This Prusa I3 A pro 3D printer is streamlined and optimized based on the previous Geeetech Prusa Aluminum I3 3D printer. This Prusa I3 A pro has the following features.

3-in-1 3D printer control box

As you can see, the most obvious modification is that we add a 3-in-1 3D printer control box for this Prusa I3 A pro which gathers the motherboard, power supply and LCD Cpanel in one box, saving the space taken by the printer and bringing you a neat and organized desktop, most importantly, the power supply is installed inside the control box now, which is not only for protecting the power supply, but also for eliminating unnecessary dangers, protecting your family and your pets.

Higher transmission accuracy of Z-axis

Z-axis adopts high-precision lead screw which is able to convert rotary motion to linear motion. The lead screw features high accuracy, reversibility and high efficiency. It can achieve accurate micro-feeding to ensure printing precision, and high-speed feeding to ensure fast printing speed.

Easy assembly, easy debugging
High precision machined parts and well-designed mounting holes make the installation process simple and fast. The control box is already assembled by us, what you need to install is only the body, which saves a lot of time for you. The detailed assembly manual makes your DIY assembly easy and time-saving. Detailed instructions provide you with convenient debugging guidance.

Reserved design for upgrading
In consideration of your need to upgrade the extruder in the future, we use reserved design on this printer and you can upgrade any part. This kind of design provides you with more choices of revamping this printer and more ways to use it.

Visible parts, convenient for trouble shooting
Compared with the box-type printer, Prusa I3 3D printer DIY kit is more suitable for starters. All the parts are visible, and you can easy access to those parts. It is very convenient for for trouble shooting when you are using the printer.

    I bought this printer a few weeks ago and just want to say how impressed I am. The quality of all the parts, especially the aluminium frame, is really excellent. The kit was very carefully put together and all parts were present (one or two extras). Construction is certainly not simple but was a lot of fun. A bit of tweaking was required to get the z-axis to run smoothly from top to bottom. It has everything you need to get started, including a length of PLA filament - very helpful. I'd just like to thank all the people at Geeetech for all the time and care you have put into the design of this machine, and creating the kit. I'm really enjoying creating things with this machine.

  • william docarmo | 08/07/2017

      Thanks for help but after downloading Arduino and the firmware, when I want to compile, the Arduino shows this error : " 'U8g_t' was not declared in this scope " I dont know anything of coding, and through google search, I've tried any possible way that others use, but nothing happens... Please help me the Arduino version that I use is 1.0.1 Thanks

  • samer masoudi | 06/05/2017

    Emergency, please help me!!! I've just assembled my prusa i3 a pro, but when I want to calibrate the printer and selecting "Auto Home" on lcd panel, first, the extruder goed left until it touches the end stop, then the heatbed moves toward me until it strikes the front panel of Y-Axis and never stops, then I have no choice but to press the "Emergency Stop" button first I thought it has little space to move so I move the frame to front a little, but the broblem still ramains sorry for my bad english and description of problem PLEASE HELP ME ...

  • Shane Volpe | 05/31/2017

    Do you have instructions on how to properly wire in the 3DTouch Auto Leveling Sensor to this unit? The current instructions on your site assume all the servos and limit switches are wired directly to the GT2560 and not through the breakout board used by the 3-in-1 3D control box. The Z Max limit switch on the breakout box is only 2 pin where as the 3D touch requires 3 wire. Can it be done with the breakout board or will I need to disassemble the 3-1 3D control box and directly connect it to the GT2560?

    • Zina Luo | 05/31/2017

      Hi Shane,you can email to our technican for help:technical@geeetech.com

    • Paul Ellison | 06/30/2017

      Hi Shane, Not sure if you managed to get a response to this from the 'Technical' department (I certainly haven't so far). Ended up taking matters into my own hands and finding a workaround. I'd be happy to help you if you still need it. Now struggling with firmware, where the probe positions are being ignored, and the Z axis just runs itself into the ground.

  • Nico van Gessel | 05/08/2017

    I bought this printer around two months ago and so far I've been very satisfied with it. However, I would like to add cooling fan because I faced some problems with bridging gaps and printing overhangs. Can you please assist me here? What kind of fan do I need (2-wire or 3-wire w/ PWM)? What port on the control board do I need to plug it in and how do I integrate it with my slicer (Simplify3D)?

    • Zina Luo | 05/11/2017

      Hi Nico,could you pls list send email to me and i can list the detail to you:zina.luo@geeetech.cn

  • Ron Hatcher | 04/25/2017

    I really love my new A Pro printer, I have probably 300+ printing hours on it already within a couple weeks. It has run almost non-stop without a single problem. I must admit I still have a lot to learn about printing and print quality but this little unit its been a trooper so far. Be forewarned that building could be challenge especially if your not mechanically inclined, but i think there is plenty of documentation with the unit, on the Geeetech Website, Youtube etc to get you through it.I am impressed with the quality for the price I paid. Right now I am about half way through a 53 hour printing project and not a hitch. My comments come from me being a first time 3D printer owner but I do have a whole shop full of CNC Milling, Plasma and turning equipment. I would confidently buy another one or refer a friend. I did switch Cura as a slicer because it seemed more strait forward and less complicated to me. I started with Slic3r but changed the wrong thing or something and couldn't get it to go back to the original and it was doing terrible things in the slicing department. Cura made all the difference me being the beginner I am.

    • Zina Luo | 04/26/2017

      Hi Ron,glad to hear that you like this printer and thank you for your feedback here.

  • Andras Csikasz | 04/23/2017

    so in the midst of getting my i3A pro set up to run the z axis is not cooperating tried severl things rods bent? threads? everything seems ok what the trick?

    • Zina Luo | 04/24/2017

      Hi Andras ,could you pls list your problem by detail with some picture to my email :zina.luo@geeetech.cn?

    • Dean Brown | 05/20/2017

      I had the same problem and have read were others are seeing the same issue.I found that the stamped steal Z Axis guides and the Z axis motor mounts are not perfectly square when all items are tightened. I losened the 4 screws that hold the threaded brass mount on both sides till it could self level as the threaded rod turns. This fixed all the jitters and the sticking problems.

      • Zina Luo | 05/23/2017

        Hi Dean ,glad to hear that and thank you for your feedback.

  • Philippe Bouqué | 03/01/2017
