Meshory vs Printventory
Compared with Printventory, Meshory opens OBJ, FBX, GLB, STEP and 3DM, browses ZIP, RAR and 7Z in place, and groups duplicates by geometry.
Printventory is an open-source (MIT) desktop app by the solo developer TechJeeper, built on Electron with a SQLite metadata database. It scans your STL and 3MF files in place, generates thumbnails automatically, finds duplicates by content hash, and offers AI tag suggestions through cloud services. A Docker image adds a server mode with a browser UI for NAS setups.
The two share an in-place scanning philosophy, with content hashing at the core of both duplicate finders (Meshory layers geometry-aware matching on top). The differences that matter are format coverage, performance at library scale, how AI is wired up, and who stands behind it.

The differences that matter.
Formats: two in stable versus eight, plus archives
Printventory’s stable release handles STL and 3MF, with ZIP searching in beta and a 50 MB default per-file cap; its beta channel adds OBJ, STEP, PLY, IGES and F3D previews. Meshory, in its released builds, indexes, fingerprints and views STL, 3MF, OBJ, FBX, GLB, PLY, STEP/STP and Rhino 3DM (saved render meshes), including multi-plate Bambu 3MF projects plate by plate, opens Fusion F3D/F3Z designs and Lychee LYS scenes (experimental), previews DXF, DWG, SVG, xTool and LightBurn files in 2D, and treats ZIP, RAR, 7Z and TAR/TGZ archives as browsable folders.
Scale: both scan big libraries, one stays fast
Printventory's community has scanned 44,000-model libraries, but its own FAQ says a 10,000+ collection can take 1–5 minutes on first load, with lazy loading still listed as future work. Meshory was performance-hardened against a 3.5 TB library holding 118,270 models, archive contents included: it indexes over a NAS in about a minute and a half, plus roughly seven minutes to read inside its 7,500 archives, and thumbnails render in a background worker pool so the library stays usable while a scan runs.
AI: tags only versus descriptions and search
Printventory's AI tagging sends model metadata to Puter, Gemini, OpenAI or Claude, or in its beta to a local model you run, and returns tags. Meshory generates both tags and a searchable description per model, on your own OpenRouter, OpenAI, Anthropic or Google Gemini key, through a local Ollama model that keeps everything on your computer, or through Codex CLI on your ChatGPT plan. Those descriptions are what make semantic search (“steampunk dragon bust”) possible, and it uses an OpenRouter key. Nothing is sent anywhere unless you turn the feature on.
Planning prints: a board per printer, in the release
Meshory's Print queue ships in its released builds: a list for each market or gift run, a board with a lane per printer where you plan each plate (Meshory tells you when a plate is too big for that printer's bed), time and filament added up for what is left, from the slicer or an OrcaSlicer estimate, and a PDF or CSV checklist to print. Marking a print printed or failed builds a Made history on every model, and the library filters to what you have or have never printed. Printventory's stable release has a printed checkbox; its beta adds Want, Queued, Printing, Printed and Failed statuses and a dated print log, with no board that plans prints across your printers.
A hobby project versus a supported product
Printventory is a passion project: open source, community-minded, with an active beta channel. It's also maintained by one person, distributes builds outside GitHub releases, and ships an unsigned macOS app that requires a Gatekeeper override. Meshory ships signed, notarized macOS builds.
Meshory's side of these claims is documented, not asserted: how duplicate detection works, and which formats get thumbnails, a viewer and duplicate matching.
Choose Meshory if…
- You have OBJ or STEP files too, or ZIP, RAR, 7Z and TAR/TGZ archives you'd rather not extract
- Your library is big enough that 1–5 minute load times would hurt daily
- You organize with collections and favorites; Printventory has tags and status fields only
- You want signed, notarized builds on macOS instead of a Gatekeeper override
- You want AI descriptions and semantic search, not only tag suggestions
- You plan prints across several printers and want a board for it in a released build, not a beta
Choose Printventory if…
- You want Spoolman sync, printer maintenance reminders and a parts stock, which its beta channel adds
- You want a Docker server on your NAS with a browser UI on any device
- Your library is STL/3MF-only and modest enough that load times don't sting
Meshory vs Printventory: common questions
What does Meshory add over Printventory?
Reach and scale: OBJ, FBX, GLB, STEP and Rhino 3DM as well as STL and 3MF; ZIP, RAR, 7Z and TAR/TGZ browsed in place; geometry-aware duplicate grouping; collections and favorites; a Print queue that plans each plate on a board per printer; AI descriptions with semantic search; signed, notarized macOS builds; and a scan tuned against a 118,270-model library. Meshory is a $34.99 one-time license with no subscription.
Which formats does each app support?
Printventory's stable release handles STL and 3MF, with ZIP search in beta; its beta channel adds OBJ, STEP, PLY, IGES and F3D (as of September 2026). Meshory indexes STL, 3MF, OBJ, STEP, FBX, GLB, PLY and Rhino 3DM (saved render meshes), opens Fusion F3D/F3Z designs and Lychee LYS scenes (experimental), previews DXF, DWG, SVG, xTool and LightBurn files in 2D, and browses inside ZIP, RAR, 7Z and TAR/TGZ archives without extracting them.
Do both find duplicate files?
Yes, both use content hashing, so renamed copies group together. Printventory shows duplicates in a DeDup view with thumbnail comparison. Meshory goes further: exact matching reaches inside archives and across NAS sources, a geometry tier groups the same mesh saved as different files, and moved, rotated or rescaled near-copies land in a separate review queue. Nothing is ever deleted for you.
Which is better for a NAS?
Different approaches: Printventory offers a Docker server mode you run on the NAS and reach by browser (its FAQ marks network paths experimental). Meshory is a desktop app that indexes NAS mounts alongside local folders: network sources are browsable right away, and duplicate analysis is a separate pass you start when it suits you, paced in short batches so the drive stays responsive.
