Prusa CORE One: closed-door dimensions and chamber limits

Plan around the closed-door qualification

The listed net weight is 22.5 kg. Use that figure and the closed-door dimensions as starting points for placing the machine, then check the installation instructions for access and service space. A cabinet matching only the closed outline has not thereby been verified as a suitable installation.

Prusa CORE One has the following documented depth with door closed: 555 mm. Use the documented dimensions to plan the physical installation, retaining the exact configuration and measurement conditions. Allowing for the stated machine outline is a starting point; confirm access for the documented loading, removal and maintenance tasks before committing to a tightly fitted location.

Prusa CORE One has the following documented weight without packaging: 22.5 kg. Keep this weight tied to the configuration and measurement scope given by the manufacturer. A figure excluding packaging or accessories should not be read as the weight of a delivered bundle. When planning placement or transport, identify which components are actually included rather than borrowing a value from a similarly named version.

Keep the original configuration in view

The documented nozzle is CHT 0.4 mm, with 1.75 mm filament. The chamber statement says “up to” 55 °C; it is not a guarantee of that temperature in every job. Use instructions for the original CORE One and the installed hardware, not specifications copied from a similarly named later configuration.

Prusa CORE One has the following documented installed nozzle: CHT 0.4 mm. Identify the installed nozzle and the exact documented replacement route before changing a print profile or ordering a spare. Diameter, material and printer-family fit are separate parts of that check. A listed option is not necessarily included in the box, and an accessory for another toolhead cannot be declared interchangeable from its appearance or nominal diameter alone.

Prusa CORE One has the following documented filament diameter: 1.75 mm. Match the documented filament diameter when preparing a job; nozzle diameter describes a different component. Keep the spool’s material designation and the selected feed route in view as well. Meeting the diameter entry alone does not resolve restrictions on a material feeder, abrasive material or a configuration that the manufacturer has not named.

Prusa CORE One has the following documented published chamber temperature: Up to 55 °C. Keep the chamber claim separate from nozzle and bed temperatures. An enclosure, an actively heated chamber and an “up to” chamber-temperature statement are not interchangeable descriptions. For the configuration documented here, check the material guidance and any stated conditions; the chamber entry alone is not evidence that every job reaches the listed maximum.
