Looking for the best RepRap Prusa i3 kit? Read our buyer’s guide to 33 Prusa i3 kits on the market today, including a Prusa i3 MK2 review.
Did you know that the RepRap Prusa i3 is the most popular 3D printer in the world? It’s more widely used than machines made by Ultimaker, Makerbot, or Zortrax.
At least, this is the picture according to the latest 3D Hubs trend report, where this RepRap 3D printer accounts for 8.3% of 3D printer model distribution globally. On a regional basis, it’s the top 3D printer in North America (6.5%), Europe (9.8%), Asia Pacific (6.6%) and South America (11.9%).
How is this possible? Two words: “open” and “source”.
Developed for the RepRap project by Josef Prusa, the i3 — short for iteration 3 — is a fully open source 3D printer. The design of this FFF (fused filament fabrication) 3D printer is versatile and reliable and many of its components are cost-effective and upgradeable.
As a result, a veritable explosion of budget Prusa i3 clones is available to buy. We’ve listed the best RepRap Prusa i3 kits under $1,000, together with pricing and details on where they can be bought. The majority of them can be purchased for less than $500.
Important Note: These RepRap Prusa i3 Kits are ranked according to price — with the exception of the Original Prusa i3 MK2, which sits at the top — and their position in the list is not indicative of their quality.

This Reprap Prusa i3 kit is a very basic model with decent specifications and quite a few upgrade options. Starting at $149 USD, it is easily the cheapest Prusa i3 kit on the market today. It has a maximum resolution of 50 microns, an LCD screen and a build volume of 200 x 200 x 200 mm. And thanks to its heated bed, it’s possible to print with different materials like ABS.
It is possible to order this RepRap Prusa i3 kit with a larger build volume at 200 x 280 x 200 mm, an auto-levelling system, and the single E3D full metal extruder. All upgrades, however, add to the price of the printer.

The FLSUN is a sturdy machine with an aluminum frame. Last updated in June 2016, there are now two cooling fans to cool the extruder and filament. The build volume of this Reprap 3D printer is 200 x 200 x 200 mm, and features a maximum resolution of 100 microns and a heated print bed. Available upgrades include an LCD control panel and an SD card reader.

With a simple and sturdy construction, the TEVO Tarantula is a Reprap Prusa i3 kit that’s easy to assemble with good performance and quality. Optional extras include automatic bed leveling and bigger build volume. The auto-leveling version uses a proximity sensor to detect the aluminum print bed, whereas the normal version of the printer uses a micro-switch to detect the end of travel for the Z-Axis movement.

The Replikeo is available in either an aluminum, steel or acrylic frame, as well as with the option to choose between 1.75 or 3.00 mm filament diameter compatibility. Apart from that, standard features include a 200 x 200 x 180 mm build platform, a maximum print resolution of 100 microns, and a heated print bed.
The one drawback of this RepRap Prusa i3 kit is the lack of an SD card slot. The only way to connect to the machine is via a USB cable, which limits the location of your printer to somewhere near your computer (unless you’re using a laptop).

The GearBest A8 is held together with a piano-black acrylic frame. All rods, gears, bearings and connectors are made out of stainless steel. This is important for the stability of the machine to ensure smooth operation. The print volume of 220 x 220 x 240 mm is rather generous and unconventional for an i3 rework. Other features include a heated print bed and an LCD screen interface.

The I3 X is a new addition to Geeetech’s line of Reprap Prusa i3 kits. With a low-cost design, while still emphasizing usability and quality, this printer has a laser-cut, piano-black acrylic frame for a “just built in the garage” feel. Features include a build volume of 200 x 200 x 170 mm, a maximum print resolution of 100 microns, an LCD screen, a heated print bed, and connectivity via USB and SD card.

Folger Technologies has an elegant but affordable variation of the Reprap Prusa i3, with a frame constructed from laser cut acrylic plastic. It comes with mostly everything you need to build your own machine, with the exception of an 8″x 8″ glass surface for the print-bed. An LCD screen with an SD card reader is also available as an optional extra. The same company offers another kit with an aluminum frame that’s not so pleasing to the eye (but it is easier on the wallet).

This Prusa i3 kit is actually a RepRap hybrid, combining an i3 frame and the mechanics of a dual Ormerod 2 extruder. The Ormerod 2 bowden extruder is a simple, fast and steady extruder, using 1.75mm filament and maximum accuracy is 100 microns. The machine also has an inductive auto-leveling sensor, which does away with the need for manual calibration.
The plastic parts holding the frame and axis are all ABS injection molded, so they shouldn’t weaken over time. Altogether a very tidy package of features, and for less than $300 it’s incredibly good value — but the lack of an LCD interface may deter newbies.

RepRap Guru are offering a complete Prusa i3 kit that doesn’t require altering, drilling, soldering or cutting. Included with this complete kit is a square plate of borosilicate heat bed glass (something that’s missing from the Folger Tech i3 kit, for example); fully soldered MK2B heat bed with all the necessary wires; fitted connectors to all wires; and longer motor wires for better wire paths. With these carefully considered upgrades, you should be able to eke out some better quality prints.

The Sintron features an acrylic frame, which blends nicely with the steel rods to create a simply constructed, nice looking piece of machinery. The print area of 200 x 200 x 180 mm is typical for i3 printers. An LCD 2004 controller is the interface by default, which includes an SD card slot for easy offline access. Other features include a heated print bed and a maximum print resolution of 100 microns

The Monoprice Maker Select is actually a rebadged Wanhao Duplicator i3, and word of mouth from users is that it’s painless to use and the results are reliable. A unique design feature of the Maker Select; the power brick and control panel are housed separately to the main body of the printer. Other topline features are the sturdy metal frame, heated bed, and standard build volume of 200 x 200 x 180 mm.

The HICTOP MK8 has an interesting tweak to the original design. It features an alarm to notify you when filament is running low, so you’ll never be left hanging in the middle of a print job. If this is a recurring problem for you (and you find it difficult to judge just by glancing at the spool) then HICTOP MK8 has the solution. One other respect that makes it special is the huuuuuuge build volume of 269 x 210 x 195 mm, the second biggest on this list.

The Geeetech i3 Pro C is another dual extrusion Reprap Prusa i3 kit on our list, and it offers a bit more polish. Most obviously, it has the onboard control panel as standard, where users can manage print jobs and general settings like build platform calibration. It also displays the temperature of the extruder heads and the build platform, as well as the progress of a print job. What the GeeeTech is lacking is an auto-bed leveling feature, which would have been nice to have; perhaps something to explore as the next DIY project in your 3D printing odyssey?

Laser cut from sheets of aluminum, the Psique is an imposing machine. It looks like a 3D printer from the era of steampunk. The benefit of using aluminum over, say, steel is that it has all the strength whilst being significantly lighter. Also, it won’t rust if you leave it out in the rain. But then again, why would you do that to your poor 3D printer?

The M201 by WER has the biggest build volume of all RepRap Prusa i3 kits on this list; a whopping 280 x 210 x 200 mm. It doesn’t have a fancy pants feature like auto-bed leveling or dual extrusion, but it does offer *one* unique feature you won’t find anywhere else (at this price); a hotend that accepts filament from two extruders. This is rather unusual, but the idea is that you can blend filaments to offer a variety of color palettes and gradients in your printing. The process is managed via WER’s own proprietary firmware. Tempted to make some tie-die prints? Now’s your chance.

The ION has been designed entirely by ThingiBOX, and has undergone a process of continuous improvement since 2012. This RepRap Prusa i3 kit includes everything for the construction including screws, electronics, cables, connectors, heatshrink tubes, kapton tape, cable binders, USB cable, clips, and more. The frame, the base, and almost all the components are developed and manufactured in white and transparent methacrylate, making the design elegant yet robust.

The JGAURORA has nearly all metal parts, which makes for a nice and sturdy quality design. The build volume of this RepRap 3D printer is 200 x 200 x 180 mm and it features a heated print bed (so printing with ABS material is also possible). A maximum print resolution of 100 microns is pretty standard. The LCD screen interface allows the printer to be operated using an SD card only, without the need for a computer in close proximity.

The word “Mejorada” is Spanish for “Improved”. This RepRap Prusa i3 kit includes a powder coated steel frame, an LCD screen, and can be configured at purchase from 8 different hotends (including the ever-popular E3D v6). It also has a heated bed, and a build volume of 210 x 210 x 210 mm. Pretty much everything you need to build your first desktop 3D printer.

The name of this RepRap 3D printer is misleading; there’s no such thing as a Prusa i4. Or, at least, Josef Prusa hasn’t gotten round to designing one. Sunhokey are guilty of being overexcitable in trying to distinguish their Reprap Prusa i3 clone from the rest of the pack. Which is a pity, because the machine itself looks like a neat refinement, with a heavy metal base and a unique X-axis rotation design with the motor mounted to the extruder housing.

The MakerFarm i3v series comes in 8″, 10″ or 12″ sizes. Either dimension is one side of the square printing space, converting into lengths of 203 mm, 254 mm or 304 mm. Customers also get to choose from a wide range of nozzle sizes, as well as the heat bed mount material (aluminum, wood) and the extruder. The type of material that can be printed with this 3D printer depends on the nozzle that is selected.
Other features include a maximum print resolution of 50 microns and an LCD interface for complete offline use.
The Wanhao Duplicator i3 Plus is a major enhancement of their popular Wanhao Duplicator i3 (which has recently been rebranded as the Monoprice Maker Select). Topline features on this Reprap Prusa i3 kit is a powder coated steel frame, build volume of 200 x 200 x 180 mm, an integrated electronics cabinet (whereas before it was housed in a separate brick), a full-sized SD card slot, and a touchscreen control interface.

The Ooznest has a comical name, but otherwise, should be the perfect printer for beginners or pros alike. Each part has been carefully considered in terms of assembly, maintenance, and printing, with upgraded components like the Hexagon all metal hotend and the Bulldog Lite direct drive extruder. In a recent review of the Ooznest by Tech Radar: “Building the kit-based Prusa i3 could be challenging depending on your ability, but the end result is a 3D printer with a print quality that easily matches many other FDM printers at twice the price.”

The Steel Pro is another metal-clad remix. It has a stronger frame laser cut from galvanized steel and is simple to assemble. However, though more compact and easier to transport that the i3 that inspired it, it’s significantly heavier. What else? Oh, this Reprap Prusa i3 kit tends to rank high on the 3D Hubs monthly trend report, sitting pretty in the top 20 for the past three months.

The helloBEEprusa is designed with the education sector in mind. It comes with a quick-start manual, all the components are in numbered and labeled boxes, and there’s a series of videos to guide you through the assembly process. This RepRap Prusa i3 kit has a generous build volume of 185 x 200 x 190 mm, plus a dual extruder (ideal for printing with a soluble filament as support for more complex parts), and a heated bed for a better adhesion of print jobs.

The Rework 1.5 is a remix of the base i3 design by RepRap France. This RepRap Prusa i3 kit has a 6 mm thick aluminum frame and a Y carriage for a platform within 200 mm stops. The Hexagon hotend is a fully machined metal nozzle that can accommodate several diameters from 0.3mm to 0.5mm. The RAMPS 1.4 controller can support up to two nozzles and is capable of layer resolutions up to 100 microns.

All the 3D printed parts on the Achatz Edition were fabricated in ABS plastic at low speeds on ReprapUniverse machines, guaranteeing the highest possible quality of parts. And if a part breaks during the assembly of the printer, they’re happy to send you a free replacement. They have also made some improvements to the base design, like Aluminium Z Motor Couplers, a Trespa Y Carriage Plate, and enhanced frame rigidity using High-Quality Trespa (HPL). Optional extras not included in the base kit are an LCD screen for SD card connectivity and a fan upgrade for the extruder.

The Aus3D Mark2 has been designed to be sturdier than the average i3 based 3D printer. Threaded rod and printed fasteners have been replaced with extra-thick 10 mm acrylic, and the frame has been designed to reduce vibrations. The threaded-rod Z-axis has been replaced with an improved lead screw driven system, reducing Z backlash and allowing for smoother Z motion. The rigid frame ensures all axes are held square, ensuring optimal print quality.

The Hephestos 2 is the new and improved version of the predecessor model from BQ, the Hephestos 1. It’s very clearly based around the i3 open frame design, but with a carefully considered approach to assembly and features, including an auto-leveling sensor probe and a powerful hot-end that’s perfect for printing with flexible filaments. There’s no heated bed, however, so high-temperature filaments like ABS and Nylon are not an option. Most impressively, BQ claims this RepRap Prusa i3 kit can be assembled in less than an hour.

The i3 Berlin is a high-end derivative aimed at refining the improving the base design, by stiffening the frame and hiding away the circuitry. You can also add dual extruders as an optional extra. You’ll often see these machines in Fab Labs all over Germany, and if you live in the Berlin area, you can also buy a kit and attend a workshop to build and assemble your very own 3D printer.
