Overview

The course aims at providing knowledge on additive manufacturing (AM) technologies, which are receiving increasing interest in industry and are being described as the third industrial revolution. Competence in this field is fundamental for the soon-to-be engineers who want to stay current with innovation and gain a portable career credential.

Course contents

INTRODUCTION TO AM [0.5 ECTS]
Basic concepts of additive manufacturing, from prototypes to finished parts, evolution of AM definitions.
AM cycle: from the STL to the finished product.
Design for Additive Manufacturing.
Applications: models, automotive, aerospace, defense, consumer, medical and prosthetic dispositive, art and fashion, mechanical, architecture.
Use of AM in the production of equipment for polymeric materials.
Use of AM in metal casting.
Economic and logistical evaluations.
Impact of AM in business.
Development of AM: lines of research.

AM TECHNIQUES [3.5 ECTS]
ASTM Classification, reference standard, technical committee F42.
Process, machinery, materials, post-processing and finishing, properties and use, of the following AM techniques are studied:
- Binder jetting
- Vat photopolymerization: SLA and DLP
- Material extrusion
- Material jetting
- Directed energy deposition
- Powder bed fusion: laser techniques for polymers (LB-PBF/P) and metals (LB-PBF/M), electron beam tecnique (EBM), Multi Jet Fusion for polymers and metals.
Moreover, for Powder Bed Fusion of metals: powder and part characterization, industrial machine and powder management, safety.

SOFTWARE PRACTICES [2 ECTS]
Use of Materialise Magics for the build job preparation on a LB-PBF/M machine. Practical lectures will deal with all the phases needed to prepare a part, from the CAD file to the final part.

Teaching methods

Lectures, laboratory exercises, individual and group projects, multimedia materials. Seminars by international experts and companies. Attendance is optional but strongly recommended for laboratories.

Assessment methods

The evaluation includes a practical exam with the software that is worth 10 points. The remanining 20 points are given on the oral exam, which can cover any topic within the course contents.

Learning outcomes

Participants will learn the fundamentals of AM of polymers, metals, composites, and biomaterials; process capabilities in terms of buildrate, cost, quality of the product and their relation to material characteristics, process parameters, and machine designs.
They will be able to select an AM technique according to the requirements of the final part, and suggesting modifications to the geometry to comply with design for AM restictions.
The student will be able to proficiently use Materialise Magics for the industrialization of parts for the LB-PBF processes.
