Why PET?

PET is a versatile material, which is why it's one of the most used types of plastic in the world.

It's being increasingly used in the 3D printing industry because of its ease of use and strength.

Better for the Environment

Reflow is made from recycled plastic, using little virgin petroleum. We remove bottle waste from the environment.

Strong as ABS, Easy as PLA

PET is a stiff and lightweight material, which makes it strong and impact-resistant. It’s a stable and harmless plastic.

More for Less

Reflow has similar properties as virgin PET filament, but it costs less. Its features include consistent diameter, flexible strength, easy adhesion.

Fewer Fumes

Beyond used for food containers, PET produces minimal odors or fumes when printed.

Easy to Identify

Because of it's primary use in plastic bottles, PET is easy for collectors to identify, ensuring that our filament is made from 100% PET.

Why do we do it?

By sourcing plastic and producing the filament in developing regions, we can increase the value of gathered plastic by up to 20 times. We reinvest part of our profits into local manufacturing projects so we grow together.

Our mission is to significantly improve the lives of the nearly 40 million waste collectors worldwide who earn less than $2 a day and to create a global, socially responsible 3D printing community.

Reflow recognises that in order for this filament to make a difference, we need to be 100% transparent, which is why we invite you to read our Transparency Page
