INTRODUCTION
1.1 What is 3D Printing?
3D Printing is a process whereby a real object is created from a 3D Design. Fused Filament
Fabrication (FFF) is one of the most common technologies used by 3D Printers to achieve this.FFF
works on an 'additive' principle by laying down material, such as PLA or ABS filament,in layers to
create a 3D object.

3D Design
Having a 3D design is the first step to creating a 3D Object.
There are a number of free 3D Designs that can be downloaded
and printed for personal use. Websits such as Thingiverse.com,
Pinshape.com and YouMagine.com are a good place to start,
but there are many more available!
Alternatively,you can create your own 3D Design using 3D Modelling Software. Programs such as
Sketchup or Blender allow this, however this can take some practice before successfully modelling
your 3D Design. After you've finished your 3D Design,you can export it as an. STL file,to be imported
into a 'Slicer' program such as Cura.
Slice to GCODE
A 'Slice' converts a 3D Design (usually an .STL or .AMF format)into
individual layers. It then generates the machine code (such as GCODE)
that the 3D Printer will use for printing.
We recommend the program Cura as it uses a simple interface and includes a large amount of

support material.
Setup WANHAO 3D Printer
It's important to check your printer before every print.We've included
some steps on page 21 in section 4.2 Good 3D Printing Practices
for you to quickly refer to each time.
3D Printing Process
Now that you've loaded a GCODE file onto the printer,it will
commence heating up the Extruder, then start printing. While
printing, the nozzle will move along the X and Y acis as each layer is
printed. This can take some time,depending on the size of the 3D
model, print speed of the 3D printer and resolution of each layer.
Here is an example of how size,infill,and resolution can affect printing time:

results are certainly worth it, with 3D models ranging from simple to complex.

4.3 Removing 3D objects from the bed
Once the I3 Mini has completed printing your 3D printed object follow these steps to
remove it from the print bed.
1.
Once the print is completed,wait for the extruder to cool and then turn off your 3D printer
2.
Using the supplied, carefull'wedge'under one of the edges of the 3D object.Take
care to keep the scraper flat with the bed to preven damaging the print mat
3.
As one edge begins to lift,gently maneuver the scraper forward to continue to'wedge
between the 3D object and print bed
4.
Once the 3D object has fully separated from the print bed,it is safe to remove
NOTE:
*
Always take care when using the scraper.Never use excessive force scrape towards your hand.
Scrape away from the body and keep hands clear to prevent injury
*
Always keep the scrape as level as possible.Scrape can damage the print mat if not used
corretly
*
Removing a 3D object,particularly one with a large surface size, can be a long process.Never
rush when removing a 3D printed object
TIP: If you are persistently having trouble removing 3D printed objects, try the following:
*
Use a layer of bule masking tape(designed to not leave behind residue) on the print bed.Be
sure to remove and replace after each print
*
Check if the printing mat is damaged and replace if needed
*
Replacement mats can be purchased at https://www.wanhao3dprinter.com
4.4 Removing Filament

4.8 Storage
PLA filaments are sensitive to moisture. If stored in a humid environment,the quality of the
filament can deteriorate,with a tendency to bubble and spurt from the nozzle tip.This will
affect print quality,so when stroing PLA or other material for an extended period of time,
follow these tips.
* Store in a sealed,air tight bag/container.We recommend a vacuum seal bag
* Store with a silica gel (moisture absorber)pack. One is included with each filament spool

4.9.1 Saving files to MicroSD Card
*
*
*
Format new MicroSD Cards up to 32GB to FAT32
Save files only in the root directory on the MicorSD Card.The I3 Mini will not read files in
folders.
Ensure your models are saved as GCODE files.STL and other 3D file formats should be
converted or 'sliced' into GCODE before loading them on the MicroSD Card. See the section
Creating a GCODE file using Cura for information on creating GCDOE files
4.9.2 Creating a GCODE file using Cura
A GCODE file provides the essential temperature settings and movement information for your
WANHAO I3 Mini. A number of 'Slicer' software programs exist which convert a 3D model file
