Overview

Fast3D is an AI-powered 3D model generator that turns text prompts or images into 3D assets through a browser-based workflow. The site positions it as a tool for creating models quickly without requiring traditional 3D modeling software.

The product supports text-to-3D and image-to-3D generation, with options for single-image or multi-view input and several quality settings. It also includes export support for common formats such as GLB/GLTF, FBX, OBJ/MTL, and STL, plus a separate online 3D viewer for inspecting files in the browser.

Features

Text and image input

Create 3D models from text prompts, single images, or multiple images, with the interface offering both text-to-3D and image-to-3D workflows.

Fast generation workflow

Generate models in 10 seconds according to the site, with simple settings that let users choose between different quality levels.

Quality controls

Adjust texture and mesh density settings before generating, including options such as Fast, Standard, Pro, and Ultra.

High-precision geometry generation

Produce high-precision geometry designed to capture detailed contours and structural accuracy for more realistic model output.

Multiple export formats

Export finished models in GLB/GLTF, FBX, OBJ/MTL, and STL formats for use in 3D software, game engines, and printing workflows.

Browser-based 3D preview

View uploaded 3D files in the browser with rotation, zoom, pan, fullscreen, and support for common formats through the included 3D viewer.

Use Cases

Concept-to-asset creation
Generate a 3D asset from a written prompt when you want to move from concept to a model quickly without opening traditional modeling software.
Image-based model generation
Upload one image or multiple views to produce a 3D model when you already have reference art or product photos.
Cross-format export for production use
Create output in formats such as STL for printing or GLB/FBX/OBJ for downstream 3D software and game workflows.
Browser review and inspection
Preview, rotate, and inspect 3D files directly in the browser before handing them off to another tool or workflow.
Evaluation before subscription
Use the free tier to try the generator before choosing a paid plan with higher or unlimited generation limits.
