Nebula3D Services Private Limited

With the support of our experienced team of personnel, we have established ourselves as one of the premier names that offers impeccable Engineering Solutions.

We Nebula3D Services understands 3D scanning technologies and the value they add to a project. We have carefully developed the most experienced and accomplished team to evaluate the application and use of this technology. Most importantly, we have been doing this successfully for over ten years. We understand the complexity and uncertainty associated with both scanning technology and the deliverables required in today’s markets. We have worked in many different industries, and carefully listened to the leaders therein, to arrive at time and cost saving measures.

Nebula3d Services uses the best equipment. Our unique, ultra-precise systems perfectly capture 3D shapes – even in objects with complex geometries and free-form surfaces. We use the best, so you get the best. The lab employs numerous CMMs, vision systems, 3D scanners, and other inspection equipment.

However unique the project, we can make it happen. Nebula3D''''s Surveyor line of automated and portable scanning systems are ideal for 3D scanning applications involving inspection and reverse engineering of complex shaped parts of virtually any size, shape, color, or material.
Our process saves our clients money by making production time substantially faster. Our patented laser line-probe technology dramatically reduces scanning time and data collection.

Our Process:
1. Data Acquisition via 3D Scanning An object that is to be laser scanned is placed on the bed of the digitizer. Specialized software drives the laser probe above the surface of the object. The laser probe projects a line of laser light onto the surface while 2 sensor cameras continuously record the changing distance and shape of the laser line in three dimensions (XYZ) as it sweeps along the object.

2.Resulting Data
The shape of the object appears as millions of points called a “point cloud” on the computer monitor as the laser moves around capturing the entire surface shape of the object. The process is very fast, gathering up to 750,000 points per second and very precise (to ±.0005").

3.Modeling Choice Depends on Application
After the huge point cloud data files are created, they are registered and merged into one three-dimensional representation of the object and post-processed with various software packages suitable for a specific application.

4.Point Cloud Data for Inspection
If the data is to be used for inspection, the scanned object can be compared to the designer’s CAD nominal data. The result of this comparison process is delivered in the form of a “color map deviation report,” in PDF format, which pictorially describes the differences between the scan data and the CAD data.

5.CAD Model for Reverse Engineering
Laser scanning is the fastest, most accurate, and automated way to acquire 3D digital data for reverse engineering. Again, using specialized software, the point cloud data is used to create a 3D CAD model of the part’s geometry. The CAD model enables the precise reproduction of the scanned object, or the object can be modified in the CAD model to correct imperfections. Laser Design can provide a surface model or the more complex solid model, whichever results are needed for the application.
