This is a great value printer. I have the Geeetech i3 Pro B clear acrylic model (not the one pictured). For less than $200, you can get a fully functioning 3D printer. But that value comes at a price. You must spend more time assembling the printer from the kit parts and a lot of time tuning the printer to get those first prints working right. It took me about 5-6 hours to assemble the printer. However, I had it printing within the first two hours of turning it on. After learning how to level the bed and finding the right temperature for the filament/printer combo, I was up and running. The main part that needs to be added is a part cooling fan. Without it, the bridging is poor and prints don't always look their best.
The community around this printer is active on Facebook and online forums. Geeetech is a good company that provides decent documentation (they have a good series of YouTube videos showing exactly how to assemble parts of the printer). The PDF document gives step-by-step instructions on how to assemble the printer in plain English that is easy to understand with little translation required.
Some of the parts needed to be adjusted before they could be used, but I expected things to be a little out of sorts because of the cost of this kit.
It's a sturdy printer and works well plugged directly into my computer's USB port. I haven't used the SD card reader at all, so I can't comment on the print experience using that.
I've managed to print a few good prints, but my main issues have been severe z-axis banding. I ordered lead screws to replace the threaded rods that come with the printer. Unfortunately, the couplings that came with the printer did not work with the lead screws that I ordered, so I had to order some couplings. As soon as they come in, I will upgrade to the lead screws and hopefully get rid of the z-axis issues.
I was able to drastically reduce the z-wobble/banding by printing some z-axis fixer parts that I found on thingiverse.com, though. They allowed me to see details I didn't think were possible in a 3D print.
This is a good hobbyists printer, because it can be upgraded with lots of expansion parts. It's easy to print improved X axis carriages, z-wobble brackets, anti-vibration feet, z-axis assemblies, and on and on.
Overall, this is an excellent printer and I would highly recommend it for someone who isn't afraid to dive in and assemble a kit from a pile of parts and a few tools. However, if you're looking for a printer that you can take out of the box and have printing in an hour, keep looking elsewhere, because this isn't it.
