3D PRINTING & SCANNING Gartner's Hype Cycle

3D PRINTING & SCANNING Gartner's Hype Cycle

Both over 20 years old, actually 30 years old

• largely industrial with recent consumer interest

• Was $100K+ equipment cost with now sub-$1K

Range of objects

• physical world has huge size & complexity variation

Massive change over last 3 years

• “desktop” and personal 3D scanning

• 123D Catch and Xbox Kinect

Future – what’s next?

• who needs 3D scanning and why?

• what will be the ‘killer apps’?

3D Scanning vs. 3D Printing

Traditional 3D Printing & Additive Manufacturing

• Visual aids for engineers,

designers, sales, medical, etc.

• Presentation models, such as

architectural or prototypes

• Prototypes for assembly fit checks

• Patterns for tooling and castings

• Guides for surgery procedures

• Functional short run production

• Education and research

• Other

What else is being 3D printed?

Projecting the future for 3D printingMarket Research and Analysis - Source: Pete Basiliere, Research Director at Gartner

�Growing demand for easy-to-use tools and materials

� Prices to drop with competitive pressures and higher unit sales

� Advances in 3D printers & scanners, design tools, and

materials will reduce the cost and complexity of creating 3D

printed item

� Businesses are only now beginning to fully comprehend ways

in which a 3DP can be cost-effectively used in their

organizations

�Makers and hobbyists will contribute to some form of “plug

and play” tool — that will be key to driving consumer sales in

future

3D printing remains a emerging market, despite high levels of hype:

Considerations

� Define your niche: What customers

will you best serve?

� What role: Will you print as a service,

sell the equipment or both?

� Which Equipment & Materials?

� Content: Where will it come from?

Who will own it?

� Data repair: How will you address the need for scan data processing

into 3D printable files?

“…making stuff is going to become more localizable. ..more objects can be manufactured closer to the end customers.” (Peter Weijmarshausen, CEO Shapeways –BARRONS.COM 5/9/14)

Microsoft 8.1 has added a "direct pipeline" from 3D printing applications to 3D printers-(PC Magazine – 7/2/13)

About HP - The company believes that 3D printing is a natural progression of its 2D printer business, where it has a sizeable share. (FORBES.COM – 3/28/14)

3D Scanning

The DDI technicians scanned four different sculptures: the Amun, the Headless Princess, the Scribe, and a Kneeling King Tut. An articulating arm-based laser line scanner provided high accuracy and real-time feedback to assure complete capture before heading back to Baltimore to process the raw scan data.

Ancient Sculptures

3D Modeling

For the post-processing, we used Innovmetric’s PolyWorks Modeler software to create highly accurate watertight 3D digital models of each of the ancient pieces.

Ancient Sculptures

Data Analysis

During both the scanning and modeling processes, specific attention was paid to fine cracks and other imperfections in the original pieces. These are the qualities that would make the reproductions more accurate and realistic.
