TL;DR: In this paper, an overview over laser-based additive manufacturing with comments on the main steps necessary to build parts to introduce the complexity of the whole process chain is presented. But despite good sales of AM machines, there are still several challenges hindering a broad economic use of AM.

TL;DR: The state of the art in scientific research concerning tailored blanks can be found in this article, where the authors present the potentials of the technology and chances for further scientific investigations.

TL;DR: In this article, the flow behavior of the steel 22MnB5 in the austenitic state has been investigated by conductive, hot tensile tests with a Gleeble 1500 system dependent on the time-temperature characteristic of the hot stamping process.

TL;DR: In this article, the authors define a new class of sheet-bulk metal forming processes, give an overview of the existing processes belonging to this class, highlight the tooling aspects as well as the resulting product properties and present a short summary of the relevant work that has been done towards modeling and simulation.

TL;DR: In this paper, the authors give an overview of these efforts substituting environmentally hazardous lubricants in cold, warm and hot forging as well as sheet forming and punching/blanking by new, less harmful lubricants and furthermore describe other measures directed towards the same goal such as development of anti-seizure tool materials and coatings and application of structured workpiece and tool surfaces.
