Prusa Core One vs Core One L vs XL: Which Large-Format Prusa?

Once you've decided you want a larger Prusa, three machines are in play: the Core One Plus +, the Core One L, and the XL. They share Prusa's CoreXY thinking but differ sharply in build volume, chamber capability, and — in the XL's case — the ability to run multiple toolheads. Here's how to choose the right one for the size and type of work you do.

Head to Head

Core One Plus +: The All-Rounder

The Core One Plus + is the baseline enclosed CoreXY — 250×220×270 mm, active chamber to 55 °C, compact footprint. For the majority of enclosed-printing needs (ABS, ASA, PC, nylon at typical part sizes), it's the right machine and the best value of the three. Choose a larger model only if you specifically need the volume.

Core One L: Double the Volume, Same Footprint Philosophy

The Core One L roughly doubles the build volume to 300×300×330 mm (~30 litres) while increasing the footprint by only about 10% over the Core One. It adds an AC convection cast-aluminium heatbed with very even heat distribution and an actively heated chamber up to 60 °C. This is the machine for large engineering parts printed in one piece — enclosures, jigs, fixtures, and sizeable functional components in ABS, ASA, or PC that need a reliably heated chamber across the whole build.

XL: Multi-Toolhead and the Largest Volume

The Original Prusa XL is a different proposition. It offers the largest build volume (360×360×360 mm) and, uniquely, up to five independent toolheads — enabling true multi-material and multi-colour printing without purge waste, since each toolhead carries its own filament and the printer swaps them automatically. Its segmented heatbed heats only the tiles in use, saving energy on smaller prints. The key distinction: the XL's enclosure is passive, not actively heated. It's superb for large multi-material prototyping and production, but for high-temperature engineering polymers that demand a hot chamber, the Core One L (or the Pro HT90) is the better tool.

Which Should You Buy?

• Core One Plus + — most enclosed-printing needs at typical part sizes; the best value and footprint.
• Core One L — you need large parts in one piece with a reliably heated chamber for ABS/ASA/PC.
• XL — you need multi-material/multi-colour via multiple toolheads, or the largest single build volume, and a passive enclosure is sufficient for your materials.

Working with high-temperature polymers like PEEK or PEI? None of these is the dedicated tool — see our Pro HT90 guide. For the whole range, see the complete Prusa buyer's guide.
