It’s not news to anyone that consumers are becoming more eco-conscious and demanding environmentally friendly products. As a result, companies are being forced to meet these demands. Of course, the 3D printing community is no different.

Slowly, manufacturers are providing more sustainable filament options – for example, recyclable or cardboard spools. However, for Richard Horne, aka RichRap3D, this wasn’t enough.

Essentially, this concept is a material refill system. Horne’s idea is that you would print yourself a MasterSpool and then simply buy the filament refills from manufacturers which can be packaged in the bare minimum plastic.

This avoids the heavy 260 grams of extra plastic used only for the spool. Horne’s idea would also reduce the weight needed to be shipped and hopefully save you a few dollars too.
