Learning about Rapid Prototyping

Open Source Software and Approaches

Rapid Prototyping

Computer Aided Design (CAD) Computer controlled tools

Computer Aided Manufacturing (CAM)

Designs are made and tested quickly Designers have control of the manufacturing

Learning Rapid Prototyping

Fab Labs Worldwide network of labs MIT Sponsored Boston – South End Technology Center Providence – AS220

MakerSpaces / HackerSpaces Worldwide movement Sprout – Thursday project night Artisans' Asylum – Class structure

Design Process

“Your first try will be wrong. Budget and time for it” Aza Raskin

Nothing comes out right the first time

It may take several attempts until it comes out right

This takes patience

Design Process

Rapid Prototyping allows Design Spiraling Cycle through the Engineering Design

Process Loop over and over Refine the design through multiple iterations

Student Control of Manufacturing

In classroom design In classroom manufacturing Custom design Designs are repeatable

Make and Refine a Design

Design Manufacture Test Improve Repeat until the design is great

Production Run Design

Develop one design Improve it Remove flaws Create working prototype Develop a plan for production run

Make a Production Run

Carry out your Production Plan Use your prototype as a production model

Make 5 copies Make 20 copies Make 100 copies Make 1000 copies

What would you do with this many products?

Rapid Prototyping and Design

Quick to get started Models are precise Models are repeatable Models are adjustable Models are refinable

Rapid Prototyping and Design

Quick to get started Make your design Fabricate it Test it Improve it Design for an audience of one is possible

Rapid Prototyping and Design

Models are precise Extremely accurate tools 1/1000 th of an inch Materials can affect precision

Rapid Prototyping and Design

Models are repeatable Use the same design over and over Make production runs Do distributed manufacturing Files are easily shared

Rapid Prototyping and Design

Models are adjustable Start with a basic design Fabricate it Test, revise, improve Cycle through the Engineering Design

Process Design/Make until it works/assembles properly

Rapid Prototyping and Design

Models are refinable Designs can be developed in low cost material Produce in more expensive material Change color, durability, texture Designs can be customized in production

Sharing and Collaboration

Important 21st Century Skills

Students live in a world of shared information

Sharing does not have to be cheating!

Sharing and Open Source

Open Source enables sharing Info about designs are available to all Designers can get started quickly Legacy of information Results and designs must be shared

Who is using Open Source?

Google - Chrome, Android Mozilla - Firefox Arduino microcontrollers Makerbot 3D printers

You and your students use Open Source daily

Sharing and Documentation
