you are a bit off topic but....
Printers are all the same, basically they feed a plastic filament trough an hot end and draw with the melted plastic, so you need to check for the following parameters.
Most important is size of print bed. An excellent printer but too small is not very helpful.
Then you have to check for material you want to print with.
Standard material is PLA, but you will find ABS (require a heated print platform) , soft filament (tricky to feed), soluble filament (very usefull but need a dual head printer).
Avoid printers that come with proprietary parts like cartridge for filament or nozzle, or special software, it is always a trouble and means more expenses.
Generic printers usually can be usually fixed/upgraded with generic parts for cheap. You would also find a lot of parts that can be 3dprinted. Generic printers are also more forgiving about accepting various filament.
Avoid kits if you never get such equipement assembled, All printers require some manual work (putting kapton tape on the heated printbed, making sure belts are correctly tensioned, cleaning nozzle, making small adjustment) and almost all require assembling a few parts out of the box and fine tuning.
Personally a got the wanhao 4x dual head. the print bed is large, that printer came almost ready and is simple to use.
It was cheap (800$). I print mostly ABS, a few parts with flexible filament.
most printers are x/y/z tables (different types, sometimes table is fixed, sometime head is fixed) , but if you print very high parts you can choose a delta-type.
The probleme with delta type is the head must be very light, so it makes very difficult to have dual head on this type of printer.
If you need to make complex parts, you will certainly need support. Support must be removed when print is finished, and sometime it is next to impossible to do a clean job.
Soluble filament are very good, because you can use it as support. at the end of the print you just need to wash the model with hot water.
but use of soluble filament for support require dual head printer.
Setting the bed height is one of the most tedious chores, and it's a good thing when the hardware makes up for small errors. I had to replace the bed adjustment nuts with nylock type due to loosening. You need to put some lock-tite on other fasteners to stop disasters.Reality is you'll have to do maintenance and rebuilding, so a kit gets you the assembly knowledge.
I find the makerBot works well.. it can max out its built plate with high precision and only the occasion malfunction. Just keep the heads clean!
I picked up a Cube 3 printer new in box for $100. They are going on Ebay for around $150. There are a lot of bad reviews for this particular model, but it's been a great printer for me. Using blue painters tape instead of the glue helps a LOT with the PLA prints.For the price I paid, and since I'm a beginner, this has been a fantastic 3D printer. Been using it almost daily for 4 months.
I'm also researching to buy one. For me, the most important is cost-effective and especially print quality!By my research, if I were to buy a filament I would buy the "UP Plus 2"; Because, in addition to cost-effective, the print quality of it and final finish is much better than the vast majority of this type of printer; Even more expensive printers. Already won even prizes!It also has automatic leveling and calibration, prints with ABS and PLA filaments, has a simpler stand-out support system and appears to be quite robust. etc. According to comments I read from Amazon buyers, some have printed hundreds of pieces on it without giving trouble and without decalibrating. Unfortunately, her print area is not one of the biggest.See, for example, this Youtube video comparing it to other printers and the print quality of it compared to the others: "Impresoras 3D: BQ Witbox vs 3D UP Plus2 vs da Vinci 1.0 (comparativa en español)"However, as I have an old DLP projector from Benq here unused; I'm thinking of trying to make a DIY project from a photosensitive resin printer; Which appears to have better quality than filaments, although it also has some drawbacks.
