מדפסות תלת מימד בשיטת SLS- Selective Laser Sintering.
חומרי הגלם של מדפסות ה SLS הינם פולימרים בתכונות חומר סופיות כגון ניילון, ABS, חומרים עם סיבי זכוכית וחומרים מעכבי בעירה.
הדפסת תלת מימד בטכנולוגיית SLS מאפשר לייצר מודלים לשימוש סופי מכיוון שחוזק וצפיפות החומרים הינה 99% לעומת שיטות ייצור אחרות.

22. Custom Tooling
• Coolant Nozzle
– Conventional method
– Round nozzle
– Did not dissipate heat
– Stressed finished parts
– Direct Manufacturing
– Conformal cooling
– Evenly cools part
– Less Scrap
23. Custom Tooling
• Weld Fixture
– Conventional Method
– Aluminum Plates
– Lead time of 3-4 weeks
– $1,500 per fixture
– Direct Manufacturing
– Lead time 2-3 days
– $300 per fixture
24. Cheetah Tool
• Savings over $200,000 in tooling
• Lead times dropped by months
“If the 3D Systems’ technology wasn’t available, I would have needed a million
more dollars and with all the intricate parts, it would not have been possible
to complete the riveting tool,” Fulbright said.
25. • Over 200 brackets
fabricated in one
build.
• Delivery of inspected
and certified brackets
in one week.
Batch Manufacturing
26. Medical Devices - Zimmer
• Patient Specific Devices
• Conventional method
– Manual cutting and drilling of bone Surgical expertise required
– Improper alignment
– Longer operating times
– Large Inventory
• Direct Manufacturing
– Doctor preplans surgery
– Matches patient exactly
– Reduced Inventory
– Reduced items for sterilization
– Minimizes doctor to doctor variation
– Reduced procedure time

“The long-term aim of this research is to allow members of the public to have their own
personalized footwear,” Hopkinson added. “Achieving success with elite athletes will prove to be
the catalyst, allowing our processes to be applied to everyone.”

32. "Using state-of-the-art laser sintering technology, ODM will produce
complex parts more quickly and with fewer tools than traditional
manufacturers. This will allow ODM to keep acquisition and operation costs
low while providing just-in-time manufacturing services that more
customers are demanding." Anil Shrikhande, vice president of Boeing Ventures
