There are lots of free apps out there to get you started. You're probably wondering what would I do with a scanner? Well, for starters you could take a 3d photo for reference material & if you had a 3d printer you could print specialty parts, like a nose.... The technology is almost there.... its getting so close! I also just wanted to share some info on whats free. "Qlone" is a free scanner app you can use on your iPhone but there is cost to export from. "Thingiverse" is also a free site with all kinds of 3d printing stuff that you can 3d print. So is "MyMiniFactory"... all free! "Tinkercad" is another one you can make parts/stuff all free. If you like working with clay making "Sculptris" is for you...it's basically free software that look like a ball of clay you can shape/form using their tools. There's also "Meshmixer", "Meshlab", and "Cura" to get you started & they too are all free. It doesn't hurt to check it out if this sound of any interest to you!
