I did some prints with kisslicer the last days.
I think you are right. There are some things where I think they (or he, don’t know the team) had a good idea, but on other hand kisslicer is lacking some development on other features…
Things I have noticed compared to Slic3r:
.) Seam hiding makes the seam position smooth with the surounding perimeter, whereas it’s a little bit pronounced with slic3r prints. But beside this, the seam doesn’t look better as the slic3r one, I thought it can be better…
.) I love the layer preview with the possibility to move the “time” (nozzle travel) for each layer.
.) The print time prediction includes values for acceleration, it seems to be quite acurate.
.) Before it’s doing the solid top infill, it will do a single layer withinfill hat higher percentage. This improves the surface quality with lower top layer count.
.) Very good control to retractions, it gives you more options as slic3r with FW retract.
.) Default for support is 50% infill before real part is layed down. I think that’s a nice alternative against the solid infill used by slic3r, but I wasn’t able to see an advantage in quality.
.) Very basic cooling logic against Slic3r, but should be good enough for most cases.
.) The interface is not very comfortable, it feels like they started with a simple layout but the options increased over time and development. Manipulating a part (orientation, grouping of parts on print bed, …) is not very intuitive.
.) Seam hiding is nice to flatten out the seam, but kisslicer does a very bad job in hiding the seam position in corners. Compared to Slic3r, that means you have nice flat seams, but you can see it. Slicer has not as nice seam, but there is a good change you will never see it on most parts because they are somwhere inside a corner…
.) No bridging flow factor, no fan setting special to bridging. It might be very hard if you need nice bridges…
.) Bridging angle over gaps is not rotated to get the best result, it will do simple 45°/-45° pattern.
I will keep it for special parts, I think it will replace also the very few cases where I use Cura at the moment. But Slic3r is staying my No 1
