How to Measure Quality of Affordable 3D Printing: Cultivating Quantitative Index in the User Community

Rapid, continuous additive manufacturing by volumetric polymerization inhibition patterning

“…The UV and blue wavelengths used by the two-color AM system are highlighted by the violet and blue vertical bars, respectively. ( F ) Solid block M (left) and tug boat [model detailed in ( 31 )] (right) printed using the two-color photopolymerization/photoinhibition stereolithography system at 500 and 375 mm/hour, respectively. ( G ) The polymerization inhibition volume thickness is affected by varying intensity ratios of the incident irradiation wavelengths ( I UV,0 / I blue,0 ) and resin absorbance ( h UV ).…”

Morphometric Analysis of Trail Network and Tourist Vulnerability in a Highly Frequented Protected Area

“…The five algorithms have been applied using the free software QGIS (ver. 3.20), Whitebox (v2.1.0), and SAGA-GIS (: (i) TRI terrain ruggedness index, which gives the variance of elevation change across the 3 × 3 cells [78]; (ii) Vector Roughness Measure (VRM), which combines the variability of slope and aspect to quantify terrain ruggedness [79]; (iii) ANVAD (Angular Normal Vector Angular Deviation), which gives a measure of the surface roughness quantify-ing the angular deviations in the direction of the normal vector [80]; (iv) slope gradient; (v) gradient along the trail. In order to estimate the hiking frequentation and the tourist vulnerability, data have been analyzed regarding the number of presences within the park and the number of rescue operations, in the years 2010-2021.…”

Thingiverse: review and analysis of available files

“…The paper by Ko et al (2016) discusses the quality of 3D printer hardware for consumers. In their research, the authors reference the Thingiverse platform as a community where users share and discuss quality assessments for various 3D printers.…”
