Hi3D

Hi3D is an AI 3D creation service for turning images or text into models, with tools for texturing, reliefs and splitting characters into printable parts. It suits creators who want generation and print-oriented preparation in one workflow. Its breadth is appealing, but the Free plan’s public-model license and small lifetime allowance sharply limit its use for ongoing work.

Overview

Powered by Math Magic’s Sparc3D and Ultra3D models, Hi3D generates 3D models from a single image or multiple views, and also supports text-to-3D. That gives users several ways to start an asset, whether they have reference images or only a prompt. Texturing, relief generation and character splitting extend the service beyond generation; the latter is specifically useful when preparing a character for 3D printing. The trade-off is that plan quotas and licensing matter as much as the feature set.

Key features

• Image and text generation: Single-image and multi-view generation accommodate different reference material, while text-to-3D offers a prompt-led route. The choice is useful for creators working from varied inputs, but each generation draws on a finite allowance.
• Preparation and exports: AI texturing and 3D relief generation support different asset workflows. Models can be exported as FBX, GLB, OBJ, STL or USDZ, a broad selection for users moving models into other tools.
• 3D-printing workflow: One-click character splitting creates printable parts, and models can be sent directly to Bambu Studio or OrcaSlicer. Other integrations include Snapmaker, Creality Print, ElegooSlicer, ComfyUI and Blender. These connections make Hi3D particularly relevant to makers who want generation linked to print preparation; they are less compelling to users seeking only a general-purpose 3D generator.
• Mobile capture and developer access: Hi3D Scan accepts video capture or gallery uploads for 3D model reconstruction. The Open Platform API lets developers and enterprises integrate image-to-3D generation; API operations are priced by model and resolution, with one credit costing $0.020.

Pricing

Hi3D is freemium, with a paid-from price of $19.90/mo. The Free plan costs nothing and provides 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, so this tier is best for limited experimentation, not private or commercial projects.

Pro, Max and Ultra offer private and commercial use, with monthly credits and capacity scaling by tier. Pro includes 1,000 credits/month, up to 100 asset generations/month, 10 concurrent tasks and storage for 200 models. Max raises those allowances to 2,400 credits/month, 240 generations/month, 20 concurrent tasks and 400 models. Ultra provides 8,000 credits/month, up to 800 generations/month, 30 concurrent tasks and unlimited model storage. These tiers suit increasingly intensive workflows, but their plan prices are custom pricing.

Subscription credits reset monthly and do not roll over, so unused allowance is lost at renewal. Purchased Credit Pack credits do not expire, which is a better fit for occasional bursts of work. Monthly and annual billing options are shown for paid plans. Subscription help is available at [email protected]; support options also include Discord, email and dedicated support.

Platforms

Hi3D is available on Android, iOS, web and through an API. That spread supports mobile capture as well as browser-based creation and integration into other products. The service’s privacy policy describes access controls, encryption in transit and at rest where appropriate, and regular security assessments.

Who it's for

Hi3D is a strong fit for 3D-printing users who value character splitting and slicer integrations, and for creators who need multiple generation inputs, texturing or relief tools alongside model exports. Its stated use cases also include game design, film and VFX, art and sculpture, architecture, and fashion and jewelry design. The Free plan is suitable for a small trial; anyone needing private or commercial use should choose a paid plan. Users with production volumes beyond a tier’s generation or concurrency limits should weigh those caps before committing.

Pros and cons

• Pro: Image-to-3D, text-to-3D, texturing and relief generation cover more of the asset workflow than image conversion alone.
• Pro: FBX, GLB, OBJ, STL and USDZ exports, plus direct links to Bambu Studio and OrcaSlicer, serve both broad asset reuse and print-oriented workflows.
• Pro: Paid tiers include private and commercial use, with progressively higher generation, concurrency and storage allowances.
• Con: Free credits are a lifetime allowance capped at 10 generations, and its public CC BY 4.0 models rule it out for private or commercial work.
• Con: Subscription credits do not roll over, and Pro, Max and Ultra use custom pricing, making costs harder to compare against stated quotas.

Verdict

Choose Hi3D if you want image- or text-driven 3D generation with texturing, printable-part preparation and slicer connections in the same service. Its main advantage is that broad creation-to-print workflow; its main drawback is the restrictive public Free tier, while paid plan prices are custom pricing. It is not the best fit for private or commercial use on a no-cost plan, or for buyers who need clearly stated tier pricing before choosing.
