please, help me with printing quality

I have a Printrbot simple, a very precise 3d-printer.

But I always get crap out of it.

I tried Repetierhost with slic3r and I tried cura.

And I tried EVEY possible settings.

I found out that the problem is in the slicer software:

- while cura builds a perfect support like honeycombs with
very thin translucent walls
- it is unable to buld my mechanical parts in good quality.
(no matter how I try)

this is rather odd, isnt it?

After 2 month I am now on the way to resignation.

so let me tell you where the problem is:

the slicers out there slice the model into layers and then
- they look for polgons, perimeters,
skin, shell, meshes, infills and whatever !!!

How stupid is this!

Why do they work so silly?

Both the Inkjet printer as well as the laser printer
do not care about perimeters and infills -
they print black dots or leave the dots white
and they do it in a huge raster grid that covers
the whole page.

It is so really simple:

a sliced layer is nothing more than a
grid of black and white dots - thats all!

And the slicer just needs to find a path for
painting the black ones without painting
the white dots - nothing else.

If you need thin walls or very fine threaded rods
then all the existing slicers do create artefacts
from infill-shell overlaps and from infill-densities
that are less than 100% and they do and
many more evil things from "repairing the shell"
- the completely destroy the given bitmaps or pixelgrids!


I am very sure by now:

Would I print a model that is exatly the same as cura's
honeycomb support then it would print a mess
- because the slicer TRIED to treat the ultrathin
walls als POLYGONS!
HOW STUPID IS THAT!

And there is also a second issue:

Cura tries to build overhangs from outside-in not from inside-out.

(Them developers have NEVER EVER BUILD a balcony at their home.)

The slicers are UNAWARE of gravity!

It is really bad how much time I lost from
insufficient slicer software.

Now I need to know if skeinforge addresses these problems in
any ways, so here are my 2 questions:

1.) Can skeinforge print a 100% dense infill of each layer
WITHOUT generating a shell and
WITHOUT generating perimeters ?

2.) Can skeinforge print overhangs from inside-out by
looking at 2 or 3 layers below and by forward looking
2 or 3 layers above?
i.e. carefully expanding the layer's infill from a "save point"
(and possibly also a bit tweaking the involved layers.)

if so, please give me some clues how to set it up.

many thanks in advance

This is funny. A printrbot simple is not a very precise machine. It is a low cost machine that sacrifices rigidity for low cost.

No but I believe some versions of Slic3r will allow zero perimeters and infill only.

You can tell it which order to print all the paths but not individual sections.


For the thin walls the only program that handles them correctly is Kisslicer.
