LESSON 1.5: RE (Reverse Engineering)
At the end of the training, you will know:
1. the main types of 3D scanners: contact or non-contact.
2. how to scan an object.
3. the steps necessary to create a digital model that includes volume, texture, and color of a real object by 3D scanning.
4. the preparation of the object for scanning: surface treatment and positioning of the reference points.
5. the post-processing phase: processing of the point cloud to increase the accuracy of the acquisition, triangulation process, formation of a polygonal mesh to obtain the CAD model.
LESSON 1.4: CAM (Computer Aided Manufacturing)
The CAM, acronym for Computer-Aided Manufacturing, refers to
a category of software products that allow you to generate the instructions
needed for a Computer Numerical Control (CNC) machine tool to follow a toolpath
and create a certain part starting from a CAD project.
Once the design phase of a product has been completed, to go ahead with its construction, it is necessary to extract the idealized forms from raw material. To do this you can use manual machines controlled by skilled labor, or machines equipped with CAM software.
The main objective of
the CAM lesson is to obtain the instructions needed for a CNC machine tool to
follow a toolpath and create a certain part starting from a CAD project.
LESSON 1.3: CAD (Computer Aided Design)
CAD, or Computer-Aided Design and Drafting (CADD), is the technology that allows you to design and then create the related technical documentation, replacing manual drawing with an automated process.
This lesson provides the tools necessary to create the geometry of 2D sketches and, from these, the tools to create 3D models for 3D printing.
LESSON 1.2: CAE (Computer Aided Engineering)
The main objective of the CAE lesson is to predict the behavior of a component subjected to external loads through finite element analysis.
CAE technology allows performing linear, non-linear, thermal, stress, and dynamic analyzes, studying geometry and physical properties, to simulate product performance.
The lesson on CAE provides the student with the tools necessary to understand and create different types of analysis: static, thermal, peak load, and modal.
LESSON 1.1: WHY USE CAE, CAD, CAM, RE?
This lesson explains why CAE, CAD, CAM and RE technologies are necessary for the design of an object.
For the realization of a part it is possible to choose between two manufacturing possibilities: additive manufacturing technologies also called Additive Manufacturing (AM) or subtractive production. Additive manufacturing involves the addition of layers of material to create an object, whereas subtractive production removes material from an object.
Thanks to this lesson, you begin to understand which technology is most suitable to use to create a 3D object with a 3D printer.
