Process Mapping Methods for Integrated Control
of Melt Pool Geometry and Microstructure in Direct
Metal Additive Manufacturing
Jack Beuth, PhD, Professor, Department of Mechanical Engineering,
Carnegie Mellon University
Control of melt pool geometry and microstructure are critical
concerns for direct metal additive manufacturing process
qualification within the aerospace and other industries. This work
demonstrates a P-V Process Map TM approach for mapping the
role of major process variables in determining: 1) key melt pool
dimensions, and 2) microstructural features. Combining these
process maps further leads to an approach for indirect control
of microstructure through direct control of melt pool geometry.
In this talk, methods are applied to wire-feed electron beam
AM processes. Modeling results over a wide range of process
variables are presented to illustrate the approach for deposits of Ti-
6Al-4V. Experimental results are presented that are consistent with
the model predictions. By linking microstructure control to melt
pool geometry, which can be monitored in-situ, the number of tests
and microstructural examinations needed for process qualification
can be significantly reduced. These methods can also be the basis
for advanced approaches to thermal imaging feedback control.
3D Imaging & Scanning
1:30–5 pm
This session will cover applications that make use of scanning
technologies for reverse engineering, analysis and inspection
that contribute to the manufacturing of products using additive
and 3D printing processes.
1:30–1:55 pm
Preserving the Past, Developing the Future—
A Collaboration of Emerging Technologies
Vince Anewenter, Manager of Operations,
Milwaukee School of Engineering
District of South Carolina. Vince Anewenter, RPC manager of
operations, used 3D laser scanning to create an exact digital
copy of an original face jug. Using the digital file, Anewenter and
biomedical engineering student Nora Huang worked with Brian
Gillis to convert the model into a functional time capsule. MSOE
used a variety of specialized CAD softwares to manipulate the
original scan file into the final functional time capsule design.
Using Selective Laser Sintering (SLS) technology the RPC
additively manufactured the actual time capsule. The nylon SLS
model was then coated with .005 nickel by RePliForm Inc. in order
to provide the physical and aesthetic properties required.
2–2:25 pm
Structured Light 3D Scanning Fundamentals
Thomas Tong, President, 3D3 Solutions
We plan to cover a range of topics around the process of
performing structured light 3D scanning. We’ll start with laser
vs. whitelight/structured light since most people are familiar with
how laser scanners work but not how structured light scanners
work. Next, we will discuss some of the perception versus the
reality of the current state in the 3D scanning process. We
will also cover the 3D scanning workflow in depth, specifically
part mounting and part preparation, alignment strategies, 3D
scanning, and how to do scan data cleanup and analysis.
2:30–2:55 pm
Wearable Technologies Benefit From 3D Imaging
Aaron Trocola, BS, Founder, Threeform Fashion
3D scanning and 3D printing systems have been used in
combination in medical, industrial and scientific, and–more
recently–in functional apparel and fashion. Of course it is
also being used heavily in prototyping and in some cases
producing the body-interface portion of wearable products and
technologies. This paper will focus on consumer applications and
explain why we see the wearable space is ready for innovation.
MSOE’s Rapid Prototyping Center helped the Chipstone
Foundation and commissioned artist, Brian Gillis, to create a time
capsule in the image of a historical artifact which will serve as a
center piece to a traveling sculpture exhibit. The exhibit, “Face
Jugs: Art and Ritual in 19th-Century South Carolina,” features
face jug vessels that were created by slaves in the Edgefield
