Do I get the whole set at once?

No. Each run makes one piece: start with the King, then pick Queen, Bishop, Knight, Rook and Pawn to complete the set in the same theme.

Will the pieces match?

Yes. The theme and style stay the same, and each piece keeps its classic height so the set reads clearly on the board.

What size should I print?

For a standard board, about 9 cm for the king and 5 cm for pawns. Print each piece with the same scale factor.

What is 3D AI Studio?

3D AI Studio is a web app that makes 3D models, images and sounds with AI. It runs in your browser, so there is nothing to install.

A template is a saved recipe. It runs a fixed set of AI tools with settings we've already tested, so all you add is a photo or a sentence.

Runs in your browserPhone or computer

Inside this template

Step 1
Image Studio
Draws a picture from a sentence or a sketch.
Step 2
Image to 3D
Turns a single picture into a textured 3D model.

Your download

The files you get

STLThe standard file for 3D printers.

Open it in a slicer such as Bambu Studio, PrusaSlicer or Cura, then press print.

3MFA newer print file that also keeps size and colours.

Best for Bambu Lab and Prusa printers.

OBJA universal 3D file with its colour texture.

Opens in Blender and almost every 3D app.

Best results

How to describe it

Short themes work best: "Pirates", "Robots", "Ancient Egypt".
Make two themes face off: "Pirates" for white, "Royal navy" for black.
Add weights or a coin in the base during printing for a premium feel.

Good to know: Each run makes one piece; a full set is six runs (king, queen, bishop, knight, rook, pawn).

Chat brief · Themed Chess Pieces

Use the 3D AI Studio MCP to run the "Themed Chess Pieces" template (https://www.3daistudio.com/templates/custom-chess-set) for me.

My idea: Pirates
Piece: King
Side: Theme colours

Follow these steps in order. The prompts and settings are the template's own, so use them word for word and only put my idea where it says {MY IDEA}.

1. Design the piece
Call generate_image_nano_2_1 with aspect_ratio "1:1", resolution "1K", output_format "png" and this prompt:
"""
Chess set theme: {MY IDEA}. Piece: the KING, the tallest piece of the set, crowned and regal. A single chess piece from a custom themed chess set, designed for 3D printing: the theme is expressed through the character, costume and details, while the piece stays instantly recognisable as its chess role by height and silhouette. It stands on a round, weighted, stepped chess-piece base. Compact and sturdy, no thin parts sticking out, everything attached. The entire piece visible with generous empty margin, centered, frontal three-quarter view. Crisp sculpted detail. Isolated on a seamless pure white (#FFFFFF) background, soft even studio lighting, no shadows on the background, no other pieces, no board, no text.
"""
If I want to start from a sketch or reference image instead, call upload_image so I can hand it over, then call edit_image_gpt with the upload in images, quality "low", output_format "png" and this prompt:
"""
Turn the drawing in the reference image into a chess piece, keeping its design and colours. Piece: the KING, the tallest piece of the set, crowned and regal. A single chess piece from a custom themed chess set, designed for 3D printing: the theme is expressed through the character, costume and details, while the piece stays instantly recognisable as its chess role by height and silhouette. It stands on a round, weighted, stepped chess-piece base. Compact and sturdy, no thin parts sticking out, everything attached. The entire piece visible with generous empty margin, centered, frontal three-quarter view. Crisp sculpted detail. Isolated on a seamless pure white (#FFFFFF) background, soft even studio lighting, no shadows on the background, no other pieces, no board, no text.
"""

2. Build the 3D model
Call generate_prism_3_1 with the task_id of the image from step 1 in images, texture_model "3.5", texture_quality "fast", geometry_quality "standard", pbr false.

3. Export
Export it for printing: call convert_model on the 3D model with output_format "3mf" (or "stl" if I ask for it), plus max_size and unit "cm" if I gave you a print size.

After each generation call, keep polling get_generation with its task_id until it completes, then show me the result with show_generation before you start the next step.

Or automate it with the API

The same tools are available through the 3D AI Studio API. Call them from your own code to make hundreds at once, build them into your app or run them in your pipeline.
