If you came looking for an stl viewer, this comparison helps you judge whether Tripo AI produces usable 3D-printable geometry and how its credits compare with SupaVoxel.
This is an independent test. Nothing here came from vendor access: both tools were used on my own free and paid accounts.
My verdict in 60 seconds — Tripo 58/100, SupaVoxel 90/100
One photograph of a desktop robotic arm, run once through Tripo and once through SupaVoxel at stock defaults, with the credit balance on screen before and after each step. I bought the credits on both sides myself. Both products passed every part of the geometry test on this subject — real through-holes, a surviving cable, flat parallel plates. That is the unusual part, and it is what makes the money question the whole question: Tripo charged 55 credits and SupaVoxel charged 3 for an outcome that ties. 18.3×.
- Credits for one arm — Tripo 55 · SupaVoxel 3 · 18.33×
- When you are charged — Tripo on submit, balance 755 → 700 while the card still said Generating · SupaVoxel on submit, 337 → 334 · both charge up front, so abandoning mid-run refunds nothing on either side
- When the price is shown — Tripo after upload, the button reads only "Generate" before that · SupaVoxel before upload, the button reads "Generate (3 credits)" on an empty workbench
- Credits for a batch of 100 — Tripo 5,500 · SupaVoxel 300 · 5,200 credits apart
- Wall clock, this arm — Tripo 175.0 s · SupaVoxel 139.6 s · SupaVoxel 35 s quicker on this one run
- Wall clock across the ten subjects I ran — SupaVoxel is usually faster (quicker on 7 of 10, median 133.6 s against 163.5 s) and Tripo is far more predictable (135–189 s, a 54 s spread, against 100.2–867.4 s and 767 s). Two different things, and you need both to choose.
- Resin for 100 arms at 120 mm — Tripo $877.00 · SupaVoxel $815.00 · only $62 apart
- Trial-limited switches on Tripo's screens — Clean Topology ×2, Generate in Parts ×1, 8K Texture ×1
- Download for a batch of 100 — Tripo 6.29 GB · SupaVoxel 0.56 GB
Three things before the detail. Tripo's 55 credits did not turn into material: $8.77 against $8.15, a gap of $0.62. Tripo does not tell you the price until the image is already uploaded. And on timing the two split the difference: SupaVoxel was quicker on 7 of my 10 subjects, while Tripo was the one that never had a slow run — both figures are below, because either alone is misleading.
For a workshop making this arm, once or a hundred times, I would use SupaVoxel — same three passes, 1/18.3 of the credits, and a batch that downloads in half a gigabyte instead of six.
The single input, 1,403,490 bytes. Flat link plates with cut-out windows and a three-strand servo loom — a hard-surface subject with nothing hidden. Both products received this file byte for byte and both were left on product defaults.
The price is on SupaVoxel's button before you upload; on Tripo's only after
On an empty SupaVoxel workbench the primary button already reads "Generate (3 credits)" and the balance sits in the top bar at 337. You know the cost before you decide to spend it.
Tripo's home screen shows a balance of 755 and a button that reads "Generate". No number. Upload the reference image and the same button becomes "Generate 55" — so the only way to discover what a Tripo run costs is to hand over the file first. Second-order number: the information you are missing at that moment is worth 52 credits.
SupaVoxel, empty studio. The price is written into the button — Generate (3 credits) — and the balance reads 337. The reference slots take Main plus four extra angles; this case used one. Also visible: SupaVoxel's own two-step onboarding bubble sitting in the middle of the viewport. It is not a zero-popup product, only a two-step one.
Tripo, home. Balance 755, button reads "Generate" with no price. The quality selector offers Best Quality and Clean Topology, and Clean Topology is labelled Trial ×2 on the control itself. A personal-brand promo bubble floats top right, notification badge at 99+.
Tripo after upload: the button now reads Generate 55. This is the first and only place the price appears before you commit.
SupaVoxel after upload: the button text has not changed one character. Still Generate (3 credits). The price does not float with the input.
Clean topology is a trial on Tripo, and that matters here
Tripo's quality selector marks Clean Topology as Trial ×2 on the control. I left the run on Best Quality, the default, because the point is to measure what a normal user gets.
That matters downstream. The Tripo mesh I received has inconsistent winding — the normals have to be flipped before it slices — and the route to avoiding that is the trial-limited switch. The repair step is not a bad roll; it is the standard behaviour of the default tier, and the fix has a counter on it.
Two more switches sit in Tripo's Members Only column and only become visible on the generation screen: Generate in Parts (Trial ×1) and 8K Texture (Trial ×1), both off. So three of the switches that could change the result are metered, and you learn what you did not buy after the 55 credits are gone. Separately, the completion screen advertises Free Retry (×3) — a retry allowance, not a quality switch, and I am not counting it among the three.
Tripo, verification frame — near pixel-identical to the previous shot, thumbnail present, button still Generate 55. I took it because Tripo's upload has a history of failing silently and the only tell is that number on the button.
Tripo charges on submit: 755 → 700 while the card says Generating
The generation screen settles the billing question. Tripo's balance has already dropped from 755 to 700 — the full 55 — while the result card still reads "Generating... 107s". Abandon there and you have paid.
SupaVoxel does the same thing: its balance goes 337 → 334 at submit, exactly 3. The difference is not the policy, it is the size of the bet. Second-order number: three abandoned Tripo runs cost 165 credits, which is 55 SupaVoxel generations.
Tripo mid-run. Balance already 700. Three things are competing with the model for the viewport: a Humanoid Rigging & Text2Motion promo bar across the top, a View Your Model tutorial panel covering the right half, and the Members Only column with two trial switches that were never offered before payment.
SupaVoxel mid-run. One progress bar at 3% and the line "Estimated 5-10 minutes". No promo bar, no tutorial panel over the model.
Wall clock: SupaVoxel is usually quicker, Tripo is never slow
On this arm Tripo took 175.0 s and SupaVoxel 139.6 s. Tripo shows no completion timestamp, so I bracketed its run with a check on the result card every 30 seconds; SupaVoxel's own timer gave me the 139.6 s directly.
The ten-subject picture needs two sentences, and quoting either one alone would mislead you. SupaVoxel was the quicker of the two on 7 of the 10 subjects, with a median of 133.6 s against Tripo's 163.5 s — roughly 30 s a run. And Tripo was far more predictable: every Tripo run landed between 135 s and 189 s, a 54 s spread, against SupaVoxel's 100.2–867.4 s, a spread of 767 s.
The tail is where that matters. SupaVoxel's slowest three were the tank at 867 s, the reindeer at 258 s and the watch stand at 250 s; Tripo has nothing in that territory because Tripo has no territory — it spends the same time on everything, the same way it spends the same triangle budget on everything. So: if you are generating one model and watching the tab, SupaVoxel usually hands it back sooner. If you are queueing a batch against a deadline, Tripo's 54 s window is the thing you can plan around and SupaVoxel's is not.
Ten subjects with one run each per tool is a sample, not a statistic. I have no visibility into either company's overall numbers and I am not going to pretend my twenty runs are a distribution. Take the ranges as what one person saw in one week.
What that predictability costs: 52 extra credits per model, 18.33×, and the model that arrives still needs its winding flipped.
SupaVoxel's Advanced Options at product defaults: Inference Steps 5, Guidance Scale 5.5, Remove Background on. I opened the panel, changed nothing, and ran it as shipped — every parameter I quote is the default reading off this screen.
Both panels told the truth about what they made
Tripo's completion screen reports Triangle 1954511 / Vertices 1020577, and my offline parse of the downloaded GLB gives exactly that. Tripo did not inflate its own numbers, and that deserves saying. SupaVoxel's panel reports Triangles 997,355 against a parsed 997,355 and Size 0.61 / 1 / 0.76 against a raw bounding box of 0.6088 / 1.0 / 0.7610. Both panels are honest; only one of them costs 55 credits.
Tripo, finished. The readout matches my parse exactly. The View Your Model panel has not moved, so the arm is half covered, and the bottom bar advertises Free Retry (×3) — even the retries are metered.
What the 52 extra credits did not buy
Tripo's premium did not buy bulk, did not buy less support, and bought a triangle edge 1.43× finer that a 0.4 mm nozzle cannot lay down (Tripo 0.58× of the nozzle, SupaVoxel 0.83×). That fineness is real on SLA and worth nothing on FDM.
- Volume at 120 mm — Tripo 250.53 cm³ · SupaVoxel 232.74 cm³
- Resin at $35/L — Tripo $8.77 · SupaVoxel $8.15 · $0.62 apart
- Support area — Tripo 6,761.4 mm² · SupaVoxel 4,858.5 mm² · Tripo +39.2%
- Mean edge — Tripo 0.2326 mm · SupaVoxel 0.3335 mm · Tripo 1.43× finer, unusable at 0.4 mm
Tripo spends the same triangle budget whatever you show it
Across ten subjects generated on the same day with the same settings, Tripo's triangle count ran from 1,896,372 to 1,996,779 — a spread of 5.2%. A candle holder, a watch stand, a tank, this arm: the same number every time. Over the same ten subjects, same day, same settings, SupaVoxel ran from 945,492 to 2,786,054, a spread of 146%; this arm came out at 997,355, and on the tank SupaVoxel shipped 44% more triangles than Tripo in a file 4.1× smaller.
So the accurate claim is not that SupaVoxel is leaner. It is that Tripo's spend does not respond to the subject — a fixed house budget — while SupaVoxel's tracks what you asked for. Ten subjects, same day, same settings is a small sample, and I will say so every time I use it.
The SupaVoxel project list. Every card carries "3 credits · 9/26/2026" — ten test subjects, ten cards, cost auditable one row at a time.
A batch of 100: 5,500 credits against 300
Small workshops do not make one arm. Here is the same job at 100 units, with every assumption stated.
- Credits — Tripo 5,500 · SupaVoxel 300 · 5,200 apart
- Download volume — Tripo 6.29 GB · SupaVoxel 0.56 GB · 5.73 GB saved
- Resin at $35/L — Tripo $877.00 · SupaVoxel $815.00 · $62 saved
- Support area to cut — Tripo 676,140 mm² · SupaVoxel 485,850 mm² · 190,290 mm² less
- Serial wall clock, from my own ranges — Tripo 3.8–5.2 h · SupaVoxel 2.8–24.1 h · the ranges overlap, so nobody gets to claim this row at 100 units
- Post-processing — Tripo: flip winding on 100 files · SupaVoxel: merge shells on 100 files · neither side gets to skip it
Read that wall-clock line carefully, because it is the one place my sample genuinely cannot decide the question. Tripo's best case is slower than SupaVoxel's best case and its worst case is far better — 5.2 hours against a possible 24. If you need a hundred models by a deadline and the credits are somebody else's problem, Tripo's predictability is worth buying. If the credits are your problem, 5,200 of them buy a great deal of patience.
Where the credits actually go: bytes you cannot print
Tripo ships three 4096² textures totalling 6,773,618 bytes, of which 4,154,207 — 61.3% — are metallicRoughness and normal maps a slicer never reads. The normal map alone is 2,676,872 bytes, 4.56× the entire SupaVoxel three-texture set at 586,638 bytes. Nothing in Tripo's export dialog says so: Texture Resolution sits pre-set to 4k (Current), the two dropdowns hold nothing else, and 62.89 MB lands on your disk.
- Texture bytes total — Tripo 6,773,618 B (3 × 4096² JPEG/PNG) · SupaVoxel 586,638 B (3 × 2048² WebP) · 11.55×
- baseColor, the one a slicer might use — Tripo 2,619,411 B · SupaVoxel 345,278 B · 7.59×
- Maps a printer never reads — Tripo 4,154,207 B · SupaVoxel 241,360 B · 17.21×
- GLB on disk — Tripo 62,888,224 B · SupaVoxel 5,627,132 B · 11.18×
The one place SupaVoxel's 3 credits underdeliver
Fair is fair. SupaVoxel's Wire inspection mode is useless at this face count: 997,355 triangles of wireframe render as a near-solid white mass with no readable topology. It should down-sample or warn above a threshold and does neither. It costs nothing here because X-Ray answered the only question that mattered — whether the windows were real openings — in one click. But it is a mode the product ships that does not do its job at the density the product ships.
SupaVoxel's Wire mode on a 997,355-triangle model: a white blob. Recorded as found. The useful inspection modes on this subject were X-Ray and Mesh.
Final verdict: Tripo scores 58/100 on cost
Tripo passed every geometry test on this subject, and Tripo held the tighter timing window — though not the faster one, which was SupaVoxel's on 7 of my 10 subjects. Tripo also asked 55 credits against 3 for a result that ties, withheld the price until after upload, charged the full amount at submit, metered the topology cleanup that would have removed the repair step, and delivered 4,154,207 bytes of texture that never reach a print.
SupaVoxel scores 90/100 on this axis: 3 credits, price visible before upload, five export formats, a batch of 100 for 300 credits and 0.56 GB, and the quicker run on 7 of 10 subjects — against a timing spread of 767 s that you cannot plan a batch around, and an inspection mode that does not scale.
On a clean hard-surface subject like this one, the two products converge on quality. Which is exactly why the price is the decision.
Which one I would use for this job
