Dana Green (Exact Metrology) and Gail Ray (artist) review project
By Dean Solberg
As technology rapidly advances, its uses are benefitting nearly every industry, and the world of art is no exception. Brad McConnell, a mechanical design instructor at John T. Blong Technology Center, Davenport, Iowa (Eastern Iowa Community College), wanted to expand the types of projects offered for the school’s mechanical design program. He hoped to incorporate one of the newest types of advanced technology — 3D scanning, which can quickly and accurately capture the image of a person or an object with white light to create a 3D model. Knowing that the school wasn’t equipped with the latest equipment, McConnell reached out to Exact Metrology, a metrology services provider with a complete line of 3D scanners, industrial CT scanners, 3D printers, reverse engineering and quality inspection. Exact Metrology stepped in and readily agreed to provide their scanning services to the school.
Dana Green works with data on computer
Gail Ray, a mechanical design student at the community college, and former architect, is currently completing her Honors Independent Study classes in Additive Manufacturing and Subtractive Manufacturing, with an emphasis in Technology in Art. As an architect by trade for almost 30 years, Ray is well-versed in both areas of art and technology. She chose this path of study to combine her interest in portraiture, 3D modeling and printing. As a final project for her Additive Manufacturing class, she chose to create a 3D lifesize sculpture of the upper-body bust of a live person.
Dana Green, Applications Engineer with Exact Metrology since 2014, traveled from his home office in Brookfield, Wisconsin to Blong Technology Center in Iowa, equipped with the latest, state-of-the-art scanning equipment; an Artec Eva 3D handheld scanner. The Artec Eva scanner scans fast, capturing and simultaneously processing up to two million points per second with up to 0.1 mm accuracy. It employs structured light technology, and is safe for scanning live models.

Using the 3D scanner, Green was able to scan Ray’s chosen model, fellow mechanical design student, Ketzalli Dondiego. He took a full body scan of Dondiego to allow Ray flexibility for future projects. In roughly 15-20 minutes, Green had about 4 Gigabytes of point data which was refined down to a more manageable file of 75 megabytes during post processing. “It was exciting to see such accurate results done so quickly” stated Ray. Ray also said that Green shared information on the software and processing, which helps the learning curve immensely.
Green then spent time in post processing using Artec Studio 12 software. He manipulated the data collected to make sure everything aligned properly. He provided Ray with an STL format the next day. Ray then had the scan 3D printed in full size. She plans to create a silicone mold from the 3D print, which will allow her to cast the form in different materials, including plaster. At the same time, Ray will use the scan for a second class she is enrolled in, on Subtractive Manufacturing. In this project she plans to make a more modern art type sculpture, or “Picasso-Esque” as described by McConnell, from wood using a CNC mill and a 3-axis machine. Ray plans to have both projects completed by December.
Ray is hoping to showcase her work at the Figge Art Museum in Davenport, Iowa in an upcoming show titled, “Art & Technology.” Although it is not finalized yet, she hopes to show not just her piece, but also the entire manufacturing process of how it was developed, possibly through a video playing in the exhibit. Ray is passionate about her work, and how much the combination of art and technology can offer, and wants to get the word out. She said, “My point is, if you have an idea, 3D technology allows you to get to a prototype, something you can hold in your hand, quickly and inexpensively as compared to the pathways in the past people had to take.” She considers her artwork a device that will educate the community and students of the exciting new advances in 3D modeling and additive manufacturing.
Additive manufacturing and 3D laser scanning are advancing almost every industry today, and are being used in areas from hospitals to Hollywood. According to McConnell, “The opportunities are endless. If you can think about it and model it, you can 3D print it.”
