How Long Does Image to 3D Generation Take?
Real generation times per tier: about 30s on Quick and about 2 to 4 minutes on Precise, and why the estimates come from live completion data.
Short answer
MakeIt3D offers two tiers. Quick finishes in about 20 seconds and costs 1 credit. Precise takes about 2 to 4 minutes and costs 3 credits. These are measured numbers, not estimates. Across 5,969 completed generations in the 90 days to 6 August 2026, the median Quick generation finished in 19.96 seconds, and 9 in 10 finished within 31.81 seconds. The median Precise generation finished in 144.94 seconds, with 9 in 10 within 251.11 seconds. Those figures are end to end and include queue time. The app also shows a live estimate before you generate, based on recent completions and current load. The tiers differ because they run different AI models. Quick is tuned for speed, so it is the right choice for testing a photo or a crop. Precise runs a heavier reconstruction that builds PBR materials and up to 500,000 polygons, which is why it takes minutes rather than seconds. Use Precise for final assets and prints.
What happens during those seconds
A generation is more than one AI call. This is the pipeline and the time at each tier.
Upload and preprocessing
The app uploads your photo and removes the background before the reconstruction. So the AI works from a clean outline, not the whole scene. This step adds a few seconds and improves the geometry.
The estimate you see is measured, not fixed
The app measures the estimate. It does not fix it. The app averages the last 20 completed generations for your tier. It subtracts the queue time. It discards the outliers: more than 2 minutes for Quick, or 15 minutes for Precise. It then adds about 8 percent for each active generation, up to a 1.5x limit. It adds 30 seconds if the tier is cold.
Quick: about 30 seconds
Quick runs the TRELLIS model for 1 credit. It uses a 1,024-pixel texture and light mesh simplification. Use Quick to test several photos or crops before the final render.
Precise: about 2 to 4 minutes
Precise runs Hyper3D Rodin v2 for 3 credits. It builds up to 500,000 polygons with PBR materials. This needs much deeper geometry and texture work. Use Precise for final models and prints, not for tests.
Delivery and download
The finished model loads into the browser viewer as a GLB. Your browser converts it to STL, OBJ, or 3MF at download time. So a change of format adds seconds, not another generation.
FAQ
Why does Precise take up to ten times longer than Quick?
Precise runs a heavier model. Hyper3D Rodin v2 builds up to 500,000 polygons with PBR materials. The Quick TRELLIS pass is tuned for speed with a smaller texture. You can see the difference on faces, fine detail, and print quality.
Do multiple photos make generation slower?
No, not by much. A generation with up to 4 photos takes about the same time as a single-photo generation on the same tier. It also costs the same number of credits.
Why did the estimated wait change between visits?
The app computes the estimate again from the recent generations and the current load. A busy period raises it by up to 50 percent. The first generation after a quiet hour can add about 30 seconds for the model warm-up.
What is the fastest way to iterate on a model?
Test your photos and crops on Quick. Each test costs 1 credit and takes about 30 seconds. Then run only the best photo on Precise. This costs less and is much faster than tests on the 2-to-4-minute tier.
Does downloading in a different format add wait time?
Only a few seconds. The app stores the model as GLB. Your browser converts it to STL, OBJ, or 3MF when you download. There is no server request and no credit cost.
