UM3D Lab Introduction

• UM3D Lab is charged to support all research and
  educational activities that require advanced 3D
  data related assistance
• Focus on VR, stereo display, RP, digitization,
  course lab, custom programming, grant
  co-authoring
• Director Dr. Klause-Peter Beier, 5 full time
  staff students

4
UM3D Lab RP facility

• ZCorp 310 run as a service to whole UofM
  community
• Low energy out, low energy in cost propagation
• Parts built at cost, but not for free, for UofM
  users
• Allows for experimentation and failure without
  significant investment, most valuable form of
  education
• Shipai wa seikou no hajimari. From failure
  begins success.

5
Educational Support Whole Classes

• Integrated Product Development,
  http//www.tmi.umich.edu/IPD/index.htm
• Aerospace senior design course
• School of Art, digital design course

6
Student Support Projects, Thesis or Fun

• Student projects support, thesis work, personal
  projects
• The UM3D Lab machine runs an average of 3 times
  per week over the whole year, since 2003

7
Student Projects SFF (RP) Course

• Functional testing of turbo machinery components
• Additive technique allowed complex design
• Pre-Whirl is difficult to achieve, requires
  experimentation

16
UM3D 3D Digitization and RP
17
UM3D 3D Digitization and RP

• Laser scanning direct to .stl format
• Contact probe for parametric or cavity work
• Flexible CMM tools are critical in edu-lab
  environment

18
UM3D Lab RP Research RM Casting
