9. ROBOHAND
DIY Prothesis
• Complete Model of a simple
prothesis downloadable
• Variable in size
• Available for all 3D-printers
• Assembly plan included

10. ROBOHAND
DIY Prothesis
• Print time: 4 hours per set
• Print cost: approx. 4€
• Great opportunity to help,
donate and change things
• 25.000 MakerBot printers
could easily print 25.000
ROBOHANDS daily

11. ROBOHAND
DIY Prothesis
• Perfect example for
collaborative design and
decentralized
manufacturing
• Influence of people without
capital and huge fabrication
facilities is growing
• Production is shifting

12. CHANCES
Industry, Innovators, Makers
•
•
•
•
•
•
Low cost and investment
Reduction of energy and material demand
Almost unlimted availablility (everywhere/always)
Small installation and training effort
Simple Handling
Small environmental foot print
(biogradeable material, less transportation, storage and noise)

13. RISKS
Industry, Innovators, Makers
•
•
•
•
•
•
Quality and regulations (TÜV, CE, …)
Piracy, Copyright abuse
Competition between companies and individuals
Overestimation of hypes and trends
Underestimation of material cost and neccessary skills
Wrong estimate of breakeven points
