How to print 3D Benchy right?

Hi fellows,

I have just printed 3D Benchy and most of it looks pretty nice. I tried it two times and everytime I got those "bumps" / "bubbles" on the left side of the boat and at the back. I did not slice it myself, I just used the 3D Benchy from the SD Card with Prusa Blue PLA.

What can I do to get a better result?

br... Robin

Every filament could be different made, so you have to adjust every print.

It could be bad cooling or to hot printing, or too fast printing.

Look for websites with mistakes in models or how to get higher quality, there are websites with pictures and what you can try.

If that's your result from the sample pre-generated gcode files, I'd try slicing and printing it with your own settings before worrying too much. I haven't checked recently, but many of the gcode samples dated back to 2018, and there have been a lot of slicer improvements since then. They're a good test, but you want to move off the pre-sliced samples as soon as possible. 

After you've sliced and printed your own version, compare and post back with updates and pics. Have fun with it!

Okay, when the moon is printed, 39h to go, i will change back to the blue PLA and slice an own 3D Benchy.

I just found it interesting and odd that that the blobs where just on right side of the printer / the left side of the boat. I will come back with new pictures 🙂

Thanks .. Robin

The main problem seems to be the cooling.

I had a modified cooling, looks good, also from technical view,  but .. well, with the original cooling no problems.

I tried also a self sliced GCode , same problem, same place. The gcode on the SD card is good.

Now Benchy prints fine 🙂
