Incorporating 3D Printing into
Real- World Biomedical Engineering

Whether you’re a 3D printing aficionado or just getting started with this in the classroom, printing trinkets gets old quickly. When searching for your next project, why not take on something that flexes your creativity and benefits others?


3D Printing in the Real World

3D printing isn’t just something to create a spinning table top for a school project! Practitioners of Biomedical Engineering use this technology regularly. In fact, every time a prosthetic arm is prepared for a patient, customized work must be done to create the right fit. 

When a patient receives a prosthetic hand or limb it is usually ordered “off the shelf”. The new prosthetic must be fitted to ensure compatibility with the size and shape of the person’s arm, write, or remaining limb. Just like fingerprints, each person is slightly different in the shape and size of their amputation site. Additionally, some amputees have their full arm remaining while others have also lost their full forearm. 3D printing techniques allow prosthetists to create customized fits for every patient based on their needs.


The NeuroMaker Connection

NeuroMaker’s materials and culminating experience, the NeuroMaker Challenge, provide students the opportunity to apply their knowledge of prosthetic and assistive devices to solving a real world problem. Students are encouraged to implement new technologies, including additive manufacturing.

Educational Use Case: King Kekaulike High School

Team Digit Prosthetic Band from King Kekaulike High School in Hawaii 3D printed out a specialized Biomedical attachment to a prosthetic finger. These specialized parts allow a person missing a finger to add one artificial finger from an artificial hand onto their wrist for better quality of life.

Educational Use Case: Central High School

Team Commodores of Perry Central High School in Indiana 3D printed out a specialized digit for their prosthetic hand which allows the placement of a piezo sensor. This sensor allows an amputee to detect how much pressure is being applied to an artificial finger. This group of students discovered applications for an amputee holding a baby and ensuring that not too much pressure is applied.


3D Printing Pieces to Investigate for Customized Prosthetics

Depending on how much adventure you’d like to take on, there are multiple ways to design custom pieces to real world prosthetic arm projects. Here are some quick ideas!

Yasuhide Yokoi and Final Aim Inc’s Autonomous Delivery Robot

Yasuhide “Yasu” Yokoi is the cofounder of design and technology firm Final Aim Inc., which works with laboratories, startups, and multinational companies to transform ideas into tangible solutions. There, he and his team use Ultimaker 3D printers to better enable rapid design iterations during the prototyping phase.

One of the company’s latest projects is the OSTAW Camello, an autonomous package delivery robot.

Revolutionizing Package Delivery

The Camello was designed to address issues in the delivery logistics chain in Singapore, which causes high shipment costs and operational complexities. Due to low loads and long waiting periods in loading and unloading bays, package deliveries are often inefficient – a fact exacerbated by high delivery volumes and tight delivery deadlines.

To tackle this challenge, Final Aim collaborated with a Singaporean robotics start-up OTSAW Digital PTE LTD, with the Camello being the final product.

The Camello is user friendly, featuring an ergonomic cargo space and sleek design – optimal for Singapore’s urban environment. Plans are currently underway for it to be used by various industrial key players, delivery companies, and retailers throughout Singapore, creating an improved ecosystem that provides smooth and efficient delivery to customers, while increasing profit margins for those businesses that use it.

The Birth of the Camello

As with any product, several phases were involved in Camello’s design, with the Ultimaker S3, Ultimaker Cura, and CAD software acting as Yasu’s and Final Aim’s greatest companions throughout the process.

First came the robot’s concept development and evaluation. From the initiation to ideation, he used both hand-drawn design sketches and CAD software.

Once he developed the idea, Yasu began the process of presenting it to the higher-level management, frontline members, and end-users. This divergent approach allowed Yasu to gain as much feedback as possible, which he could then use to refine, improve, and further flesh out his concept.

Next came the prototyping phase. As Yasu now had numerous potential ideas, he needed to rapidly actualize them – often on tight deadlines. Luckily, this was a task that 3D printing was able to easily handle. Compared to other common prototyping methods such as sculpting or carving from Styrofoam, chemical wood, or industrial clay, 3D printing is much more efficient – freeing up time for Yasu to work on other design tasks.

“More than just cost-cutting, 3D printing has added value to my process,” Yasu said.

Finalizing an Intuitive Design

Yasu was also responsible for ensuring that the Camello’s final design was of excellent quality. As his works often incorporate organically curved surfaces and silhouettes, which are often difficult to implement, he needed to create numerous iterations. 3D printing technology utilizes the contour layers of printouts to analyze the curvature of surfaces – essentially an equivalent to the zebra mapping that CAD software performs.

“The Ultimaker S3’s double extrusion feature has [also] been essential to my everyday design applications,” Yasu said. “Together with Breakaway and PVA material, my printing experience has become exponentially more efficient. I am deeply satisfied with the resulting quality as it leaves behind no support structure remaining.”

For the Camello to be a success, its design had to be intuitive and accessible at first glance. The design process, therefore, involved divergent ideation, exploring all possibilities, which were then carefully narrowed in focus. Development speed was also critical for stakeholders’ requests.

3D printing enabled these stakeholders to see and touch a physical product, deepening their understanding of the Camello’s concept and design – and streamlining the decision-making process.
