During my final bachelor project, I combined my gained knowledge in food technology with design in the project UPPRINTING FOOD. In line with my vision on sustainability and food, the challenge was to create a food concept from food waste with the 3D food printing technology.

My personal development in the expertise areas are together forming my design and research processes and professional skills. My skills in creativity and aesthetics are most developed, and are also leading in my design process. I showed my skills in managing the process individually by defining and setting up this project myself. I addressed the societal context of food design and planned the whole process by writing a plan of approach.

I involved stakeholders and experts in my process, who were needed for both the development and the validation of the final concepts. The collaboration went smoothly and I really enjoyed to set up this network.

For each expertise area I will elaborate my level of development.

Business and Entrepreneurship

To set up the project UPPRINTING FOOD, I built a network with external stakeholders, which I planned to do this semester to develop within this expertise area. Antien Zuidberg, lector in Design methods in Food at the HAS was defined as my client. Antien gave me the opportunity to use the facilities at the HAS, including the 3D Food Printer. Also, due to her background, she was able to provide me with information about the food properties I sometimes needed to continue in my process.

I also had contact with TNO, at which I was invited to print with their food printers. They learned me more about the technology of the printers. Other stakeholders were taken along in the process to validate the concept (De Verspillingsfabriek, Eurest and byFlow). I succeeded to inspire these stakeholders in a way that I am invited to continue developing my 3D food printing skills in a cooperation.

Other important previous learning activities for this expertise area, were my learning line New Product Marketing and the development of my business plan for the project SmartTap.

Creativity and Aesthetics

The creative electives (Basic Formgiving Skills, Exploratory Sketching & Digital Craftsmanship) I followed during my bachelor, where the courses I mostly enjoyed, because I really preferred to learn these skills and I appreciated the way of learning. The courses supported me with the acquired skills to develop my vision on aesthetics and the skills to finish and communicate my work really smoothly. Also, they learned me to be inspired by the work of other designers, by reading books and observing their processes.

The process of learning by doing fits well in my approach to design. During UPPRINTING FOOD I started experimenting with the material (the food paste ingredients), and reflected on the result by which I gained new inspiration and discovered the different steps I had to take during the process.

I prefer to create my designs by hand, but for designing 3D shapes I learned to work with the 3D designing program Fusion 360. I succeeded in creating exclusive 3D designs, instead of the extruded 2D designs which are often used when 3D printing food.

Technology and Realization

During the project UPPRINTING FOOD I became comfortable in working with the 3D printing technology. I succeeded in creating a material with a composition which was printable, with an appropriate thickness and flow. I reported every experiment I did, to analyze what was needed for the development of the material. Also, by working often with the food printer, with several food pastes and designs, I learned how to influence the results, by adjusting the settings on the printer interface and in the converting software Slic3r.

I did not need to build an electronic circuit myself during this project, but I developed this skill during the courses Creative Electronics, Creative Programming and the project Cycle Circuit.

Math Data and Computing

In Wageningen I learned to process the data I gained from the experiments during the lab classes in Excel and to execute statistical analyses. Also, during the course Making Sense of Sensors I learned to create data sets from users. During my project I created data sets of the experiments I carried out and data sets from the user test I executed. From these data sets I was able to find patterns and to draw conclusions. They helped me to create a final food composition. Next to that, I chose to follow the elective Digital Craftsmanship this last period, in which I implemented data and mathematics in the code I wrote in processing to create personal patterns on fabric with the laser cutter. The fabric was used for creating a travel bag.

User & Society

The societal challenge in this project is in line with my focus of sustainability and food in my vision as a designer. The challenge was to reduce food waste by creating a 3D printed food concept from residual food flows. During this project the user test was set up as an event, I succeeded in gaining enough promotion and 29 interesting users. The test itself was a combination of a focus group and a questionnaire, in which I evaluated both the use of the 3D printing technology, the taste, structure and use of residual food flows. I really enjoy to design with and for people, to create value for them and to know what their needs are or to discover if they use the project as how I did imagine. During my bachelor, I investigated the target group in all my projects and in some courses. During the courses User-centered Design and Innovation by Design, I learned several methods for how and in which stage I could implement the user.
