    Everything from the packaging to the instructions was spot on. No problems in construction and they give you extra pieces…. cuz they know what its like building things at home. Make sure you follow some calibration videos on youtube and you will have no problems. First 5 prints were flawless.

    Great product. Arrived a few days before scheduled. I was able to build the printer just by following instructions which was great since I haven’t done something this mechanically involved for quite a while. I did have to call support a few times mostly because of minor things I overlooked and the average time spent on each call was less than a minute to get the issue solved. I was able to print some very complex models I’ve made with very good results.

    It takes time to get it all together, but it works out!

  4. Rated 5 out of 5

    I am fully pleased with this product. I had no issues putting the printer together other than some excess plastic in one of the brackets that house the metal rods and some instruction steps that I felt were out of order. The finished product is fantastic! The software was very easy to use configure by the instructions provided (I am someone who has no experience with 3D Printers prior to this build but am somewhat adept with computers and putting things together). To get to a finished state where I was ready to print took me about 3 days of off and on working, in total about 10-15 hours. Calibrating the motors, adjusting the end stops, leveling the hot bed, and leveling the X-axis took the most time overall so be patient, you will get it eventually.

    This was my first kit and it was a lot of fun. Putting everything together really gives you a feel for how all of the parts work and gets you thinking more about the design choices that were made and why. The kit definitely offers a great learning experience for anyone interested in getting into 3d printing. As for using the printer itself, the repetier software is very good and easy to use, and being able to set up a server with a raspberry pi makes printing fairly hassle free. The prints themselves come out really nice for such a cheap printer once everything is calibrated, though it may take a little bit of effort to get it printing just right, particularly with ABS, which I have had some success with, but getting ABS to stick to the glass bed is a bit more difficult than PLA.

    We got our second RepRapGuru machine 2 weeks ago so that my son could do some printing on his own. I wanted to say how happy I’ve been with the quality of the machine and the support I’ve received from them. Without question, their assistance both with technical questions and the few glitches I encountered remind me of what an American company is and does.

    Important: Use the YouTube videos to help step you through assembly, and refer to the most recent manual at the same time. It’ll save you some redo.

    One thing that occurred with both of our machines is that the belt drive gears were the wrong size. They should have been 20 tooth but we receive 16 tooth. This will cause prints to look squashed on the X and Y axis. A quick email to RepRapGuru and the replacements were here in 2 days. A friend of mine that I recommended RepRapGuru to, received his kit last week. His included the correct 20 tooth gears so possibly they’ve worked this kink out of the system. Just count the teeth on yours and if it’s anything other than 20, write to support to get the right ones.

    Having this machine has reignited my passion for mechanical engineering. It seems that usually the first obsession of any 3D enthusiast who can build their own machine from a kit is to set about improving it. To that end, I designed some parts just for the RepRapGugu machines.

    Here’s an X-Axis belt tension-er that is a drop-in part for our RepRapGuru machines… no cutting into the precious molded plastic parts to install it. Be judicious about how much tension… Apply just enough to avoid sagging belts and X-axis skipping. Too much can wear out your bearings or bow the Z axis smooth rods.

    I also remixed a wire manager for the heated bed. If you do not manage the wires coming off the heated bed, the constant motion will eventually snap off the soldered wires. It’s a mess, and preventable:

    Also there’s this piece to hold the bearing in place on the Z axis threaded rod:

    And so many more. Check out my collection:

    Lastly, my biggest hurdle was getting the crucial first layer to stick. I heard a lot of suggestions, so here’s mine:
    *In Slic3r, set your skirt to ~8mm to ensure the nozzle is fully primed before it goes in to print your object where it counts.
    *Use AquaNet (recommend Unscented) sprayed reasonably covering across the glass and let it dry clear.
    *Then set your height, while the heated bed is heated to your intended temperature. This matters! Doing it cold will frustrate you because the heated bed moves and flexes when heated. Start with 0.20 print height, which is the typical layer thickness. You can get real close to that by using copy paper folded doubled over onto itself. Since 1 layer of copy paper is ~ 0.097mm thick, putting two together will get you real close. Adjust the height so that you can just feel the paper being grabbed by the print bed/nozzle at each of the 4 corners. Then, the secret sauce is to take Kentucky windage on it. Try and print something that comes close to covering the print area surface. I created a square that’s 175mm X 175mm, and watch how it lays down the first lines. If they squiggle and come right off the bed or pull away shortly after (ABS!), raise the bed by half-turns on the thumb screws nearest the corners affected and try again. If it’s squashed flat and thin or no output at all, back off by half turn. Eventually you’ll settle in to a repeatable height. Expect to have to make fine adjustments if you switch materials that require different heated bed temps.

    With so many other choices out there, I suggest you stop right here, assuming you have some mechanical and electrical inclination, this company will walk the path with you through the process to successful printing.

    This was my first 3d printer and I’m 100% happy with my purchase. I got everything in the mail and it took about 10 hours to get everything put together and calibrated. One of the acrylic pieces was broken when I got it but I contacted RepRapGuru and was sent a new piece. Seriously awesome support!!

    The manual to put everything together is very thorough and I’d highly suggest paying attention to the details. Several times I ended up pulling apart something and putting it together correctly because I’d done something backwards (at no fault of the manual). By the time you get it calibrated you have a machine that you’ll fully understand how to maintain.

    I was initially hesitant to get started with 3d printing but this company and their excellent product put my mind at ease!

    I am very happy with this kit. Originally I tried to purchase the Chinese variant, the Anet A8, but it was on backorder. I am very happy I ended up with this instead. The instructions were very well written, just read the whole entire page before assembling. I had to take a couple things apart because I jumped ahead. The only problem I ran into was my heated bed was DOA. I called up support and I had a new bed in two days, can’t argue with that.

    Bought about a month ago and have been using it quite a bit, takes some time to get everything calibrated and squared away, but this printer has good print quality. As well this was my first 3d printer and would recommend it to other first timers.

    I truly love my DIY reprapguru 3d printer. I have printed many many things and even designed a few of my own to print. I did have issues on the build but were resolved with the assistance from the technical support team. They are awesome!!!

  12. Rated 5 out of 5

    For my first printer I think it’s awesome. Some acrylic parts were broke being shipped here in Japan but customer service was awesome and had new parts to me in a week. I’ve made a few changes and upgrades. Here’s a video for more on that . Everything worked right away and I haven’t had any hardware issues at all.

    I can say, if you want to save a good amount of money on a 3d printer, this is it. Every thing came nicely packed. If you read the reviews before this , it’s all said. Thank you Lawrence for the piece to hold that bearing.

    I purchased this printer last fall. It took about two hours to put it together and then an hour or so to configure, dress the wiring, and setup the Repetier host software. After making a few dozen prints I did not like the hysteresis of the Z-limit switch and painting the bed with dissolved ABS to get the prints to stick. I replaced the z-limit with an inductive sensor (made the bracket on the printer) and purchased a printing plate that require no coatings and minimal skirting around the part.

    I have tried to connect the Reprap display/controller, but I could not get the software and hardware to play well. I also used the Repetier web server for a few days through a RaspberryPi before giving up on it. I now use Octoprint (OctoPi) to print. I can fully control the printer and even check up on a print with an old webcam no matter where I am through the web.
    Oh, if you want a larger printing area or multiple heads, no problem with this design. You just need to get the parts you need.

    Bottom line, for the print area, cost, and flexibility you can’t beat this thing.

    In the World of 3D Printing and I still have some Money in My Wallet. Took some time to build the kit, instructions were good and a call or two to support (real person who speaks perfect English at RepRapGuru) filled in where my knowledge gaps were. In all, for the money this kit will get you “in play” and is a roadmap to learning about G Codes, Arduino boards, Slicer programs and other topics surrounding 3D printing – without breaking your bank. At the same time you will learn several lessons on patience, detail and ultimately obtain the satisfaction of building it from the ground up.
