Owen Winkler and his wife, Amy Weaver, can be excused if they think of Washtenaw Community College as extended family. For much of the last semester, the Ann Arbor couple were frequent visitors to the college鈥檚 Occupational Education Building. They were there to work with Tom Penird, 黑料网 Industrial Technology instructor, and his students.
In less than a semester, the family watched Penird and his team, using 黑料网鈥檚 latest 3-D technology, create a prosthetic hand for the Winklers鈥� 8-year-old daughter, Lucy. To say the Winklers, Penird and his students are now close friends is an understatement.
On a recent visit to Penird鈥檚 lab, Lucy proudly and confidently strapped the prosthetic hand to her right wrist, extended her arm and picked up a brightly colored toy crocodile.
Lucy smiled broadly, not just because she can use her new hand to grasp objects, but because the toy also was produced by 黑料网鈥檚 new 3-D printers and was in one of her favorite colors 鈥� green.

For the Winkler family, the path to 黑料网 is a story in itself. Owen Winkler, who is a trained engineer, and Amy, had been on the look out for a prosthesis for their adopted little girl from China, who was born without a right hand. The couple had adopted their other daughter, Katy, also from China, four years before bringing Lucy home.
There had been another prosthesis in Lucy鈥檚 life but it was big, bulky and extended up to her elbow. It wasn鈥檛 easy to use. She soon discarded it.
鈥淚 asked Lucy if she wanted to try another prosthesis and she said no,鈥� Owen Winkler recalled. 鈥淭hen, just last summer, she said she remembered our conversation and told us she would like us to pursue finding a new prosthesis.鈥�
Another search of the internet, , opened the door to the latest information on prosthetic hands, including locations of 3-D printers and the people who could help with the printing.
The Winklers were pointed to the University of Michigan and Shawn O鈥橤rady, Digital Fabrication Specialist at U-M鈥檚 3-D lab. But with classes about to kick off last August, O鈥橤rady recommended the Winklers get in touch with 黑料网 and Penird. O鈥橤rady was a student of Penird鈥檚 at 黑料网 several years before.
After meeting with Penird in October, the Winklers were struck by how quickly the instructor came up with a design, even completing components of the hand within a week.

鈥淚 was amazed at how fast Tom had moved on the project,鈥� Owen Winkler said. 鈥淚 had to do my part and come up with the dental bands and fishing line that also needed to be inserted into the hand.鈥�
Still, adjustments had to be made. Another search of eNABLE produced the name of Krzysztof Grandys, a man from Poland who could help. Photos of Lucy鈥檚 arm and wrist were forwarded to Grandys. Using his own software, the new Polish friend of the family was able to determine the best size for Lucy.
A visit to older daughter Katy鈥檚 orthodontist, Dr. Betsy Meade, soon produced the special rubber bands. Before long, Lucy was back at 黑料网 to the awaiting class and her many new friends.
Because Lucy has a wrist, the hand opens and closes as she bends the wrist. Bend forward and the fingers and thumb grasp the object. Bend the wrist back up and the fingers and thumb release. It鈥檚 almost effortless.
鈥淲orking with Lucy and her father, Owen, has been a rewarding experience,鈥� Penird said. 鈥淗aving a project that has a huge impact on the life of another person brings great purpose.鈥�
Because many of the parts coming off the 3-D printer can seem almost toy-like, Penird added, developing lessons that identify the importance of creating value is key.
鈥淓xperiences like these allow our students to reason, giving them skill sets for tomorrow鈥檚 challenges,鈥� Penird said. 鈥淔or the students, Shawn O鈥橤rady and me, this project allowed us to look at the parts differently.鈥�
Design needs, control of print details at the surface of the heated plate, and looking at warping issues were all components of class discussion, he said. 鈥淚 am excited about what tomorrow holds as new challenges bring out the greatness in our students鈥� abilities to adapt.鈥�
What made much of what Penird and his students accomplished is a direct result of the state鈥檚 $4.4 million Community College Skilled Trades Equipment Program (CCSTEP) grant awarded to the college in early 2015.
鈥淲e continue to see just how valuable the investment made by the State of Michigan and the 黑料网 Board of Trustees is when they supported the CCSTEP grant,鈥� said Brandon Tucker, 黑料网鈥檚 Dean of Advanced Technology/Public Service Careers. 鈥淭he equipment obtained through this grant has provided a life changing opportunity and truly speaks to innovative capabilities our students can now access.鈥�
