Bottom of print not as expected

Recommended Posts

Hi all,

I'm hoping someone can explain what I am doing wrong here.

I uploaded some images in an Imgur album here:



As you can see, one of the flat sides is filled solid, without gaps. This is the top side of the print.

But the other one has a lot of space between the lines, and irregularities. This is the bottom side of the print.

The last picture is from the side.

I'm using a UM2 with the following settings:



I don't understand why the bottom side is so rough compared to the top side.

Can anyone shed some light on how/why this is happening?

Thanks in advance!

Hi and welcome,

I think that you need to level the build plate a bit closer to the nozzle.

The first layer needs to be squished more. In your case it looks like the first layer is not squished but rather "layed".

The first layer in your case looks like the lines are piece of round filament, it needs to be flat.

If the first layer is almost transparent you are to close, if the lines are not closed you are to far.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
