If you sell the prints you make, this is the licence you need. You still need the rights to the picture: your own work, a public-domain source you have checked, or permission from whoever owns it.
If you also sell the files Polychrome makes, for your customers to print themselves, you need Creator.
Both licences activate on up to three computers and renew each year, and you can cancel any time. If one lapses, the prints you made while it was active are still yours to sell. What stops is building new plates until you renew.
This is what the slicer reports for the 200 x 200 mm macaw plate I printed, and for the same plate at 150 x 150 mm with the same five rolls, both on an X1C at 0.08 mm layers.
| 200 x 200 mm | 150 x 150 mm | 150 mm, P1S (slicer estimate) | |
|---|---|---|---|
| Print time | About 14 and a half hours | About 10 hours | About 9 hours |
| Filament | About 63 g | About 43 g | About 43 g |
| Purge | A few grams, under 3 g | About 4 g, with a prime tower | About 4 g, with a prime tower |
| Filament changes | 31 | 31 | 31 |
| Pauses | One, to swap black for white | One, to swap black for white | One, to swap black for white |
The purge figure is the slicer's own estimate for that project, and the app sets the flush for the project it exports. The 150 mm plate purges more because that project has a prime tower and the 200 mm one did not.
The P1S column is the slicer's estimate for the same 150 mm project, not a print I have made, since I only own an X1C.
Personal is a one-time purchase. Commercial Prints and Creator renew each year.
