The purpose of this paper is to elucidate the extent to which the mechanisms of polymer melt viscous flow and finish layer powder particle adhesion influence the top surface topographies of laser sintered polyamide (PA12) components.

Laser sintered specimens were manufactured at varying laser parameters in accordance with a full factorial design of experiments. Focus variation microscopy was used to ascertain insight into their top surface heights and peak/valley distributions. Subsequently, regression expressions were generated to model the former with respect to applied laser parameters. Auxiliary experimental analysis was also performed to validate the proposed mechanisms and statistical models.

Within the parameter range tested, this work found the root mean square (S_q) and skewness (S_sk) roughness responses of laser sintered PA12 top surfaces to be inversely related to one another, and both also principally influenced by beam spacing. Furthermore, it was demonstrated that using optimised laser parameters (to promote polymer melt dispersion) and building without finish layers (to avert subsequent powder particle adhesion) reduced the mean S_q roughness of resultant topographies by 30.8% and 47.9% relative to standard laser sintered PA12 top surfaces, respectively.

The scope to which laser sintered PA12 top surfaces can be modified was highlighted.

This research demonstrated the impact the mechanisms of polymer melt viscous flow and finish layer powder particle adhesion have on laser sintered PA12 top surfaces.

This article explores the cultural politics of civic pride through Hull's year as UK City of Culture (UKCoC) in 2017. It unpicks some of the socio-political meanings and values of civic pride in Hull and critiques the ways in which pride, as an indicator of identity and belonging, was mobilised by UKCoC organisers, funders and city leaders. It argues for more nuanced and critical approaches to the consideration and evaluation of pride through cultural mega events (CMEs) that can take account of pride's multiple forms, meanings and temporalities.

A multidimensional, mixed methods approach is taken, incorporating the critical analysis of Hull2017 promotional materials and events and original interviews with a range of stakeholders.

The desire for socio-economic change and renewed identity has dominated Hull's post-industrial sense of self and is often expressed through the language of pride. This article argues that UKCoC organisers, cognisant of this, crafted and tightly controlled a singular pride narrative to create the feeling of change and legitimise the entrepreneurial re-branding of the city. At the same time, UKCoC organisers overlooked the opportunity to engage with and potentially reactivate the political culture of Hull, which like other “left behind” or “structurally disadvantaged” places, is becoming increasingly anti-political.

Through the case study of a relatively unresearched and under-represented city, this paper contributes to cultural policy literatures concerned with critically assessing the benefits and shortcomings of Cultural Mega Events and to a more specific field concerning Cities of Culture and the political cultures of their host cities. This paper also contributes to an emerging literature on the centrality of pride through the UK's post-Brexit Levelling Up agenda, suggesting that pride in place is becoming figured as a “universal theme” of the neoliberal city script.
