#CAST (pronounced “Hash Cast”) is the new way to customize your broken arm cast with personal messages aggregated from your family and friends through social media. Using the latest in advanced manufacturing technologies and 3D CAD software, an arm can be 3D scanned at a doctor’s office and a one-of-a-kind cast made in a breathable nylon material using an additive technology called Selective Laser Sintering (SLS).
Blender is a free 3-D software that lets you create whatever model you want. Its difficulty is based on how well you know the hot keys. I like to use this program a lot with Garry's Mod to see how well I can make body armor or some kind of car part. I spend most of my time learning more about blender and what I can do with it.
