Open model from Microsoft
TRELLIS.2 has about 4 billion parameters. Microsoft released the code and weights under the MIT license, with the paper Native and Compact Structured Latents for 3D Generation. See microsoft/TRELLIS.2 on GitHub.
TRELLIS.2 Image to 3D Model
Run Microsoft's open TRELLIS.2 model on one photo and get a textured 3D model. Pick 512, 1024 or 1536 resolution for 25, 30 or 35 credits, check it in 3D, then download STL, OBJ or GLB at no extra cost.
Resolution
Texture size
TRELLIS.2 builds a textured 3D model from one photo. Higher resolution keeps finer detail.
Credits come back automatically if a generation fails on our side.

Inspect the textured GLB, shrink it for the web, or check the STL before you slice.
What is TRELLIS.2?
An image to 3D model from Microsoft, published with its code and weights in December 2025.
One image in, textured mesh out
It reads a single image and builds the full object as a mesh with a baked color texture. Here you get that as a GLB, plus STL and OBJ exports for printing.
Made for complex shapes
Microsoft designed its O-Voxel structure to represent open surfaces, sharp edges and enclosed inner parts, such as clothing or leaves.
Best with one clear object
Like any single-image model, it guesses the sides it cannot see. It does best with one object on a plain background: figurines, toys, props, furniture and game assets.
How to use TRELLIS.2 here
- 1
Add one photo
Upload a PNG, JPG or WebP photo of a single object. A plain background gives the cleanest result.
- 2
Pick resolution and texture
512, 1024 or 1536 for 25, 30 or 35 credits, plus a texture size. Credits are taken when the job starts, and a model is usually ready in 1 to 3 minutes.
- 3
Preview, size and download
Turn the model in the 3D preview, set its height in millimeters, then download STL, OBJ or GLB at no extra cost.
Which resolution and texture size to choose
Resolution sets how much shape detail the model can hold, and a higher one takes longer. Texture size only changes the color image.
512 resolution
The quickest and cheapest run. Good for a first try, simple shapes and small prints, where extra detail would be too small to print. Texture 1024 or 2048.
25 credits1024 resolution
A balance of detail and time for most figurines, toys and props. Texture 1024, 2048 or 4096.
30 credits1536 resolution
The most shape detail and the longest wait. Worth it for large prints, faces and fine surface detail such as fur, folds or carving. Texture 1024, 2048 or 4096.
35 creditsTexture size
The size of the color image wrapped around the model. A bigger texture keeps finer color detail and makes a larger GLB. It does not change the shape, so a single color print looks the same.
Same pricePreparing a photo for TRELLIS.2
Four checks before you spend credits. Each one removes something the model would otherwise have to guess.
One object, whole in frame
Center one object with a little space around it. Cut-off ears, feet or handles come back missing, and a second object can merge into the first.
A plain background
Use a bare wall or a sheet of paper, or remove the background first. Clutter behind the object can turn into extra geometry.
Front or 3/4 view at mid-height
Hold the camera level with the middle of the object. A slight 3/4 angle shows one side too; top-down shots and pure side views hide too much.
Soft light, sharp focus
Window light or an overcast day, with no hard shadows or glare, which get read as shape and painted into the texture. Use a sharp photo, not a small thumbnail.
From a TRELLIS.2 GLB to a printable STL
The GLB is made for screens. These four steps turn it into a print.
Set the height in mm
A photo has no real scale. Type the height you want (10 to 300 mm) and the STL and OBJ are scaled to it. The GLB stays as generated.
Download the STL
STL keeps the shape only, which is all a slicer needs. Keep the GLB if you want the colors for Blender, a web viewer or as a painting reference.
Give it a flat base
If the bottom is rounded, cut 1 to 2 mm off with your slicer's cut tool, or stand the model on a small plinth, so it sits firmly on the bed.
Check thin parts and errors
Parts under about 0.8 mm may not print on a 0.4 mm nozzle, so scale up or thicken them. Microsoft notes raw meshes can have small holes; if your slicer reports errors, run its repair.
TRELLIS.2 or Hunyuan3D Pro and Ultra?
All three build a full 3D model from a photo, and none wins on every photo. They differ in what you control and what you get back.
TRELLIS.2 (this page)
One photo. You choose the resolution (512, 1024 or 1536) and the texture size, up to 4096. Always textured. Pick it when you want control over detail.
25 to 35 creditsPro: Hunyuan3D v3.1 Rapid
One photo, returned as an untextured mesh made for printing. Pick it when you only need the shape for a single color print. Try it in the AI 3D model generator.
25 creditsUltra: Hunyuan3D v3.1 Pro
A textured model. Add back and side photos (+15 credits) so those sides are not guessed, and PBR materials (+15). Pick it for objects whose back matters. Try it in the AI 3D model generator.

Answers about the model, credits, settings, printing and refunds.
What is TRELLIS.2?
TRELLIS.2 is an image to 3D model from Microsoft with about 4 billion parameters. It turns a single image into a textured 3D mesh. Microsoft published the paper, code and weights in December 2025 under the MIT license.
Is TRELLIS.2 free to use here?
No. The model is open source, but running it needs a GPU with at least 24 GB of memory, so here each run costs credits: 25 at 512, 30 at 1024 and 35 at 1536 resolution. Downloading the result as STL, OBJ or GLB costs nothing extra. New accounts get 10 free credits, which is not enough for a TRELLIS.2 model.
Which resolution should I choose?
Start with 512 for a quick test or a small, simple print. Use 1024 for most figurines and props, and 1536 for large prints or fine surface detail such as faces, fur or carving. Higher resolutions take longer.
What does texture size change?
Only the color image wrapped around the model: 1024 or 2048 at 512 resolution, up to 4096 at 1024 and 1536. A bigger texture keeps finer color detail and makes a larger GLB. It does not change the shape or the price, and an STL has no color at all.
Can I use more than one photo?
Not with TRELLIS.2: it builds the model from one image. If you have back or side photos, use Ultra in the Image to STL tab on the homepage and choose Multiple images, which adds 15 credits.
Can I 3D print a TRELLIS.2 model?
Yes. Set the height in millimeters, download the STL and open it in your slicer. Flatten a rounded base with the cut tool, thicken or scale up parts thinner than about 0.8 mm, and add supports under overhangs. If the slicer reports mesh errors, run its repair.
Should I use TRELLIS.2 or Hunyuan3D?
Use TRELLIS.2 when you want to choose the resolution and texture size. On the homepage, Pro (Hunyuan3D v3.1 Rapid, 25 credits) gives an untextured mesh for printing, and Ultra (Hunyuan3D v3.1 Pro, 35 credits) gives a textured model and can use back and side photos. No model wins on every photo, so a second try with the other can help.
How long does it take, and what if it fails?
Usually about 1 to 3 minutes, longer when the queue is busy, and up to 2 jobs can run at once. Finished models stay in My 3D models for 30 days. If a job fails on our side, the credits come back automatically; images rejected by the content rules or that cannot be read may not be refunded.
