I tried my first 3D scanning today. A scanner I tried was not designed for face scanning, so I made a plaster casting before hand, then I scanned it in. The scanning process for my plaster face went really well. I could get a lot of details of it. Bug for my face scan and small doll scan, it was difficult.
Overall, it was worth trying it out even though I should pay 25 pounds for 2.5h fee.
I will try to 3D print once my data is well patched.
