Abstract: The current invention refers to an Additive Manufacturing system that allows the increase of the dimensions of a part to manufacture and/or increase the production volume without proportionally increasing the fabrication time, while maintaining the sub-millimetric precision and finishing quality. The system is composed of at least one upper deposition module (3), or at least one lower deposition module (4), or by their combination, both being movable and interchangeable, coplanar between them and controlled in a coordinated manner, and by at least one platform module (2) movable and interchangeable and which control is done in a coordinated manner. The main rigid frame (1) is scalable. The number of upper deposition modules (3), the number of lower deposition modules (4) and the number of platform modules (2) are configurable according to the preferences of the user.

Abstract: The present invention refers to an equipment that allows the performance of fatigue testing at ultrasonic frequencies in a multiaxial loading, more specifically biaxial. The equipment is formed by two components, the horn (1) and the specimen (5), which are coupled with each other. The horn (1) and the specimen (5) possess such geometry that their resonant frequency which, is relevant for the testing, is synchronized with the excitation frequency of the exciter, so that the whole equipment vibrates in free regime. Through its vibration mode, the horn (1) transforms the pure axial cyclic movement which it receives from the exciter into a mixed movement comprised of axial and torsional cyclic and in-phase movements. The specimen (5) possesses, synchronized at the same frequency, its first axial vibration mode and its third torsional vibration mode.
