3D printing technology is increasingly being used to aid repair, especially in the creation of spare parts. We invited Bas Flipsen and Julieta Bolaños Arriola to talk about their work in the field and how 3D printing can help solve the e-waste crisis.
3D Printing Industry asked EOS, Spare Parts 3D, DiManEx, Ricoh 3D and Link3D for their thoughts on how 3D printed spare parts could help consumer appliance manufacturers adhere to the legislation, while avoiding large physical stocks of replacement parts and subsequent incurring costs.
The rapid technical evolution of additive manufacturing (AM) enables a new path to a circular economy using distributed recycling and production. This concept of Distributed Recycling via Additive Manufacturing (DRAM) is related to the use of recycled materials by means of mechanical recycling process in the 3D printing process chain. This paper aims to examine the current advances on thermoplastic recycling processes via additive manufacturing technologies. After proposing a closed recycling global chain for DRAM, a systematic literature review including 92 papers from 2009 to 2019 was performed using the scopus, web of science and springer databases. This work examines main topics from six stages (recovery, preparation, compounding, feedstock, printing, quality) of the proposed DRAM chain. The results suggested that few works have been done for the recovery and preparation stages, while a great progress has already been done for the other stages in order to validate the technical feasibility, environmental impact, and economic viability. Potential research paths in the pre-treatment of recycled material at local level and printing chain phases were identified in order to connect the development of DRAM with the circular economy ambition at micro, meso and macro level. The development of each stage proposed using the open source approach is a relevant path to scale DRAM to reach the full technical potential as a centerpiece of the circular economy.
La extrusora de polímeros cumple la función de transformar partículas de polímeros en una sección continua de material. Se propone utilizar polipropileno reciclado de las tapas plásticas de botellas, para ser transformado a un filamento usado por las impresoras 3d. Es decir, transformar un desecho a filamento y el filamento a cualquier cosa que queramos imprimir. En esta etapa del proyecto el polipropileno triturado lo encontraremos en empresas que se encargan de triturarlo y lavarlo.
Dundee – 3D printer being used to produce items to aid in storytelling for those with additional needs, also for producing items for reminiscence packs etc. Launched 20th May 2014, becoming the first 3D printer in a public library in the UK, bearing Exeter by two days.
