All of the Prusa printers will provide a hassle-free experience for beginners while being an workhorses for hobbyists and professionals. The Prusa Mini is a solid entry-level printer that is perfect for those who want to minimize the amount of tinkering. The Prusa MK3S is the OG printer that is still fantastic for engineering materials and reliability. The Prusa XL introduces a variety of new features but it also carries a hefty price tag of $2,000 to $4,000, depending on the configuration. The Prusa XL pre-orders began on November 18, 2021 with a refundable deposit of $200. They are expected to start shipping between April and August of 2022.

Prusa Mini, MK3S, and XL
- The Prusa Mini, MK3S, and XL all have automatic bed leveling - the Mini and MK3S uses a Pinda, while the XL uses the nozzle and a strain gauge.
- Each has their own magnetic PEI steel sheet.
- All three printers have a filament runout sensor - on the Mini it is an optional feature.
- The printers have a power outage print recovery.
- The printers can be connected locally and networked. Prusa Mini has a USB A, micro USB, and Ethernet port - the Prusa MK3S has a USB B and SD card - the Prusa XL will have an ethernet port and probably a slot for a SD card.
- What filaments can it print at 280°C? PLA, PETG, ABS, ASA, PC (low temps), and even flexibles like TPU.
- The Mini comes with a build volume cube of 180x180x180mm.
- The Mini does not have dual Z-axis beams or motors, and the use of a bowden setup will make printing flexibles slightly trickier + lower reliability/quality around retractions.
- The Prusa Mini is the printer for you if: you are new to 3D printing, on a budget, want to avoid tinkering, are wanting to start a print farm, or are an institution that wishes to implement FDM printers in the classroom or lab.
- What filaments can it print? Anything under 300°C including nylons, flexibles, polycarbonate, and carbon fiber blends.
- The MK3S sports more build volume, 210x250x210mm.
- The MK3S kit comes with a permanent 5% discount on filament, whereas the assembled variant has a 10% discount on filament and future printers.
- The Prusa MK3S is the printer for you if: you have an expanded budget, are wanting to use engineering filaments, or are a business or institution desiring to implement a single FDM printer as a workhorse for prototyping etc.
- What filaments can the Prusa XL print? The temperature will likely be at or above 300°C, so anything that a MK3S can print including nylons, flexibles, polycarbonate, and carbon fiber blends.
- The Prusa XL sports a super-sized build volume of 360x360x360mm.
- First layer calibration (auto-leveling) is completed with the nozzle itself and an embedded strain gauge in the heatsink. No more manual calibrations or leveling!
- Segmented heatbed modules reduce warping and power consumption.
- The Prusa XL can be equipped with up to 5 independent extruders that automatically swap and calibrate during printing.
- The Prusa XL can come with a built-in draft shield or enclosure for printing higher-end materials.
- The Prusa XL is the printer for you if: you have an expanded budget, need a reliable larger printer, want to use multiple materials, are wanting to use engineering filaments, or are a business or institution desiring to implement a single FDM printer as a workhorse for prototyping etc.
