3D printing: more than just modeling

3D Printing at Dunwoody is more than just prototyping of parts.

Engineering Drafting & Design students were recently tasked with creating their own golf putters. Students designed putter heads in SolidWorks and printed prototypes using the College’s Stratasys 3D Printers. But they didn’t stop there. Students then took their models to Chicago Avenue Fire Arts Center to make metal castings of their designs before machining and refining them into polished, ready-to-use golf putters.

A growing enterprise

Not many 19-year-olds can say they own a business. Even fewer can say they started that business when they were 12. But Dunwoody Engineering Drafting & Design student Aaron Rasmussen can.

Rasmussen is the sole owner of Rasmussen and Associates, a lawn care, cleaning and moving service in Winsted, Minnesota. Despite being just out of high school, Rasmussen has upwards of 30 seasonal employees as well as some major customers. And the client list keeps growing.

Recently Rasmussen & Associates was hired on by several local banks to help clean out and spruce up foreclosed properties all over the state, including towns like Bemidji and Detroit Lakes.

What started out as a friendly favor quickly evolved into a large, successful business; and likely no one is more surprised by that than Rasmussen himself.

Starting Rasmussen & Associates

Rasmussen has always had an interest in managing. From high school clubs to part-time jobs, Rasmussen has consistently found himself in leadership positions.

But when it came to starting his own lawn care business? Well, according to Rasmussen, that venture began almost unintentionally.

It all started when Rasmussen’s neighbor asked him to cut her grass. He agreed, not anticipating how much his neighbor would like the end result. Word traveled quickly, and soon Rasmussen was working all over the neighborhood.

It didn’t take long before Rasmussen had more requests than he could handle. He needed help. So, he asked a few of his friends to join him, splitting the payment.

“I realized I could make money doing that,” he said. And just like that Rasmussen and Associates was born.

As if balancing high school, his lawn care business, and his part-time job wasn’t enough, Rasmussen also had a second part-time job working at Lester Building Systems, a leading pole barn manufacturer. 

Here Rasmussen managed the company’s 3-D printing activity, specifically designing products to improve the day-to-day activities of residential construction workers.

Several of Rasmussen’s ideas have been adopted and mass-produced by the organization. In fact, next summer Rasmussen will visit Lester’s corporate headquarters in South Carolina to see a machine he designed become a reality.

Rasmussen said it was during his time at Lester Building Systems that he realized his love for designing and 3-D printing. And despite owning a successful business, Rasmussen knew he was ready for something more. So, when he saw that Dunwoody had a degree in Engineering Drafting & Design — and access to some of the most advanced 3-D printers in the world — Rasmussen was sold.

Despite only being a few weeks in, Rasmussen has already founded a Combat Robots club and was elected Treasurer of Student Government.

After college, Rasmussen wants to continue with product development, specifically in 3-D printing for the construction industry. A Dunwoody degree will help with that, he said. And one day owning his own 3-D printing company? Well, that would be the dream job.

His advice for young entrepreneurs out there is to just do it. But make sure you’re a personable boss and you’re okay with putting in long days.

“I don’t sleep much,” he laughed. “But, other than that, it’s pretty good.”

Students Design and Build Weed Whip Prototypes Using Stratasys 3D Printers

Students pose with their weed whip prototypesOn Wednesday, Sept. 30, six groups of second-year Mechanical Design students presented their custom-designed weed whip projects and demonstrated their prototypes on Dunwoody’s lawn. Instructor Alex Wong gave each group the motor and wiring from a standard Black and Decker weed whip, a budget of $200, and about five weeks to make design improvements on the store-bought Black and Decker weed whip model.

“In addition to the professional skills required for the 3D modeling and documentation, the students also had to do a lot of problem-solving,” Alex said. The students were required to do research and develop sketches of their own weed whip concept. When this initial design process was complete, students brought their sketches to life using parts they made with the Stratasys 3D printers in the College’s Metrology Lab.Student tests weed whip prototype

Mac Cameron – an Applications Engineer at Stratasys – came to watch the demonstrations of the students’ projects. “I travel all over the place to see what people are doing with our printers,” he said, “but this is one of the cooler projects I’ve seen on a college campus.”

In addition to the project guidelines, Alex also graded students on criteria like teamwork, decision-making skills, and quality of the documentation.
