What is the 3D figurine trend, and can you print one?

Both waves started with an image model. In April 2025, people used OpenAI's 4o image generation to make themselves into boxed action figures with accessories and job themed packaging. In September 2025, the figurine version took over after Google shipped Gemini 2.5 Flash Image on 26 August 2025 and called it nano banana in its own launch post.

Google later published the prompt people were using. It asks for a 1/7 scale commercialized figurine of the person in the picture, standing on a round transparent base on a desk, with the toy's box behind it. The result is a picture of a figurine. There is no 3D file behind it.

On Google Trends, worldwide searches for nano banana went from nothing in the first week of August 2025 to the highest point on the chart five weeks later. Today they sit at about a tenth of that peak. On the same chart, the April 2025 action figure wave peaked at 9 out of 100.

A picture shows one side. Software that turns one photo into a 3D shape has to make up the side you can't see, and the researchers who build these models use the word hallucinate for it. A print file also has to be a closed surface. The 3MF format that full-color printing uses requires a continuous surface without holes, gaps or open edges.

Every part also needs real thickness. A drawn pair of glasses can be as thin as a line, and a printed pair has to survive cleaning and shipping. Our figurines are printed by JLC3DP in full-color resin, and the table below shows the limits it publishes. Protolabs, an independent manufacturer that uses the same kind of printing, publishes 0.76 mm as its thinnest free standing wall, which is close to JLC3DP's 1.0 mm.

So a real figurine takes a second step after the picture. Someone has to build a 3D model that is closed, thick enough everywhere, and inside the printer's size limits.

Every Nendo figurine goes through this step, so we can measure it. Since 1 July 2026, 96 in 100 uploads reached a finished 3D model, measured on 455 runs. Half were ready in 5.1 minutes and 95 in 100 inside 10 minutes. The picture is redrawn in the Nendo style in about 104 seconds, and then the 3D model is built in about 176 seconds.

We build every figurine from the redrawn picture and never from the file you upload. The redrawn picture is made so the 3D step can build a front and a back that match. Most uploads that fail are pictures the AI image filter refuses. That was 3.2% of all uploads since 9 May 2026, and you find out in about 2 minutes.

Thickness is the problem that shows up later. None of the AI 3D generators we tested lets you set a minimum wall, and asking for it in the prompt didn't help. Four new tries on one model still came back with rims of 0.3 to 0.4 mm, and the printer needs 1.0 mm. In August 2026 the printer sent three of our orders back for this. The parts were glasses arms, a dog collar tag, and shoelaces and straps, and the thinnest measured 0.43 mm. We redrew those parts thicker and rebuilt the models. They came out at 1.42 to 1.53 mm and printed.

On 17 September 2026 we asked an OpenAI model with web search the same questions twice. Most answers had no sources, and the two runs didn't agree with each other.

One run said there is no reliable public failure rate for AI figurine services, and then gave a table of odds anyway. The second run gave different odds. The table below puts those answers next to what we measured.
