CAD/CAM Solutions:What’s Right for You?

Sam Wainwright

“Intellectual growth should commence at birth and cease only at death.”

1 - Acquisition: Desktop and Intra-oral scanners

2 - CAD:The software used to design

3 - Manufacturing:Subtractive, additive, and materials

What questions should I ask?

• Are my materials locked with codes / RFID tags

• Does the CAM software accept .stl files

• What kind of CAM software is equipped

• What size of material does it use

• What Indications are supported

• What machines does your company use

Open vs closed
