Preview 3MF files on your Mac, plate by plate.
HEXOstudios renders your 3MF print projects as thumbnails, shows how many plates each one holds, and lets you step through every plate in 3D, without opening a slicer.
- MULTI-PLATE 3MF
- 12 FREE 3MF PREVIEWS
- UNLIMITED 3MF WITH PRO



3MF projects you recognize at a glance.
A 3MF file is more than a mesh: it can carry several plates, many objects and the settings they were prepared with. In Finder it’s just another filename. In HEXOstudios it’s a rendered card you can recognize, search and organize alongside the rest of your library.
Thumbnails for your 3MF files
HEXOstudios renders each 3MF project as a thumbnail in your library, in the file’s own colours, painted colours included, right on your Mac.
The plate count, on the card
Multi-plate 3MF files are recognized automatically, and the number of plates is shown right on the file card, so you know what a project holds before you open it.
No slicer needed to look
Checking a 3MF normally means launching a slicer and waiting for the project to load. HEXOstudios is a viewer and library, not a slicer: open the preview, look, move on.

Step through every plate in 3D.
Plate by plate
When a 3MF holds more than one plate, the 3D preview shows a plate navigator. Step forward and back through each plate and see exactly what’s on it.
Full 3D Preview PRO
Open the project full-screen with orbit and zoom, and keep stepping through its plates there too.
Plate names and object counts PRO
File Passport lists each plate’s name and how many objects it holds, so a large project stays readable.
File Passport: the print details inside a 3MF.
File Passport, part of HEXOstudios Pro, is a detail sheet for 3MF, STEP and G-code files. For a 3MF it reads what the file carries, when the file includes it:
Print setup and filaments
- Author, app and title
- Plate names and object counts
- Dimensions
- Printer, nozzle and layer height
- Filament colours, types and amounts
- Print-time details
Your own notes and tags
Add notes and tags to any file, so the settings that worked, or the print that failed, stay with the model in your library.
