Description

The RepRap Prusa i3 was one of the earlier designs in the RepRap scene and quickly rose to become the most popular. It has a number of different variants and commercially produced versions including the Prusa Research i3 MK II by the original creator, Josef Prusa. A straightforward motion system allows for ease of assembly and customization and has the potential to create beautiful prints.

Prusa i3 Mk3

New to 3d printing, bought one from Amazon supposed to be all friendly, easy to use etc etc but had nothing but problems so took the plunge and bought a Prusa i3 Mk3 and so far have been extremely delighted with it, took my time building it over a week, then setting up, had a few problems but think I have over come them and now starting to slowly test my printing out, made the tree frog that came with it, bulldog and Prusa logo, all good so far, now for some thing bigger, just have to wait and see how it goes but looking good so far..........................

Easy to use

I like the "skeletal" look of this printer. This makes it easy to replace various parts.

Amazed and Dazed.

Easy to assemble and get first print going.  Really appreciate the quality of components. First "real" print after a few calibration cubes (and online research for correcting setup issues) was a filament guide/holder.  Took a couple of tries, but finally figured out that my drafty garage workbench was not the right place to set the printer up.  Lots of little improvements (tweaks) are available via the internet and every one implemented so far has made this printer a little better.  I fully expect that as I gain experience and knowledge this printer will continue to impress me with its capabilities and value.  Very satisfied.

An inexpensive Intro to learning about 3D printing

Purchased the kit from China back in 2014. Cost was around £320 (including customs duty) and included 2 x 1Kgm rolls of filament. It was based on Prusa i3 but had an acrylic frame, not aluminium as the later ones moved to and it did not have auto levelling. The Z axis did have two motors with 'built in' lead screws (supposedly better than lead screws that are clamped onto the spindle). Kit was easy to put together and doing this gave me a good intro to how it all works. It also worked straight away! Have used it to print a few useful objects as well as many 'frivolous' ones. 

Overall it was a good buy at the time. But now I am looking to do some more intense/precise printing and  I realise ideally it needs better calibrating,  larger prints have the habit of warping, the Z axis motors started 'skipping' (and finally jammed) and ideally one needs auto bed levelling. However, so far I have been able to correct the jammed motors (stripped down and gunk removed from threads and inside motor) and am planning to build a simple enclosure (to get more stable temperature to hopefully reduce warping) and to add auto levelling. Also need to perhaps straighten the Z axis lead screws as these may cause some skips plus see if the nema 17s should/could be plugged in to two connectors (the board has an extra E1 socket that Marlin could make a Z2 socket). Again this is proving to be an interesting learning experience.

I did print and install two filament guides. One allows filament to loop to top of machine then down to extruder and reduces any strain on filament when executing fast moves (occasionally I had filament breaks). The other sits in extruder and allows the use of flexible filament. Also printed some cabling bracketsto tidy up the runs and some 'hold down' brackets to screw printer and filament holder onto a base board.

Pros: Price; Good Quality; Instructive; Lots of data on web; a few spares provided and mostly commonly used parts that are easy and inexpensive to source.

Cons: Lead screws slightly warped; No data for Arduino board used (so will be making a guess).

One other positive for me is that it has got me interested in all aspects of Arduinos, 3D design, general CNCs, and even programming in Python. All good to keep the brain ticking over!

It is a challenging 3d printer but it taught me a lot through trial and error.

I feel for the price it is a great way to see if your really into printing 3D models.

The long and winding road

The build took a few days. The first few prints went great. Needed some tweaking. Tweaking led to flashing firmware, which led to breaking the heat bed and have no LCD. Once I actually found the correct firmware and replaced the heatbed everything works again. Now I’m back to tweaking the print settings as my prints are not very pretty. 

Great way to learn how to master a 3d printer as well as learn and practice A LOT of patience and trial and error.
