3D scanning processes by contact and non-contact digitizers (theory and practical applications).
Processing of 3D scanned data e 3D modelling from scanned data.
3D model preparation for 3D printing.
3D printing processes by means of FDM and SLS technologies (theory and practical applications).
No reference books are available for the subjects of the course.
Support material consists of a set of slides used by the teacher during the lessons. Students will be provided with such material by means of the moodle platform.
Learning Objectives
The aim of the course is to provide the students with practical knowledge to: manage and operate 3D scanners, reconstruct 3D CAD models from scanned data, manage and operate 3D printers. Particular attention will be devoted to the application of these skills to product re-enginering, dimensional control, optimal choice of 3D printing parameters.
Prerequisites
none
Teaching Methods
In the first part of the course students will be briefly introduced to theoretical background of 3D scanning techniques and equipment. Afterwards, students will have to practice with hardware and software equipment for 3D scanning and CAD reconstruction by using laboratory equipment.
In the second part of the course students will be briefly introduced to theoretical background of 3D printing techniques and equipment. Afterwards, students will have to practice with hardware and software equipment for 3D model preparation and 3D printing by using laboratory equipment.
In the third part of the course students will choose a practical case study and will be followed by the teacher while they apply to it their skills and laboratory equipment.
