DESCRIPTION
This technical session will demonstrate how you can utilize 3D data collected from longer range laser scanners, to produce models of objects, architecture, and even landscapes. Using examples from archaeological projects around the world and from their museum exhibit featuring 3D printing and 3D laser scanning, University of South Florida scientists will demonstrate workflows they are using for World Heritage preservation projects, and show how they are using these 3D data and objects to enhance and improve education and interaction. Learn how 3D printing is providing exciting new deliverables and the possibilities for added value on a variety of projects.

Who we are and what we do:
• We are a Center at the University of South Florida, working to preserve and protect the world’s cultural and natural heritage through education and global engagement.
• Our goal is to create interdisciplinary approaches to research and curriculum using 3D technologies, visualization and other spatial documentation methodologies.
• Heritage studies are the core of our research and educational mission

AIST is a Center of Research in the School of Geosciences at USF, that is working to preserve and protect the world’s cultural and natural heritage through interdisciplinary research, education, and global engagement. http://aist.usf.edu
Heritage Preservation: Integrated Approaches
Essential Aims of Survey
“To record, to be accurate and precise, and to be representative”

Why We Do It: World Heritage is Endangered
1972 Today
The World’s heritage is disappearing at an alarming rate. We use the latest advances in things like 3D laser scanners, imaging, wearable computing and 3D printing. We record archaeological treasures that are imperiled, giving them a digital life so they can be shared, preserved, and safely kept for everyone.

Educating with 3D Projects
• Teaching and learning is improved through immersive and innovative means with direct impacts on student achievement
• A study of schools in Europe found that the impact of 3D in the classroom improves test results by an average of 17% and that 3D tools help students concentrate more

Engage with Methods for the Future:
Technologies can allow us to record, analyze, interpret
and share in new and innovative ways (also more accurate
and representative)
Increasing our global capacity for collaboration
Portable, accessible, rapid
New technologies allow us to see, engage, and share in
real time
BYOD (Bring your own device) – smart phones and
tablets
Wearable computers

Our Facilities for 3D Printing
Dimension sst-768 and the ZPrinter 450, Cube (3D Systems/Duo, Trio) and Makerbot (numerous consumer grade printers)
Accepts files in the STereoLithography (STL) formats
Materials: PLA, ABS, Powder Resins, lots of others…
Fused Deposition Modeling (FDM) - 3D prototyping printer which uses ABS plastic to build parts and assemblies. Fused plastic is both strong and durable
Powder and binder systems (e.g. gypsum based powder +starch based binder + infiltrate)
Useful for Proof of Concept, Functional Testing, and Product Mockup, Interpretation, Education, and other Research
http://aist.usf.edu
3D Mishaps and Mess-ups
Issues with small features and intricacies
Model has to be water-tight and STL QC QA check
Build box size limitations
Length of time issues, heating and extruding errors, etc.
