build plate
● Keeping the build plate smooth and tidy
● Using the build tape or glue
② Adjusting the printing speed
● Low (Fast) (Print Speed 80mm/s Travel Speed 100mm/s)
● Standard (Print Speed 60mm/s Travel Speed 80mm/s)
● High (Slow) (Print Speed 50mm/s Travel Speed 70mm/s)
● Hyper (Print Speed 50mm/s Travel Speed 70mm/s)
7.3 Skills of Model Placement
Not all the models are in the right positions after being loaded. Therefore, you need to

place it in an appropriate position for better print quality. Such as the models below,
you need to put one of the surfaces onto the platform.(Please refer to 5.1.12-⑦Surface

Left-click on the model to select it and double-click on the Cut icon to set the cut
plane. The direction and position are available for setting.
E.g：
As for a big model or an irregular model, you need to cut it into several parts so as to
reduce the printing limitation and to better the print quality. Look at the model below:
