“I’ve always wanted to learn what I can’t do, for if I always learn what I can’t do, removing obstacles in my way, then my talent automatically grows.” - Marcel Wanders Hi, i’m Leigh Walter A 26-year-old Mechanical Engineering studet in Coventry University, with an international exchange in Industrial Design Engineering at TUDelft. Through this year at TUDelft, design has evolved from just an interest if mine to a need. I aim to grow in the field of design. Like Marcel Wanders, I like working on things I can’t do, never stop learning. I hope therefore to work for a design agency where I can push my knowledge and abilities on a daily basis. I have two main areas of interest: creating functional products that improve peoples lives, alongside a recreational interest in furniture design.

Content My Skills Problem Solving Teamwork Communication Rendering/Adobe Computer Aided Design 3D Printing Like my grandfather before me, a Swiss Army Knife is something I carry. I find it the perfect analogy of the skills I have. Throughout the portfolio, this symbol will show the tools I not only believe I am good at, but those that I enjoy and look to improve throughout my future.

THEVARIOSEAT PROJECT 1 Alongside the clients Royal Ahrend and ColorFabb, my group had the challenge of replacing the soft areas of the Ahrend 2020 office chair with a 3D-Printed alternative using ColorFabb’s unique filament Varioshore TPU to create a unique and ultra- personalised seating experience. Leadership Teamwork Decision Making 2 Research From research reports and talks with two experts in the field; Peter VInk and Johan Molenbroek, we discovered what made a comfortable chair. We learnt that people are more sensitive behind the knees and less sensitive at the rear, and therefore a firmer back and a softer front of a chair would be ideal. Another point was that although a cradling effect provides a really comfortable seat, the ability to move around in a seat is vital for longterm comfort. 3 Mapping 4 Cura/Rhino Our research and material testing showed us there were Through Cura, it was possible to slice and print the seat with benefits to a 3D printing solution. Pressure maps for a a vaiable gradiated infill, prividing both a soft front and firm number of participants were therefore taken. It was decided back for long term comfort as well as an ultrapersonalied top that we were going to design an untrapersonalised and layer. portable top layer of the chair that allows the user to feel a cradling uniquily specific to them as they first sit. Using the initial impression in Rhino, an automated top layer pattern was made to reflect the internal structure of the seat.

5 Printing After testing with a modified ender3 Pro’s, Ahrend provided us with a CR10-MAX. Thw improved bed size allowed us to print the whole seat in just 4 parts (left). Through all of our tests, we were able to reduce the original printing time from over 7 days for the whole seat to just over 2 days. We believed that, with a printer built specifically for this task, that time could be reduced even further. FPirnoatlotype 6 ProjectVideo youtu be/ 5Ncc_cwb5K0 VIDEO 7 Project Review This was my first group project at TUDelft, and I was so proud of myself and my team. I am extremely proud of how we worked and what we created. It taught me a lot about leadership, the design process and 3D Printing. If I were to do the project again, I would argue the importance of redesigning the seat shape to allow flat printing and significantly improve top layer quality.

The ChairTransporter lets go together Goal: Design a low-budget electric powered vehicle that has the ability to: 1, carry a wheelchair-bound companion and 2, fit into an average sized car for transport purposes. My Role: Through this project, I lead all design discussions, including most design decisions, all CAD and rendering work. Process: We began by researching current solutions as well as concerns wheelchair users might have, for example tilting back over 30 degrees can disorient the user. After this, a number of design ideas came up, however a tricycle design was chosen to be developed as it seemed the most stable, and best option for allowing contact between user and passenger. Design: The design (below) had the ability to split into two to allow for a small footprint when storing and transporting. The rear axle also folded to decrease its area by half. This originally had motor driven rear wheels, which were replaced with a front hub motor to reduce complexity with the folding rear axle. This also reduced cost and power consumption by reducing the number of motors.

Final Design: The final design consisted of a mostly aluminium two parts chassis with a detachable front axle (right) which would hold the driver and all electronic components alongside a fold-able back axle (below) designed to carry the wheelchair-dependant passenger. This design allows the vehicle to be built using a lot of outsourced or second-hand parts, reducing costs significantly. The front axle comes off a bmx, and most parts external from the main chassis could be sourced second-hand, saving money. Results: The project didn’t do very well when it came to grading, and for a long time I was very unhappy with the result and project. My team was really unenthusiastic, and myself maybe a little overenthusiastic. If I was to work on this project again, I would look into cheaper alternatives to the aluminium, such as maybe a partial bamboo chassis to reduce weight and required tools to build. The frame mounting system would also be redesigned for a more stable/possible design. Looking back I notice that a lot of the project was completed by CAD myself . My team mates were very uninterested in the project Rendering and only worked on the theoretical parts. Decision Making I am proud of the work I put into it and it taught me a lot. I now better understand the importance (and ability) of distributing the workload and responsibility when it comes to working with a team.

Initiative The VaultBox CAD Personal Project Rendering Creativity Project Definition: Through 6+ years of coaching gymnastics and freerunning, I foud one of the most outdated pieces of equipment was the transportable vaulting box. When travelling with equipment from school to school, I found this piece of equipment the most difficult to move around and handle. It also has a large footprint when being stored. Ideation: Through the years I had thought there has to be a better way to design and build this equipment, whilst it remaims stable and safe to use. The design I came up with connected it through latches on each side (left), allowing the majority of the parts to be lightweight and simple shapes, as well as T-nut connections added for icreased functionality. See below for the final product and storage footprint comparison.

Interupted LampIllumination Personal Project As designers, we often work late nights and have the need for a bright work surface alongside an unobstructed computerscreen. This sleek lamp provides the perfect addition to any creatives workspace.
