Meshy, the AI 3D model generator built by Tsinghua and MIT graduate Yuanming Hu, started in 2023 as a tool for game developers. Since Meshy-6 it has added slicer exports, mesh repair and build-plate splitting aimed at 3D printing, with Bambu Lab, Creality, Elegoo, FlashForge and xTool listed as customers and a direct send button to Formlabs’ print service. The company raised nearly $400 million in a Series B in July 2026 at a $1.5 billion valuation, and claims over 12 million registered users and more than 100 million generated models.
3Dnatives’ lab tested the current model, Meshy-7.1, by feeding it nine inputs, a mascot photo, a Jacob & Co. Astronomia watch, a Seiko 5 Sports GMT shot from multiple angles, a Ligier JS2 R race car from three press photos, a cathedral, and three AI-generated images, then examined the exported 3MF files directly rather than printed parts.
The mascot came out cleanest: a single watertight solid at 385,000 triangles, though Meshy copied visible 3D-print layer lines from the source photo into the geometry as ridges. The Ligier came out as one closed 778,000-triangle body, about 7% too wide and 3% too tall against the real car’s 4,415 by 1,900 by 1,180 mm dimensions, with all body lettering turned into unreadable shapes. The Astronomia watch split into 35 separate bodies, several planets lost the stalks holding them to the dial, and Meshy invented a full strap, buckle and keeper for a section the photo never showed.
Meshy’s own May 2026 benchmark, slicing 75 models from five generators at 15 per tool in Bambu Studio, claims about 97% of figurine-type models pass validation, a figure 3Dnatives notes is not a whole number at that sample size and was the specific claim it set out to check.
