• Technology • Methods • Users • Communities • Robohand • Opportunities • Risks

PRINT YOUR LIFE - 3D DRUCKEN HEUTE UND MORGEN 26.06.2013

TECHNOLOGY

• First use cases: high-end industry • Fast method to generate prototypes • Rapid prototyping

Rapid tooling Rapid manufacturing

• Addition to traditional manufacturing methods (like drilling, milling, mold injection,…)

• New materials will add more use cases

Example: Thingiverse

ROBOHAND

• Complete Model of a simple prothesis downloadable

• Variable in size • Available for all 3D-printers • Assembly plan included

DIY Prothesis

ROBOHAND

• 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

DIY Prothesis

ROBOHAND

• Perfect example for collaborative design and decentralized manufacturing

• Influence of people without capital and huge fabrication facilities is growing

• Production is shifting

DIY Prothesis

CHANCES

• 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)

Industry, Innovators, Makers

RISKS

• 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
