Three dimensional scanning has become an important technology for converting physical objects into digital information. Engineers, designers, manufacturers, educators, makers, and individual creators can use 3D scanning for applications ranging from product development and engineering to 3D printing, personal manufacturing, prototyping, aftermarket development, and digital documentation.

Choosing the best 3D scanner is not simply about selecting the most advanced or expensive device. Different scanning projects have different requirements, and a scanner that is highly suitable for one application may not be the ideal choice for another. Object size, geometry, required detail, scanning environment, portability, software, and intended digital output all influence the decision.

A thoughtful evaluation of these factors can help users select a scanning solution that fits their particular workflow.

Understanding What Makes a 3D Scanner Suitable

A 3D scanner captures information from a physical object and converts it into digital data. Depending on the technology and workflow, the captured information can be processed into a three dimensional model.

The value of a scanner therefore depends on how effectively it supports the entire process from physical capture to digital application.

A suitable scanner should match the objects being scanned, the environment in which scanning takes place, and the purpose of the resulting digital model.
