TL;DR: In this paper, the feasibility and dimensional accuracy of two rapid casting (RC) solutions based on 3D printing technology were evaluated, namely investment casting starting from 3D printed starch patterns and the ZCast process for the production of cavities for light-alloys castings.

TL;DR: In this article, a new technique of checking the machine quality of a Rapid Prototyping (RP) workpiece according to the ANSI-ISO standards is presented, and the surface of RP model were observed by SEM microscope.

TL;DR: In this article, a post-treatment of green metal parts (AISI 420 metal powder with 2-3% polymeric binder) was used for near-net-shape and net-shape manufacturing.

TL;DR: For the first time, a homogeneous microstructure comprised of an intricate network of thin ε (hcp)-lamellae distributed inside a γ (fcc) phase was observed, showing a hardness value remarkably higher than those commonly obtained for the same cast or wrought alloys.

TL;DR: Bonacini et al. as discussed by the authors showed that process parameters optimisation depends only on the geometrical configuration and not on the deposited alloy, which suggests the importance of an accurate design of the reciprocal positioning and movement between the torch and the part to be coated, as a function of the deposition geometry.
