Use Cases

Hobby makers — mesh sanity before the first layer

You just finished a mesh in Blender / Tinkercad / downloaded from Thingiverse. Before you burn 8 hours of print time, check it.

What you get

• ✓
  Drop STL in browser — 11 topology checks run client-side in under a second. No upload, no account, no tracking.
• ✓
  Is it closed, any holes at the edges, any empty faces, any overlapping pieces — the issues that cause silent slicer fixes and weird first layers.
• ✓
  Every check tells you exactly what was found, in plain language — no number you have to interpret.

AI 3D output — catch and fix messy topology before you print

Meshy, Kaedim, Luma, Shap-E, TripoSR — text-to-3D and image-to-3D output is beautiful to look at, but the triangle topology is often unprintable. AdMeshio was built with this in mind: detect the defects, then fix them.

Typical AI-mesh issues we catch

• ×
  Overlapping surfaces — slicers patch them over silently, leaving voids inside the printed part
• ×
  Non-manifold edges — edges shared by 3+ faces, impossible in physical material; confuse slicer ray-parity
• ×
  Inverted normals — flipped face winding that looks fine in preview but slices as negative volume
• ×
  Over-tessellated regions — millions of near-zero-area triangles that slow slicers to a crawl

Then fix them

admeshio repair closes the cracks and overlaps, flips the wrong-way faces, and recognises intentional openings (drains, peg sockets) so they don't get sealed by accident. Chain decimate after if the AI output is too heavy for your slicer.

Tested across AI-generated mesh exports — see the validation page for check coverage.

CAD STL exports — catch boolean-op leaks

Fusion 360, SolidWorks, Onshape, FreeCAD export to STL. Boolean operations (union / difference / intersect) on complex assemblies can leave tiny holes or overlapping regions that the exporter doesn't clean up. Visually identical to a clean export — behaviorally broken in the slicer.

Common patterns we catch

• ×
  Tiny holes where surfaces nearly overlap after boolean operations
• ×
  Self-intersections at fillet boundaries after chain-edits
• ×
  Stray disconnected shells (component merge artefacts)
• ✓
  Clean diagnosis in seconds rather than 10-minute Meshmixer session

Pre-print preview — mesh + your slicer output in one audit

You already have a G-code (FDM) or CTB (resin) from your slicer. AdMeshio audits the mesh and verifies your slicer output in a single pass — not a simulated one, the actual file your printer will run.

What you get back

• ✓
  Upload mesh + slicer output. admeshio audit mesh.stl --recipe bambu_x1c_pla_standard --external-gcode my.gcode for FDM; admeshio audit mesh.stl --recipe elegoo_saturn3_std_resin_standard --external-gcode my.ctb for resin.
• ✓
  One combined report: mesh topology (GRI-G) + profile fit (GRI-R) + slicer-output checks (GRI-I). All three from your actual files.
• ✓
  FDM (17 checks): temperature out of range, feedrate over printer limit, volumetric flow over hotend capability, cooling layer time too short, first-layer speed on textured PEI, nozzle collisions, absurd acceleration, zero retraction before travel.
• ✓
  Resin (11 checks): bottom-layer adhesion, exposure window vs material, floating islands, peel-force spikes, 3D-confirmed vacuum traps (drains hollow + drain shells), printer-profile mismatch, lift-cycle divergence.

Works with

FDM: OrcaSlicer · Bambu Studio · PrusaSlicer · SuperSlicer · Cura · Simplify3D
Resin: CHITUBOX · Lychee · Voxeldance · Anycubic Photon Workshop

Functional parts — spot weak spots in the geometry early

Brackets, fixtures, mounts, jigs — anything you'd rather not see crack the first time you load it. admeshio stress-check runs a structural FEM pass on the part by itself and returns a first-pass safety factor plus the regions where stress concentrates. Use it as an early sanity check before committing to a long print.

What you get back

• ✓
  Default scenario: gravity + cooling shrinkage with the bottom fixed. No load points to configure.
• ✓
  Custom load for a closer-to-reality probe — pick where to fix, where to load, how much. Pass --fixed-z, --load-axial, --load-region.
• ✓
  Cross-checks structural walls against stress hotspots — thin features that would pass an audit on their own but become weak points under load.
• ✓
  Six material presets: PLA, ABS, PETG, resin, nylon, PA12.

Scope: stress-check models a single part with simplified loads — surfaces obvious weak points fast, before you commit a print. For multi-part assemblies or load-critical work, pair the result with a dedicated FEA review for a complete picture.

Marketplace pre-listing — prove your mesh is clean

Sell models on Thingiverse / Printables / Cults3D / MyMiniFactory / MakerWorld? Customers burn filament on broken meshes and review bomb the listing. Run AdMeshio before you publish — catch the issues the seller should have.

Workflow

• ✓
  Drop the STL you're about to list. AdMeshio returns a topology report in seconds.
• ✓
  Download the HTML report — attach it to the listing, embed the summary in the description.
• ✓
  Batch folder: checking 20 variant STLs of the same model takes a single command.
