JargonComputer Aided Design (CAD)Computer Aided Manufacturing (CAM)Computer Numerical Control (CNC)Material Safety Data Sheet (MSDS)

Personal manufacturing,aka., 3D printingAdditive and subtractive manufacturingPhotopolymer based printingPowder based printingFilament based printing

Types of filamentABS (Acrylonitrile Butadiene Styrene) plastic Very stable and safe (Lego plastic) High melting temperature SturdyPLA (Polylactic acid) plastic Biodegradable Safer than ABS for food & body use Low melting temperature Somewhat fragile

Types of filamentPVA (Polyvinyl alcohol) plastic Dissolves in cold water Used for support in complex modelsWood plastic Darkens with higher extruder temperatureBrick plastic Has the texture of sandstone

Types of filamentTaulman 618 Nylon Very sturdy, flexible and stable Toxic fumes while printing; needs aventilation hood or equivalentTaulman T-Glase Very sturdy, similar to acrylic Translucent No fume issues

Types of filamentUrethane (Polyurethanes) Flexible rubber Toxic fumes while printing; needs aventilation hood or equivalentRecreus Filaflex Elastic plastic Suitable for printing shoes May require a special extruder

Types of filamentConductive ABS Blend of ABS and carbon fiber Can print both electric circuits andelectromagnetic shieldingFlame Retardant ABS Self extinguishes Suitable for appliance parts (like coffeemakers)

Established Uses Product prototypingSimple home repairToysJewelryHearing aidesStop motion animationModels for pre-surgery planningArchitectural modelsWorks of artDecor

New Uses Nike shoe cleat for the NFLTissue samples for drug testingPlastic bones for reconstructive surgery2,000 sq ft house frames in 24 hours for 5kProsthetic hands for 60Waterproof casts with better air circulationDIY cosmeticsOmnidirectional speakersFax 3D objectsDuplicating fossil records

Social Impact Education Do It Yourself and Fix It Yourself Home: Best Buy, MakertronicCommunity: Fayetteville, Sacramento, SaginawArt: Captured Dimensions, 900lbs of CreativeBusiness: PartSnap, The UPS Store

Thinking About the FutureRemember dot matrix printers and fax machinesin 1974? Computers and printers have come along way in 40 years, personal manufacturing isjust beginning.Plan to upgrade every 2 years to stay current orevery 5 years to stay functional.
