¶ Mask Mode
This feature allows you to add masks to specific areas of the model to precisely control the placement and quantity of fibre-reinforced materials. It also supports control over support structures: you can directly specify areas on the model where supports must be generated, or completely prohibit support generation.
Draw a mask
-
Click
to import a model in the right toolbar. -
Choose the model and click
to select a box or cylinder as the mask shape.
-
Press and hold the Ctrl key. Once the cursor becomes a plus sign (+), click and hold the left mouse button and drag to create the mask.
-
(Optional): When multiple masks are drawn, click
to the right of a mask to adjust its priority. -
(Optional): Click
to access the following operations:- name: Modify the name of the mask.
- Mask type:
-
Internal mask: The internal mask defines the internal structure of the part within the masked area. You can set the number of outer contour lines (shells) for this area. All regions outside the mask will be printed according to the global parameters of the profile. All internal mask bodies will share the same outer shell as the base part when printed.
-
Full mask: The full mask creates an independent region inside the model, where print parameters (including outer wall layers, number of contour shells, and top/bottom solid layers) can differ from the base model. In Enhanced Mode, you can enable or disable reinforced outer contours and set their count, and independently set the type and density of reinforced infill.
-
Support enhancer: Forces support generation in the specified area.
-
Support blocker: Prevents support generation in the specified area.
-
- Fill pattern: Selects the fill pattern for the mask, including grid, lines, triangles, etc. The actual patterns available are shown in the interface.
- Fill angle: Adjusts the angle of the fill pattern.
- Fill angle offset: Sets the incremental angle of the fill pattern per layer. For example, if the fill angle is 45° and this parameter is set to 30°, the first layer path will be 45°, the next layer path will increase by 30° to 75°, and so on.
-
(Optional): Right-click the mask (or select it in the left model area and right-click) to access the following operations.
- Rename: Modify the name of the mask.
- Delete: Delete the mask.
- Move: Enter coordinates to control the model’s position.
- Resize: Select the desired mode (Manual, Relative, or Absolute) and enter X/Y/Z values to scale the mask. When the Uniform option is enabled, adjusting any single dimension will automatically scale the other two proportionally.
- Rotate: Choose angle or manual, then enter X/Y/Z values to set the rotation.
- Convert to Part: Converts the target mask into a new model that can be printed as either a cylindrical or rectangular model.
-
(Optional): After converting a mask to a model, right‑click it for the following operations:
- Delete: Deletes the converted model.
- Add Mask: Adds a custom mask. Supported file formats include .stl and .obj.
- Use Model as Mask: Selects another model to serve as the mask for this model.
This feature requires at least 2 models.
- Clone: Duplicates the selected model.
- Move: Modify the X/Y/Z values to move the mask to the desired position.
- Resize: Select manual, relative, or absolute mode as needed, and modify the X/Y/Z values to scale the mask. Enable Uniform so that changing any one value automatically adjusts the others.
- Rotate: Select angle or manual mode, and adjust the X/Y/Z values to set the mask rotation.
- Export Model: Exports the model as an .stl file.
¶ Layup Mode
This feature allows you to customize print paths on a per‑layer basis to meet different requirements for infill direction, line pattern, and more.
Steps
- Click in the right toolbar and select Add layup.
- Enter the layer range values in the input box or drag
below the input box to adjust the range (the left side sets the minimum value and the right side sets the maximum value). In the figure below, the layer range is 0.00 — 2.23.
- Click Apply to confirm.
After selecting Reinforced Mode, you can also enable Generate reinforced perimeters and Generate reinforced fill, and adjust the parameters as needed.
- (Optional): Clickto the right of the layer range to access the following operations:
- External shell count: Sets the number of outer shell layers for the printed model.
- Plastic perimeters count: Sets the number of contour layers for the inner shell. This parameter directly affects the surface strength of the part.
- Fill pattern: Selects the fill pattern, including Grid, Lines, Triangles, etc. The actual patterns available are shown in the interface.
- Fill angle: Adjusts the angle of the fill pattern.
- Fill angle offset: Sets the incremental angle of the fill pattern per layer. For example, if the fill angle is 45° and this parameter is set to 30°, the first layer path will be 45°, the next layer path will increase by 30° to 75°, and so on.
- Fill density: Sets the density of the fill pattern.
¶ Printing Mode
The FibreSeeker 3 3D printer supports three printing modes: Speedy, Reinforced, and Fortified.
¶ Speedy Mode
The FFF nozzle works independently, delivering faster printing speeds and higher precision, making it suitable for standard 3D printing applications.
¶ 5.2 Reinforced Mode
The CFC + FFF dual‑nozzle system works in tandem to embed a fibre framework layer inside the printed part. The material ratio can be freely adjusted to achieve a precise balance between strength, weight, and cost.
¶ 5.3 Fortified Mode
The CFC nozzle operates independently, utilizing advanced technology to produce high‑strength components with a tensile strength of up to 900 MPa.
When print length or space is insufficient, plastic infill is used.
¶ Starting print
Within the slicing software, print parameters can be configured on the Template Settings area. The original parameters of built-in templates are non-editable. If you need customized template parameters, copy a built-in template first and adjust relevant print settings accordingly. For full instructions, refer to the FibreSeeker 3 User Manual.
- Rocket Slicer supports two methods for importing models:
- Click , or use the shortcut key Ctrl + O to import a slice file in the right toolbar. Supported formats include .stl, .step, .stp, and .3mf.
- Drag and drop the model file directly onto the print plate of the Rocket Slicer preparation page.
- Click
- Click ， ， in the right toolbar to adjust the model's position, size, and orientation.
When printing carbon fibre models, apply biomimetic principles to analyze the force‑bearing direction and select the optimal orientation accordingly.
- Select the target material profile (the figure below uses plastic as an example).
- Select the desired print mode in the Print Mode section on the left toolbar. For more details, refer to 5. Printing Mode. The figure below uses Reinforced Mode as an example.
- Click Preview at the top of the left toolbar to review the print parameters of the model, as shown in the figure below.
- You can choose between the following two printing methods:
- Direct Print: After connecting the printer, click Print Start in the lower‑left corner.
- USB Drive Transfer: When Rocket Slicer is not connected to the printer, save the model as a G‑code file on a USB drive, then insert the drive into the printer. On the printer touchscreen, tap
> USB, then select the target model for printing.
- Direct Print: After connecting the printer, click Print Start in the lower‑left corner.
