Using MAHAM to Create Unique 3D Parts
Nebraska engineer Michael Sealy is using multi-process asynchronous hybrid additive manufacturing techniques to create lighter and stronger metal materials that could have life-saving and money-saving applications. His research is supported by a five-year, $500,000 award from the National Science Foundation’s Faculty Early Career Development Program.

[00:00:00.200]My name's Michael Sealy, I'm an assistant professor in
[00:00:02.700]Mechanical and Materials Engineering.
[00:00:05.100]My background is in advanced manufacturing,
[00:00:07.900]and I do a lot of laser-based manufacturing
[00:00:10.130]which includes, of course, 3-D printing.
[00:00:12.790]It's a metal additive manufacturing.
[00:00:14.710]My career ward focuses on using what we call
[00:00:17.930]Multi-process Asynchronous Hybrid Additive Manufacturing
[00:00:21.275]or M.A.H.A.M. is the acronym the fancy acronym
[00:00:24.320]and the reason we call it M.A.H.A.M. is because
[00:00:25.980]we're gonna upset pretty much how we manufacture
[00:00:28.589]every single critical high-value component today.
[00:00:31.980]We're gonna combine additive manufacturing with
[00:00:35.220]surface based technologies and surface streaming to
[00:00:37.450]change properties layer by layer and essentially
[00:00:40.330]print our own mechanical properties.
[00:00:42.626]I started in this research area because I have
[00:00:44.457]a personal connection to it.
[00:00:46.640]I have two screws in my elbow that were
[00:00:48.410]put in when I was about two years old.
[00:00:50.490]The problem is that they're permanent.
[00:00:52.639]So many year down the road I'm to a point now
[00:00:54.820]where I'm gonna have to have a second surgery
[00:00:56.040]to get these taken out.
[00:00:56.873]Nobody wants to pay for a second surgery,
[00:00:58.530]nobody wants to go through a second surgery,
[00:01:00.600]insurance doesn't wanna cover the cost for that,
[00:01:02.770]and so we could avoid those types of situations
[00:01:04.940]just by having a biodegradable implant.
[00:01:07.870]And so that's what we're focused on is
[00:01:09.530]eliminating the need for the second revision,
[00:01:12.610]or removal surgeries by using a biodegradable metal implant,
[00:01:16.470]which is kinda innovative in itself,
[00:01:18.270]but in Nebraska what we're doing is
[00:01:19.480]stepping it up a notch and making it to where we can
[00:01:21.490]tailor that degradation to each individual patient.
[00:01:25.130]With a career ward you have a research component,
[00:01:27.440]but you also have an educational component
[00:01:29.320]and the educational component of my career ward
[00:01:31.380]focuses on what I call the dream program.
[00:01:34.000]Discovering, Research, Entrepreneurship and
[00:01:36.460]Apprenticeships in Manufacturing.
[00:01:39.220]And so it focuses on building this
[00:01:41.790]entrepreneurial culture in the college of engineering.
[00:01:44.790]Pushing for more startup companies to
[00:01:46.420]try to commercialize their research.
[00:01:48.220]It also includes apprenticeships,
[00:01:49.900]additive manufacturing is one of the most
[00:01:51.480]under-served areas in manufacturing right now.
[00:01:54.002]We're also building upon the partnership that we've had
[00:01:57.490]since about 2014 to 2015 with Navajo Tech.
[00:02:01.097]Native Americans remain one of the most
[00:02:03.120]under-served communities when it comes to higher education.
[00:02:07.100]So we're really trying build what I call
[00:02:08.780]Trans-national research experiences.
