Set Up Your Print
Open Uniz Desktop and click Control Button to show the 3D model viewer.
The main interface has five components:
1. 3D Viewer
4. Printer Control
Uniz provides printer control function based on USB and network connection. This function also supports multiple printers’ control. Printer connected via USB will be marked with the icon in the right printing tool bar.
Click the Search button in the tool bar to search all the printers (only selected printer type) in the same network of the computer which will be marked with the icon.
Printer connected via both USB and network will be marked with the icon and USB communication will be prior.
1 Only printers that are identical to the pre-selected printer type upon software start-up will be shown in the right toolbar.
2 More reliable connection will be preferable to use when there are many ways applicable in the printer.
The status bar appears along the lower edge of the window and shows software progress, such as the loading, generating support, and slicing progresses.
Load 3D Model
To load one or more 3D models, you may either drag-and-drop into the 3D viewer, click Load File Button from the Main Tools, or double click on the file directly (if Uniz Desktop is set as default software to open such file format). File format supported: STL, OBJ, AMF, 3MF and UNIZ.
UNIZ file does not support multiple load in parallel.
Clicking left mouse button on an object to activate it for further operations. Drag the pointer across objects to select multiple objects. The activated objects will turn blue once selected.
Viewing your model from preferred angle will benefit model positioning. To rotate the view, right click and drag around the activated object. To pan, hold the shift key and click-drag with right mouse or holding scroll wheel and move mouse around. To zoom in or out, use the scroll wheel.
Pressing the Position Button will open following sub menu.
- The activated object can also be moved by inputting X/Y/Z values in the field, press Enter to apply changes.
- Bring active part in contact with platform.
- Center active part on platform.
- Duplicate active part.
- Make sure the models are distributed evenly on build platform.
- Un-balanced forces on the build platform may result in inferior precision or cracking.
Press the Rotation Button on the main tools will open following sub menu.
Once the Rotation tab is open, hold the left mouse button on the object and move the mouse to freely rotate the object.
- The activated object can also be rotated by inputting X/Y/Z values in the field. Press Enter to apply changes. Uniz's orientation tools are relative, not absolute ,so the X, Y, and Z rotation angles reset to 0 degrees after applying a rotation.
- Press "To Align Bottom Plane " button to align the selected plane to the bottom of build platform.
- Click the Reset Button to restore the activated object to the original status.
Large Flat surfaces or Long Straight line with supports may be printed at oblique angle of at least 10º to the build platform for higher success rate. The forces during peeling may distort the extremely thin layer of a flat surface or a line mounted on the support structures if printed horizontally. If a planar surface or thin line is oriented at an oblique angle, there is only little overhang for each new layer. Furthermore, thin-walled parts occupy significant less area in a slice when printed at an oblique angle.
Press the Size Button on the main tools will open following sub menu.
- The activated object can also be scaled by inputting X/Y/Z values in the field. Press Enter to apply changes. The object will scale uniform in Uniform Scaling mode. And in Non-uniform Scaling mode it will scale for each axis without affecting the other axes.
- If you prefer to scale to a fixed ratio put value in the Scale.
- Click the Reset Button to restore the activated object to the original size.
- Units: toggle between millimeters and inches.
Changing an object’s size will break previously generated supports and you will need to redo these. Note that change size by modifying scale value does not support multi-select.
To meet requirements of models in different sizes and structural patterns, the software provides multiple support parameter options. Adjusting support parameters may lead to better printing results or printing failure which depends on the user’s printing knowledge.
There are two ways for generating supports: Automatic Generation and Manual Edit Click the Supports button on left to open the settings dialogue box:
Support consists of four main parts: base, body, connections and head. The wide flat base ensures it sticks to the platform. The connections are used to reinforce multiple long supports. The support head is perpendicular to the model surface, preventing the support from sticking to the model and facilitating the removal of the support.
Spacing sets the horizontal distance between supports automatically to control the support s density.
Diameter setting controls the thickness of support.
The shape of the contact position between the support head and the model is a ball. The thickness of the connection between the support head and the ball differs with the setting of Head Type.
The model size, the hollow part volume and the support thickness determine that head length should be set differently to avoid the support and model sticking.
Touch point Size
The touch point size between the support and the model needs to be weighed when setting up
- Small touch points are easier to remove, but printing may fail due to the overweight of the model.
- Big touch points increase the reliability of the supports but may overlap the details of the model surface and cause problems with removal, or may result in the loss of the model surface quality.
The software offers four base types: Point, Line, Triangulation and Plane.
Base thickness is set here.
Tick the Internal Support box and support will be created in the overhung part of the model to ensure it can be successfully printed when using automatic support generation. The lack of internal support can cause printing failure of the dangling part. The left picture below is with internal supports and the right one is without. This option is ticked by default.
Non Internal Supports
Supports will be generated where the angle of the model part surface and the horizontal direction is smaller than the Support Angle, otherwise they will not be generated. Bigger Support Angle will create supports for wider scope of model part. Set this value to prevent generating supports at steep places and to eliminate unnecessary supports. Users can manually set the angle ranging from 45°to 75°, and the default angle is 60°.
To ensure discontinuous exposure in part area under UDP mode, supports need to be tilted. Users can manually set the tilt angle ranging from 0°to 20°, and the default angle is 0°. The left picture below is with vertical supports and the right one is with tilted supports.
Select the model needs to add supports and adjust the parameters
Lift and Down
Clicking the Lift button will raise the selected model up 5mm from the platform.
Clicking the Down button will put the selected model down onto the platform.
Clicking the Generate button will start the automatic supports generation for the selected model by the software. The existing supports will be eliminated before the new supports generation.
All supports could be edited after switching to the Manual Edit mode no matter if they are selected or not. Only four parameters including Diameter, Head Type, Head Length and Touch point Size are adjustable in Manual Edit, and the other parameters will be the set values.
The Lift, Down, Generate buttons are only enable when a model is being selected and activated.
Enter/Exit Manual Edit
Clicking the Edit button will enter the Manual Edit mode where the model is gray and the supports are green. The supports bases will displayed as points even the Base Type is not Point for easily modifying their positions.
Clicking the Edit button will enter the Manual Edit mode where the model is gray and the supports are green. The supports bases will displayed as points even the Base Type is not Point for easily modifying their positions.
Clicking the Edit button again will exit the Manual Edit and enter the Automatic Generation.
The software offers two ways for selecting supports: clicking one support or dragging a box to cover many supports. The selected supports will be highlighted.
Trace mouse cursor over the model and there will be a line perpendicular to the model: when the line is green, clicking the surface will add a support; when the line is red, it means there is no need to add a support.
Modify Support Position
This function is applicable only when a single support is selected.
Left click on the support head and drag it to the target position to release, and the position of the support head will be modified.
Left click on the support base and drag it to the target position to release, and the position of the support base will be modified.
Dragging the base of the internal support onto the platform will change the internal support to non-internal support.
Dragging the base of the non-internal support onto the model will change the non-internal support to internal support.
Hold down the Shift key and drag the heads of simple supports in contact with the platform the supports will move as a whole.
If the model turns red during dragging, it means supports are invalid at this position.
Modify Support Attribute
Select one or more supports and then modify the four parameters including Diameter, Head Type, Head Length and Touch point Size. The corresponding attributes of the model will be updated simultaneously.
Click the Delete button to eliminate the selected supports.
In SLASH machines printing is layer by layer. If a point or a line or a plane is isolated and overhung in one layer, it will fall into the resin tank after cured. Users need to find all islands and overhung areas and add supports there.
When printing the large and solid model, please use thick supports and high support density by even distribution to provide enough support. Another possible way to reduce the quality of the model is to hollow it when slicing.
Press the Slice Button on the main tools will open two sub menus, the left menu is to start Slice and Show Slices, and the right drag bar and menu is for customization of slice profile.
This is customize the slice parameters of each segment of a model.
After version 1.2.0 and the upper Desktop sets a separate slider at the third layer by default and users cannot move this slider in the bar. The Exposure Time of the first three layers will be set directly in the slice parameter interface rather than in the advanced settings.
Since 1.3.0 version, "Slice Parameter Settings" has been adding "Preference" and "LED Power", accordingly "LED Power" window will be removed from "Advanced Setting" . Uniz Desktop will no longer memorize the last used "Exposure Time", therefore "Restore Default of Exposure Time" function be abolished. Users You can memorize favorite printing parameters by "Preference".
- "Preference": Each resin can define multiple preference to memorize frequently-used printing parameter, including: Layer Thickness, Exposure Time, Cool Down Time, Pixel ContractionShrink, LED Power, Motor Speed, Rise Height, Infill, UDP Mode. Click on button , pop out "Preference Editor" dialog.
- "LED Power": Setting the power of the LED module, the range is 0-300, 150-250 is suggested.
- "Resin Type" provides different default values for different resin type.
- "Thickness" is the layer thickness, which is related to Z resolution.
- "Exposure Time" is the exposure time of a layer in this segment, it may vary due to different layer thickness setting or different resin types.
When users modify the exposure time and execute slicing function, the system will record the new exposure time and the corresponding layer thickness and modify the suggested exposure time which will be applied during the next printing. Click the "Restore Default" button to use the preset value by the system.
- "Cool Down Time" is the time to cool down the exposed layer to protect the polymer film from overheating. For sustained low peel force and prolonged film life, it is recommended to keep the film temperature below 50deg C. Overheating will cause the film to warp, delaminate, or even break.
In "Preference Editor", to create a new preference by clicking "Add". Preference values are determined values that represents current slice parameters setting. There are not editable;
Preference name is editable. Note: Self-defined name that is repeated or including special character like &:,;"?#%~/ is invalid.
In "Preference Editor", choose "preference", click "remove" button to delete. Only self-defined "preference" is deletable.
Avoid exposing the same spot or area over and over, try to orient the model’s walls or pillars in oblique angle so the exposure area changes every next layer.
Pressing the "Advanced" Button will open following sub menu
- "Pixel Shrink": Shrink or expand the slice polygons.
For more details, see: Slice Shrink Setting
- Motor Speed defines the speed of electric motor that controls the peel motion of the platform.
- Rise Height defines the travel height of the peel motion.
- Infill:You can drag the slider horizontally to modify the infill ratio ranging from 0% to 100%. The model will be：
- hollowed but not filled when the ratio is 0%；
- hollowed and filled by the ratio when the ratio is among 10% to 90%;
- filled but not hollowed when the ratio is 100%;
Please view Advanced Settings for the hollowing wall thickness and infill type.
- Users need to check this box when printing UDP model. UDP mode can only be
used when the following requirements are met:
- 1. A printer with UDP mode support is connected and selected in the interface, such as SLASH PLUS UDP；
- 2. UDP resin is loaded and the corresponding resin type is selected in the interface, such as zUDP ORANGE;
- 3. A slice thickness supporting UDP mode is selected, such as 0.100mm.;
- Pause sets a pre-set pause at the layer of choice during printing, the pause can be resumed after pressing the Resume Button in the printing control tab.
Customize Your Own Z Resolution
Dividing the model into multiple segments and define different slice parameters, Z resolution customization can be used to balance print speed and surface quality.
Click the block on the slider bar to start customizing print parameters. The white line shows the division layer of the two adjacent segments. The upper menu sets the segment above the division, and the lower menu sets the segment below. You may drag the slider block to change the division location or double click on blank space on the slider bar to add another division layer. Press Delete key when dragging the slider block to erase the division layer. The last division layer cannot be deleted.
Double click the selected slider and you get a text box. Type layer in the text box and then press ENTER key to finish and close the editing.
Note: The value must be between the upper and lower segments.
Click the "+" Key to move the slider upward for one layer till to the top of the slider or the next layer of the up slider.
Click the "-" Key to move the slider downward for one layer till to the previous layer of the down slider.
Notice: The slider at the bottom (the third layer) does not support operation by the +/- button.
