Week 5 3D Laser Scanning, Modeling, Processing images and Cutting materials

Demonstration of three-demensional laser scanning techniques with application in engineering practice

Conversion on 3D scanned object in CAD format

Comparison on scanned 3D object with CAD model

This week we learn how to do a 3D scanning and editing these models. Also how to work on the scanned arm and cut it in the Fusion 360 °. With the software 3D scans can be edited and 3D printing can be performed. In addition, objects are also designed. A volunteer of our group was so friendly to scan his arm that we could work on it.

After scanning the arm we were shown how to modify the scan. The addition of the Fusion 360 ° Eagle and Meshmixer programs help to create the right format. So we could convert the file with Meshmixer.

Through the various programs we could change the representation of the models by using different constructions and modifying them in different ways. Importing a model is easy. Simply open Mashmixer and click on Import and select the uploaded file. In our case, the arm.

To zoom in and out, you can use the mouse scroll button and right-click to move the model. Transformation of the model After loading the 3D model, we can edit it. It is important if you want to print the model it ideally as flat as possible on the building board and minimal overhangs are available.

The further processing also takes place in Fusion 360 ° around the arm, a Cyliner must be fixed as close to the arm.

To cut the arm, a line must be pulled through the arm. This line will later be re-selected as a tool to divide the arm. For example, with this method a splint can be made exactly for one arm. This requires something as a fixation or support for weakening the muscles or disabilities.
