2 HOUSE KEEPING Signup for xTalk mailing list at Tweet with hashtag #MITxTalks with reflections and questions about today’s talk 2/3/20152

3 WHAT IS “MAKING?” THE MAKER CULTURE IS A CONTEMPORARY CULTURE OR SUBCULTURE REPRESENTING A TECHNOLOGY-BASED EXTENSION OF DIY CULTURE. TYPICAL INTERESTS ENJOYED BY THE MAKER CULTURE INCLUDE ENGINEERING-ORIENTED PURSUITS SUCH AS ELECTRONICS, ROBOTICS, 3-D PRINTING, AND THE USE OF CNC TOOLS, AS WELL AS MORE TRADITIONAL ACTIVITIES SUCH AS METALWORKING, WOODWORKING, AND TRADITIONAL ARTS AND CRAFTS. THE SUBCULTURE STRESSES NEW AND UNIQUE APPLICATIONS OF TECHNOLOGIES, AND ENCOURAGES INVENTION AND PROTOTYPING.[1] THERE IS A STRONG FOCUS ON USING AND LEARNING PRACTICAL SKILLS AND APPLYING THEM CREATIVELY. 32/3/2015

4 TODAY CRASH COURSE IN 3D FABRICATION – JONATHAN HUNT REAL EXAMPLES ALBAN COBI – MIT EDGERTON CENTER NADYA PEEK – MIT MEDIA LAB AARON RAMIREZ – MECHANICAL ENGINEERING NANCY OUYANG – MITRE QUESTIONS AND ANSWERS PANEL WITH TODAY’S SPEAKERS 42/3/2015

5 CRASH COURSE IN 3D FABRICATION AKA RAPID PROTOTYPING 52/3/2015

6 RAPID 3D FABRICATION TWO BASIC CLASSES OF MANUFACTURING ADDITIVE MANUFACTURING SUBTRACTIVE MANUFACTURING POPULAR TYPES OF RAPID 3D FABRICATION CNC MILLS LASER & WATER JET CUTTERS 3D PRINTING 62/3/2015

7 3D MODELING AND SLICING COMPUTER AIDED DESIGN – CAD SOFTWARE FREE EXAMPLES AUTODESK 123D DESIGN TINKERCAD MORE EXPENSIVE EXAMPLES SOLIDWORKS AUTODESK AUTOCAD 72/3/2015

8 MIT SOLIDWORKS LICENSE – NEW TODAY MIT HAS LICENSED SOLIDWORKS FOR ALL FACULTY, STAFF AND STUDENTS INCLUDES: SOLIDWORKS PREMIUM SIMULATION PREMIUM FLOW SIMULATION PLASTICS SIMULATION ELECTRICAL PROFESSIONAL SOLIDWORKS COMPOSER SEARCH ON “SOLIDWORKS” – STARTING TOMORROW 82/3/2015

9 3D PRINTING – 5 MAJOR TYPES STEREO LITHOGRAPHY (SLA) SELECTIVE LASER SINTERING (SLS) POWDER BED PRINTING MATERIAL JETTING FUSED DEPOSITION MODELING (FDM) 92/3/2015

10 STEREO LITHOGRAPHY (SLA) THE ORIGINAL 3D PRINTING TECHNOLOGY CREATED BY CHARLES W. HULL IN 1984 USES LIGHT TO CURE A LIQUID PHOTOSENSITIVE RESIN LAYER BY LAYER AVAILABLE AS DESKTOP MODELS SUCH AS FORM1+ FROM MIT STARTUP FORMLABS APPLICATIONS: VERY DETAILED PROTOTYPES (INCLUDING MEDICAL MODELS) & CASTING PATTERNS 102/3/2015

11 SELECTIVE LASER SINTERING (SLS) USES A HIGH POWER LASER TO SELECTIVELY FUSE (SINTER) MATERIALS (USUALLY POWDERS) TO GENERATE A SOLID 3D OBJECT USES THE UN-FUSED POWDER AS SUPPORTS FOR THE PRINT MATERIALS RANGE FROM POLYMERS LIKE NYLON TO METALS INCLUDING STEEL AND TITANIUM. APPLICATIONS: PROTOTYPES WITH INTER-OPERATING PARTS, CASTING PATTERNS, SMALL PRODUCTION RUNS 112/3/2015

12 POWDER BED PRINTING FIRST DEVELOPED AT MIT IN 1993 USES A BED OF POWDER AND A BINDER APPLIED USING INKJET PRINT HEADS TO FORM 3D OBJECTS COMMON POWDER: GYPSUM PLASTER COMMON BINDER: CYANOACRYLATE (COLORED) CAN PRINT OBJECTS IN FULL COLOR (USUALLY JUST THE OUTER FEW LAYERS) ALSO USES UN-BOUND POWDER TO SUPPORT DURING PRINT PROCESS APPLICATIONS: PROTOTYPES WITH FULL COLOR, CASTING PATTERNS, AND MOLDS 122/3/2015

13 PERSONAL EXAMPLE OF POWDER BED PRINTING 132/3/2015

14 MATERIAL JETTING OR MULTIJET MODELING USE INKJET PRINT HEADS TO “JET” LIQUIDS THAT ARE THEN IMMEDIATELY HARDENED PHOTOPOLYMERS LIKE SLA USES OR WAX-LIKE MATERIALS THAT ARE SOLID ARE ROOM TEMP CAN APPLY MULTIPLE MATERIALS AT THE SAME TIME USING MULTIPLE PRINT HEADS REQUIRES SUPPORT STRUCTURES THAT ARE DISSOLVED OR MELTED AWAY APPLICATIONS: PROTOTYPES WITH INTER-OPERATING PARTS, CASTING PATTERNS, TOOLS FOR INJECTION MOLDING 142/3/2015

15 FUSED DEPOSITION MODELING (FDM) OR FUSED FILAMENT FABRICATION (FFF) PLASTIC FILAMENT (OR PELLETS) ARE MELTED DOWN AND EXTRUDED THROUGH A NOZZLE NOZZLE (AND/OR) BUILD PLATFORM MOVE TO PRINT EACH LAYER AVAILABLE AS DESKTOP PRINTERS SUCH AS MAKERBOT REP-RAP UTILIMAKER APPLICATIONS: FUNCTIONAL PROTOTYPES, SUPPORT PARTS, AND SMALL RUN PRODUCTION 152/3/2015

16 VIDEO OF FDM PRINTING 162/3/2015

17 ACCESS TO 3D PRINTING ON CAMPUS MANY LABS AND CENTERS HAVE 3D PRINTERS ONLINE SHAPEWAYS SCULPTEO MAKER SPACES NEARBY ARTISAN’S ASYLUM (SOMERVILLE) DANGER!AWESOME (CAMBRIDGE – CENTRAL SQUARE) EINSTEIN’S WORKSHOP (BURLINGTON) CAMBRIDGE HACKSPACE (CAMBRIDGE) 172/3/2015

18 3D PRINTING COVERS A WIDE ARRAY OF TECHNOLOGIES, CAPABILITIES & MATERIALS CREATES OBJECTS BY APPLYING LAYER UPON LAYER OF MATERIAL IS A TOOL IN RAPID PROTOTYPING IS OUT OF THIS WORLD 182/3/2015

19 3D PRINTING IS OUT OF THIS WORLD ISS Expedition 42 Commander Barry Wilmore holds a 3-D printed ratchet wrench 192/3/2015
