TL;DR: In this article, a digital light processing (DLP) system was developed for the fabrication of complex technical ceramics, requiring high levels of detail and accuracy, and the feasibility to control the dimensional overgrowth to gain resolution below the native resolution of the light engine was evaluated.

TL;DR: The aim of this study was to determine the fracture toughness of denture base resins and to compare the results with impact strength measurements, and the WOF value appeared to be the test that allowed a clear differentiation between the products.

TL;DR: In this paper, a method and a device for processing a light-polymerizable material (5, 55) for building up an object (27) in layers, using a lithography-based generative manufacture having a construction platform (12), a projecting exposure unit (10, 60) that can be controlled for locally selected exposing of a surface on the construction platform to an intensity pattern having a prescribed shape, and a control unit (11, 61) prepared for polymerizing overlapping layers (28) in successive exposure steps, each with a prescribed geometry, by controlling the projecting

TL;DR: Slip based on a polyreactive binder, polymerization initiator and filler, which contains (A) 5-65 wt.-% polymerizable binder and (B) 0.001-1.0 wt −% photoinitiator and (C) 35-90 wt−% surface modified ceramic and/or glass ceramic particles relative to the overall mass of the slip as discussed by the authors.

TL;DR: In this paper, a method and a device for processing light-polymerizable material for the assembly of a mold, utilizing a lithography-based generative manufacturing technique, were presented.
