Role of Reverse Engineering and 3D Laser Scanning in Part Duplication

Reverse Engineering word was originally coined from the practice of skilfully emulating complex design and prototypes of competitors products. 

Reverse engineering techniques helps the developer to reduce time to market for the component and find out possible improvement. It also reduces the time spent in designing, testing and optimizing component with economy.

Reverse engineering is now considered legal activity with new technology like Laser Scanning Services and 3D digitizing. 

CAD Reverse engineering is helpful for companies who want to reduce errors generated previously due to faulty applications. With reverse engineering, one can optimize components easily and speedily.

In this process firstly the technician fragments each and every component of the assembly. He then scans individual part or component using contact or non-contact article inspection methods. 

This 3D scans are then converted into 3D models using Solidworks or Pro-Engineer software with 100% accuracy for further applications. Sometimes you need manufacturing analysis for optimization and developing prototypes.

It is also important to note that product or part reverse engineering services have it own risks and challenges. You may lend in trouble if the design is patented and you have no legal rights to use or modify the design without written permission and necessary approvals.

The class apart technology - 3D laser scanning

To construct a three dimensional digital models, 3D laser scanning is employed. A 3D laser scanner is a device that analyzes a real-world object or environment to collect data on its shape and possibly its appearance. 

The so collected data is hence utilized for the 3D models. In the present scenario of technical advancements, the horizon of its applications is expanding day by day.

The 3D Laser Scanning technology use different mechanism for different surfaces. For flat profile shapes or simple convex curved surfaces a carriage system is used which has rigid arms held tightly in perpendicular relationship and each axis glides along a track.

For probing into crevasses and interior spaces with a small mouth opening an articulated arm with rigid bones and high precision angular sensors is employed. 

A combination of both methods is used, like an articulated arm suspended from a traveling carriage, for mapping bigger objects with interior cavities or overlapping surfaces.

3D laser scanning could benefit the design process in following ways:

• It increases effectiveness working with complex parts and shapes.
• It helps with design of products to accommodate someone else's part.
• If CAD models are outdated, a 3D scan will provide an updated version.
• Replacement of missing or older parts can be done.

It has influenced a number of sectors and has gained immense popularity setting apart other similar technologies.

Some of the areas where 3D laser scanning is heavily used are:

• Apparel industry for wearable technology, protective wearing, thermal comfort, athletic or uniform equipment and mass customization.
• Biomedical sector for obesity determination, rehabilitative engineering and body asymmetries.
• Reverse engineering for standards or tolerance, FEA simulation and rapid prototyping.
• Ergonomics for verification of models and seat design.
• Construction industry and civil engineering.
• Entertainment industry.
• Material processing and production.
