Match the screen to the exact model
Use the SL1 dimensions when checking a project or identifying a used printer. Do not order a screen or reuse a machine profile simply because another printer shares the SL1 family name. The official comparison helps distinguish the configurations; a replacement still needs an exact part listing for the installed hardware.
Original Prusa SL1 has the following documented build volume: 120 × 68 × 150 mm. A usable build volume sets the boundary for the object you plan to print. Compare the part in its intended orientation with this envelope before choosing the machine. This measurement is different from the printer’s outside dimensions: fitting the printer on a desk does not establish that a particular part fits inside it.
For Original Prusa SL1, Exposure display size and resolution: 5.5’’, 2560×1440p. Resin wavelength: 405 nm. The exposure display specification describes the imaging system; it should not be presented as an independent test of finished-part accuracy. Keep display resolution, pixel dimensions and layer settings distinct when comparing machines. A useful purchase check is whether the documented resin and slicing workflow matches the parts you intend to make, rather than ranking printers from the screen headline alone.
The resin wavelength is only one compatibility check
The comparison lists 405 nm UV-sensitive resin, 0.025–0.1 mm layer heights, and USB, Wi-Fi and LAN connections. Matching the wavelength alone does not establish an exposure profile for a particular resin. Use the appropriate manufacturer resin and handling documentation; this profile does not provide exposure times or chemical-handling instructions.
Original Prusa SL1 has the following documented listed layer-height range: 0.025–0.1 mm. The same configuration lists exposure display size and resolution as 5.5’’, 2560×1440p. Read the layer-height range as a documented setup parameter, keeping the process and hardware configuration attached to it. It is not a measured dimensional-accuracy result or a guarantee that every model prints successfully at either end of the range. Choose the profile and material instructions for this machine, then assess whether that workflow answers your part’s actual requirements.
Original Prusa SL1 has the following documented file transfer: USB, Wi-Fi and LAN. The same configuration lists build volume as 120 × 68 × 150 mm. Use the named software and transfer route for the actual configuration documented here. Sending a file, preparing a sliced job and controlling the device are different steps; availability of one route does not confirm every other function. Check the manufacturer’s version and interface conditions before moving a workflow from a neighboring model or an older installation.
