Chapter 1: 3D Printing Technology

3D printing is 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 Inventor 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

Inventor User Guide | www.flashforge.com 0086‐0579‐82273989

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 Inventor.

Using FlashPrint, you can prepare stl. files to be g. or gx. files for printing. Then the

files can be transferred to your Inventor via USB cable, USB stick or Wi-Fi.

1.1.3 Build the 3D Model

Once the output file has been transferred to your Inventor, it will start to turn the 3D

model into a physical object by laying down layers of filament.

Inventor User Guide | www.flashforge.com 0086‐0579‐82273989

Chapter 5: Build Plate Leveling

A correctly leveled build plate will almost always guarantee a quality 3D object.

When printed objects have issues, the first step to diagnose is to check and

double-check to make sure the build plate is leveled. A general rule of thumb is to

leave a gap that is 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 Inventor 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.

5-1

1. （5-1）From the main menu, select [Tools] and [Level]. The extruder and the build

plate will begin to move to the starting position.

5-2

Inventor User Guide | www.flashforge.com 0086‐0579‐82273989

2. （5-2）Take out the leveling card (QR-Code for leveling video can be scanned)

5-3

3. （5-3）Once the extruder and build plate stops moving, slide the piece of paper

continuously back and forth between the nozzle and the build plate. And

simultaneously adjust the knob just enough so that the paper causes a slight friction.

5-4

4. （5-4）Press [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.

5-5

Inventor User Guide | www.flashforge.com 0086‐0579‐82273989

5. （5-5）Press [NEXT]again and repeat the same leveling technique.

5-6

6. （5-6）Press [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.

5-7

7. （5-7）Press [FINISH]once you have finished this.

④Supports: When print with model contains part hanging in the air or top-heavy,

support is necessary. Click [supports] to create support part for the printing.

⑤Raft: This function will help the model to stick well on the platform.

⑥Wall: During dual color printing, this function will help to clear the leaking

filament of another extruder.

⑦Vase Mode: No capping for the model

⑧Resolution：

You have three resolution solution(with default setting)to choose from,

high resolution is corresponding with slow printing speed, opposite for the low

resolution.For PLA printing, an extra solution “Hyper” is available.

⑨More options: Click [More options] to set for layer, shell, infill, speed and

temperature. Different resolution solution is corresponding to different defaults, click

[Restore Defaults] to back to default setting.

●Layer

a. Layer: Layer thickness of the printing model. With a small number, the

surface of the model will be more smooth.

b. First Layer Height: This is the first layer of the model, which will affect the

sticking performance between the model and platform. Maximize is 0.4mm, usually

the default is ok.

c. Shell: Contains of the outside shell number, capping layer number (under vase

pattern, top solid layer setting is invalid.)

●Primeter Shells: Maximize is 10

a. Top Solid Layer: Maximize is 10, minimum is 1.

b. Bottom Solid Layer: Maximize is 10, minimum is 1.

●Infill

Inventor User Guide | www.flashforge.com 0086‐0579‐82273989

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.

6-14

●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, 80 is recommended.

b. Support Print Speed is needed to set when choosing Slic3r as the

slice engine which can control the moving speed of the extruder when printing

the supports.

c. Travel Speed is to control the moving speed of the extruder under

non-printing Status during work. for PLA printing, 100 is recommended.

8.1 Skills on Supports

(Reference Video：Skills on Supports)

Support structures enable the printing of models with steep overhangs and

cantilevered sections. The Inventor 3D printer utilizes Fused Filament Fabrication

(FFF) technology, which works on the additive manufacturing principle of heating

Inventor User Guide | www.flashforge.com 0086‐0579‐82273989

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

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, the 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)

Inventor User Guide | www.flashforge.com 0086‐0579‐82273989

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.

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

using for manually adding or deleting supports.

1）Manual Add

8-10

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

model.

Inventor User Guide | www.flashforge.com 0086‐0579‐82273989

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

needed. Press down the left mouse button and drag to generate the support.

2）Manual Delete

8-11

Like the picture above, a hole inside the model doesn’t need any supports.

Inventor User Guide | www.flashforge.com 0086‐0579‐82273989

Left click the [Delete] button and then left click the supports needed deleting. And the

support will be deleted.

8.2 Control over Printing Quality

①Enhance the build plate adhesiveness

●Leveling the build plate

●Keeping the build plate smooth and tidy

●Using the build tape or glue

②Adjusting 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)

8.3 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

to Platform)
