Not only walls with 0% infill

Recommended Posts

Hi all,

I've been trying to search the forum for this quite some time, and in the past I've seen one post, but perhaps there is an update (I cannot find it anymore).

I'm printing a vase. With 0% infill and no top (switched off in expert setting). Also, set the width to 1,6mm (so should be printing 4 walls). When printing, my thought would be it prints only the 4 walls. However - it prints 'something' on the inner wall to. This takes more time, but also decreases print quality on the inner side.

Deeper examination shows also these extra 'printing' on the inner wall - I can clearly see the yellow parts, parts where it prints extra on the inner wall.

After fiddling with the setting in both expert settings found one solution:

- disable the bottom! YESSS! Great, yellow parts are gone, just printing 4 walls, low print time... but... I need a bottom in my vase, else water goes everywhere except staying inside and filling the vase with marbles will also give a nice effect when picking it up.

So... Is there a way to remove that extra printing without removing the bottom? One thing I also noticed, when enabling the top, the amount of extra material (yellow) is quite a lot more. In a way, printing the top and bottom influences this behaviour.

Especially for printing vases there is the spiralize or Joris feature in the expert settings. This results in a massiv bottom, very thin wall and no top. After printing the bottom the printer steadily increases Z, so it´s printing a very flat spiral. This results in very good prints without any Z-artifacts or so. Just activate "Spiralize" in the expert settings, look at it in the layer preview and print it.

make sure your top/bottom thickness setting is small enough so it doesn need to add any to the sides. Some infill is printed to make sure the shell is thick enough from the bottom/top point of view.

See the yellow inside this image? This is due to top/bottom thickness.

infill

 

 

EDIT: Oh... I noticed I read the thread to fast... My bad

Not a problem at all! I was thinking about this and I now understand why this is happening... If the height on the Z-axis is lower than the bottom/top height anywhere on the wall, it will compensate by adding extra material. My feeling it was infill, but it is the bottom/top fill. I wished this could be turned of in a way, I like adding strength to the parts by adding extra walls and little infill, but the extra time and material just makes it useless.

    • 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.
