3D scanner app for makers and engineers

Hello,

I’m currently working on a mobile iOS scanner app for makers and engineers with a high precision and accuracy. I think this project can be useful for many people and I would love to have some insights. The use case I’m thinking are for example spare parts replication or where you can engineer a new air box for your engine to fit, a real engineering tool, where you can place scale bars in the scan region to get accuracy.

I wanted to ask if anyone has made some good or bad experiences with mobile scanner apps? Do you use the more expensive laser or lira hardware scanners? Or do you prefer to build all your models you 3d print from scratch?

I would really appreciate your suggestions and ideas.

are you looking at using the iphone 12 pro lidar ability ?
Or simply by using a form of photogrammetry ?
