Product Description

The Prusa i3 is a RepRap model designed by Josef Prusa. Compared to its predecessors and other RepRap machines, Prusa i3 is known for its extreme ease of assembling, reliable printing, and dual extruder option. This kit uses laser-cut acrylic sheets to improve stability. In our experience, the Prusa i3 can be assembled within 3 hours, making it ideal for first-time RepRappers.

Just to make the deal sweeter, at $499, our Prusa i3 ships worldwide for free! We ship through DHL express to North America and Europe, with Hong Kong Post to Asia and Oceania.

This Prusa i3 kit includes everything for you to build the Prusa i3 except for local power-cable (“kettle”-type plug as used with computers) .

Q & A for Czar’s Prusa i3

    Q: What other parts do I need to buy to get the Prusa i3 functioning?

A: This kit includes everything needed except for the power cord. This is the cable you use for everyday electronics from computer monitors to microwave. We do not include the power cord because we ship worldwide and different regions have different types of plugs. Also, to improve ABS print quality, a roll of Kapton tape is also recommended.

    Q: Safe is your packaging for this Prusa i3?

A: We use customized EPE foam and 5mm thick cardboard boxes to protect your printer. This is why we dare to include the 3mm borosilicate glass in our kit, and never had a problem with it.

    Q: How fast is your shipping for this Prusa i3?

A: Shipping to Europe and North America are done through DHL express free of charge (yes, it’s true!). Our customers receive the Prusa i3 typically within 4 days after shipping. We are working with DHL to help extend this service to the rest of the world, but right now we use Hong Kong Post to deliver Prusa i3 to Oceania, Asia, and South America (free of charge, of course!). The shipping is also speedy and fast, usually delivered within a week in Asia and two weeks in Oceania. One can also choose the SpeedPost service from Hong Kong Post if he/she wishes to get the Prusa i3 faster. We are very proud of our service and below are some snapshots of our past shipping.

    Q: What if some parts of my Prusa i3 are broken upon arrival?

A: We carefully inspect all the parts before packaging the Prusa i3 to minimize this from happening, but if that did happen, free replacement at free shipping, no question about it.

    The good, the bad, and the ugly:

    The good: It arrived in a timely manner. The printed parts look well made. Although I haven’t gotten to the electronics yet, they appear to be in good condition. It is really nice to finally have the metric tape measure I have always wanted.

    The bad: The rods smell like they were soaked in gasoline which is just wonderful in a small apartment in winter. There are no instructions at all.

    The ugly: The lack of instructions wouldn’t be much of a problem since there are quite a few assembly examples on the web, except that none of the examples I found have the parts in this kit. Several parts appear to be missing. The z-couplers, belt guides, many washers, torpedo level and possibly more are all missing in action. The supplied wrench doesn’t fit any of the nuts.

    I went with this kit because of the 3 $500 kits I found, it was the only one I didn’t see complaints about. That really shouldn’t have been a consideration. I can’t say I feel totally ripped off because there are a lot of valuable (and untested) parts, the problems are just annoyances which I can probably correct without a lot of cost. However, I got the kit precisely because I wanted to avoid shopping around in 10 billion different places for odds and ends.

    :

    There were some goods, bads, and uglies associated with this kit (as the above review mentions).

    First, the ugly, NO INSTRUCTIONS! (an update: a detailed hardware build instruction as well as the STLs have been provided. Please see RepRap wiki or the link provided on the Prusa i3′s page) I know that this is being worked on but kits should not be shipped without instructions unless there is a clear understanding by the buyer that this is the case. Even then there would be some things that would have helped mitigate frustration. First, provide some high quality photos of an assembled printer taken from multiple angles! Second, provide some links to the most relevant variants of this particular printer where instructions do exist!

    Next, the bad. As Greg stated in his review there were some missing parts in my kit and the wrench that was provided was one size too small to actually fit anything! In my case at least some of the missing parts might be due to a customs inspection as the printed parts bag was open and parts had spilled from it.

    Finally, the good. This kit really does provide excellent quality parts for what I think is the best variant of all the Prusa printers and at a very reasonable price. I could not find a better price for the Prusa I3 with Ramps (though I did find a comparable price with a Sanguinololu board. I had also priced out the sourcing of parts on my own and the end price would have been pretty close to the cost of this kit. I would also say that the support of my build from Han in Hong Kong was pretty good considering that he is probably pretty stressed out by having to answer questions that documentation would circumvent!

    The bottom line…once documentation is available for this kit buying one is a no brainer. Good quality parts, a great variant of the Prusa I3, and literally everything you need in one nicely packed box (save a region specific power cord and some missing parts which I know the Czar can sort). The kit even comes with the glass for the heated bed which many kits do not. Even without the documentation, and you are prepared for a challenge, I think it is a good deal.

    More on my build of this kit can be found on my blog at

    Some issues:
    * missing parts (got replacements)
    – z axis links, can be replaced with 1/4″ (1.71ID) clear tubing
    – MANY screws and hardware in general. Hard to find long small screws, and M3 in particular, locally
    * hard to find instructions specific to the details of the kit, but that starts to come together and become more obvious as you progress. Start with your choice of generic i3 instructions and work your way to specific head instructions.

    Firmware must also be chosen, configured, and pushed to the Arduino.

    This is not a plug and play object for consumers, and was nowhere near a 3 hour build time.

    :

    I’ll do a pro and con review since I dont think there’s anything “ugly” about this kit:

    cons: I see a lot of reviewers talking about the missing instructions, but I found the hardware instruction quite thorough on the Prusa i3′s page. I didn’t find an electrical on on the website but since it’s generic RAMPS 1.4, I used one from makerfarm and worked great. I’ve learnt a lot about RAMPS now and am experimenting with some new features like LCD controller and more endstoppers. The motors do not have connectors attached, and I spent like an hour just trying to crimping the pins (connectors and pins provided). This really made my hands numb (20 pins in total) and boring I just hope I dont have to do it again in the future. The acrylic frame looks nice, but the bed bends a bit as the heatbed spring puts pressure on it. I haven’t seen any issues in my print but will loosen the pressure to prevent anything bad from occurring. Maybe 6mm plywood is better?

    Good: No missing parts and extremely well packaged. They used 2cm customized foams to protect the kit and I felt that I could literally drop the box and nothing would break. Very fast shipping to Australia: the box was shipped through DHL and I got it 5 days after it left Hong Kong. If I sourced these from Ebay, the power supply, the frame, the bearings, the heatbed, the glass, etc. I would definitely spend more than $499, let alone the shipping (didn’t pay any import tax). The support from Han is prompt and he is really willing to help.

    In general, I would recommend this kit and it’s a good value for anyone looking for a Prusa i3 in Australia. Though be prepared to get a soldering iron (for heatbed thermistor and extending the fan wires) and crimping tool.

    I’m very satisfied with the kit. DHL shipping was extremely fast (next day! from HK to Europe).
    I assembled the printer before a manual for this printer was uploaded on this site. But by using manuals from slightly different printers it was quit easy and fun to assemble. It took me about one day but this was also because this was my first 3d printer. If I would have to assemble one again I think I would be muchhhhhhh faster.
    No part was missing and I did not need the rasp :-). The only things I bought was some cables and 230V plug with cable and a soldering iron.
    To sum up I am very very happy with the kit and also very satisfied with the print quality.

    I managed to destroy one bearing but it was completely my fault:
    I downloaded some marlin firmware branch and did not really modify the configuration a lot which came with it because I thought I will watch and see what is happening and than adjust it. Sadly the speed of the Z axis was way to high and destroyed one bearing. After lowering the speed everything was good. So I can only recommend to check first before trying it out.

    My current setting which works good for me (but may be not for another printer???):
    #define DEFAULT_MAX_FEEDRATE {500, 500, 2, 25}

    Fast delivery, good price, friendly contact, Prusa I3 kit ist relative stable though the frame is made out of acryllic sheet.
    Took me 4 weeks installation because software needs to be installed by your selfe. I use Repetier-host and firmware as well as slic3r or Skeinforge for gcode generation. Printer works quite well.

    I just wanted to submit a somewhat more recent review of this kit. I ordered my Prusa i3 on Saturday March 15th, and it arrived to New York City on Monday the 24th. Surprisingly fast shipping from China and I had no issues with customs. Over the last few days I have been slowly but surely putting the kit together and I have to say that I am quite impressed.

    Not only are all the positives mentioned above still true for my kit, but Czar seems to have deliberately addressed and corrected all the issues that have recently been brought up by others here and in other forums. First of all, the instructions and firmware are now posted here, which were all super helpful. All the tools fit and I had no missing components. Infact, they threw in alot of extra components such as nuts and bolts, and even an extra thermistor and Pololu board which was a huge surprise. As mentioned previously, the packaging is also quite impressive.

    All in all I have been extremely impressed and happy with the quality of this kit and my experience with it. The only possible room for improvement might be better pictures of the final assembly, more detailed wiring instructions, and a step by step guide of installing the software to connect it to the computer. I was also a bit confused at first about what to do with the included thermistors. All of these issues were eventually solved by searching online though, and in reality that is sort of the point of a kit like this anyway. Troubleshooting issues like these have taught me more about how this thing works, which is why I got a kit in the first place.

    Overall a great product and a great seller. Will definitely recommend it to others and would buy again in a heartbeat!

    Received the printer within 10 -15 days after ordering. Was able to assemble the mechanics with the instruction provided. For electronics assembly I has to go to Reprap wiki and other sources I googled. I am short of the DuPont connector (5 less) and the thermistor does not fit the heat bed hole comfortably. No wires for the end stops and thermistor. Luckily I had a long telephone cable which I cut into pieces and soldered up.
    After assembling everything, download Arduino from the net, marlin, and repetier from the net. Install Arduino and open the configuration.h file in marlin folder. For editing it watch this video.
    https://www.youtube.com/watch?v=PunmzTbY594

    After editing it, open the repetier you installed and go to manual configuration tab in the right side and try running it manually. If you get error with temperature in the frame at the bottom, then make sure the extruder heat is on and watch it rise.. Disconnect and reconnect as often as needed and make sure all axes are moving in the direction you want. If not go back to editing configuration editing in Arduino and invert the axes as per the video. Most of my configuration is as in that video. But my z axis motor is just vibrating but not moving the gear. I have to solve that. Would appreciate if someone could share their configuration file. I will after I am done calibrating.
    Thanks

    I received the printer after a week. I’m very satisfied with the quality of the parts and the price plus free shipping – there is no better value I think.
    I put the printer together quite successfully, but the documentation is incomplete. Luckily there are tons of reprap docs and videos out there, so this is not a problem. To this day I haven’t got around to correctly fix a y-stop to my contraption…
    Also the marlin firmware requires some tweaking. I had to find out the type pf the included thermistors for the hot bed (which is not a good fit, btw).
    I could go on and gripe some more, but the bottom line is this: this is a good kit worth your money and quickly delivered, but you need to put in some thinking and work in the spirit of the reprap community. Don’t expect something quite finished and ready to use.

    :

    I will second a lot of what has been said, it is a good kit.
    Documentation gets a little spars toward the end. For example the end-stops are pretty much absent from the docs as to placement. The firmware also needs some help as to setting up some the parameters. ie inverting axis etc. And figuring out a thermistor setting that worked (plus the kit one isn’t very sensitive and I should replace it). Also there are 3 motors of one size and 2 of another, you have to just figure out the two bigger ones go on the z axis (hopefully)

    My endstops are still pretty hacked together but they work and I am up printing plenty of quality parts.

    But in the end I will give it 4 stars, with a more customized firmware and a little better documentation around the end-stops and some of the electronics it would be a 5 star kit.

    Before I can rate the kit I need to finish building it. However, here are my current impresions:
    -The printer arrived my country (Chile) in two days, which is really fast.
    -Sales support has been very friendly and active.
    -It came with all the parts (except for some bearings, but I already had many of those so it was no problem).
    -Setting the endstops and firmware has been quite hard, but I’ve been following the guide in Cooking Hacks, which is quite in depth and can be used to assemble this printer.
    -I’m still struggling to find the right thermistor configuration. David D, could you please tell me what configuration you used? Many thanks.

    I purchased an Prusa i3 kit a few weeks ago, I’m in the process of putting it together. But what I want to tell everyone is about 3DPrinter Czar service.
    On April 4th , I went to czars webpage to check on the Statius of my order, the site was down, all I got was a blank page with the word “pageok”. I checked it again, the next day, got the same thing. So I sent an e-mail to find hot what is going on with the site. With in about an hour Han returned an e-mail explaining the problem and assured me my order was ok and being processed.
    A few days later the site was down again, So I e-mail again. But this time a short time later my phone ring, it was Han, and he said that they think the site is being hacked and said my order is fine and will go out in a few days.
    When I received my order, I received the printer, but not the filament I order, so I e-mailed. Later on in the day, Han, e-mailed me and said he order the filament from UltiMachine so I would get it soon., I should receive it today according to the tracking number.
    Now this is service, you couldn’t ask for any better. I would recommend 3DCzar to anyone. Thank you, Han. For the fine service.
    The only problem I fine with the printer is the directions, not so good, they could be improved.

    This is a kit of a design created by a hobbiest (prusa). You should expect to have to figure some things out for yourself. SInce I bought my kit the website has been updated to include more instructions which should be helpful. The packaging was very good and well thought out. The plastic parts look good too. I had a problem with the heatbed and Han worked to make it right. No problems getting responses to emails at all. If you want an i3 without having to shop for tons of parts, get this kit.

    So far best what you can get on the market for this price. I ordered mine more than month ago, it was shipped in one week, and it arrived after 4days (I’m in EU, Slovakia). Awesome packaging, I can hardly imagine that something would break during the shipping. It tooks me maybe one week to get it fully assembled and properly calibrated. There was also problem with leaking fillament from the pre-assembled hot end. But since all it takes to fix it was to tighten two screws, thats not negative aspect for me. The printed parts required quite a bit sanding and was not so pretty, but who cares since you can print your own right away. All the tools that comes with the package were really a great help, and basically all you need to assemble, and maintain your printer. I’ve been printing every day since assembled the printer. For the layer high, I’m able to print at 0.06mm and I believe that this is the limit of this machine without further upgrades. For the speed, right now I’m printing at 100mm/s without any noticable decrease in skin quality (I’m printing even outer shell and first layer at 100mm/s and it really don’t make any difference compared to 20mm/s printing). I have not tested higher speeds yet, but I believe I can get it up to 130-150mm/s. This speed and this precision is really remarkable, actually better than in most ready-made 3D printers for 3000USD. So for THIS PRICE, and with the FREE and FAST SHIPPING, its really 5stars kit and I can’t say a bad word about it. Highly recomended!

    I ordered this 2 weeks ago and it arrived today which i consider really fast for free shipping! It was packed very well and made a good impression from the start.
    Ive built the mechanical part which went very easy, the instructions are a bit lacking towards the end, but only since there were some more parts in the box than in the instructions. I have to figure out what i’m gonna do with them still.
    I can only recommend this kit! Very good value for the money!

    “Compared to its predecessors and other RepRap machines, Prusa i3 is known for its extreme ease of assembling.” ” In our experience, the Prusa i3 can be assembled within 3 hours, making it ideal for first-time RepRappers.”. These quotes are very misleading. Perhaps a first-time RepRapper can put together the frame in three hours, but there’s about 20 hours of wiring, sodering, crimping, etc. after that. This is a huge project if you haven’t done these things before. Educate yourself on what’s required, and know what you’re getting into before purchasing.

    Good kit but as others have mentioned the instructions are not so great, specifically the location of where to place the endstops, firmware configuration (although there is a good post in the forums) and calibration. The mechanical build instructions start off well but taper off to nothing towards the end however there are a lot of resources online, especially on youtube that you can use to get it built. I only had one missing part that I was able to substitute with something else but that stuff should be checked before sending to customers. There should also be a comprehensive parts list so builders can check they have all the parts before starting and then finding they are missing something.

    It’s not so difficult to build, if you have done anything with RC stuff then you should be able to comfortably build this printer, it’s the firmware configuration and calibration that may be the issue for some people.

    Overall I am happy with the kit and the good service, especially the fast delivery, 4 days to Australia! Questions via email were also responded to very quickly and helpfully.

    Excellent kitset with great shipping. All parts were present. It does take a few more hours (15 odd including calibration) than stated as a first build but the frame goes together very quickly. There were a couple of small issues but these were easily sorted. My kitset had the black frame with the white printed components.

    Ordered the printer because it was best bang for buck. Parts rocked up after 4 days(and that was partly over a weekend as well which is just amazing). Kit was missing the threaded rods but one email and they were posted out the next day at no extra cost and, once again, only took 4 days to get to me. Instructions are great, and if you get confused at any point there are a million other Prusa i3 instructions that you can use to fill the gaps. Took almost no time to calibrate(just had to get the end stops right), and have done a few prints so far and they have turned out great. What can I say, best value for money 3d printer I have seen so far. Amazing service and an amazing product. Could not recommend it enough.

    Ordered the Prusa i3 in June and it took 1 week to be shipped from the supplier. Once shipped, it only took 4 days to reach my doorstep (I live in New Zealand). This is my first ever 3D printer and I’m really happy with the kit. All the parts were there on arrival and it was heaps of fun to build. The only mishap was that the power supply was damaged in transit, but a quick email to Han and he very understandingly sent me a replacement. The printer took me around 6 hours to assemble and I’m currently still wiring up the electronics but the whole process has been a lot of fun and a great learning process. Overall, I highly recommend this printer for any first timers or experienced reprappers due to its great quality and the fantastic service from 3D Printer Czar. 5 stars from me.

    Good price, fast shipping, no customs problems (Slovenia), no damages, everything included (at first sight). 5 starts for now.
