Prusa makes its enclosed CoreXY printer in two sizes: the Core One+ and the larger Core One L+. I use the Core One+ myself, which I built from the kit. The L+ part of this guide is based on Prusa’s specifications.

The short answer
- Core One+ for most people. It is the smaller, cheaper printer and is also sold as a kit.
- Core One L+ if you need big parts, or the actively heated 60 °C chamber for demanding engineering materials.
Side by side
| Core One+ | Core One L+ | |
|---|---|---|
| Build volume | 250 × 220 × 270 mm (14.9 liters) | 300 × 300 × 330 mm (29.7 liters) |
| Chamber | Passively heated to 55 °C, automatic temperature control | Actively heated to 60 °C |
| Max nozzle temperature | 290 °C (up to 400 °C with the HighTemp hotend) | 290 °C (up to 400 °C with the HT hotend) |
| Max bed temperature | 120 °C | 120 °C |
| Printer size | 415 × 444 × 555 mm | 469 × 521 × 635 mm |
| Multi-material | MMU3, INDX version available | INDX version available |
| Price at the time of writing | Kit €1,049, assembled €1,349 | €1,849 |
The real difference: size and chamber
The L+ has about twice the build volume. Its chamber is actively heated to 60 °C, while the Core One+ warms its chamber with the bed up to 55 °C and controls it with an automatic vent. For PLA, PETG, ABS and ASA the Core One+ is plenty. The extra heat of the L+ matters most for large parts in warp-prone materials.
My take
For a home workshop, the Core One+ is the one I would recommend. Most parts fit, it takes less space, and the kit saves money. Go for the L+ if you regularly print parts that don’t fit, or you print a lot of large engineering parts.
