AI 3D Model Generator

Turn a photo or a text prompt into a 3D model with Hunyuan3D or TRELLIS.2, check it in the 3D preview, then download STL, OBJ or GLB for your printer. AI 3D models start at 25 credits.

Quality25 credits

AI builds a full 3D shape from your photo. Untextured, made for printing.

Credits come back automatically if a generation fails on our side.

What it makes

What this AI 3D model generator makes

AI 3D modeling without CAD: three AI models build a full object, sides and back included, from a photo or a few words.

Hunyuan3D v3.1 Rapid

Runs Pro in the Image to STL tab and Fast in Text to 3D. It returns an untextured mesh, which is all a single color print needs.

Hunyuan3D v3.1 Pro

Runs Ultra and Text to 3D Pro. It returns a model with color textures, can take back and side photos on Ultra, and can add PBR materials.

TRELLIS.2 from Microsoft

An open image to 3D model in the Trellis-2 tab. You set the resolution and texture size, and it always returns a textured model. Read the TRELLIS.2 guide.

A photo or a text prompt

A photo fixes the shape and proportions of something that exists. A prompt can describe anything, but you control less of the result.

How it works

How the 3D model generator works

  1. 1

    Give it a photo or a prompt

    Upload one photo, add back and side views on Ultra, or switch to Text to 3D and describe one object.

  2. 2

    Choose a model and generate

    The Generate button shows the credits. They are taken when the job starts, and most models finish in 1 to 3 minutes.

  3. 3

    Scale it and download

    Spin the result in the 3D preview, type the print height in millimeters and save STL, OBJ or GLB with no extra charge.

Models and credits

Which AI 3D model to pick

Credits are charged once per generation. Every download of the result is included.

Image to STL, Pro

Hunyuan3D v3.1 Rapid from one photo. An untextured mesh for single color prints.

25 credits

Image to STL, Ultra

Hunyuan3D v3.1 Pro with color textures. Back and side photos and PBR materials cost 15 credits each.

35 credits, add-ons +15

Text to 3D, Fast

Hunyuan3D v3.1 Rapid from a prompt of up to 200 characters. Untextured, ready to slice.

25 credits

Text to 3D, Pro

Hunyuan3D v3.1 Pro from a prompt of up to 1024 characters. Textured, with optional PBR materials.

40 credits, PBR +15

Trellis-2

TRELLIS.2 from one photo at 512, 1024 or 1536 resolution, with textures up to 4096 px.

25, 30 or 35 credits

Basic relief (not AI)

A raised relief of a picture, built in your browser with a free 3D preview. For logos and signs, not full objects.

2 credits per STL
Prompt tips

Text to 3D model prompts that print well

Text to 3D builds what you describe, so describe something a printer can make.

One object per prompt

Ask for a single thing, such as a sitting fox, not a fox and a rabbit in a forest. Scenes and backgrounds are hard to print.

Chunky, simple shapes

Ask for a chunky, stylized or rounded look. Thick forms print more reliably than realistic fur, hair strands or lace.

No thin parts

Swords, antennae, whiskers and open fingers snap or fail. Ask for arms close to the body or a tail wrapped around the feet.

Describe the pose and the base

Say how it stands and what it stands on. Sitting upright on a round base gives a flat bottom that holds the bed.

An example prompt

A chunky owl figurine sitting upright on a round base, wings folded against the body, stylized, no thin parts.

Fast or Pro

For a single color print, Fast is enough. Pro adds color textures for painting reference, renders and viewers, and allows longer prompts.

Print checks

From AI 3D model to a printable STL

Every result downloads as an STL sized in millimeters, so this works as an AI STL generator and an AI 3D print generator in one step. A few checks turn it into a clean print.

Set the height first

AI models have no real scale. Type the print height, 10 to 300 mm, before you save; STL and OBJ follow it and the GLB keeps its original size.

Flatten the base

A rounded bottom touches the bed at one point. Cut 1 to 2 mm off in your slicer, or ask for a round base in the prompt.

Check wall thickness

Keep walls and small parts at least 0.8 mm thick, two lines of a 0.4 mm nozzle. If details are thinner, print the model larger.

Repair in the slicer

AI meshes can have small holes or stray floating pieces. If your slicer flags mesh errors, run its repair and delete loose bits.

Orient and support

Turn the model so supports land on its back, not its face. Tree or organic supports suit the curved shapes of figurines.

FAQ

AI 3D model generator questions

Credits, refunds, file formats, timing, commercial use, back and side photos, PBR, and text versus photo.

How much does the AI 3D model generator cost?
Each generation costs credits: Image to STL Pro 25 and Ultra 35, Text to 3D Fast 25 and Pro 40, Trellis-2 25, 30 or 35. On Ultra, back and side photos and PBR materials add 15 each; PBR adds 15 on Text to 3D Pro. Downloads of the result are included. New accounts get 10 free credits, which does not cover an AI model, so you need a plan or a credit pack.
Do I get my credits back if a model fails?
Yes, when the failure is on our side, such as a server error or a job that never starts: the credits return on their own. Photos rejected by the content rules or that the AI cannot read may not be refunded, because the AI service may still bill those runs.
Which file formats can I download?
STL, OBJ and GLB, all at no extra charge. STL and OBJ are scaled to the height you set and hold the shape only. The GLB is the original file: textured from Ultra, Text to 3D Pro and Trellis-2, plain from Pro and Fast.
How long does it take to generate a 3D model?
Usually 1 to 3 minutes, more when many jobs are queued. Each account can run 2 jobs at once, and you can close the page while they run: results stay in My 3D models for 30 days.
Can I sell prints of AI generated 3D models?
Yes. The AI models we run are licensed for commercial use, so models you create here are yours to print and sell. Only upload photos you have the right to use, and do not prompt for characters or brands you have no rights to.
What do back and side photos add?
On Ultra, Multiple images takes the front photo plus optional back, left and right photos. The model then uses real views of those sides instead of guessing them. It adds 15 credits once, however many extra photos you add.
Do I need PBR materials for 3D printing?
No. PBR adds metallic, roughness and normal maps so the model looks right under light in Blender, game engines and viewers. A printed part only keeps the shape, so skip it unless you also need the model on screen. It costs 15 credits on Ultra and Text to 3D Pro.
Should I use text to 3D or a photo?
Use a photo when the object exists: the model follows its shape and proportions. Use text to 3D when it does not, or when you have no good photo. Text gives more freedom and less control, so expect to adjust the prompt. Both start at 25 credits.
