<p>In this study we aim to investigate recycling of waste plastics products into filaments for use in a typical FDM 3D printing system. We investigate the parameters relating to control of the filament thickness to a variety of different plastic types, which include HDPE and ABS. Following filament generation, parameters were investigated to optimise the print parameters to produce a variety of demonstration models, which test the print resolution. Results suggest that the proposed supply chain can allow for highly repeatable ABS and HDPE filament generation with a diameter of 1.74 ± 0.1mm and 1.65 ± 0.1mm respectively. Ultimately, the production of usable filaments can provide a viable means of consuming waste plastics and reducing the burden of increased landfill. </p>

Stigma related to mental health and its treatment can thwart help-seeking. The current study assessed college athletes’ personal and perceived public mental illness stigma and compared this to nonathlete students. Athletes (N = 304) were National Collegiate Athletic Association (NCAA) Division I athletes representing 16 teams. Results indicated that athletes reported greater perceived public stigma than personal stigma. Athletes reported significantly higher levels of stigma compared to nonathlete peers (n = 103). Accordingly, athletes may benefit from education that can reduce the stigma of mental illness and reduce prejudices toward those who are seeking treatment. Additional implications for improving access to care are discussed.

<p>3D printing and Building Information Modelling (BIM) are two technologies that have become increasingly popular and changed a wide variety of applications in a significant manner. 3D printing enables the design, prototyping and manufacture of items that were previously impossible or infeasible to do. Similarly, BIM is changing the way building and civil infrastructure projects are conceived, designed, delivered and maintained with a push towards a digital, wholly collaborative construction environment.</p><p>This paper examines how 3D printing and BIM can be used in a complimentary manner to help visualise and communicate important aspects of a project to the relevant stakeholders and personnel involved. By using the BIM model that has been developed for a specific project and segmenting key components of this model we can then use 3D printers to create a scaled model of the job and educate the concerned parties in the construction methodology, main risk areas, and ongoing concerns for maintenance and end-of-life deconstruction. </p>
