Abstract

3D printing is a rapidly growing field of science. Despite the fact that the basic principles of printing were developed as early as 1981, and the first printer was patent in 1986 [1,2], a very rapid development of this method has been observed for several years. 3D printing allows you to make elements using different methods and different materials. Starting with paper (LOM), through polymers (FDM, SLA) and ending with metals (SLS, SLM). The combination of 3D printing and 3D scanning allows to made very quick dedicated elements for a specific application. For example, thanks to combine this two methods, we can make comfortable prostheses and orthoses - fit to the owner's body. Nowadays, thanks to use of cameras in mobile phones, which already have a relatively high resolution, it is possible to model 3D objects without the need to use expensive equipment.

The classes will show how to create a customized product using free computer software. In this case, it will be making a face mask based on a 3D scan of the head. It will be shown two different ways of making such a mask. The first way will be based on the use of ready-made elements and will be entirely created in Blender[3] software. The second way will be shown by using Meshmixer [4] and 3D Bilder [5]. In this case, the mask will require more work, but will be more modifiable. In addition, the classes will show the modern application of 3D scans and 3D printing in bioengineering and other areas of modern technology.

In the second part of the class you will apply the learned skills to your assignment and creat a part needed to define your prototype.

Skills you will acquire

  • Technology overview
  • Basic 3d modeling skills

Software

We ask all the students to install the following software prior to the training on their local computers to actively participate in the training.
