This is the 4th 3D printer I built. I first did an Ultimaker Original, a Vellemann K8200, a FLSUN mini Kossel and now this FLSUN Prusa i3. I find it a very good price quality ratio.

Still, it needs some skills and experience. While shipping is very fast, and feedback with the support also, I built the printer and found there were missing a few nuts and washers (there were more than enough in the mini Kossel). And also one end switch was not working.

Also, the provided heated bed showed not perfectly planar and the PLA won’t stick to it, neither cold nor warm, neither without nor with the provided tape. It definitely needs blue tape. And the glass bed should still be provided. Also a technical question ? why fix the X end switch to the moving extruder and not on the part with the screw ?

The hole broke when I screwed the switch in place. Details so I still recommend this printer.

Good printer. Well packaged and delivered on time. I would recommend that in addition to the manual to assemble it would be made and included step by step videos of armed. Thank you



After months of learning i am now able to print with this printer. It's my first and am really impressed with my prints given the price of this printer. I'm really happy with it.

The metal frame is really good, I´ve seen other printers acrylic made and this is awsome comparing to them. The X and Z carriage parts are not good designed for my opinion: Belt is not aligned with vertical bar, so tension in belt make Z bars to disalign and bend to inner side.

Printed parts are fine, just a more work than normal to fit some parts (using cutter is fine, but very laborous), but high quality in general. Screw kit is very good, also it comes with a lot more screws than needed.

Electronic board is good, but there is nothing about that on the internet. SD card is not micro as is picture. Not cristal like pics as well. Filaments included are normal, 250gr each colour. The worst thing for me is the ABS molded extruder part: is came completely bended.

The quality of the pieces seems to be sound, but customer support from FLSUN is wanting.

The pieces are sturdy and seem to be good. The instruction manual could benefit greatly from having someone who speaks English natively go over it to fix the "engrish" included. The pictures are ok, but having pictures in steps that show something fully completed (with no text/warning), can make one think they missed something.

I knew going into this venture that if I had any problems, contacting and getting an answer from customer service would be the tricky part.

Here is my review by category:
