Bridging over infill with MatterSlice #55

Open whosawhatsis opened 10 years ago

whosawhatsis commented 10 years ago

I'm seeing a lot of holes in my top, flat surfaces with MatterSlice due to over-stretching the extrudate when bridging over infill. Sometimes with enough solid layers, the holes will close up, but there are usually still bumps due to the curling of the broken strands below. Slic3r used to have this problem until and a few of us convinced Alessandro to treat the first layer printed on top of sparse infill as a bridge, which works beautifully. By applying bridging speeds and flow rate modifiers, you can keep the strands from breaking so that there is something for subsequent solid layers to build on. Internal bridging allows you to get solid top surfaces more reliably and in fewer layers, and I'd really like to see this added to MatterSlice.

Let me confirm the problem. At a moment I have to increase # of top layers as to 15, 10, & 5 as for HQ, MQ, and LQ respectively but this does not look at a right solution.

I am seeing this issue as well, it is very apparent when I use .1mm layer height and 4 top layers.

It's a good idea and one that we will try to get in as an option for 1.5. 1.4 is scheduled to come out mid September and then we'll start to spec out all the features for 1.5.

@larsbrubaker for what version is it planned now?

johnlewin commented 8 years ago

We're still looking into this and hope to address the problem with a short term and long term solution. In the short term, to address the case where solid infill lands over empty space, we're thinking about running at bridging speeds and adding or more outlines around the solid infill. Hopefully coming in the near future
