Introduction3:12
This video gives an introduction to the lecture series on "the role of materials in 3D printing/additive manufacturing". It highlights the topics to be treated and practical benefits of following the lecture series.
Lecture 1 - The nature of Materials4:42
Explore how material science underpins additive manufacturing and 3d printing, from atomic bonds and states of matter to how metals, polymers, and ceramics are laid down or fused.
Lecture 2 - The attributes of 3D printable Materials9:17
Lecture 3 - Phase change: most key materials phenomena in additive manufacturing10:34
Explore how temperature profiles govern phase change in three major additive manufacturing technologies such as stereolithography, fused filament fabrication, and selective laser melting, affecting curing, cooling, and microstructure.
Lecture 4 - Thermoplastics in Additive Manufacturing13:31
Explore thermoplastics in additive manufacturing, focusing on processing, material classes, cooling and crystallinity, and how bonding influences print quality. Learn strategies to control parameters and reduce cracks.
Lecture 5 - Some key process parameters in 3D print of thermoplastic materials5:50
Bonus Lecture1:50
Explore role of materials in additive manufacturing and use assessment tools to gauge your know-how across processing, technologies, economics, and design rules, then connect with hiring managers to identify roles.

Requirements

Basic chemistry, basic physics, materials science
An appreciation for how simple machines work
Able to process the relationship between temperature and matter

Description

This course draws the physical association between 3D printing and materials. It defines the nature of different kinds of materials as well as the attributes which makes them 3D printable. The role of phase transformation especially temperature driven transformation in 3D printed materials is treated at the fundamental level. This course presents a lot of research based instances of material behaviour under 3D printing conditions. Practice based data are also presented to reinforce the importance of materials know-how at the industrial level.

Who this course is for:

Second year engineering and science students, practice based engineers and technicians involved with materials processing (milling, injection moulding, casting etc)
Those considering a career in industry
Young engineers seeking insight to how materials are processed using 3D printing technologies
