Q. What software can I use to make 3D models?

A.   Soildworks, Rhinoceros, Autodesk123D Design, 3D Studio Max etc. that can export a CAD model as a .stl file.

Q. Where can I find a 3D model in .stl file to print on my machine?

A.   You can download 3D models online from Thinkiverse or others websites....

Q. Once I have the .stl file, how to prepare it for printing? 

A.   Use KISSlicer to convert .stl file to g.code file. You can learn more in KISSlicer Tutorial below.

Q. A .gcode file can be print by ALL 3DP printers?

A.  No. There are different settings of KISSlicer for different printers. Please slice your files with our pre-configured KISSlicer.

Q. Can I check the size of 3D models on control panel?

A.   No, you can't. However, you can check the length of grid in KISSlicer.

Q. Can I set the number of print objects directly from the control panel?

A.   You can set the No. of count in KISSlicer before slicing.

Q. Can I set the percentage of infill/ support/ foot etc. on the control panel?

A.   You can master these in Support settings before slicing. You can check out KISSlicer Parameters below:

About KISSlicer

KISSlicer is our suggested 3D models slicing program. Slicing is a process that can convert a 3D model in a .stl file into a .gcode file, which is a format that can be read by 3D printers.

On our Support page you can find:

  • The latest KISSlicer version with pre-configured settings for each 3DP printer.

  • Test print files.


KISSlicer Setting Tutorial

In this tutorial is trying to introduce some common use button in this program with our pre-configured settings and test print files. All you need are:

    • KISSlicer with pre-configured settings

    • The test print files

    • SD Card (FAT32 format)

    • Windows or Mac computer that can run KISSlicer and can read/write on a SD card


1. Launch KISSlicer.exe > Click [Open] on the top right hand corner > Browse a .stl file

    Or Drag and drop this file from the file browser to the KISSlicer window.

2. Click the [Slice] button on the top right hand corner.

3. KISSlicer will begin to slice the object layer by layer.

4. You can insert SD card into computer.

5. Once the slicing process is done, [Slice] button will change to [Save] button. So you can save as .gcode file.

6. Insert your SD card into the printer and select the test print file [1 x l cube.stl]

    For Delta Series

    > - - - - - - -

    For EZ Dimension

    > Print File button on remote control             > [1 x 1 cube.stl]

    For Printer Robot - II

    > SD card                                              > Print File                                              > [1 x 1 cube.stl]


7. Select the file and start the printing process.

    For Delta Series

    - - - - - - - -

    For EZ Dimension

    The Smart Cartridge will start to heat up to 160 degree Celsius. After this, auto calibration will start and Smart Cartridge will           further heat up to 195 degree Celsius.

    For Printer Robot - II

    The Smart Cartridge will start to heat up to around 205 degree Celsius.  After this, auto calibration will occur and                         printing starts.


8. Check the height of the Smart Cartridge when it is printing the first layer. The first layer is important to a high-quality print model.

9. If the first layer is in poor quality, we suggest you restart the print job.

    For Delta Series

     > SD Card                                             > Stop Printing


KISSlicer Setting Parameters

We are going to introduce some commonly used parameters to you and explain in detail.

1. Style

Skin Thickness

This setting is to make sure there is a set of material on all direction of the outer surface of the object. This will affect the thickness of the base too.

Extrusion Width [mm]

The width of the extruded filament. It sets to 0.4mm according to the diameter of Smart Cartridge nozzle. The extrusion width will affect the spacing between loops.


Number of Loops

The number of loop of filament forms the perimeter of the object. The larger the value is more stable but it takes longer time to print. It is usually set to 3 and gives a minimum perimeter thickness 12mm.

Infill Extrusion Width [mm]

This will affect the filament thickness of the infill. Our pre-configured setting is 0.4mm. It is set to match the extrusion width or increase the strength of the object.

Layer Thickness [mm]

The thickness of one layer print along Z axis. It is usually set to 0.2 mm. You can also set it as low as 0.05 if necessary. Layer thickness is directly affecting the printing time of an object. The thick the layer takes shorter time to print and vice versa. However, thinner the layer will result in more precise and smooth print surface.

Inset Surface [mm]

The positive value will result in shrinking of all surfaces inward. Negative value will result in swollen of the surface.

Infill [%]

It is use to set the density of infill within the boundary of the loops. 100% infill setting is not necessary. Lowering the infill % can reduce the printing time, save materials and lighten the object. We suggested you set this according to the object size. Our pre-configured setting is 10%.

Infill Style

There are three type of style can choose: rounder, octagonal and straight. Octagonal style is commonly used.


Stringing is thin spider web like filament between two non-continuous paths. [De-String] helps to minimize stringing by retracting the filament back into the cartridge before it moves to the next path.


We suggest click this to minimize stringing. Smart Cartridge will backtrack on its last path before it jumps into the next non-continuous path.


2. Support

Support Density

It is use to adjust the density of the support structures. The support is off on the left-most side, the support is the denser on the right-most side. The denser the support, the more ridge the object but takes longer time to print. Sometimes loose density is already enough for support.

Inflate Support

It is use to adjust footprint and column of support.

Support Degree

The number indicates the maximum degree of overhang without support. Our pre-configured degree is 54 degree.


It is the space between the support and object. The smaller the gap, the more effective it is. Default setting is 0.8.

Support Z-Roof [mm]

It is a cutoff height support. Default value is -1 that will disable this function

Raft Type

[Grid] Create thin crosshatched base below the object.

[Pillar] Elevated thin crosshatched base.

[Skirt] Support around the perimeter of the object.

Inflate Raft

It is useful to increase the surface area of object that having little surface area.

Prime Pillar

A cylinder pillar will be created next to main object. It provides time for main object to cool down.

3. Material





















Fliamemt diameter used for all 3DP printer are 1.75mm.


  • Main layer is 210 degree Celsius

  • First layer is 210 degree Celsius

  • Keep-warm is 120 degree Celsius

  *We recommended keeping the value 195 to 210 degree Celsius for New PLA.



These are the further settings for [De-String] in the [Style] tab. As the properties of different materials vary, these settings are required to customize for each type of materials to minimize stringing.

[Prime] Set to 7.55mm to feed the filament before start printing. It should match [Suck] value. It should not be set over 10mm as it               may clog the nozzle?

[Suck] Set to 7.5mm to retract filament into cartridge nozzle before it starts to print a new path.

[Wipe] Commonly set to 7 or less. The value should be smaller for small object. This printer will push this length of filament when                the printer is ready.

[Speed/mm/s] It is the speed of filament prime and suck. Recommended set to 80mm/s or above to prevent filament clog in the                           nozzle. You can have further settings for speed here: 






[Min Jump/mm] Usually set to 0 or 1mm.

[Trigger/mm] The printer will apply de-string or wipe once you set the distance. Default setting is 20mm. You can set a lower                            value for small object.


Fan/ Cool

[Loops] The value 100 will run the fans as full speed while 0 will disable the fan.

[Inside] Set the fan speed when you print infill.

[Cool] Set the fan speed when the printer is slowing down.

[Fan Z] It affects the cooling of the first layer of the object to ensure it is tightly attached.

[Min Layer] It is the minimum time to print each layer. If the time to print a layer is lower than the setting, the printer will slow down                     to print and provide more time for cooling.


Flow Adjust

It is the fine adjustment of the volume in extrusion. Default setting for New PLA is 1.


It is the uplifting distance of the cartridge after one layer print. Lower value can prevent stringing, while higher values can prevent the scraping between nozzle and the object.
