  2. 2. Agenda● Introduction● Overview over some tools● The workflow (Demo)● Q&A
  3. 3. Disclaimer1.This presentation is about the experiences I have made with 3D scanning in the past 6 month.2.It is meant as an entry point and a kickstart for persons who want to start 3D scanning without big costs.3.It doesnt cover the technical details but focusses on the practical aspects.4.To get a more in-depth view on the different methods and techniques, see for instance: 1. http://www.slideshare.net/dlanman/build-your-own-3d-scanner-introduction 2. http://en.wikipedia.org/wiki/3D_scanner

About me and my company: 89grad● Living in Berne (Switzerland)● 1y old daughter● Professional background: ● Communication Systems at EPFL ● R&D group of Swisscom ● Creation of own startup company in 2010● Hobbies: Sports, Tinkering, Photography, IT● 89grad ● Innovation & Prototyping ● (Mini-)FabLab Bern
  6. 6. Why would you want to 3D-scan an object?● As soon as you have a 3D printer, one of your new hobbies will consist in collecting (and printing, of course!) 3D models.● You can draw the models yourself (any CAD), program them (e.g. OpenSCAD), download them (e.g. thingiverse.com) and so on...● But sometimes, you would simply like to have a copy of that physical object in front of you.
  7. 7. How I got into 3D printing...● I was playing around with some tools, but nothing seriously. And dropped the subject.● A client called to have a toy figure printed out.● But: He did not really have the 3D model. He wanted to be the model itself...

  19. 19. The 3D scanning workflow is pretty straightforward.● Get the model you want to scan. ● Obvious.● Scan it. ● See two possible ways in a few seconds...● Clean it up (might take several iterations). ● Might take quite some time, depending on how you created the model.● Use it. ● :-)

  23. 23. Many tools can be used to clean-up the models and further process them...● MeshLab: Viewing and editing many 3D file formats.● MeshMixer: Creating 3D Mash-ups● NetFabb: Cleaning 3D ModelsA useful primer on cleaning:http://vimeo.com/38764290
