Slicing modular machines


Modular machines
One big task of Precious Plastic is developing machines that are more modular. Each machine will be divided in different modules/compartments/bloks *haven’t found the best word for it yet. We’re talking about parts like power supply, nozzle,  electronics, gearing etc. They are defined on which modules might be relevant to upgrade , customize in the future and where is the best place to connect them.. This is something we are defining right now, if you have any suggestions let us know!

Meet Kees, the machine builder

keesendaveOver the last month i’ve looking into all the submissions i’ve gathered from the previous post. – I was amazed by all the people that wanted to contribute to the project. After lots of spitting, thinking and skyping I selected Kees; a 53 year old unemployed machine builder from the Netherlands. He will be starting this week developing the machines and sharing updates in the forums. Below you can read more about him.

“My name is Kees 53 years old, 2 sons 24 en 26 and since last Sept. a proud grandfather of a girls-twin.”

€10.000 for open source development





had been working on machines to recycle plastic for a while, when soon after my other project Phonebloks exploded on the internet and Precious Plastic was set on hold. However, I still think this project has a huge potential and I am really keen on pushing it forward. Ihave a workshop, tools and materials to make it happen, however not the time or knowledge to get this done myself. I need a clever machine builder! That is why I am donating my prize money I won last year to someone that is able to do this.

Alex his injection machine

Recently I met Alex from Germany, he was inspired by the injection machine and used the outline to build is own machine. He already added some improvements, used a CNC milled mold and even gave a workshop with his machine.

The goal of this project is to develop machines that can recycle plastic and share them. With the blueprints online people all over the world can start building machines. So it makes me very happy to see other people building machines to recycle plastic as well.

Read his story below to find more information about his wonderful project and check out his machine!


Unique color everytime.

New website + Blueprints


After half a year delay (due to the overwhelm of my Phonebloks project.) I finally had a chance to finished up the blueprints for Precious Plastic. Including 3D models and a brand new website!


Blueprints are coming!

2014-05-05-15.32.33Currently working on the blueprints while moving in to our new workspace. It’s chaotic but works. They will be online very soon, stay tuned!

A video to show you how the machines work!


The Full story

Plastic is one of the most precious materials on earth. It’s lightweight, strong, easy to shape and great to recycle. But it’s seen as a disposable and worthless material, it’s cheap, produced in enormous quantities and shipped all over the world. Of all the plastic we use only 10% is recycled. Mainly because the machines that produce plastic products are expensive, extremely complex and are used very efficient to keep costs low. Working with recycled plastic runs the risk of damaging/polluting machines, which might slow down their production process.

I have developed a series of machines to set up a small scale plastic workshop. The machinery is based on industry standards but designed to build yourself, easy to use and made to work with recycled plastic. You can bring your old plastic to a workshop like this, new products will be made and sold. Like a carpenter or a ceramist, it is now possible to produce plastic locally.

This project is still in progress, I will continue with this and further develop machines and  set up an online community. My goal was to share all the blueprints online by now, but due to my other project Phonebloks haven’t found the time to do this yet. But stay tuned, they will come!
