To 3D Scan Or Not To 3D Scan?

Discover the optimal path to digitizing your parts with our 3D Scanning services. When faced with the challenge of replicating a part, we’re often asked if we can 3D scan it. While 3D scanning offers a powerful solution for part replication, it may not always be the most efficient approach.
Depending on the geometry of the component, (1) 3D Design (2) Photogrammetry or (3) 3D Scanning may be the best way forward. Our team navigates these options to ensure your project takes the most efficient route to digitization.
Photogrammetry
Photogrammetry is a process where we take a bunch of pictures of a specific object from different angles. We then use specialized software to turn those pictures into a 3D model of that object!
The advantage of photogrammetry is that we don’t need to use specialized hardware, it can even be done with a decent smartphone. The disadvantage is that it won’t lead to the best results for intricate geometries – it’s best used for more simple, anatomical shapes.
Often, manual 3D design edits are still required to come to a 3D model that can also be printed.
3D Scanning of Objects
3D Scanning is a process where lasers or structured light (patterns of light) are used to measure the shape and details of an object from every angle. These patterns of light are projected onto the surface of an object to create a super detailed 3D map of that object, a point cloud After scanning from all angles, the computer stitches these points into a digital 3D model.
Often, manual 3D design edits are still required to end up with a 3D model that can also be printed.
3D Scanning of People
Using the same 3D Scanning approach, it is also possible to scan larger objects or people. Similarly, these 3D scans will need to be manually edited to end up with a manufacturable model. In case of people, these 3D scans can be used to create e.g. 3D printed, personalized busts (unicolor).
