Inside3DPrinting_AdamCohen Presentation Transcript

  • 1. © 2014 Additive Insight LLC, www.additiveinsight.com 3D PRINTING, PAST AND FUTURE Inside 3D Printing Conference and Expo, NYC, April 3, 2014 Adam Cohen, Principal Consultant and CEO Additive Insight LLC www.additiveinsight.com adam@additiveinsight.com
  • 2. © 2014 Additive Insight LLC, www.additiveinsight.com THE PAST
  • 3. © 2014 Additive Insight LLC, www.additiveinsight.com Not Quite an Overnight Sensation • 3D printing was first commercialized nearly 30 years ago • With just one process • The industry has grown very steadily since • More applications • More processes • More materials • More companies • More revenues • We now have a $3B industry and an major ecosystem of machines, materials, services, software… • And even, consultants
  • 4. © 2014 Additive Insight LLC, www.additiveinsight.com STEREOLITHOGRAPHY
  • 5. © 2014 Additive Insight LLC, www.additiveinsight.com The Epicenter • Sylmar, CA: Best known for a major earthquake in 1971 • Economically, a far more significant “earthquake” was coming • In 1986, 3D Systems was founded, giving birth to an industry that will transform our lives
  • 6. © 2014 Additive Insight LLC, www.additiveinsight.com The Genesis of Stereolithography • Invented by Chuck Hull at Ultra Violet Products • Spun off into 3D Systems with Ray Freed’s seed funding • Initial prototype made with HP plotters, a mercury lamp, a fiber optic bundle, and masking tape
  • 7. © 2014 Additive Insight LLC, www.additiveinsight.com Just a Bit Too Wild • Ray and Chuck couldn’t find investors at first • Eventually sold 70% of the company to a Vancouver firm and went public in Vancouver
  • 8. © 2014 Additive Insight LLC, www.additiveinsight.com Famous at Last
  • 9. © 2014 Additive Insight LLC, www.additiveinsight.com A Single Paragraph That Changed my Life • By the time I joined in 1987, starting to ship 6 “Beta” machines to Kodak, Pratt & Whitney, and others
  • 10. © 2014 Additive Insight LLC, www.additiveinsight.com SLA-250: The Industry Workhorse • Introduced at the “AUTOFACT” show in November 1988 • 3D in 1989 • Sales grew from $4.6M to 17.5M • Staff grew from 94 to 194 • Key patent survived a legal challenge from DuPont • In 1990, 3D was listed on NASDAQ
  • 11. © 2014 Additive Insight LLC, www.additiveinsight.com Ads of the Day
  • 12. © 2014 Additive Insight LLC, www.additiveinsight.com Early Adopters
  • 13. © 2014 Additive Insight LLC, www.additiveinsight.com SELECTIVE LASER SINTERING
  • 14. © 2014 Additive Insight LLC, www.additiveinsight.com Selective Laser Sintering (SLS)
  • 15. © 2014 Additive Insight LLC, www.additiveinsight.com The Birth of SLS
  • 16. © 2014 Additive Insight LLC, www.additiveinsight.com DTM, then 3D Systems
  • 17. © 2014 Additive Insight LLC, www.additiveinsight.com FUSED DEPOSITION MODELING
  • 18. © 2014 Additive Insight LLC, www.additiveinsight.com Fused Deposition Modeling (FDM)
  • 19. © 2014 Additive Insight LLC, www.additiveinsight.com IBM’s Foray into 3D Printing • Similar to FDM • Unveiled in early 1994 • Ultimately left the business • Stratasys bought the patents
  • 20. © 2014 Additive Insight LLC, www.additiveinsight.com “3D PRINTING”
  • 21. © 2014 Additive Insight LLC, www.additiveinsight.com Powder, Binder, and a Great Name
  • 22. © 2014 Additive Insight LLC, www.additiveinsight.com Soligen and DSPC 1 jet 128 jets
  • 23. © 2014 Additive Insight LLC, www.additiveinsight.com Many, Many, Many Castings
  • 24. © 2014 Additive Insight LLC, www.additiveinsight.com Upload and Quote
  • 25. © 2014 Additive Insight LLC, www.additiveinsight.com Z Corp • License for concept models • Hired MIT grad students • First multi-color process
  • 26. © 2014 Additive Insight LLC, www.additiveinsight.com Multiple Fields of Use • Extrude Hone: Direct metal parts • Later: ExOne • Therics: Medical devices • Later: Defunct • Specific Surfaces: Ceramic filters for smokestacks • Later: Defunct
  • 27. © 2014 Additive Insight LLC, www.additiveinsight.com OTHER EARLY TECHNOLOGIES
  • 28. © 2014 Additive Insight LLC, www.additiveinsight.com • 1991-2000 • 375 machines sold • Benefits • Fast, especially for large parts • Big issues • Reliability, maintenance • Mechanical strength • Special paper • Time-consuming post-processing • Fire hazard • Might have survived had it focused on its key application Laminated Object Manufacturing (Helisys)
  • 29. © 2014 Additive Insight LLC, www.additiveinsight.com LOM
  • 30. © 2014 Additive Insight LLC, www.additiveinsight.com Not Quite Dead • Kira • Selective gluing • Mechanical cutting • Copy paper • Mcor • Selective gluing • Mechanical cutting • Copy paper • Color
  • 31. © 2014 Additive Insight LLC, www.additiveinsight.com Solid Ground Curing (Cubital) • 1991-2000 • 33 systems sold • Benefits • Very innovative • Highest throughput of all • First process to use a 2nd material for supports • Easy removal • Multi-component assemblies • Big issues • Massive (14’, 10,000 lb), complex, unreliable machine needing frequent repair • Costly to operate (consumables, maintenance)
  • 32. © 2014 Additive Insight LLC, www.additiveinsight.com Other Deceased Companies • BPM • 1988-1997 • “Ballistic Particle Manufacturing” • Took 8 years to ship machines, yet even then… • Poor performance and reliability: many initial customers returned their machines • No clear advantage over FDM, 3DP, etc.; poorer materials and speed • Quadrax • 1990-1992 • Stereolithography copycat • Sold 2 systems before 3D shut them down
  • 33. © 2014 Additive Insight LLC, www.additiveinsight.com Direct Metal Printing: A Long Time Coming… • Incre: Metal droplet printing • U. Nottingham: 3-D welding • USC / Microfabrica: Electrochemical Fabrication (EFAB)
  • 34. © 2014 Additive Insight LLC, www.additiveinsight.com EFAB * * Now MICA Freeform
  • 35. © 2014 Additive Insight LLC, www.additiveinsight.com PERSPECTIVES
  • 36. © 2014 Additive Insight LLC, www.additiveinsight.com Early Issues • Shrinkage and distortion • Still an issue • Brittle parts • Supports • Bridgeworks helped (1991) • Remain an issue, esp. for metal • Lengthy file prep • Messy materials
  • 37. © 2014 Additive Insight LLC, www.additiveinsight.com Some Lessons Learned from History • It’s harder than you think (even for large companies) • Cost isn’t everything • Keep it simple • The competition matters; make sure pros > cons • True innovation often comes from startups and universities: it needs strong patent protection
  • 38. © 2014 Additive Insight LLC, www.additiveinsight.com For Industry Historians • The Rapid Prototyping Patent Museum additive3d.com/museum/mp.htm • Wohlers Web site wohlersassociates.com • Rapid Prototyping Report
