What do you like best?
I like the number of print settings available to tweak for best results. I also like the quality of the sliced print as it, for some reason unknown to me, seems to always be better than alternatives like Cura.
What do you dislike?
I dislike the lack of tree supports or automatic layer heights. It would be nice to at least have layer heights generated automatically based on the curvature and detail of the various parts of a 3D model to save on plastic while retaining quality.
Recommendations to others considering the product:
The price tag's a bit steep but if you need an easy-to-use piece of software that gives you plenty of control over your settings, as well as great slicing quality, Simplify3D is the one to go with.
What problems are you solving with the product? What benefits have you realized?
Simplify3D has worked well to allow me to 3D print high quality objects for sale or personal use. It's given me a simple-to-use environment to grow my business avenues and solve many problems.
