Slic3r, a 3d printer tool

This, after years, is still my favourite slicer for the 3D models I print on the Prusa we have at the lab.

Easy to configure for newbies, easy to tweak in detail for hardcore users, and just works better.

And it has hexagonal filling.

This is the slicer we use at our makerspace. It has good user interface, and supports dual extruders. There have also been a lot of improvements in just the last couple of months.

I remember the day "Sound" first came into #reprap@freenode. Everyone was talking trash because it was coded in Perl...until they tried it. Skeinforge was so slow in comparison it was unreal. The first time I sliced an object with slic3r I was convinced it didn't work because it went so fast.

That was a few years back and I still prefer slic3r for the majority of what I print. It can be coaxed into slicing most things...but there are times I play around with different versions to get the desired results.

Best part of this software is that it is open and free. The wave of paid slicers is starting...hopefully more OS slicers come out soon.

I used to use Repetier Host to run Slic3r and send the serial signals to my printer, but over time I've grown to prefer Slic3r's interface, and now that it has OctoPrint integration (send to your Raspberry pi print server wirelessly), it's the only application I need on a computer to print on my Reprap.

We use this at our makerspace. The only complaint I've ever heard is that it can do a better job at scaffolding.
