AI3DGen vs SupaVoxel: What the Free Tier and Plans Really Get You
SupaVoxel's Hobbyist plan is $25 a year for 400 credits that last all year, and a textured model costs about $0.19. AI3DGen has a no-account free tier, but its cheapest yearly plan is $84 and its credits reset monthly. Here are the numbers side by side.
- Untextured usually under a minute
- $25/yr vs $84/yr
- Textured: $0.19 vs $0.88 a model

AI3DGen vs SupaVoxel: the short verdict
SupaVoxel is the better pick for most people who want models to print or show. It bundles print-prep tools AI3DGen doesn't list, refunds failed generations automatically, and untextured models usually finish in under a minute. A year of Hobbyist is $25, against $84 for the cheapest yearly AI3DGen plan, and a textured model costs about $0.19 instead of about $0.88. Pick AI3DGen only for a no-account free draft, or if you will spend 800+ credits every month and want face-count and seed controls.
- Lower yearly cost: Hobbyist is $25 for 400 credits valid all year; the cheapest yearly AI3DGen plan is $84 and its credits reset every month
- Cheaper textured models: about $0.19 each on Hobbyist, against about $0.88 for a textured Ultra model on AI3DGen Starter yearly
- Print finishing included in every paid plan from $25 a year, with no extra credits per step: one-click watertight repair, stand base, plane cut with pins, mold generator, multi-color 3MF for Bambu AMS (4 or 16 colors)
- Failed paid runs refund their credits automatically, plus a 30-day money-back guarantee
- Up to 4 extra angles of the same object as input, not just one picture
- A free generator with no sign-up and no card: our test returned an untextured GLB in about a minute
- More raw credits if you use them all: 800 a month on Starter for $7 a month billed yearly
- Hands-on controls on paid plans: face count from 5K to 40K, seeds, steps and poly count
- Image editor and background remover on the same credits
Is AI3DGen really free? What the free generator includes
AI3DGen promises a free 3D model generator with no signup and OBJ, STL and GLB files. The free tier is real: we ran it twice on November 3, 2026 without an account. But its plan details give tighter limits, and our results matched those, not the headline promise.

During our run, the generator warned that free generation usually takes 3 to 5 minutes and showed a queue notice, so expect longer at busy times. Our free mesh had a grainy, lumpy surface. AI3DGen itself shows free models with merged fingers and soft mechanical parts next to paid ones.

|---|---|---|---|---|
| Base model | 20 | $0.30 | about $0.18 | $0.14 |
| Pro model | 40 | $0.60 | $0.35 | $0.28 |
| Ultra, geometry | 80 | $1.20 | $0.70 | $0.56 |

| Background remover | 1 | about $0.02 | about $0.01 | about $0.01 |
AI3DGen gives different credit costs for the same job, Ultra at 60 or 80 and Pro at 38 or 40, so check the number on the Generate button. For comparison, a SupaVoxel textured model is 3 credits: about $0.19 on Hobbyist, $0.14 on Starter and $0.30 pay-as-you-go. An untextured one is 1 credit, about $0.06 on Hobbyist.
Where AI3DGen falls short: free tier, credits and print prep
AI3DGen is cheap to start, but six limits change what you actually get, as of November 2026:
- Free tier: a lighter model than the paid ones, untextured, a daily limit it doesn't publish, queues at busy times, and personal use only. Our free download was a plain white GLB, not the advertised OBJ or STL.
- Credits reset: unused credits are lost at each monthly renewal, and yearly plans still pay them out 800 or 2,000 a month. Credit packs are sold only to subscribers, expire at renewal and are non-refundable.
- Discarded attempts cost you: every attempt spends credits; a verified technical fault returns replacement credits, not money.
- Narrow refunds: a full refund only within 3 days and only if you used no paid credits; a quality refund needs a request within 5 days with proof.
- No print prep listed: AI3DGen lists no one-click watertight repair, no multi-color 3MF for Bambu AMS, no stand base, no plane cut with pins and no mold generator. You finish the mesh in other software.
- Files vanish fast: on Ultra, inputs and models are deleted after one hour.
What it does well: you can cancel any time and keep the plan to the end of the cycle, and every paid plan includes a commercial license.
- Monthly credit reset, even on yearly billing
- No repair, base, cut or AMS 3MF
- 3-day refund window, zero credits used
- Download within an hour
When to pick AI3DGen
AI3DGen is the easier first step if you only want to see a picture become a rough mesh with no account at all, and it suits heavy users who really will spend their credits every month.
- No sign-up for the free generator; our untextured test file was ready in about a minute
- Advanced at $168 a year gives 2,000 credits a month, about 100 Base models
- Face count, steps, chunks, octree resolution and seed controls on paid plans
When SupaVoxel is the better AI3DGen alternative
For most people weighing an AI3DGen alternative, SupaVoxel is the better buy, and the price math shows why. Untextured models usually finish in under a minute and textured ones typically in 3 to 5 minutes. When a generation fails, its credits come back automatically, while on AI3DGen every attempt spends credits and a verified fault returns replacement credits at best.
The yearly bill favors SupaVoxel too. Hobbyist is $25 for 400 credits valid all year, so a textured model costs about $0.19 whether you make 5 this month or 50. On AI3DGen a textured Ultra model is about $0.88 on Starter yearly, and the cheapest yearly plan is $84.
The bigger difference is what happens after generation. A raw AI mesh often has holes, needs a flat bottom, or is too big for the build plate. SupaVoxel's studio does one-click watertight repair, adds a stand base, cuts the model into parts with pins, makes molds, simplifies meshes and exports multi-color 3MF for Bambu AMS. With AI3DGen you would do those steps in other software. If you already have an AI3DGen file, the free STL repair, OBJ to STL and add base to STL tools here work with it, with no account.
- A few prints a month
- Bambu Lab printers with AMS
- Models that need repair or a base
- No monthly reset to race
How to compare AI3DGen and SupaVoxel on the same picture
Pricing only matters if the model is good enough. A fair test takes under an hour and costs nothing.
- 01
Pick two test pictures
One character and one hard-surface object such as a mech or a vehicle, each centered on a plain background, JPG or PNG under 3 MB. Use the same files in both tools. - 02
Run the AI3DGen free generator
Upload without signing in and choose a face count (20K is the default). Download the file from the viewer right away, because files are kept for a short time. Remember this is the lighter free model, not Base, Pro or Ultra. - 03
Run SupaVoxel's free credits
Sign in with Google and upload the same picture to image to 3D. Geometry only is 1 credit, so the 3 free credits cover both pictures with one to spare. Download the GLB. - 04
Inspect both files
Open both files side by side in the free 3D model viewer, or switch to the OBJ viewer if you exported OBJ from a paid plan. Check the back, thin parts like fingers and antennas, and whether hard edges stayed sharp. - 05
Decide what you need to pay for
If you need textures, STL or many models a month, compare a month of AI3DGen Starter with a year of SupaVoxel Hobbyist using the tables above.
SupaVoxel models to weigh against AI3DGen
AI3DGen markets mecha, monsters and game props, so here are SupaVoxel results in the same genres. Each came from one picture; open a card to rotate the 3D file.
Is AI3DGen worth it?
For trying image to 3D with zero commitment, yes. The free generator costs nothing, needs no account and gives you a file to keep. Just treat it as a draft: the free model is lighter than the paid ones, it is untextured, and the license is personal use only.
For paid use, AI3DGen pricing is worth it when you will spend the credits every month. Starter yearly at $7 a month is cheap for 40 Base models a month, but textured Ultra models cost about 100 credits each, so Starter covers roughly 8 of them a month. If you only need a handful of textured, printable models spread across the year, SupaVoxel's $25 Hobbyist plan costs less overall and adds the print finishing tools.
SupaVoxel has limits too: STL, OBJ, USDZ and 3MF exports, textured models and the commercial license need a paid plan, it has no face-count or seed controls, and there is no API.
