print3dgs

print3dgs is a Shanghai service that prints a 3D Gaussian Splatting model as a full colour object in transparent resin. It is operated by Sparseetech (Shanghai) Co., Ltd., 稀树科技（上海）有限公司, which was founded in May 2025 and which also runs DenseWorld, a public gallery where users publish and browse captured 3D scenes. The company dates its first working demo to July 2024, its first published articles to January 2025 and its first international conference paper to April 2025. Its first closed beta finished in July 2026 and its user agreement took effect on 1 July 2026.

The distinguishing claim is that no mesh is produced at any stage. The usual route from a radiance field to a physical object runs through a watertight mesh, which is then printed in a single material and painted, or printed with surface colour deposition, and Kiri Engine's 3DGS to Mesh 3.0 is one example of that conversion step. print3dgs voxelizes the Gaussians and deposits colour throughout a clear resin block instead, so per point colour is carried inside the volume rather than baked onto a surface. Thin structures and translucency survive the trip that a mesh conversion flattens. The idea of printing splats rather than meshes has been circulating since 2025.

The workflow is a browser studio. A user uploads a 3DGS .ply file, adjusts pose and colour, sets the shell shape and size, sees a live quote, and orders. Files are stored in the cloud for preview, editing, quoting, printing and after sales support, and the terms restrict Sparseetech to that scope, with an explicit undertaking not to train publicly released generative models on individually identifiable user assets. The studio preview is a 3DGS render rather than a render of the solid, and the company says plainly that it should be used only as a guide to composition and proportion. Registration currently requires a mainland China mobile number and an SMS code, which is the practical limit on who can order.

The algorithm is at v0.1 beta and Sparseetech publishes its limits rather than hiding them. Because the finished piece is refracting resin, the top and bottom faces read clear while the four side faces show a local blur once the viewing angle tilts roughly twenty degrees above or below head on. Colour shifts because the resin gamut and a monitor gamut do not match. Residual floater points in the source data get printed along with everything else when the capture lacks viewpoints. Thin sheet geometry such as a lotus leaf comes out translucent and loses its solid feel.

Subject choice matters more than it does with mesh printing. Sparseetech reports that fur and hair, dense complex geometry such as dandelion heads and mineral ore, and genuinely translucent subjects such as bottles all print well, since each of those plays to a volumetric colour medium. Highly saturated colours tend to wash toward white, and aerial terrain captures come out thin and transparent overall. The published sample set covers a dandelion, a transparent bottle, hair, a front facing portrait, a plush toy, an ancient pagoda, a tree canopy, a lotus leaf, a large scene architectural capture, mineral ore, a statue and an anime figure.

Prints are made to order, so the terms exclude them from China's seven day no reason return right except where a legal right applies or the piece is faulty. Obvious defects such as fracture, gross colour deviation or a wrong item are handled by reprint or exchange on presentation of photographs. Sparseetech reserves the right to refuse designs for restricted or controlled items.
