¶ Important Tips
Before internal engraving, confirm that the equipment is equipped with a UV 5W laser module and an internal engraving F-theta lens - F130, then follow the steps below.
¶ Operation Steps
¶ 1. Assembly & Positioning of Internal Engraving Stand
Detailed assembly guide for the internal engraving stand:https://wiki.creality.com/en/laser-engraver/falcon-t1/internal-engraving-stand-t1
¶ 1.1 Assemble the Stand
Screw the support pillars onto the base plate. Install the positioning rulers on the X and Y axes of the positioning panel respectively and tighten the screws. Then insert the positioning panel onto the support pillars.
¶ 1.2 Adjust the Positioning Rulers
Adjust the positioning rulers according to the actual size of the material to ensure the material is centered.Example: For a 50×50×50mm crystal, set the positioning rulers to 25mm.
¶ 1.3 Fix the Stand
Secure the fully assembled internal engraving stand at the center of the engraver’s working area.Do NOT lift only the working panel when moving the stand, to avoid component damage or positioning deviation.
¶ 2. Material & Model Preparation for Internal Engraving
¶ 2.1 Connect the Device
Open the FDS software, connect the device, and confirm it is Creality Falcon T1.Go to 【Workspace】 and select 【5W UV】 as the light source.
¶ 2.2 Select Processing Mode
Click 【Processing Mode】
Select 【UV Internal Engraving】 mode.
¶ 2.3 Set Consumable Dimensions:
Click the 【Material】 tab.
Select the form of processing consumables, enter the dimensional parameters according to the actual crystal specifications, click [Material], select the shape of the consumables, and enter the dimensional parameters according to the actual crystal specifications.
The software includes built‑in professional internal engraving parameters. Hover the mouse to view parameter descriptions.Modification is not recommended except for testing purposes.
Tip: When processing internal carving of crystal balls, it is necessary to cooperate with special processes to correct the spherical optical path. The curved surface of the crystal ball will cause irregular refraction and focal point shift of the laser, making it impossible to directly focus stably inside. This can be achieved bysolutionto make the top surface of the curved surface equivalent to a flat surface, allowing the laser to precisely focus inside the ball to complete the internal carving. That is, select internal carving oil/glycerin with a refractive index close to that of glass, high light transmittance, and safety and non-toxicity, place the crystal ball in a container of the same volume, pour in the solution to completely submerge it, and use the solution surface as a flat reference to compensate for spherical refraction, thereby achieving precise internal carving.
¶ 2.4 2.4 Import Model (Supports importing 3D models, 2D images, and text internal carving):
Supported file formats: 3D models: glb/obj/fbx/stl/ply, 2D: png/jpg/jpeg/svg/dxf, etc.
① Import 3D models / 2D images, click the import icon, select the model, and then control the position, size, and rotation angle by dragging or adjusting parameters
Select the model and press the delete key to clear the imported model
② Import text, click the text icon
Select the text, click Edit Text, and you can edit the text
Tip: Finer texture on the top surface. For best results, place the main view facing upward during processing.
¶ 3.1 Auto Focus
Perform auto‑focus directly on the assembled internal engraving stand.Do NOT place the crystal material at this stage. Correct focusing ensures an accurate border preview.
¶ 3.2 Border Traversal
Click 【Border Traversal】 to preview the actual engraving area on the internal engraving panel.Confirm the processing area before proceeding.
After previewing, place the crystal material tightly against the positioning rulers to keep it centered. Ensure the material is stable and not offset.
¶ 4. Start Internal Engraving
¶ 4.1 Start Processing
Click 【Start Processing】 to preview the full engraving path.After confirming no abnormalities, close the engraver protective cover, then click the start button to begin UV internal engraving.Do NOT open the protective cover during processing.
