Poor Quality 3D printed parts shipped with Original Prusa i3 MK2S

The Prusa i3 was designed by Josef Průša in 2012 with the Prusa i3 MK2 being released in 2016. The Prusa i3's comparable low cost and ease of construction and modification has made it popular in education and with hobbyists and professionals.

Poor Quality 3D printed parts shipped with Original Prusa i3 MK2S

Post by asteijn » Thu Jul 27, 2017 11:30 pm

I just received my Prusa i3 MK2S kit after 8 weeks of anticipating its arrival.

Unfortunately I am really disappointed with the quality of the supplied original Prusa Research 3D printed parts.

  • Lots of ringing and vibrations
  • Some stringing and ouzing
  • Poor surface quality (with scars)
  • Warping
  • Lines on side walls

Thanks.

Thanks Moorviper,


But its not me producing these crapy parts...

These are original Prusa Research parts I received with my brand new Prusa i3!

I guess I should send Prusa Research a guide for producing proper 3D prints.

The RAMBo cover is PETG and it kind of does that. Use a cigarette lighter passing it quickly over the wisps and they will disappear.

The rough texture on the ABS parts is their new textured bed surface.

The ringing isn't ideal but it's common. I guess they up the print speeds to maximise turnaround of printers.

Having said that, my (self printed) LCD cover has similar patterns in the sides, I think to some extent its intrinsic in the design of that part.

In my opinion, that's acceptable. Build your printer and print better parts of you are bothered by them.

I don't really see any issues. These are mechanical parts so printing them so they are pretty isn't really a big concern. None of this is going to impact the print quality of your printer.

I just finished building mine about a week ago. My parts where far from perfect too, but they did look better than yours (orange is perhaps more forgiving ?). But as others said, its not a problem, if you want, you can fix it yourself, and Im actually glad Prusa print fast rather than pretty, waiting 7 weeks was long enough! Everything fit together very well, and it prints flawlessly.

As for the surface finish; I was puzzled by that too. I kinda like the look, I hope they will disclose/make available their new print surface soon, especially as Im not a big fan of PEI.

oh, about the stringing; a lighter or heatgun will probably work, but I actually use a flame thrower (for burning weeds). Quicker than a lighter :p

As mentioned, the parts don't look perfect but they work just fine. I received my printer about 4 days ago and after assembly and some small adjustments, it was able to be dialed in pretty quickly regardless of the part irregularities. I also received the orange (in less than 6weeks by the way ;) )

Had the same kind of printed parts. No issues, had to smooth some of the holes for some bolts, but the only important thing here is that they are strong.
