TL;DR: In this article, tensile strength, modulus of rupture, and impact resistance were found for different layer orientations of ABS rapid prototype solid models, fabricated by a Stratasys rapid prototyping machine.

TL;DR: In this article, the room temperature tensile properties of Ti-6Al-4V alloy prepared under two different processing routes were evaluated and compared, one group of samples was prepared by conventional casting-forging-rolling into flat plates, and the other group were prepared by using Triton's Laser Free-Form Fabrication (LF3)™ processes, i.e., a laser was used to melt pre-alloyed powders of the required metallic composition as they were dropped onto a moveable substrate programmed to move in such a manner as to form a solid

TL;DR: In this paper, the effect of layer orientation on the mechanical strength and toughness of a polymer was evaluated using tensile testing and three-point bend testing, and the toughness was evaluated by Izod impact testing.

TL;DR: In this paper, the influence of varying the thermal processing parameters on the physical and mechanical properties of 7075 T6 aluminum alloy was studied and an excellent correlation was found between the tensile strength and hardness.

TL;DR: A steel molding of ASTM A681 developed a large crater while being fabricated on an electrical discharge machine as mentioned in this paper, probably caused by inadequate flushing of the dielectric/coolant.
