ReForm: Integrating Physical and Digital Design through Bidirectional Fabrication
Download as PPTX, PDF0 likes249 views
The document discusses 'reform', a system that integrates physical and digital design through bidirectional fabrication, allowing for a flexible design process where changes in one domain influence the other. This system supports both additive and subtractive fabrication and enables users to dynamically alter objects using both digital and physical tools. Key features include synchronized models, history and version tracking, and capabilities like 3D scanning and augmented reality overlays.

- 2. ReForm provides a more flexible design process by combining physical and digital modeling.
- 4. The Concept Bi-directional Fabrication The Implementation ReForm
- 5. + Motivation The creation process is uni-directional: once an object is fabricated it is separated from its virtual model. • Ties users to virtual modeling tools. • Virtual design must be completed before fabrication. • Re-shaping the physical object no longer influences the digital model. http://www.computerweekly.com/feature/How-3D-printing-impacts-manufacturing
- 7. + Bidirectional Fabrication Users can flexibly move between working on the digital model and physical object.
- 8. + Bidirectional Fabrication: Advantages The right tool for the right job: Expressive manipulations using the physical object Precise/repetitive actions using digital tools Evolutionary Fabrication: Incremental addition/subtraction/modification of the object ‘On-the-fly’ validation and refinement of the style, size, and confirm each element is fit-for-purpose.
- 9. + Bidirectional Fabrication: Advantages PhysicalVersionTracking: Physical object is continually synchronised to the digital model, allowing undo, redo, and version tracking in the physical world.
- 10. + ReForm Additive and subtractive fabrication system. Reusable polymer clay which is extrudable, machinable, and sculptable. Implements the bi-directional fabrication concept.

- 15. + Digital Modeling: Global Operations (A) Global flatten (B) Scaling the object
- 16. + Digital Modeling: Selective Operations via Annotations (A) Extruding an annotated patch (B) Producing accurate holes (C) Patterning model features
- 18. + History andVersioning (A) Modifications to the physical object (B) Can be undone using the digital model (A) (B)

- 22. + Discussion What is the impact on the design process? How do we measure it? Does ReForm encourage different or better designs? How do we address the accuracy/time trade-off in physical creation?
- 23. + Summary Bi-directional fabrication entangles digital and physical objects so that updates to one always propagate to the other. ReForm implements this concept allowing us to demonstrate the novel and flexible design process.
