Product Overview

Original Prusa i3 MK3S+ Specification


There's a direct drive extruder inside.

This direct drive extruder means that the extruder is mounted on the printhead. This then pushes the filament directly into, and out of, the hot end and into your print.

Extruder Type
direct drive

The usable filament diameter is a 1.75 mm diameter.

There are 1 extruders in the printer. Having more than one extruder attached to the printer can help you print material faster, as the printer can focus on multiple elements at once.

You'll get a 210 mm x 210 mm x 250 mm in the Original Prusa i3 MK3S+, so make sure everything you want to print fits in this. You can make do by making your print in pieces, and then assembling, however, sometimes you'll just need a larger build area.

Reviews of the Original Prusa i3 MK3S+

Original Prusa i3 MK3S+
  • - 4.5
As an incremental upgrade in Prusa Research's primary 3D printer line, the Original Prusa i3 MK3S+ offers some modest improvements over the now-discontinued i3 MK3S. Among the changes are an enhanced bed-leveling system, sturdier parts, and improved extruder airflow, all of which serve to make a good printer even better. If you already have the i3 MK3s, you may want to wait until the next generation before replacing it, unless you're anxious to try the five-color add-on.

If you are looking for a top-notch filament printer, then we think is an excellent choice
  • - 3.85
If you are looking for the best of the best when it comes to FFF 3D printers without making the leap to a professional or prosumer model, then we think the Prusa i3 MK3S+ is going to be one of the best options available. It produced some excellent prints and is quite easy to use, along with a great build plate and an impressive range of material compatibility. It doesn't have quite the same build volume as some of the largest printers but is still large enough for the majority of models. We highly recommend the i3 MK3S+ to anyone looking for a top-tier 3D printer.

The Heavyweight Champ Continues to Dominate
  • - 4.4
At a price-point of $999 for an assembled printer (or $749 for a kit), the Prusa MK3S+ is a machine that doesn’t compromise on user experience and is absolutely one of the best 3D printers currently on the market. The MK3S+ has a professional and neat appearance, but the 8-bit monochrome LCD user interface might be a challenge for some users to get past, given the steep price. Interface aside, the prosumer features of the MK3S+ make it a stand-out machine for anyone who is looking for a reliable machine to produce functional parts without worrying about spending a lot of time tinkering.

The Best Gets Better
  • - 4.5
Ultimately though, the Original Prusa i3 MK3S+ remains our go-to desktop 3D printer as the MK3S before it. Operating within the bounds of Prusa Research’s slicer and materials, if you can think it, it’s going to be pretty easy to print it. And even playing outside of the company’s ecosystem of materials and settings, we trust this printer to do it better and with less effort on our part than the others.
