The Prusa XL+ replaces the Original XL. Here's what changed
Same frame, same build volume, same toolchanger. New offset sensor, belts, cooling, wiper and nozzles, plus an upgrade kit for existing XLs, with one catch on older toolhead boards.
We haven't tested this yet
On 13 August 2026 Prusa replaced the Original Prusa XL with the XL+. The old product URLs now show the new machine. Prusa says the build volume (360 × 360 × 360 mm), the toolchanger design and material support “carry over unchanged”, and that G-code sliced for the XL runs on the XL+ as-is.
What’s different
- Tool offset calibration. The XL used a removable pin and a guided routine. The XL+ has a permanently mounted eddy-current sensor that Prusa says is “about 20 times faster”.
- GT1.5 belts, which Prusa says make fine repeating patterns less visible on large smooth surfaces.
- 360° part cooling with new print fans, plus extra fans for the mainboard and bed electronics.
- A nozzle wiper, replacing the old nozzle-cleaning procedure.
- High-flow (CHT) nozzles as standard.
- 30+ printed parts in PC and PCCF, for higher enclosure temperatures.
- A new enclosure that Prusa says reaches about 50 °C passively, or 60 °C with an external heater that doesn’t have a ship date yet.
- Speed: Prusa claims “10-15% faster than the Original Prusa XL”. It hasn’t published how that was measured.
Prusa says prices stayed the same.
If you own an Original XL
Prusa sells an XL → XL+ upgrade kit. On the US store on 6 October 2026, it ranged from $249.99 (single tool, no nozzles) to $589 (five tools, with nozzles), with a 7–8 week lead time. It includes the belts, fans, wiper, printed parts and fan shroud. The tool offset sensor comes only with the two- and five-tool kits, since a single-tool machine has no offsets to calibrate.
Check your toolhead boards first. The kit page says: “If your Dwarf board is marked with a number 07 or lower, it is necessary to replace it with a new one before upgrading.” Check every toolhead.
The kit doesn’t upgrade the enclosure. The original XL enclosure still fits, but Prusa says it “won’t reach 50°C like the new one”.
Prusa says existing XLs “will continue receiving firmware updates, PrusaSlicer improvements, print profiles, documentation, spare parts, and support”. The 6.10 firmware is a single build for both machines.
What we’re doing
Our five-head XL is an Original XL. We’re testing it as it is first, so the results describe the machine most current owners have. If we fit the upgrade kit later, that becomes a separate, clearly labeled configuration with its own before-and-after runs.
