The file Elegoo's newer resin printers print from, a picture of the screen for every layer. Open one right here and see the print before it cures. Nothing leaves your device.

What you'll see
Your print opens in 3D, rebuilt from its layers, with a bar under it to build it up layer by layer and the slicer's picture and settings beside it.
- The layer bar • Build it up, the cut at each layer lit
- Inspect • The layer as the screen lights it, and its exposure
- Its size, layers, resin and print time
- Export • Layers as PNG or ZIP, STL and PNG
About GOO
Elegoo made GOO for its Mars and Saturn resin printers and published how it's laid out, so any slicer can write one. Chitubox and Elegoo's own slicers save it, each layer a picture of what the printer's screen lights, its grays in runs, with its own exposure, lift and wait, after a header of the job's settings and the slicer's two pictures of the print.
The printer reads the file from its USB stick, and nothing built into Windows, macOS or phones opens one. Chitubox and UVtools show one on a computer, and the printer's own screen shows the slicer's picture.
Filepeek reads the layers in your browser and rebuilds the print in 3D from them. Drag the bar under it to build it up layer by layer, the cut at that layer lit, and Inspect shows the layer as the screen lights it, with its exposure, and the job's resin, print time, layer height and printer. Export saves the layer as PNG, every layer as a ZIP, the print as STL and the slicer's picture.

Questions
Can I check a print before it goes to the printer?
Yes. Drag the bar under the print to build it up layer by layer and see what each layer cures, with its exposure in Inspect, so a part that starts in midair or a missing support shows before you print.
Why are the edges of a layer gray?
That's the slicer's anti-aliasing: pixels on an edge get a gray so the screen cures them less, which smooths the steps between layers. Inspect shows the layer as the screen lights it, grays and all.
Can I get the model back as an STL?
Yes. Export's Save as STL writes the print rebuilt from its layers, as fine as the screen's pixels and the layer height. It holds the supports too, so the model you sliced is the better start for changes.
Can my printer print a CTB instead?
Only the format its maker chose. Slice the model again in Chitubox for your printer, or convert the file in UVtools.
