Nabeel: How did you get started with 3D Printing? 

David: I used dental implant surgical guides for guided surgery, it was costly and took a long time for the turn around from manufacturers, so I decided to take control of the process, cut my costs and shorten wait time to treatment day. 

Nabeel: What motivates you the most for your work? 

David: The ability to use 3D printing and guided cases to treat difficult complicated cases that are untreatable otherwise. It allows me to be more conservatiove and more accurate in treatment delivery and results.

Nabeel: As an endodontist, a root canal specialist, what unique challenges and opportunities do you think you have developing 3Printing solutions? 

David: Prototyping is the worst challenge I had. I have many concepts but I was stuck with traditional manufacturing and prototyping protocols, from trying to find a company to look at my design to prototyping it to getting an actual drill in hand to test it. Very tedious, expensive and slow process. 

Nabeel: What advice would you give to a smart student looking to learn about 3D Printing? 

David: The sooner you get into 3D printing the better. Start small but with room to expand, try to print different things, for dental and fun purposes. You’ll learn something new with each print, especially in the beginning. 

Nabeel: What were/was the best investment you made of time or money in 3D printing/bio-printing/bio-fabrication? 

David: Buying my own printer, it allowed me to print over and over again and try different things and allowed me to get instantaneous results. 

Nabeel: What do you enjoy in your spare time? What are you passionate about outside of your work/3d printing? 

David: Playing Golf, hiking, offroading and outdoors activities
