Mo m present_friday_3d printing for circular economy and open hardware labs

  1. 1. 3D printing & openware labs 3D printing from Circular Economy to Open Source Labs This project has received funding from the European Union's Erasmus + Programme for Education under KA2 grant 2014-1-IT02-KA201-003604.

  2. 2. 3D printing & openware labs • ABS - not biodegradable , stinks! • PLA – natural & biodegradable (from mais) • PVA hydrosoluble support • TPU (like PA flex….) • PETG • Policarbonato … NEW Materials for 3D filament Nylon Carbon Recycled paper on an hydrosoluble Matrix recyclable Parts glued together by water wetting Politecnico di Milano- spin off 3Dpaper Mixed with mineral powders to simulate architectural materials such as clay, gypsum, stone, brick etc… Architectural Metals
  3. 3. 3D printing & openware labs It’s an Open World ! Knowledge is the only thing that grows when you share it! • -open access e-prints (20 years) (Ex. Physics -> Education) • Opensoftware Linux, Ubuntu, LibreOffice,Tracker, … • Open Educational Resources OER ARTICLES,IDEAS,Software OpendesignforScientific Hardware • Open hardware Arduino, makers etc… • Open Labs 3 D printing+ Arduino,RepRap ( • Citizen Science: airduino,…
  4. 4. 3D printing & openware labs 1 Open source developement is • Decentralized • Transparent • Participatory • No need to reinvent the wheel • More people collaborate to solve problems. Users as a group are smarter than any one individual • Students collaborate in knowledge building- a world wide community • Service Learning Commercial approach is • Top down • Black box • Secretive Why should we pursue open source @school
  5. 5. 3D printing & openware labs Lab equipment Plastic ShredderFilament extrusion stampa3D "The future belongs to those who believe in the beauty of their dreams." E. Roosvelt 1.

  6. 6. 3D printing & openware labs Makers@School Project- mainly Primary school Free download at International Centre for Theoretical Physics Trieste Italy Focus: Developing World, Education Open-source hardware for reasearch and education- Joshua M.Pearce Physics today November 2013 pag.8
  7. 7. 3D printing & openware labs 1
  8. 8. 3D printing & openware labs Open Source Lab: Astronomy : PiKon Telescope Even MORE low cost To fit
  9. 9. 3D printing & openware labs 1 Open Source Lab: Physics Battery holder Lab jack Anemometer Rain meter Automated filter wheel changer Laser alignment base Laser support Optical rail components Ultra low cost optical rail: drawer sliding guide
  10. 10. 3D printing & openware labs 1 Centrifuge Biropette: high precision pipette. Open Source Lab: Biology/Chemistry Test tube holders Customized funnels Magnetic stirrer Water testing platform Molecular models
  11. 11. 3D printing & openware labs Open repositories - THINGIVERSE Thingiverse maintains an application allowing OpenSCAD scripts to be easily manipulated. You don’t even needOpenSCAD Input: geometric specifications quick customizations from anyone Free download - files of printable objects Open source optics library /open-source-optics Fiber optic cable holders, automated filter wheel changers, lens holders, lasr holder,jack lab etc… 500$ VS 15000$-30 groups CHEAP extreme prices for educational equipment CUSTOMIZABLE Accelerate availability of open source scientific equipment for anyone Gasket Just input • Thickness • Inner radius • Outer radius
  12. 12. 3D printing & openware labs 1 OpenSCAD • free software available for Linux/UNIX, MS Windows and Mac OS X. • You don’t need to know CAD • One of the primary benefits of OpenSCAD is the ability to design customizable content. • These are designs which are parametrized using parameters or top-level variables. OpenSCAD DOCUMENTATION Open Wiki Book (instantly updated and improved) /OpenSCAD_User_Manual/ Kindle When you share an OpenSCAD design on Thingiverse, you can have the web site customize your OpenSCAD file based on user input. Williams, Al. OpenSCAD for 3D Printing (p.57). Unknown. Edizione del Kindle. Plenty of software • Blender free • Sketchup free (Pro version pay) • Rhino 1000 euro/500 educational • Tinker cad free • Inventor, Solidworks, PTC
  13. 13. 3D printing & openware labs 1 The trick is use variables with special comments. Here’s the mending plate file: /* Really simple "mending plate" with two #6 holes -- I use this to clamp a GT2 belt, but it probably could be used for anything. Al Williams, April 2013 */ // Length of plate (mm) length=17; // [10:100] // Width of plate (mm) width=6; // [5:100] // Thickness of plate (mm) thickness=3; // [.5:20] Williams, Al. OpenSCAD for 3D Printing (p.57). Unknown. Edizione del Kindle. In brackets the range of choices ; if the range has a colon, it turns into a slider Separated by commas -->dropdownbox No range at all-> input box
