I'd say not.
Maybe, maybe not.

As a professional design engineer I have had the pleasure of working with many different softwares over the years and every now and then I will try a free software, just for larks. Let me tell you, there is no comparison between free and paid-for. Yes, you can do basic designs with the free stuff but to really take your designs to the next level its worth it to spend a bit on software.

CA: you bought S3D, right? Why not just use the free slicers?
