The document discusses how 3D scanning technology has advanced rapid prototyping. Where previously creating 3D models through methods like 3D printing would involve using coordinate measuring machines (CMM) for accuracy checks, 3D scanning allows for faster, more precise, and more cost-effective 3D model creation compared to CMM. This has made rapid prototyping a more efficient process overall with high accuracy and precision.

3D scanning
• To create a 3D model through rapid prototyping e.g.
3D printing, CMM used to be an option with accuracy
and precision but it is slow and costly. With the
advancement of 3d scanning technology which is
much more accurate, precised , fast and cost effective
rapid prototyping has now become more fast,
convenient and cost effective with a high level of
accuracy and precision.
