Recyclebot Explained

A recyclebot (or RecycleBot) is an open-source hardware device for converting waste plastic into filament for open-source 3D printers like the RepRap.[1] Making DIY 3D printer filament at home is both less costly and better for the environment than purchasing conventional 3D printer filament.[2] [3] [4] In following the RepRap tradition there are recyclebot designs that use mostly 3-D printable parts.[5]

Motivation and benefits

RepRap 3D printers have been shown to reduce costs for consumers by offsetting purchases that can be printed.[6] [7] [8] [9] The RepRap's plastic feedstock is one area where cost can still be reduced. In 2014, professor Joshua Pearce pointed out that "Filament is retailing for between $36 and $50 a kilogram and you can produce your own filament for 10 cents a kilogram if you use recycled plastic"[10] The device can thus further enhance RepRap affordability by reducing operating costs.[11] In addition, by reducing prosumers' reliance on purchased products, the RepRap and the recyclebot have made it feasible for 3D printing to be used for small-scale manufacturing to aid sustainable development.[12] [13] It has been postulated that recycled filament production could also offer an alternative income source by the Ethical Filament Foundation[14] [15] or as a form of "fair trade filament".[16] It has also been shown to improve the energy payback time of even known green energy technologies like solar photovoltaics.[17]

Technology

The RecycleBot is an open-source hardware project – thus its plans are freely available on the Internet.

History

The history of the RecycleBot was largely derived from the work on the RepRap Wiki under GNU Free Documentation License1.2.[20]

The first recyclebot was developed by students at Victoria University of Wellington, New Zealand.[21] [22] [23] This design was a proof of concept and was hand-powered, and so had a small ecological footprint, but did not create filament of high enough quality to be useful for 3D printers. The design for the waste plastic extruder (Recyclebot v2.0 and v2.1) developed at Queen's University Canada and Michigan Tech was heavily influenced by the Web4Deb extruder, which extrudes HDPE for use as a growth medium in aquaponics.[24] This design for the recyclebot was developed, tested and published in the peer-reviewed rapid prototyping literature.[25] This device proved viable for producing 3D printing filament. The Recyclebot v2.2 is being developed by the Michigan Tech in Open Sustainability Technology Research Group.[26]

Many makers or DIY enthusiasts have made various versions of RecycleBots. The most notable is the Lyman filament extruder. Lyman, a retired engineer, won a design contest to make a low-cost 3D filament fabrication system.[27] As of 2014, there were many types of recyclebots, many of which are at the early stages of commercialization. Recyclebot technology has been applied to hangprinters to allow for fused particle fabrication of large prints without first having to form filament.[28]

Futurist speculation

Jeremy Rifkin has hypothesized that such recycling with recyclebots and distributed production with 3D printing will lead to a zero marginal cost society.[29] The science-fiction author, Bruce Sterling wondered in Wired if recyclebots and 3D printers might be used to turn waste into guns.[30] Recyclebots can provide a new method of recycling.[31]
