Neural4D vs SupaVoxel: the short verdict
SupaVoxel is the better pick if you make up to a few dozen models a month, mostly to print. One $25 payment covers a year, against $166.80 for a year of Neural4D Go, and an untextured model costs about $0.06 against $0.09 on Go yearly. Repair, stand bases, cuts with pins, molds and multi-color 3MF sit in the same studio. Pick Neural4D for hundreds of models a month, FBX, rigging or an API: even at $166.80 a year Neural4D Go costs more per untextured model and only matches SupaVoxel on textured models without PBR; it takes $334.80 or more a year to beat it.
- Lowest yearly bill: $25 for 400 credits valid all year, versus $166.80 for a year of Neural4D Go or $19.90 a month after a half-price first month
- Same or lower cost per model than Neural4D Go: an untextured model is about $0.06 here against about $0.09 on Go yearly; a textured one about $0.19 here against $0.19 without PBR or $0.28 with PBR on Go
- 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). Neural4D charges 30 credits for Smart Multicolor and 40 for part split
- Free browser tools with no account, like STL repair and STL to 3MF
- 30-day money-back guarantee, and failed paid runs refund credits automatically
- A free plan that refills: 50 credits every week, about 20 untextured models a month
- Cheaper credits at volume: about $0.04 per untextured model on the Pro plan
- FBX and .blend exports, plus Normal, Roughness and Metallic PBR maps
- Direct text to 3D, remeshing, part split, AI texturing and rigging in one account
- A developer API with a free key, and up to 200 parallel tasks on Pro

Neural4D's speed is its own claim; we have not timed it. Neural4D also bundles image and video generation and a CAD agent in its paid plans. SupaVoxel's Image Studio handles text to image on the Pro plan, and those pictures can go straight into the 3D studio.

Neural4D pricing vs SupaVoxel pricing, per model
Neural4D charges 10 credits to generate, 10 more for a texture and 10 more for PBR maps. SupaVoxel charges 1 credit for geometry only and 3 for a textured model. Costs below are rounded list prices from November 3, 2026.

Per-model cost only tells half the story. If you make 10 models a year, the cheapest Neural4D plan that lets you download textures still costs $166.80 paid yearly, while SupaVoxel Hobbyist costs $25. Neural4D Plus and Pro are cheaper per model than anything SupaVoxel sells, but only if you pay $334.80 a year or more and really use hundreds of models a month, and they still lack a stand base and mold generator.
Where Neural4D falls short: free plan, billing and print prep
Neural4D is strong for game pipelines, but for hobby and print users these limits matter, as of November 2026:
- A free plan with strings: 50 credits a week (five untextured generations), 8 a day, one task at a time and the slowest queue. Downloads are untextured only and for personal use, and Neural4D says free-plan content enters the public domain.
- Monthly bills with a teaser: the first month is half price, then Go is $19.90 a month. Keeping textured downloads for a year costs at least $166.80 upfront.
- Textures cost extra credits: a texture adds 10 credits and PBR maps 10 more, so a full model is 30 credits, three times an untextured one. Top-ups are sold to subscribers only.
- Print prep is partial: Smart Multicolor (30 credits) and part split (40 credits) are paid extras, and Neural4D lists no stand base or mold generator.
SupaVoxel's free tier is smaller, 3 credits once, but it runs the same generator paid plans use and gives you a GLB to download. Check it in the free 3D model viewer before you spend anything.
- Free: untextured, personal use, public domain
- Half-price first month, then $19.90
- Texture +10, PBR +10 credits
- No stand base or mold generator
When Neural4D is the better choice
Neural4D is built for bulk generation and game pipelines. It exports FBX and native .blend files, adds Normal, Roughness and Metallic maps, and lets you remesh, retexture and rig without leaving the site. On Plus and Pro the per-model price drops below SupaVoxel's, up to 200 tasks run in parallel, and developers get an API with a free key. Those savings start only at $334.80 a year, though, and Neural4D advertises about 90 seconds per model.
- FBX, .blend and PBR maps for game engines
- Rigging, remeshing and an API
- Hundreds of models a month
When SupaVoxel is the better Neural4D alternative
SupaVoxel suits makers who print a few models a month. Untextured models usually finish in under a minute and textured ones typically in 3 to 5 minutes, failed generations refund their credits automatically, and the 30-day money-back guarantee covers your first purchase.
The Hobbyist plan is $25 for the whole year, with 400 credits that stay valid all year and no monthly bill to forget. That is $141.80 less than a year of Neural4D Go, and an untextured model costs about $0.06 instead of $0.09.
After generation, the studio has one-click repair to a watertight manifold solid, a stand-base generator, plane cut with alignment pins, a mold generator and multi-color 3MF for Bambu AMS with 4 or 16 colors matched to the Bambu PLA palette. Neural4D sells multicolor and part split as extra-credit steps, and lists no bases or molds.
If you only need a print-ready file from one photo, start at image to STL. For colored prints, see the multicolor 3D print guide.
- A few models a month, paid once a year
- Prints on Bambu Lab printers with AMS
- Bases, pins and molds in the same studio
- 30-day money-back guarantee
How to test Neural4D and SupaVoxel on the same picture
Plans only matter if the model is good enough. A fair head-to-head takes about half an hour and costs nothing.
- 01
Choose two test pictures
One character and one hard-surface object, each centered on a plain background. Use the same files in both tools, and keep them under 5 MB so Neural4D accepts them. - 02
Generate in Neural4D
A free account's 50 weekly credits cover five untextured models. Download the mesh and note how long each one took. - 03
Generate in SupaVoxel
Upload the same picture to image to 3D. New accounts get 3 free credits; geometry only is 1 credit. Untextured models usually finish in under a minute. - 04
Compare in a viewer
Open both files in the free 3D model viewer. Check the back, thin parts and fingers, then count holes with STL repair. - 05
Slice the winner
Export STL or 3MF and open it in your slicer. If you go with SupaVoxel, the Bambu Lab guide covers supports and AMS colors.

Is Neural4D worth it?
For a studio or a heavy user, often yes. Neural4D Pro at list price buys 25,000 credits a month for $99.90, which works out to about 12 cents for a textured model with PBR maps, and the plan adds 200 parallel tasks, rigging, remeshing and an API. If you sell custom assets every day, that capacity matters more than the monthly bill.
For occasional use the math flips. The cheapest Neural4D plan that lets you download textures and use models commercially is $166.80 a year paid yearly, or $19.90 a month. SupaVoxel Hobbyist is $25 a year. SupaVoxel has limits you should know: textured models, STL, OBJ, USDZ and 3MF exports and the commercial license need a paid plan, there is no FBX export, no rigging, no API, and text to 3D goes through Image Studio on the Pro plan.
