Abstract
Entry-level material extrusion artefacts persistently suffer from questionable weakened end-product production quality, according to industrial standards. These limitations can be addressed by the development of improved finishing techniques that may narrow the gap between low-cost and high-end production methods in additive manufacturing. In doing so, the technology may become available to a larger spectrum of prosumers who previously were reluctant to use entry-level technology because of these limitations. This article describes the effect that acetone has as a post-production finishing technique for low-cost artefact production. Through a series of quantitative investigations, the study provides evidence that acetone reduces the tensile strength, increases polymer ductility, and significantly reduces the surface profile roughness of thermoplastics such as acrylonitrile butadiene styrene. The potential cost and waste reduction for entry-level manufactured products can then be identified.
Highlights
Entry-level material extrusion (ELME) development is experiencing a notable growth in the opensource makerspace and in the academic sphere
As recently as three years ago, insufficient data were available to provide a formal platform for referencing or citing the development of post-production finishing techniques (PPFTs) for ELME
A larger spectrum of prosumers will be able to apply this technology, using manufacturing and training facilities such as the I2P laboratories. This process, in turn, can be developed through sustainable hard-skills training programmes that address technique development. This practice could advance the ELME technology to stimulate the creation of a niche market, where previously reluctant prosumers will be able to produce entry-level AM artefacts at relatively low cost, in comparison with high-end additive manufacturing
Summary
Entry-level material extrusion (ELME) development is experiencing a notable growth in the opensource makerspace and in the academic sphere. The growth in these open creative spaces where designers, engineers, and prosumers fabricate is mainly attributed to hardware (3D printer) and software (CAD program) developments. ‘Prosumers’ have become defined as consumers of the production materials used during the fabrication of 3D printed artefacts. It is, evident that ELME is improving, there are quality limitations to the technology. As recently as three years ago, insufficient data were available to provide a formal platform for referencing or citing the development of post-production finishing techniques (PPFTs) for ELME
