Slide: /
  
Learned to challenge and evaluate a common configuration of filament 3D printing.
Iteration 1
Spring 2024 Midterm
Grade: 90%
  
We proposed a novel approach to modulate the flow rate of FFF printing and a test plan.
Compared performance of 1, 2, 3, 4, 5, 6, and 8-sided gears with the same perimeter.
The gear must resist 10s of print hours, have a rough circumference, accept 2 set screws and a d-shaft. Metal Binder Jet Printing (BJT) from an online vendor was selected.
Saving cost (from minimum volume req.), all gears were ordered as a single piece of stainless 17-4PH and were cut apart.
With each gear, I printed 3 samples of:
  
Each orientation of a bending coupon (left)
  
A tensile strength coupon (right)
All tests ran identical GCODE, avoiding the difficulties of any software-based extrusion rate modulation methods.
Used industry-standard gauges in custom fixtures for performance testing.

Systima, a division of Karman Space & Defense
5351 Argosy Ave, Huntington Beach, CA 92649

Attn: Mechanical Aerospace Engineering Internship (ID: 2039) Selection Group

I have applied for the mechanical engineering internship at Systima for this summer because I am a helper. Across the country at the Kennedy Space Center and about twelve years ago, I heard the news that the Shuttle program was coming to a close. However, the kind tour guide at KSC also told this ten-year-old that the first people on Mars had already been born. I exclaimed, “I don’t wanna go! I hate heights!” My mother chucked and added, “If you can’t go, you can help them go!”

Since then, historic advances in aerospace technologies by Karman Space & Defense and Systima were prepared for use by Artemis 1 through constant, thorough work. In that period, my friends and family have seen me set my path to be the best helper I can be. I’ve positioned myself in leadership and individually contributing roles where I can help the most. Progressing through a robotics team, machine shop, formula student team, and manufacturing plant, I have learned the process of creating technical drawings, fabricating, assembling, and verifying quality. As Karman Space & Defense is a safety-driven company, under intense scrutiny from public and internal stakeholders to create value, I recognize that the most important step is how to iterate the whole process for safety and only then for value.

My internships at ATI Industrial Automation allowed me to collaborate with a community that is making a significant impact on the Earth (and Mars) through robotics. In the design verification laboratory and the robotic applications development group, I contributed to preproduction meetings discussing testing and quality requirements. The individuals of ATI have succeeded in their field because their breadth of engineering understanding and interpersonal insight creates opportunities. I am now starting to see my breadth of experience growing to bear fruits in self-started projects.

The most recent of these fruits is my website and design showcase www.iterable.design. I coded and built this site to more easily display my engineering progression in today’s online world, and because it was hard to do. I learned how to shrink my ideas into a meaningful presentation with real consequences if I fail. I've found that my most fulfilling projects have been those that help others and bring them joy.

As a lead instruction coordinator of the Mechanical Design II course at the University of Florida, I’ve demonstrated my passion for technical communication and the design process. I am also very active in the College of Engineering as a leader in two engineering honor societies. These have enabled me to create membership volunteering opportunities to promote the value of engineering processes and skills.

Because helping is what I do, I know that Karman Space & Defense and specifically Systima is the place I need to be to help public, private, and internal technology partners reach their goals fast.

I appreciate your consideration,

Joseph Hill

I am delighted to write this letter of recommendation for Joseph Hill, who interned with us from May to August 2024. Throughout his time in our department, Joseph demonstrated many of the qualities that make for an outstanding intern, contributing significantly to our projects and team dynamics. 

Joseph worked on several key initiatives, including the development of a Card Reader Advanced Testing Wheel.This innovative tool provides a means to mass load systems and mimic a month's worth of data in just a few days, greatly enhancing our testing efficiency. He also conducted testing on 360-degree ceiling mount PIRs, showcasing his technical skills and attention to detail. 

In addition to these projects,Joseph co-designed and built quality lab elements that streamlined the testing of new technologies, ensuring a robust and efficient testing process. He worked diligently on electrical and data connection interfaces, which were crucial for our ongoing projects. Furthermore, Joseph took the initiative to standardize and organize our lab space for mechanical designs and prototyping, creating a more effective working environment for the entire team.

Joseph's written communication skills are excellent, and he demonstrated proficiency in PowerPoint, creating impactful presentations that effectively conveyed complex information. His ability to articulate ideas clearly and concisely was a tremendous asset during team meetings and project discussions. 

What truly sets Joseph apart is his dedication and passion for his work. He invested both heart and mind into every effort, consistently striving for excellence and inspiring those around him. His positive attitude and collaborative spirit made him a pleasure to work with, and he quickly became a respected member of our team.

Letter of Recommendation for Joseph Hill

To whom it may concern,


ATI Industrial Automation employed Joseph Hill as a co-op/intern for two rotations (two separate assignments). He worked on my team at the time, Application Development, during his second rotation. I was his direct manager. The Application Development team is responsible for developing new ways to use ATI products on industrial robots. This involves programming various different robots (all different proprietary languages), designing and sourcing mechanical tooling, documenting robot integration procedures, and creating instructional and marketing content. Joseph was involved in all of these aspects during his single semester assignment on my team.


Joseph Hill is creative, technically competent, curious, and motivated. I would highly recommend him for future employment or higher level education in the robotics field.


When he first joined my team, Joseph had never programmed an industrial robot. For his final internship project, he completed an instructional robot demo (using a collaborative robot) start to finish. I pointed

him to where he could find online and internal resources, and he then completed all of the training on his own. In addition to using the provided training resources, he designed tests to trial and error other topics. He knew when to reach out to help and when to figure something out on his own. I was very impressed with his quick learning abilities.


The robot demo involved learning how to program that particular robot brand (different from the one he originally trained on), designing mechanical tooling to use in the demo, writing a robot program to showcase specific product features and programming capabilities, and filming and editing a video (with voiceover) to share with customers. He went above and beyond by learning a more advanced robot programming feature (full custom tuning of force control) which better highlighted our product’s features. He also put in extra effort to professionally light the video set and use a professional microphone and editing software for the video. I was able to use his final product to get approval to use more of my full- time employee’s time on instructional videos.

Joseph Hill Letter of Recommendation Page 1

One of Joseph’s main duties was designing mechanical tooling for his own robot demos/tests, as well as for other employee’s needs. He was surprisingly adept at SolidWorks compared to his peers, and applied creativity to even the simple designs, making them cheaper/faster to manufacture, and more modular for flexible re-use in the future.


Joseph also assisted with new product prototype build, calibration, and testing. He documented the calibration and test procedures so that future interns could follow the process, and made suggestions to the product design that would make the builds & calibration easier and more reliable. It was obvious he was always thinking of ways to optimize a design.


Lastly, Joseph’s curiosity and unwavering determination to answer his unanswered questions make him particularly well-suited to a research or R&D type position. I look forward to seeing what he will do next.


If you would like additional information about Joseph Hill, please contact me.
