Faster infill / support

Recommended Posts

Posted · Faster infill / support

I had an idea the other day for speeding up prints drastically and it doesn't seem anybody building slicers is doing it...

 

Since infill and support areas don't benefit from very thin layer heights, wouldn't it be possible to speed up printing of objects by printing the shell and infill/supports with two different layer thicknesses? For example, printed the shell at 0.05mm, but the infill and support could be printed at 0.2mm every fourth layer, skipping the other three?  So three layers of just the walls/top/bottom at 0.05mm, then a fourth layer of the shell (also at 0.05mm) as well as a thicker (0.2mm) layer for support material? Or some variation on this idea?

 

As far as I can tell this should be possible, but nobody that I can find has implemented it as a feature. There are possible implementation details that would have to be taken into consideration (say, for example, a wall slants inward, preventing access to the infill area below it), but I wonder if this is worth looking into?

That feature is already part of cura.

 

But keep in mind that if you are printing somethign with vertical walls like a cylinder or a cube it works great.  But if you are printing something with any sloping surfaces (not vertical and not horizontal) then the infill will match one of the shells but not the other.
