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

9

·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.

InventorⅡ User Guide | www.flashforge.com 0086-0579-82273989

Chapter 7 : Advanced Printing

When you get familiar with your InventorⅡ, you will definitely want to accomplish

some advanced prints. This chapter will take you to get to know the advanced printing

skills.

Expert Mode grants the users more freedom of parameter edition. There are two

modes are available for users, one is “Basic Mode” and the other is “Expert Mode”.

7-1

Select Profile: Allows users to select the required scheme. There are three options for

users (low/standard/high/high) and the default is PLA standard. Different schemes

correspond to different parameter settings. High-quality scheme produces

high-resolution object but at a low speed. On the contrary, low-quality scheme

produces low-resolution object but at a high speed. When printing with PLA, users

will find a “hyper” option available.

General:

a. Layer Height

Thickness of each layer. The less thickness of layers, the more time will be used and

InventorⅡ User Guide | www.flashforge.com 0086-0579-82273989

60

the better model will be printed.

b. First Layer Height

When printed with thinner layers, comparative thicker bottom layer could improve

adhesion and tolerance for non-perfect build plates.

2）Speed

a. Base Print Speed: The fiducial value of extuder’s movement speed during

printing(For subsequent speeds counting ). With a lower speed, the printer can build an

objects with higher resolution and more smoothness.

b. Speed at which extruder moves when not extruding filament.

c. Minimum Speed: The minimum extruder’s movement speed during printing

d. First Layer Maximum Speed: The max printing speed for printing the first

layer(Note: It’s invalid to the model which has a raft )

e. First Layer Maximum Travel Speed: The max travel speed for printing the first

layer(Note: It’s invalid to the model which has a raft )

3）Temperature

It displays the temperature of “Extruder”.

4）Retraction

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.

Principle of 45 Degrees①

Generally speaking, if the 3D model has an overhang of more than 45 degrees, you

InventorⅡ User Guide | www.flashforge.com 0086-0579-82273989

68

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.

Principle of P②roportionality

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.

Manual Modification

7-9

For the experienced 3D printer users, the [Add] and [Delete] buttons are suggested

using for manually adding or deleting supports.

1）Manual Add

7-10

You can add the support structure manually to according to the actual shape of the

model.

Left click [Add] on the left, and then click on the position when support structure is

InventorⅡ User Guide | www.flashforge.com 0086-0579-82273989

73

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

Enhance the build plate adhesiveness①

● Leveling the build plate

● Keeping the build plate smooth and tidy

● Using the build tape or glue

Adjusting the printing speed②

● 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

InventorⅡ User Guide | www.flashforge.com 0086-0579-82273989

74

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- Surface ⑦

to Platform)
