Z-SUITE is an application created specifically for Zortrax devices. The program prepares models for 3D printing by saving projects in the .zcode/.zcodex format. Apart from that, Z-SUITE allows you to change and adjust print settings, such as the size of the model, layer thickness, the type of infill or how many support structures will be generated. The following categories describe the program’s options step by step. The system requirements for Z-SUITE are listed below.

Welcome Screen


Preferences Menu



Adding an External LCD Printer

Go to the EXTERNAL LCD PRINTERS tab on the right side of the welcome screen and select Add external LCD Printer.

In the pop-up window, enter the following information:
Printer name,
Printing volume (X, Y, Z),
Horizontal resolution,
Vertical resolution,
File format.

Accept the parameters with the OK button. The added printer will appear on the list.

NOTE: Some Z-SUITE options may not be available when preparing a model for an external resin printer.


At any point of preparing a model you can add a new tab and either start work on a completely different project or try other print settings for the same model. As with any website browser, you can add a tab by clicking the “+” icon next to the already open tab.

It’s easy to switch between multiple tabs. They function independently so it’s possible for you to work with several 3D printers at the same time.

My Devices Panel

The My Devices panel allows you to work with one or more Zortrax device (M Series Plus and Inkspire printers, or Zortrax Apoller) that are connected to the local network (using either Wi-Fi or the Ethernet cable).

Once you open this tab, you can search for devices available in the local network and add them to the program’s panel. Select the icon with your devices’s IP address and click on it to add the device to the panel. You can also add a device manually by typing its IP address.

Each added device can easily be managed within Z-SUITE. You can start, stop, and pause the printing process (M Series Plus), see the device’s current state, change the name of your device, preview basic information about the device, or display the preview from the printer’s camera (M Series Plus).

Each time your added device finishes the printing or smoothing process, you get a notification in the panel. The notification is displayed in the top right corner of the device’s icon (blue question mark) and on the bar with tabs (red circle).

In the 3D Printer Files tab, you can preview all .zcodex files that are stored on the USB flash drive. The .zcodex files can be directly transferred from the computer to the printer over Wi-Fi or Ethernet cable.


Step by Step

The whole process of preparing a model is divided into four individual steps: MODEL, PRINT SETTINGS, SUPPORT and PREVIEW.

Selecting / Adding / Deleting a Model


Workspace View


Moving a Model

Click the Move Model icon to change a model’s position in the workspace in one of the three axes. Next, select a model and move it manually along the X or Y axis, or both axes simultaneously. You can also use the “+” or “-“ buttons to move a model by millimeters in the selected axis.

The Move Model option also allows you to change a model’s position in the Z axis and, for example, place several models on top of one another. To print several models in this arrangement, you need to remember to generate proper support structures.

You can move your models with the control grips marked red, blue and green. The grips can be enabled in the Preferences menu.


Auto-Arranging Models

Use the Auto-Arrange Models option to let the program automatically place a model or several models in the workspace.


Resizing a Model

Select the Resize Model icon to resize the X, Y and Z dimensions of a model. You can change the parameters manually or by using the “+” and “-” buttons. Click the padlock icon to scale a model only in a selected axis. To make it easier, you can use the control grips (marked red, blue and green) – click and hold one grip, and move your mouse to change a model’s dimensions.

You can acquire the desired dimensions of a model by typing the exact value in millimeters. Just click the “%” button to switch to “mm.” This option becomes useful whenever you want to change the height or width of a model and be sure of the precise measurements.


Rotating a Model

With the Rotate Model option you can rotate a model in the in the X, Y and Z axes. To rotate a model, adjust the value in an appropriate field using the “+/-“ buttons. Additionally, this option allows you to change a models’ position by 45°. You can also rotate a model using the control grips marked red, blue and green. By clicking the FLIP button, the program can reverse your object’s structure, as in a mirror.

The Place by face tool allows you to rotate a model so that the selected face of the model is placed on the platform’s surface.

You can revert to a model’s initial position by clicking the Reset Rotation button.


Rotation Optimization

FDM Technology

The Rotation Optimization tool allows you to choose one optimal position for a model according to your chosen parameter: Min. Support Area, Min. Support Volume, Max. Platform Contact, and Mixed. Each parameter helps you achieve different results and improve the efficiency of 3D printing in a different way. The parameters depend on the printing technology and Zortrax printer you’re going to use. You can either focus on better surface quality, reduce material usage, optimize the number of needed support structures, or speed up the printing process.

Once you select the Support angle and click Search, the program will show you 4 available types of rotation. Choose one position and move on to the next step.

UV LCD Technology

This tool is also available for UV LCD printers. In this case, the program shows 3 types of rotation: Min. Support Area, Max. Platform Contact, and Mixed. Choose one position for your model and move on to the next step.


Splitting a Model


Placing (multiple) Models


Copying and Deleting a Model


Preparing to Print

Once you determine a model’s size and position in the workspace, you can change and adjust the Print settings. The Print settings menu is divided into Normal and Advanced settings. In this menu, you can define all parameters influencing a model’s quality and durability, such as the layer thickness, the type and density of infill or the fan speed.


Normal Print Settings (FDM)


Model Analysis (FDM)

Z-SUITE 2 is able to check whether a model has walls which are too thin to be printed and mark them in the preview. In the Print settings step, click the last icon on the left bar. Select Verify and the program will carry out the analysis.

If after the analysis your model has sections marked red, it means that there are walls thinner than 0.4 mm and, due to the minimum wall thickness requirements of Zortrax printers, may not be printed at all.

Once you generate the .zcode/.zcodex, those non-printable structures won’t be included in the preview. If you encounter problems with too thin walls but you don’t want to give up on 3D printing that particular model, use 3D modeling software to correct the model’s structure prior to loading it into Z-SUITE 2. Using this option is optional – if you’re sure your model is well-designed, you can move on to the next step.


Advanced Print Settings (FDM)


External Materials Settings (FDM)


Normal Print Settings (UV LCD)


Advanced Print Settings (UV LCD)




Z-SUITE 2 allows you to create customized profiles which you can test and print with as many times as you wish. Once you choose the best settings for a given model, you can save your profile and store it in the program’s memory.
Use the Save option and name your profile. It will be included in the drop-down list.

There are also several ready-made profiles with default settings for different types of models. The profiles’ names indicate possible applications of models.


Slicing a Model


Replicating .zcode/.zcodex Files

Once you’ve generated a .zcode/.zcodex file, you can create several copies of the already prepared model and place them in the workspace. Select the Replicate .zcode/.zcodex tool icon, type in the number of copies you want to create, and click Replicate.

Z-SUITE will automatically arrange the models on the platform and won’t allow more copies than it is possible to place in the workspace.

Each copy will have the same print settings, including the position of seam and supports.


Calculating the Print Cost


The print cost calculator in Z-SUITE 2 allows you to estimate the cost for an individual print. To calculate the print cost, simply type the cost of a single spool. Press the Calculate button to see what the total cost of the print will be.


Support Adjustments (FDM)


Support Adjustments (UV LCD)


Smart Bridges


If your model has small holes (below 8mm) in its structure, it is advisable to enable the Smart Bridges option. Then, these holes will be supported with special, easily removable “bridges.” Once you disable this option, small holes will have the regular type of support which may be hard to remove.


Weak Spots


Weak spots are particular points in a model’s structure which can easily break once you apply force to the whole object. Such spots appear in 3D prints due to the direction of printing. In the FDM technology, layers are applied onto one another in the Z axis. It means that if the force is parallel to the printed layers, your model will crack and break. That’s why, you should evaluate the object’s intended purpose and position it properly before the printing process to eliminate weak spots. The graphic shows the spool holder used in Zortrax printers. It has to support the weight of a spool during printing and should be printed horizontally so that the bending forces will be carried perpendicularly to the layers.


Position and Print Quality


Choosing your model’s orientation can highly influence its final look as well. Remember that when a layer bonds with the already solidified previous layer, there will remain a slightly visible spot on the print’s surface. That’s why, by positioning your model differently, you can easily eliminate most imperfections from external surfaces which you want to be as smooth as possible.




Once you generate the .zcode/.zcodex, click on the button below the report section on the right to copy the content of the print settings report to the clipboard.

Z-SUITE 2 will save the print settings in a separate text file together with the .zcode/.zcodex.
