Hi3D

Hi3D suits creators who want to turn references or prompts into 3D assets and carry them toward printing or other production workflows. Its generation, texturing and export tools make it a flexible starting point, but the free plan’s small lifetime allowance and public-model license sharply limit its usefulness for ongoing work.

Overview

Hi3D is an AI 3D creation platform powered by Math Magic’s Sparc3D and Ultra3D models. It generates models from a single image or multiple views, and also supports text-to-3D. Rather than stopping at generation, it adds texturing, relief creation and character splitting for printing. That breadth is valuable when one service needs to cover several steps, though it does not remove the need to consider quotas, licensing and the rest of a production workflow.

Key features

• Image and text generation: Single-image and multi-view input accommodate different reference material, while text-to-3D gives users a route from a prompt when no image is available. The choice is useful for concept creation, but monthly generation allowances still constrain volume on paid plans.
• Model preparation: AI texturing and 3D relief generation extend Hi3D beyond basic conversion. One-click character splitting into printable parts is particularly relevant to 3D-printing projects; it matters less to users who only need a model for game, film or visual-design work.
• Export and printing connections: Models can be exported in FBX, GLB, OBJ, STL and USDZ, giving creators options for different downstream uses. Direct sending to Bambu Studio and OrcaSlicer, alongside integrations that include Snapmaker, Creality Print, ElegooSlicer, ComfyUI and Blender, makes Hi3D more practical for workflows that use those tools.
• Developer access: The Open Platform API lets developers and enterprises integrate image-to-3D generation into their products. API generation is priced by model and resolution; the documented rate is $0.020 per credit, so API users should account for operation-specific credit costs.
• Mobile capture: Hi3D Scan supports video capture or gallery upload for 3D model reconstruction. This gives mobile users a separate capture route alongside the platform’s image and prompt generation.

Pricing

Hi3D uses a freemium model, with paid plans starting at $19.90/mo. Free costs nothing and includes 100 lifetime credits, up to 10 asset generations, one concurrent task and storage for up to seven models. Models are public under CC BY 4.0. That makes Free suitable for limited exploration, not for private or commercial work, and its lifetime allowance is easy to exhaust.

Max, Pro and Ultra show monthly or annual billing options, but their prices are custom pricing. Max includes 2,400 credits/month, up to 240 generations/month, 20 concurrent tasks and storage for up to 400 models. Pro includes 1,000 credits/month, up to 100 generations/month, 10 concurrent tasks and storage for up to 200 models. Ultra includes 8,000 credits/month, up to 800 generations/month, 30 concurrent tasks and unlimited model storage. All three paid plans include private and commercial use.

Pro is the lower-volume paid option for users who need private or commercial use without Max’s larger quota. Max increases generation capacity and concurrency; Ultra is for heavier workloads or users who need unlimited storage. Subscription credits reset monthly and do not roll over, so unused allowance is lost. Purchased Credit Pack credits do not expire. Support options across the plans include Discord, email support and dedicated support; subscription help is available at [email protected].

Platforms

Hi3D supports Android, iOS, web and API access. Its combination of mobile apps and web access suits creators who want to work across devices, while the API is aimed at teams integrating generation into other products.

Who it's for

Hi3D is a sensible fit for 3D-printing creators who value model splitting and slicer connections, as well as people exploring game design, film and VFX, art and sculpture, architecture, or fashion and jewelry design. The wide export selection supports varied downstream workflows. It is a weaker fit for anyone who needs a generous free allowance, private use without a paid plan, or predictable API costs without evaluating each operation’s credit price.

Pros and cons

• Pro: Image, multi-view and text generation provide several starting points for creating an asset.
• Pro: Texturing, relief generation and printable-part splitting add practical preparation tools beyond model generation.
• Pro: Five export formats and connections to printing and 3D software support varied workflows.
• Con: Free use is capped at 100 lifetime credits and 10 generations, with only seven saved models and one concurrent task.
• Con: Free models are public under CC BY 4.0; private and commercial use require a paid plan.
• Con: Paid-plan prices are custom pricing, and subscription credits expire at each monthly reset.

Alternatives

For a broader comparison, see AI 3D Model Generators.

• Polar Cloud is a freemium option for printer workflows; its Free plan covers one printer, five print jobs per month, seven-day history and 300 MB of storage, but limits files to mesh formats and 30 MB.
• Meshy is another freemium option on Android, API, iOS and web, with a Free plan offering 100 credits and 10 monthly downloads for Meshy 6 Lite models.
• Stable Fast 3D is a paid option with a free Community License for research and non-commercial use, plus commercial use for organizations with annual revenue of $1,000,000 or less.
• Polycam may suit mobile capture workflows: it runs on Android, iOS and web, and its Free plan includes limited space, object and AI captures, GLTF exports and public link sharing.
• Unique3D offers a free online demo that requires a registration invitation code.
• Crisp3D is a web-based freemium alternative whose Free plan limits users to one concurrent task and public models, with a non-commercial license and no downloads.
• Sloyd is a web and API alternative with a Guest plan allowing one 3D generation per day.
• Hyper3D Rodin is another freemium alternative for web and API.

Verdict

Choose Hi3D if you want image- or prompt-led 3D generation with useful texturing, printing preparation and export options in one platform. Its clearest advantage is that workflow breadth; its main drawback is that the free tier is too limited and public for sustained private or commercial projects. Creators who need those rights should budget for a paid plan, while those seeking a different capture or printer-management focus should compare the alternatives.
