TL;DR: In this paper, the authors quantify the ultimate tensile strength and nominal strain at break of printed parts made from polylactic acid (PLA) with a Replicating Rapid prototyper (Rep-Rap) 3D printer, by varying three important process parameters: layer thickness, infill orientation and the number of shell perimeters.

TL;DR: In this paper, a first set of specimens was printed with virgin and recycled polylactic acid (PLA) and mechanically tested and the obtained results suggested that 3D printing with recycled PLA may be a viable option.

TL;DR: In this article, the effects of some scanning factors that may affect the measurement process were analyzed by using a commercial triangulation 3D laser scanner, and the results of the tests mainly pointed out that the scanner-to-object relative orientation as well as its position within the field of view of the measurement device are the key factors mostly influencing the accuracy of measurement process.

TL;DR: The influence of resin based and lithium disilicate materials on the stress and strain distributions in adhesive class II mesio-occlusal-distal (MOD) restorations is studied using numerical finite element analysis (FEA).

TL;DR: Direct resin-based composite materials applied in multilayer techniques to large class II cavities, with or without shrinking dentin layers, produced adverse FEA stress distributions and displacements.
