3 printers, 3 failures


I have 3 3D printers. I don't know how I ended up with 3 but here I am. I have 3 cheap 3D printers. And it annoys me. Cheap DIY printers are really good for learning. And I have learned a lot. But they are not good for every day 3D printer when you just want them to work.

Yesterday I was sketching a few parts for the kit of BRIO MEC that my children are playing with. I wanted to print a few simple pieces which do not exist in the kit and I think should be there to make a few new construction possibilities.

So I fired up my 3 printers to print 3 pieces at the same time. And I got 3 failed prints.

To the left is a piece from the Mini Fabrikator 1, which also goes under the name TinyBoy. What happened here is the build plate is sticking to the guide bars, and the belt skips. I had this problem in the beginning so it is not new. But it will need some work to clean it up.

In the middle is a piece from the Malyan M150. It is not visible, but the piece is warped. Not really the printers fault, this PLA material warps and I don't know why. Aside from the material issue here, what annoys me most about the M150 is that the bed is unleveling "itself" with time and I have to spend to adjusting it regularly. Not something you have time for every time.

To the right is a piece from the Fabrikator Mini 2. The main issue with this piece is that it is missing its first 0.5mm. Simply because the Z-axis anti backlash is flawed in design and the X-axis gantry is not running smoothly on the guide bars.





After this I will really start considering getting a better printer and selling/giving away some of the others that are to unreliable.
