Hi3D V3.0 raises AI 3D models to 2048³ voxel resolution. 48-hour free trial
Hi3D has released V3.0 of its all-in-one AI 3D model generator, which now builds geometry at 2048³ voxel resolution. That is up from 1536³ in the previous version, or 2.37 times the voxel count, and texture output goes up to 8K. The company has also reworked its cross-view structural reasoning and its UV completion algorithm.
Those three changes target the stages where detail is most often lost between the source image and the finished asset. This in turn reduces manual mesh repair before a model enters a production pipeline, in gaming, film, 3D printing and industrial design.
To mark the launch, Hi3D is offering free access to V3.0 for 48 hours, running from 00:00 UTC on August 19, 2026 to 24:00 UTC on August 20, 2026 at www.hi3d.ai. During the same window, annual plans are available at 70% off.
2048³ voxel resolution
Lower resolutions merge neighboring detail and blur sharp transitions. Until V3.0, layered feathers and scales, lettering and logo edges, and mechanical junctions have needed manual repair. At 2048³ those separate cleanly, and the finer grid picks up shallow engraving and surface relief. Hi3D says thin walls and unsupported overhangs also come through intact.

Structural stability
When you upload a 2D image you of course only see the one angle, but to print in 3D you need all of them. The hidden regions and the way parts meet have to be inferred, and that is where errors tend to concentrate. V3.0’s refinement step targets those areas, along with points where objects intersect. According to Hi3D, geometry stays stable and supported even when the rear and side views are obscured.

8K textures
V3.0 raises maximum texture output to 8K, paired with an updated version of Hi3D’s UV completion algorithm. The company reports cleaner pattern edges, smoother color transitions and finer ornamentation even under extreme magnification.

Production-ready
V3.0 carries over the tools that take a generated model to a printable state: Split for 3D Printing, Multicolor 3D Printing and Auto-Plating. Together they remove the separate modeling step that usually sits between a generated mesh and a working print file.
That combination of tools points at where Hi3D is aiming V3.0: to give professional and casual users alike editable, presentable assets to build on, without requiring any prior 3D modeling experience.
From V1.0 to V3.0
Hi3D, previously known as Hitem3D, launched V1.0 in July 2025, billed by its developer as the world’s first AI 3D generation tool to support 1536³ resolution from a single image. V2.0 unified geometry and texture generation, added mapping for occluded structures, and refined texture de-lighting. V3.0 raises resolution to 2048³ and reworks the steps that handle what the source image does not show.

Geometry that needed manual repair before it could be printed, cast or machined can now go further into a production workflow without that intervention.
