MicroScribe Portable CMMs

Combining functionality with affordability

I’ve been using a MicroScribe to collect 3D data on fossil human bones for over 15 years. I’ve used it in collections all over the world, and it has become an indispensable tool for analyzing the anatomy of our ancestors.

Functionality and Affordability

MicroScribe in action

CMMs were developed to capture geometric characteristics of objects as early as the 1950’s and has since become an industry standard for 3D measurement technology. MicroScribe is a portable CMM that combines the functionality of high-end CMMs with affordability in mind. While traditional CMMs can be big and expensive, MicroScribe is an cost-effective measurement tool used for reverse engineering projects, inspection of manufactured parts, and scientific measurements worldwide.

Introducing MicroScribe i+ Series

MicroScribe i portable cmm

The MicroScribe i+ series of portable CMMs can be used for a wide range of modeling and data capturing applications. It comes in two models: 1) i+ has a reach of 25 inches 2) iL+ has a reach of 33 inches. Simply trace over the contours of an object to build complex 3D and 4D datasets.
