3DBear Recycler Blog - Paul's Reflections - Entry #1

“He wanted me to build a machine.”

You should know right off that this is a long story, but I hope you'll find it interesting. There is enough of it, that I figured by breaking it up I could make a reasonable blog, talking about resources, DIY, dreams, and engineering. So I'll start this off by talking about how my buddy and I started working on the 3DBear recycler.

I'm Paul, and I became a student of engineering, because I was tired of watching poorly made and badly designed things break down, and become trash. It broke my heart to know so little about materials like the plastics that are accumulating in our oceans, and what to do about them. So I went back to school. The Arcada University of Applied Sciences in Helsinki, Finland has a program in material science, an engineering degree, so I spent the summer brushing up on my math, and tested in. I met Janne my first day at the school and we got along right away, talking about mechanics, and 3D printing, and possibilities.

Once I got started there I learned loads of reasons that things are worse than we thought they were, and loads of reasons that we can't do anything about it; but I wanted more, I wanted to know about the things that haven't been done yet, and the basics that could be used to develop new methods. So I applied for funding for a research trip, I wanted to better understand waste accumulation. So I went to Bali and convinced local villagers to participate in an ecological project where waste was collected and I did my best to see how quickly it was accumulating and what was being done about it.

The project was a success. I got good data, and I learned a lot of practical skills in the process. Additionally I got the attention of a startup called 3DBear, they wanted to meet me to discuss an opportunity with them. Kristo Lehtonen, one of the founders, strode into the coffee shop where I had agreed to meet him. He is a striking sort of guy, his smile lights the place up and he seems to have an unlimited optimism, traits that are more common in my homeland of California than here in Finland. 

I noticed immediately that nothing was small or commonplace with him. Instead it was overarching vision and seizing this very moment. Usually I find that sort of thing a little cheesy, but when Kristo tells you about it, you can almost see it. So he told me 3DBear was all about changing the world starting with education, and I am all about that, but he went on. 

He wanted me to build a machine. An ecological device that would transform waste plastic into 3D printing filament. 3DBear was scouting both Janne and I to make something new and interesting. I was processing his plan just fine until he said something that threw me off. He said once Janne and I finish building the machine, the entire project goes open-source.


Now that guy who was tired of watching poorly made and badly designed things break down, me; well that guy knew for sure that companies don't invest in open-source. I also knew that startups, and 3DBear was a startup that was two or three months old, startups don't make investments in projects like this. But Kristo was adamant, he and his cofounders were set on doing more than just "changing the world", they wanted to do it responsibly.

So I hope you can understand that I had no choice in the matter. I was working with people who honestly wanted to do the right thing, and had assembled a team with the right skills and passion to meet those goals. I was making accessible technology that changes the way we look at waste. And I was working with one of my best friends. I could not be more grateful of the opportunity, and I have zero regret.

It has been a year, and the project is online, so come and check it out. 

I'll be blogging here, to talk about next steps, to talk about how the recycler can be used, to relate behind the scenes stories, and hopefully, to inspire you and those you know to redefine words like trash, waste, and possible.

Imagine a more flattering pic of Janne and I, can't do it can you?

Working with the professionals: the students

We at 3DBear love to work with the professionals, and during the development of our newest app 3DBear AR we were lucky to work again with the best of the best: the students.

We have been collaborating with Kaisaniemi elementary school and few weeks back we visited with the 4th graders for few lessons.

The lesson was build up with few parts: first we went through what the augmented reality is (almost everyone knows the Pokemon Go-game). After this the students were split to pairs, and they got tablets or smartphones. The assignment was to improve the school surroundings, making it more pleasant.

When we asked the students what they like the most in their school yard, the answer was something like the swings and the climbing frames. We wanted them to think by themselves without any influence by the teacher or other authority.


Later we gathered again in the classroom where students were able to show their products to others. They had created places to sit, a climbing track and even a classroom with a bed for the courtyard. Also the passing bicycle path got a disincentive to slow down fast bikers.

Innovative and creative students also developed the assignment forward: one student made a cartoon-like story where the hero ventured in augmented reality.

Same time when the kids had a good time, they learned to use their mobile devices and social participation, working in pairs and increased their creativity.

Feedback from the students is very valuable to us and it is really fun to work with them and see how they use their ingenuity.

Think Big and Achieve Bigger, a Wonderful Journey with Eight Schools

One of our greatest enthusiasm is to work with professionals who are passionate about bringing new technologies to schools. From the start of September 2016, we have been working with Hanna Niemelä, an innovative teacher from Espoo Christian School. At the moment, Hanna is leading the Pänttäyksestä Printtaukseen Project, a project co-funded by the Finnish National Agency of Education aiming at opening up new learning paths for children who will need new technologies such as 3D modeling, AR or VR skills in their adulthood.

In total, eight schools between Oulu and Espoo are on board, they represent both private and public education sectors. Different learning modules are developed to teach the new skills and they are carried out in all of the schools by the local teachers. In a bigger picture, the project intends to set an example for schools in Finland and around the world on the applicable methods that can be adopted in teaching latest technologies to the future generation.


On September 5th, we went on a trip to Oulu Christian School with Hanna. There the local teacher Samuel Halonen was giving a course themed create your favorite board game piece. In the class, students formed groups and learned to use Tinkercad modeling program to execute their ideas and inspirations. During the design process, the students exhibited great enthusiasm and engagement, and were even more excited about presenting their final works in front of the class.

While gathering course feedback, Samuel Halonen commented: “It was not just my students that got excited about the topic, so did my co-workers who got involved. I believe everybody has obtained a share of encouragement. The lesson was clear instructed; and of course 3D modeling and printing can be simple, useful and fun.”

From the start of 3DBear’s journey, we have been working hard to help our teachers in taking the terror out of teaching new technologies. We believe that many students will take on jobs that do not exist at the moment but will emerge in the future. We are very thrilled to be an accelerator in achieving this great task.

Teacher: Save time with 3DBear!

“This formula is really important, write it down before I erase, for sure it will appear in your next exam”, I guess this ‘kind’ reminder rings a bell for people who have experienced cramming type of teaching. Back when I was a student, I cannot even recall how many times I had to blindly copy down things without knowing why. However, can we really blame our teachers for not being innovative and explanatory enough?

Many countries have started to reform education in order to get ready for the future. Finland, as a pioneer in education has already announced a new curriculum for K-12 education last year. The new curriculum attaches a lot of attention to phenomenon-based learning and multidisciplinary subjects. As the propellers of the new education, the Finnish teachers will have to learn new skills such as coding or 3D modeling, then plan a proper course to teach their students. Even for experienced teachers, the task is never easy considering the constrain in time and their knowledge towards the field of engineering and technology. Take teaching 3D printing as an example, for primary school kids, to learn the definition of 3D printing is boring yet to 3D design an object is fascinating, but will they be able to maintain their interests once the design process becomes complicated and patience-consuming? Would it be possible to teach 3D print a fidget spinner rather than a dull husky figurine? Or how to balance between engaging learning content and standardized curriculum? Good lesson planning indeed takes a lot of time and effort, especially when teachers have to organized classes that are new to them.

In this sense, wouldn’t it be awesome to have verified and ready-to-use learning modules at your disposal? And this is what 3DBear is developing at the moment. Despite there are plenty of educational apps that teach advanced technologies, but what makes 3DBear standout lays in our well-orchestrated learning modules. Because we believe in the power of technology-enhanced learning, we are aware of the struggles in teaching new technologies and we would like to make our teachers’ job easier and enjoyable.
