Today on Adafruit’s weekly live 3D Hangouts, we will be sharing a guide and video featuring DIY 3D printing filament and print recycling. Here’s a quick roundup of other DIY 3D Filament stories that caught our interest to whet your appetite!
While Recyclebot is also the generic term for machines that recycle printed parts, it is also the name of a RepRap community project, now maintained and hosted by Michigan Tech‘s Open Sustainability Technology Lab. This project is still under development, and there are requests from professor Joshua Pearce seeking graduate students interested in related projects. (See Pearce’s and collaborators’ paper on this topic from 2013)
…A low-cost, open source, self-replicating rapid prototyper (RepRap) has been developed, which greatly expands the potential user base of rapid prototypers. The operating cost of the RepRap can be further reduced using waste polymers as feedstock. Centralized recycling of polymers is often uneconomic and energy intensive due to transportation embodied energy. This paper provides a proof of concept for high-value recycling of waste polymers at distributed creation sites.
…Previous designs of waste plastic extruders (also known as RecycleBots) were evaluated using a weighted evaluation matrix. An updated design was completed and the description and analysis of the design is presented including component summary, testing procedures, a basic life cycle analysis and extrusion results. The filament was tested for consistency of density and diameter while quantifying electricity consumption.
…Filament was successfully extruded at an average rate of 90 mm/min and used to print parts. The filament averaged 2.805±0.003mm diameter with 87% of samples between 2.540± 0.003mm and 3.081± 0.003mm. The average mass was 0.564 ± 0.001 g/100mm length. Energy use was 0.06 kWh/m.
The success of the Recyclebot further reduces RepRap operating costs, which enables distributed in-home, value added, plastic recycling. This has implications for municipal waste management programs as in-home recycling could reduce cost and greenhouse gas emissions associated with waste collection and transportation as well as the environmental impact of manufacturing custom plastic parts.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
