Step 5: Generate Image Previews

Click "Generate image (5)". The number shows how many credits this step uses. Your 2D preview will appear in about 20 seconds.

Review your preview:

You can generate as many previews as you need (in the limits of credits) until you get exactly what you want.

Step 6: Generate the 3D Model

Time to be concrete. Once you've selected your preferred image, click "Generate 3D model (45)". The number shows approximately how many credits this conversion costs.

This process converts the 2D image into a full 3D mesh optimized for printing. Generation typically takes 2-4 minutes.

Step 7: Download and Print

Once generation completes, download your model in print-ready formats. The mesh is automatically optimized with manifold geometry, making it ready to import directly into Lychee Slicer or your preferred slicing software.

Bonus Feature: Pose Option

Who is this for? Artists and creators working with humanoid characters or creatures who want to eliminate repetitive tasks. The Pose tab allows you to generate the base, saving valuable time to focus on the artistic step.

When to Use Pose Tab:

✓ Humanoid characters (warriors, mages, heroes)

✓ Models you plan to rig or animate

✓ Figures that need specific action stances

Example of Pose Options: Based on your own prompt and idea, available poses can include neutral or T-poses, standing poses, dynamic positions like combat stances or dramatic movements, as well as sitting, crouching, reaching, and other custom positions.

💡 Pro Tip: Even when using the Pose tab, reinforce the pose in your text description for best results. Example: "Fantasy knight in heavy armor, holding sword and shield, standing in defensive stance". This ensures the pose and the overall design work together perfectly.
