A Revolution Called 3D Printing

3D printing or Additive Manufacturing takes digital input in the form of Computer Aided Design (CAD) model and creates solid, three dimensional parts through an additive, layer by layer process.

14

Concept Modeling 15Use:Small firms testing out more ideas and developing only the right projects.

Large companies, concept modeling within departments.

Example:Architectural models. Small scale models.

15

Functional Prototyping Use: Creating realistic prototypes.

Look and feel of a real product.

Example: Lamborghini Aventador.

Build a functional prototype of the car.16

Use:Building durable, stable, and repeatable parts.

accuracy can be compared with injection molding.

Example:Kelly Manufacturing Company (KMC).Otherwise takes an estimated 3-4 weeks.17End use parts

Intriguing Applications18

19

Artificial Arms for Disabled20Medical

Richard Van As, a South African carpenter, assembles a Robohand and fits it to Liam Dippenaar. Liam was born without fingers on his right hand. MakerBot provided them with the 3D printing technology that they used to print the parts for the Robohand. 20

Secrets of the Heart21Medical

Laura Olivieri, a pediatric cardiologist at the Children's National Medical Center in Washington DC, says that these replica hearts are ideal for dry runs of complex operations, allowing the surgeon to see beforehand the exact anatomical landscape they will have to navigate.

21

Grow Your Own Organs22Medical

Surgeon Dr. Anthony Atala demonstrated during TED an early-stage experiment that could someday solve the organ-donor problem: a 3D printer that uses living cells to print out a transplantable kidney. 22

Print @ Home23

Do It Yourself

Microsoft provides support for 3D printers in its Windows 8 & 10 operating systems.

Developed an automatically-loading driver software that will ease 3D printer set-up at home.23

Pottery24Do It Yourself

The Electronic Artisan is made of a 3D laser scanner and 3D printer. Virtual artisanship is made possible by the use of software that tracks hand movement and printing methods that mimic age-old techniques.24

25

26RepRap ProjectDo It Yourself

The RepRap project started as a British initiative in 2005 to develop a 3D FDM printer that can print most of its own components, but it is now made up of thousands of collaborators world wide.From open source 3D printers to open source materials and open source models.

Thats Sweet!27Food

Los Angeles architects Kyle and Liz von Hasseln have set up a business that produces 3D-printed sugar sculptures for wedding cakes, table centerpieces and pie toppings.

This way 3D printing transforms sugar into a structural and sculptural medium. In future, it can define the form of the food instead of the food defining the structure. 27
