Aim:

To prepare a 3D model created in Blender for 3D printing using slicing software.

Requirements:

• Computer with Blender

• Slicer software (e.g., Ultimaker Cura, PrusaSlicer)

• Access to a 3D printer (optional for demonstration)

Step-by-Step Process

Step 1: Export Your Design

1. Finalize your Blender model (make sure it’s scaled correctly and free of errors).

2. Click File → Export → STL (.stl).

3. Save the file in a folder named “3D Print Projects.”

4. Check the file size — large files may mean too much detail for fast printing.

Tip: Keep your design watertight — no holes or overlapping surfaces.

Step 2: Import into Slicer

1. Open your chosen slicer (e.g., Cura).

2. Drag and drop your .STL file into the workspace.

3. The slicer will automatically show a preview of your object on the print bed.

Note: Ensure the model is flat on the print bed — if tilted, printing may fail.

Step 3: Adjust Print Settings

1. Layer Height: Set to 0.2 mm (standard quality).

   • Smaller values (0.1 mm) → smoother but slower print.

   • Larger values (0.3 mm) → faster but rougher surface.

2. Infill Density: Set to 20%.

   • Higher infill = stronger but uses more material.

   • Lower infill = lighter and faster.

3. Supports:

   • Enable “Generate Supports” if your model has overhangs or bridges.

4. Shells / Walls:

   • Set 2–3 walls for good strength.

5. Temperature & Speed:

   • Default settings usually work well for PLA filament (200°C nozzle, 60°C bed).

Pro Tip: Always preview before printing — check for hollow areas or missing supports.

Step 4: Slice and Preview

1. Click “Slice” in the software.

2. Watch the slicer simulate how the printer will move.

3. Use the layer slider to preview each layer — this helps identify errors.

4. Note the estimated time and material usage displayed by the slicer.

Step 5: Export G-code

1. Save your sliced file as .gcode.

2. Transfer it to your printer via SD card or USB.

3. (If available) Start the print and observe the first few layers — this ensures proper adhesion.

Observation Point: Notice how the object grows layer by layer — this is additive manufacturing in action!
