Prusa Research

Prusa CORE One+

Prusa's enclosed CoreXY printer. Open-source firmware, sold as a kit or assembled, built to be repaired for years.

Strengths

Open firmware and published parts, so you can fix it yourself
Building the kit teaches you how a printer works
Long upgrade path. Prusa supports machines for years

Trade-offs

Costs more than Bambu for similar print quality
Multi-material setups are less plug-and-play

Prusa is the open-hardware choice. The CORE One+ is an enclosed CoreXY machine, and unlike most of its competitors the firmware is open source and the printed parts are published. If something breaks in five years, you can still fix it.

You can buy it as a kit, which costs less and teaches you every bolt in the machine, or factory-assembled. Prices differ by option and region, so follow the link for today’s figure.

Who it’s for: people who see the printer as a tool to own and maintain, not an appliance. If you just want prints with the least effort, the Bambu P2S is cheaper.
