The Tevo Tarantula was going to be my first 3D printer purchase but I was reluctant to get a full blown kit because of time. When the Creality Ender 3 showed up with most of it being pre-built, it went to the top of the list for what I wanted to buy.
As in ANY 3D printer, you are buying into a hobby and hours of “stuff” that pops up.
Even with the issues that the Ender 3 brought with it, I would buy it again. I would encourage you to watch all the youtube vids you can on whichever printer you choose.
Here are the issues I encountered with my Ender 3 just in case you get that so you can know ahead of time.
Assembled frame wasn’t square. Very easy fix (just loosen screws and make square) BUT if I had assembled the unit with it not square, all kinds of fun issues could have arisen.
Build plate and Bed was concave. The center of the bed was about ~1mm lower than the edges. This will make adhesion difficult, etc. This was solved by purchasing a piece of glass. Hobby Lobby does custom glass cutting for frames, so I bought a 235mmx235mm glass (the actual size of the bed is not 220mm but rather 235mm, the store will need SAE inches for the cut). I will eventually get something else, but this was a simple fix.
Bowden tube coupling issue. I saw a number of post that dealt with this so I pre-ordered couplings and tube to have on hand. The printer came with an extra coupling. It turns out that wasn’t an issue at all, so I do have on hand extra stuff now for when it does become an issue.
This issue was maddening. The hotend had a 2mm gap between the bowden tube and the metal tip. The screw tube was completely wrong making prints impossible. I ordered a new all metal hotend but in the meanwhile while it is coming by rowboat from China, I completely tore down the hotend and repaired the issue. The tip doesn’t have the insulation tape on it, but it is holding just fine.
For the price, speed of assembly, ease of use and overall introduction to 3D printing (or expanding your 3D printer collection) the Ender 3 is a great little printer. Even with all these issues I am very pleased with this unit.
