Reverse engineering and 3D modelling and scanning

January 4, 2011 Tags: , , , , ,

We at Enventure technologies offer a range of reverse engineering services as part of our commitment to helping companies with their mechanical design problems.

However, while most people understand the concept of building a product from finished principles to recreate a classic mechanical design which, for example, is missing the original blueprints, they often don’t understand what this involves. The first thing to understand is that there is a much higher dependence on computer aided modelling and design (CAD CAM) services these days.

Reverse engineering involves measuring an object so it can be reproduced through 3D modelling. The modern way to do this is via 3D scanning. There are a number of 3D scanning technologies available, including Coordinate Measuring Machine (CMM) scanning, 3D laser scanning, computed tomography and structured light digitising.

Whichever device is used, the principle is the same. The scanner analyses a solid object, collecting data on its contours, dimensions, density and sometimes colour and texture. The relative 3D modelling system software then uses this data to build a digital 3D model.

3D scanners are used in entertainment, medical and environmental applications, as well as industrial design and prototype reverse engineering. They work by processing points on the solid object into a digital format such as a triangular mesh, NURBS (Non-uniform rational B-spline) graphics or a CAD model. This makes the data available for other CAD CAM services, such as CAD visualization.

Today, companies like us use the most advanced 3D laser scanning technology and system software to provide reverse engineering services for our clients.
