What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

About

collected plastic waste ready for crushing.
collected plastic waste ready for crushing.

Plastic waste is one of the biggest problems we currently face when it comes to environmental issues. Several projects already came up with a solution to collect this waste, for example with specific nets that extract huge plastic islands from the oceans. However, the question remains what will be done with the plastic waste. This is where we found the perfect solution. 3D printed furniture of recycled plastic waste!

Sandhelden is a young tech-startup from Augsburg/Germany. We are a diversified team of designers and engineers with a vision to set new standards in recycling processes by using our self developed binder-based 3D printing technology (Binder Jetting). Our goal is to produce interior products by crushing plastic waste into powder and to use this as a 3D printing material.

Throughout various media campaigns, we had some amazing feedback on how we could improve our recycling idea and help to turn it into reality. This, in turn, will result in a better product for our customers and followers.

The Recycling Process: 5 Steps from Waste to Powder to Printing

1. Collecting the waste: The plastic waste is separated and classified in categories like thickness, colour and differences of their characteristics - technical and standard plastics. 

2. Crushing process: The separated waste is crushed into powder during three steps. First, the waste is shredded in 5mm parts. Second, the parts are frozen in order to be crushed into poweder. Finally, the powder is sifted to gain a consistent grain size for the 3D printing.

3. Mixing the powder: Our products are as individual as our material itself. It can be produced by 100% recycled plastic or can be mixed with other materials like sand, ceramics or carbon. 

4. Production: The fine powder with thickness of the corns by 60µ is now ready for our 3D printing process. Every individual product is printed layer by layer in our 3D printer.

5. Recycling: Every product has a certain time span in which it can or will be used. Instead of just throwing it away we want to ensure that these products regain a new life by bringing it back to our recycling process. From here it will start all over again with the first step.

With your help we can turn this idea into reality. Let´s be part of something truly amazing!

Risks and challenges

We need your support for realizing this project. The main problem is to get enough recycled powder for the 3D printing process. This is due to the fact that our system needs around one ton of powder in order to print one whole "printing box". To reach this critical mass we need your help.
