3D Printing & 3D Scanning | Additive Manufacturing Fundamentals | Fab Academy. Adrian Bowyer

In this Fab Academy session, students explore the powerful world of 3D scanning and additive manufacturing, learning how to capture physical objects digitally and transform digital models into complex physical forms.

Led by Adrian Bowyer and Ohad Meyuhas, this class covers both the theory and practice behind modern 3D fabrication technologies.

🔎 Introduction to 3D Scanning

Discover how 3D scanners work and the science behind them:

Structured light scanning

Stereo vision systems

Point correspondence & surface reconstruction

Limitations and accuracy challenges

Practical scanning demonstrations

Understanding scanning techniques helps bridge the gap between physical objects and digital models.

🖨️ 3D Printing Principles & Applications

Learn how additive manufacturing differs from subtractive processes like CNC machining.

✔ Advantages:

Low mechanical forces

Complex geometry fabrication

Reduced material waste

⚠ Challenges:

Print failures (e.g., “bird’s nesting”)

Material emissions

Speed vs. quality trade-offs

The session covers key technologies including:

FFF (Fused Filament Fabrication)

SLA (Stereolithography)

Vat polymerization methods

🛠 Design Rules & Advanced Techniques

Students explore:

Overhangs and bridging

Anisotropic strength in printed parts

Support structures and adhesion techniques

Multi-material and multi-color printing

Internal reinforcement strategies

Conveyor-belt 3D printers for continuous production

The weekly assignment challenges students to design and print an object that cannot be made subtractively, leveraging the true advantages of additive manufacturing.

🚀 3D printing isn’t just about making objects — it’s about rethinking how things are designed and produced.
