Geeetech Prusa I3 X

My Geeetech prusa like (I3 proB - acrilic) is a delight. It came as a kit and after several hours of assembly (spanned over 2 days) I was intrigued that the axis did not moved - only X was homing and that was all. The geek kicked in and I switching connectors for motors and finally I have got X and Z homing but not Y so checking the stepper driver I was surprised to found that one pin was bent and after that - Eurika. My first print was a part for a spring operated car and despite everything it turned to be a functional, beautiful piece. The printer requires slow printing speed - 40mm/s for 0.4 up to 0.2 mm layers. 0.1 mm layers need 20 to 30mm/s and a fine nozzle (0.2max). The original printer head leaked during first print so I tried to fix this but I have broke it and ordered additional parts. After 2 weeks the extruder skipped steps during extrusion process so I had to add some reinforcements to the tension spring (2 washers). Now I can say it is OK - so as I do said you need to take the matter in your own hand, search the net and the Geeetech support forum and the printer is a joy (plus - it has metal parts on X axis and you can always print plastic ones with additional features ....)

Very simple printer!

Its my first 3D printer.  I was frustrated at the beginning of my choice. However, I found a lot of tips and information for this printer.  Now I've come up with my printer, and that's awesome :)

The price point for these printer kits are nice. We also don't mind building our own printers but some may find it a difficult job. The parts included with the printer were not correct and it required replacement parts to be shipped from China. Kind of a pain due to shipping times. We have a small print farm and this printer sits stationary while all the other makes and brands of printers run 24/7.  The printer also had Z banding issues that could not be cleared up. The fix was after market parts, a few printed parts and some custom firmware changes for the new Z rod thread pitch.

I was given this printer for free by someone who bought it first hand. It was originally assembled incorrectly so I had to spend time putting things right. The community for this and similar printers is good and help is readily available. So far I have had mixed results with printing, Some things come out well and some things don't make it to the end of the print. I think this is a good printer to get into 3D printing with to learn how everything works if you don't mind adjusting things.

I had one when I was a child.  A small, meths-burning Steam Engine that needed constant tweaking and knob-twiddling. It would sometimes run perfectly for a whole session but the next time , although unchanged, the settings just wouldn't quite cut it. 

My Geetech Prusa I3 Pro B is a bit like that.  It needs to be warmed up before the settings are correct, and it seems like even a change in the weather can affect it.  When it is dialled in though, it is actually a really good little printer. 

Mine is screwed directly to a heavy wooden table to stiffen the frame as much as I can, and I have replaced the threaded bars with lead screws. I also printed the usual replacement motor mounts and frame braces and added those. 

What I have now, I believe, is a match for some of the much more expensive models around. This altogether brilliant little kit has inspired me, and I'm sure many others, to  embrace the concept of 3D-Printing.

I would give it a solid 9.5 out of 10, with the half-point taken away for the time I spend with it instead of walking the dogs. 

Great printer for the price of that moment (Though if i had to go for a new printer now, I´d rather go for a Creality). With time pass, it needed a bit of maintenance and improvement.

Original bearings are pretty bad, should change those before 200 hs of use or so, ay least for X and Y axis. 

Original heatbed connectors also tend to fail, i've changed that for common "plug-in" screw terminal block connectors.

----

As for improvements/upgrades to achieve much more printing quality:

I have completely fixed the printer to the flat shelf where it lays with big cable ties (Highly recommend this, great ridgidity and estabilty improvement for this printer!)

 i`ve also changed the common M8 threaded rods of Z axis for  T Type Lead Screws and better quality Shaft Couplings for that threaded rods (Common Shaft couplings tend to bend with time and produce "wobbling" on outer shells of the printed object).

---

Other:

I never could make the PWM fan output work, I don´t know if it came broken or I broke it trying to connect a fan...

---

By now it already has 800 hours of printing (With the maintenance and Improvements mentioned above)

The z axis bars and the extruder need improvement. It would be nice to add a fan cooling down the filament just extruded.

The geeetech prusa i3 pro b is a fairly decent printer. I got the kit as a gift which costs now less than 200€. Out of the box, the printer is at least usable but with replacing some (to be honest, almost all) mechanical parts, it gets really good. I am very satisfied and don't want to miss it.

It's no comparison to a real prusa but for less than a fifth of its price you get what you pay. 

Mi primera Impresora, muy conforme, es simple y económica, perfecta para el uso  domestico y diversión que le estoy dando..
