15 reviews for RepRap Guru DIY Prusa i3 V2 3D Printer Kit

  1. Rated 5 out of 5

    I bought this kit from Amazon after reading reviews on several different versions of the same machine. It showed up packaged nicely. Everything in boxes and labeled baggies. My kit ended up shipping with one less end stop switch than required but after sending an email, I had a reply email the following morning with a USPS tracking number.

    At the time I received my kit, the directions and videos hadn’t updated to include the differences with the i3 v2. They are pretty subtle, but left me scratching my head. Overall, nothing that was difficult to figure out. Be sure to download the PDF files AND watch the assembly videos. Pay attention to the notes which pop up on the video.

    **NOTE** Although it IS in the video and directions, make sure your power supply switch is set to the correct voltage for your area. Mine came set to euro power vs US power. It would be a pita to set it once you have it mounted

    The only real “issue” I ran into was when my extruder was putting out very low flow of filament. I tracked that down to being a loose set screw on the gear which is mounted on the extruder motor shaft. It is located behind the fan and heat sink. An easy fix but a little frustrating during the troubleshooting phase. Once I set that, the printer has been fantastic. I spend more time on thingiverse now, wondering what I NEED and MUST print next. Looking at everything plastic around the house, seeing if I need to upgrade them.

    Good times.

    FWIW~ I have only run hatchbox 1.75 white PLA through mine. I’m amazed at just how far a 1KG roll of filament will go. ALOT of trial and error and printing of goofy things and I might be half way through the first roll.

    As many others have noted via Amazon comments, customer service is local in the US. Very easy to deal with.

    It’s incredible how far technology has come! After some research and understanding my budget and wanting to build my own, I’ve settled on the Prusa I3 V2 from reprapguru.

    It took approximately 6-7 hours to take my time and build the unit. The only issue I had was the x-axis slipping. I removed the extruded and belt first. Then I ran the bearings back and forth to make sure they were loose and free. Once I loosened up the ball bearings I reassembled and everything went smoothly.

    I would recommend starting with PLA. I made the mistake of starting with ABS, which is a little trickier. After about 2 hours of testing, I simply googled how to get it to adhere to the bed and everything started going easier.

    Overall for the price and experience, this is the Best Buy on the market.

    My wife bought this for me as a X-mas gift. I am very excited to have it. I assembled the majority of it on X-mas day, then finished it up over the next couple days and made my first print 2 days ago. I was even more excited when after only 3 tries I was printing very nice quality calibration cubes. I recommend this printer to anyone who likes a challenge to build something and have it work when it is together. Quality of printing is definitely proportional to amount of time and care put into assembly and setup of the machine.

  4. Rated 5 out of 5

    This printer was the best value for money I could find. It only took me a few days to put together and set up and just like they say I didn’t have to cut, drill, or solder anything. All the pieces come well labeled and are of excellent quality. Once it was all set up, my very second print worked perfectly. And the first failed because I’d messed up a software setting. Overall I am extremely happy with this printer. I would (and have) reccomend it to anyone even slightly interested in 3D Printing.

    I received this as a gift and had a blast putting it together. All the parts fit together nicely and the video/pdf guides were tremendously helpful. I had to drill out one of the x-axis ends, as was mentioned in the assembly guides, but it was very straight-forward. It took a bit of tinkering to set up the configuration files and get everything to home in the right direction. I was a little worried about the stability of the acrylic frame, but the first print went well and there didn’t seem to be any shaking of the frame during the print.

    I haven’t had a chance to use the printer yet but the build went fairly smooth. There were two small issues I will post here in hopes of helping others. Issue 1 – I had problems getting the X carriage together. As others have said, there is a known issue with flashing in some of the holes. This was true on the motor side for me. After drilling them out it still wouldn’t fit. Called support and they told me they used to have problems with this but was corrected when they started chamfering the rod ends. I took the carriage back apart and found that only 1 end of each rod was chamfered. As luck would have it, I had the square cut ends of both rods in the motor end of the carriage. With the holes not being very smooth, the rods wouldn’t fully seat. Flipped the rods around and gave it a GOOD whack. Problem solved. Issue 2 – I struggled a lot getting the X carriage belt into the block. It is a VERY tight fit getting both ends in there. I used a drop of dish soap where the two ends of the belt ran next to each other (not where the teeth of the belt and block mesh). Then used a flat heat precision screwdriver to push the second end in place.

    I got this kit as a gift and it is great. the build manual couldn’t be more clear and specific and really helped while assembling. also the frame is more sturdy than I originally thought and looks great to. would recommend this to anyone.

    I have been very happy with this purchase so far. Overall the build went very well. I mixed up the x end stop with the z end stop, so when I tried homing out the x it kept going. Also, I had a hard time setting the current limiting potentiometers so my z axis wouldn’t move. But once I got that figured our it was smooth sailing.

    I will definitely be recommending this DIY kit for anyone I know interested in 3D printing.

    This is a fine kit. This was my first 3D printer I purchased after doing a lot of research. Please remember- “DIY” is DO IT YOURSELF. I would suggest planning the better part of two days to get the kit setup and powered on. Then, plan for a full day to setup the software and get everything working correctly. You will need a volt meter and a lot of patience. Lay every part out so you are sure using the correct part during assembly, assembly is much easier than disassembling to swap a wrong part!

    Within one week of setting up the printer and software, I was up and running very well. I needed tech support two or three times, and they always answered my questions and stayed on the phone with me until my issues at the moment were resolved.

    When building this kit, here are my recommendations:

    -follow the provided instructions carefully…read them ALL first.

    -get your end stops set up correctly from the get-go, otherwise you will run into problems until they are correct.
    -I had to turn the “non-print” travel speed down a bit from the recommended settings, not a big deal, but it made a huge difference in the quality.

    -carefully set your MAXIMUM X and Y travel during printer setup! For unknown reasons, my extruder hit my bed leveling knobs at full 200mm of Y travel. I set my maximum Y at 185mm in the software, and all is perfect. I lost a little in the max Y area, but I don’t print anything that big anyway.\

    -most printer issues have to do with bed leveling, and extruder temperatures. You do need to level your bed OFTEN, and check flow rate on the extruder/filament. I check my leveling before every print. It only takes a couple of minutes, and saves a lot of headaches and filament.

    Overall, this purchase has been a fine experience. If I need a second or third printer (and probably will), it will be another printer from here…no doubt.

    I purchased this kit from RepRap Guru and received it in two days. Everything was carefully packaged and clearly labeled, which minimized confusion during the build process. It took me about 10 hours to completely finish the kit, which I was happy with as this is my first 3D printer. The written build guide, as well as the videos, provided enough information to easily complete the build.

    Once I got the printer operating, I had good results using the recommended Slic3r settings. I do have to use a glue stick to get prints to stick to the bed (which is common). After some software tweaking, my prints have gone from good to great.

    Overall, I am highly satisfied with this kit and would recommend it to anyone looking for a capable, affordable 3D printer.

    This was the printer I decided to purchase as my first 3D printer. I read that the Prusa i3 was one of the better rated printers on the market, it had a good print bed size, and a seemed to be fairly capable. To save some money I decided to purchase a kit and build it myself.

    The printer arrived in 2 days and I assembled it over a week spending an hour or two each day. The instructions were good and supplemented by the YouTube videos well. I didn’t have any major issues with the assembly. I’d recommend finding some photos of a completed printer to help guide you in addition to the provided instructions. This will be very useful when you reach the part where you need to route the wires to the controller boards. Extra zip ties and wire loom are good things to pick up for this part.

    After construction was complete, programming the printer was the easiest part of the entire process. Make sure you follow all of the instructions on leveling the print bed to the letter. If done correctly, your first print should come out well. With minor adjustments, they will come out great.

    If you are looking for a good starter printer, don’t want to break the bank, and are willing to try your hand at building a printer yourself, this is the one for you. Although I didn’t need to contact customer support, I’ve only heard good things about it online. (Which was one of the deciding factors in choosing RepRap Guru to order from). So far, I have recommended this printer to several people I know and would encourage you to consider it as well.

    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.

    This printer is awesome and the support from RepRap is on a par or better than Amazon! Like any DIY system you have to take time to understand the device and tune it but it is well worth it! There could be some improvements to the build manual but overall this is a 5 star product!

  14. Rated 5 out of 5

    Just got this kit a couple days ago and all I can say is wow!! This is my first 3D printer and I’ve always had an affinity for DIY so I decided to give it a shot! Following both the videos and instruction manual I was able to complete assembly and calibration in about 8 hours. I was amazed when the first thing I printed out ended up looking awesome! After some more tinkering with the calibration settings it’s even better! I highly suggest this printer to others as long as you have some mechanical and electrical inclination! And the customer support is also stellar. After opening the Repetier software I realized that the heated bed wasn’t registering a temp. I looked at the bottom of it and saw that the thermistor had broken off during shipping. I called the customer support number and within minutes had all the information necessary for them to send me a new unit free of charge. All in all, I love this printer and this company!

    I have been fighting with this printer for months. The extruder just will not consistently lay down plastic. Worked with tech support and nothing has helped. I would recommend buying a kit that at least has tension adjustment on the extruder. If you buy this kit, plan on spending money on a decent extruder.
