Test / reviews: Geeetech Aluminium Prusa i3 3D printer

test-Avis-appreciation-critique-review-1 Everyone or nearly has already heard of 3D printers. But for those who still do not know what is a 3D printer, it's like a conventional printer that allows you to create your paper documents, except that here, it's in 3D! You can also choose the color, and even material! Generally, it is the PLA or ABS plastic. But you have also to metal, wood, etc…! A 3D printer allows you so many things (for little until time): create yourself of replacement parts, create works of art, create or copy action figures, etc… Short, I would say that the limit is your imagination (well almost, because printers do not print to infinity, they have predefined areas and certain technical limits depending on model ^^) having heard a lot about 3D printers and fascinating impressions that could get, I me to got a Geeetech Prusa i3 aluminum 3D printer!  

Why test the aluminum Geeetech Prusa i3 as a first test printer?

Why the Geeetech Prusa i3 aluminum as the first 3D printer? Primarily for 3 reasons:

  • The first is that it is relatively affordable price for a 3D aluminum printer level.


  • The second is that the Prusa i3 model is very well known in the world of 3D printing, so I knew that in case of difficulty, in addition to the Geeetech company, I can find information and assistance without too much difficulty on the net for it.


  • And the third is that, according to my research, the cheapest 3D printers are all in acrylics, but only as a result of the structure of the skeleton of the 3D printer be acrylic, the printer is very stable when printing! However, a printer, still makes good spurts! (Besides, printer paper, also!) All the tremors will eventually resulted in several problems of tension, torsion, calibration, detachment, etc… I already have a printer paper on an unstable table, which was shaking the printer from left to right with every print, eh well I can tell you that it took not very long to notice problems at the level of printing! So I decided to opt for a more stable printer directly and not start investing after in improvements or another printer afterwards.

Geeetech Prusa i3 Aluminium 3D printer test

  Because construction can take a long time, I write this article while building the printer, may so that there is not really well defined structure. So you see my findings chronologically ^^


The expedition went very well. When you open the package, you get a few slips: a booklet showing different parts and their quantity, a sheet containing the different characteristics of the printer, and 2 sheets stapled together which lists all the components. These sheets stapled are here to tell you that the contents of the box has been checked manually by a human being. As often in large parcels, it is not uncommon to end up with missing parts. The presence of these leaves gives the impression of quality and seriousness (and FYI, I checked well brands made it in the pen and no photocopies of leaves already checked) even though it may not be said if it is missing parts to err is human. But on one side, from a quick glance, you can see (if you trust them) whether or not there's a piece missing for example if it is not checked. Also note that because the name appears on the leaves, the company can slap on the wrist of the person who was supposed to check that everything was present20170722_194049! xD Note: notices are in English. Personally, I haven't even checked if a manual was available in french, as in all cases, the instructions in English would have been the most up-to-date and best explained, because usually it's from English that it is translated into french. But it seems to me that it is available in french.     The rest of the parts is separated by a block of foam separated in 3 floors.     I forgot to mention one detail: the Geeetech Prusa i3 Aluminium is self-assembly. It's cheaper, but it also helps to know his machine. And in case of concern, it is much easier to detect the source of the problem and fix it if possible.   Then, the package is very well protected by of the foams and parts by paper bubbles. The foam is thick enough and is separated in 3 floors.   20170722_19430920170722_19425020170722_194212   And level parts, we can say that it was worth his money: screwdriver to multi tips, protect-cables, a bunch of clamps, stem for filing if necessary, etc… and even a bic x20170722_194426D for the Assembly, well look at all the documents: issue, pdf, videos. Compare them between them. They have on each side of the errors, and given the number of screws, we can't blame them too much, as they change the printer over time. We also see in videos that they show is either identical or similar, and besides, the pdf that is often updated, indicates that this or that piece has changed. It is fine to change and improve the printer over time, but unfortunately, there is no indication of the version of the printer. At most, you will find a date here and there that indicates the last audit. It's especially bad for those who does not command at Geeetech directly and are likely therefore to have an older version (although I think that it would be fully functional without the improvements, but it's still a shame).   "What is funny in editing videos, it is that at times, you see the guy who said to himself" Ben shit! They are or the following parts? Or I put them? "And hop, he leaves to get them! xD or: "I screws it there, then it's there, I'm trying to insert it there" and there you have a hand that told him no, it's not this place!20170723_09304120170723_130936 xD gradually takes shape!  20170723_15171820170723_16164820170723_204616 Ah, worries, missing a screw! Not thought to check if the number of screws was correct or not. A Word to the technical support: Nickel, they'll send me!   Oh, and they have not thought of everything! It lacks a tool: to a hole in the rubber to screw the belt! Fortunately I had the gear needed, but it would have been nice to say. With such this kind of punch for leather, it works very well, it is with a tool of its kind that I have done: https://www.amazon.fr/Aodoor-renouvelable-ceinture-tournante-perforateur/dp/B01HPMTLGE and co20170724_200857ntinue editing!   When you see the number of threads, we understand th20170724_220054e number of clamps provided!   And here is the final versiogeeetech prusa aluminiumn of the 3D printer: then follows the programming! That way, nothing to say special, these are software that can practically use with any 3D printer, everything is well configured. Furthermore, a Geeetech error, is that in the manual, the settings are made for a diameter of 0.4 mm nozzle while the printer I has been provided with a 0.3 mm nozzle. This difference of 0.1 mm is change everything, a piece that looks like nothing, you have a beautiful printed piece!  


It was a beautiful experience to get this printer 3D yourself, it was very informative and I do not regret! The fact of do-it-yourself 3D printer makes you learn a lot about them, and allows you in case of trouble to discover the source of the problem, to fix, to understand exactly how it works, etc… Note that the Assembly did not necessarily a lot of time: by at my ease, it took me 1 day and 2 afternoon to mount from A to Z. In case of concern, customer service is on whatsapp and reacts quickly and helps you quite well (in English). I can't really compare in the face of a 3D acrylic printer, but little that I could compare with videos, this Geeetech aluminum really gives an impression of rigidity foolproof, I really recommend!   Link: https://www.amazon.fr/gp/product/B01N9DR8AY/ A note there also acrylic: https://www.amazon.fr/gp/product/B01DDNWLWU/ test-Avis-appreciation-critique-review-2
