OUTLINE • Current Mass Production Manufacturing Practice • Rapid Prototyping • Fab Labs: • Capabilities • Structure • Current status • Business Incubation – IDEA PLATFORM • The Future? • Printable electronics • DNA computing • ….?
CNC Machining • Computer Numerical Controlled machining • Refers specifically to the control of a machine for fabrication of materials into shapes using instructions executed via a computer programme called G-code
Rapid Prototyping using CNC machines Three basic types: • Subtractive • Additive • Equality
Rapid Prototyping: Subtractive • SUBTRACTION: How can you make a sculpture of a giraffe from a block of wood? Chip away everything that doesn’t look like a giraffe. • Advantages - speed
Rapid Prototyping: Subtractive • Example: Milling machines from Roland DG
Rapid Prototyping - Additive • ADDITION: Conversely, one can create a sculpture of the giraffe using clay by adding anatomically-accurate bits of clays to other anatomically-accurate bits of clays, producing an anatomically-accurate whole. • Advantages: • Intricate internal detail
Rapid Prototyping: Additive • Virtual designs created using CAD • Transforms them into cross sections, • Creates each cross section in physical space, one after the next until the model is finished. • WYSIWYG • LIMITATION: S-L-….O-W
Mass Production vs Rapid Prototyping • Additive processes are very slow – hours to days per item • Subtractive processes can achieve economically viable times
MIT’s Fab Labs • Fab Labs – Fabrication Laboratories or even “fabulous” laboratories • Born out of class: “How to Make (Almost) Anything”. Neil Gershenfeld, MIT Media Lab • Collection of RP machines with high capabilities
MIT’s Fab Labs • The Tower System - Bakhtiar Mikhak and the Grass Roots Invention Group at the MIT Media Lab
The MIT Tower System It is used for: • 2D and 3D mechanical design and modeling, • simulations, • data analysis, • design of various electronic and computational devices, • designing and laying out printed circuit boards, • programming, • interfacing with the fabrication tools, • internet access for communication and information retrieval purposes, and • documentation.
MIT’s Fab Labs – products? • bicycle • proximity warning device • diary security device • Scream absorber • milk tester, • diesel engine timing device • …
MIT’s Fab Labs – Status? Lyngen Alps, Norway Cartago, Costa Rica Pabal, India Boston, USA Takoradi, Ghana Pretoria, S. Africa Soshanguve, S. Afric
MIT’s Fab Labs – Potential? • Ultimately, these machines can replicate themselves.
MIT’s Fab Labs – Limitations? • Maximising potential – adequate understanding of and training on equipment • Materials from which to make things
IDEA PLATFORMInnovative Development for Emerging Africa A local business incubator OBJECTIVES • People based – people targeted • Technology for utility • Understanding stuff – nuts and bolts to the ephemeral
Business Incubation • Is an economic development organization designed to accelerate the growth and success of entrepreneurial companies through an array of business support resources and services that could include physical space, capital, coaching, common services, and networking connections.
Business Incubation in Kenya • JKUAT’s Center for Business Innovation (JKUAT-CBI), which has received US$100,000 seed money from InfoDev • ICTpark.com Incubator • Kenya Country Business Incubator (KeKoBI) Secretariat, and • the Africa Region Business Incubator Association, formed in Pretoria, South Africa in April 2005. • University of Nairobi, Back-office Business (BoB) - School of Computing and Informatics: intended for offsite delivery of a range of non-core service functions to companies worldwide. It is currently being established. • Centurion Systems
IDEA PLATFORM • Fab Lab set up – access by students • Ideas promoted into IDEA PLATFORM • Provide incubatees with assistance with: • ethnographic surveys • Business plan writing • Legal issues • tech development • Housing • Admin assistance • Source funding – FFF (family, friends and fools), VC, angel funds, micro-credit, banks, govt…. • IDEA PLATFORM will partner with incubatees so as to ensure sustainability of incubator
