A method of forming an implant having a porous tissue ingrowth structure and a bearing support structure. The method includes depositing a first layer of a metal powder onto a substrate, scanning a laser beam over the powder so as to sinter the metal powder at predetermined locations, depositing at least one layer of the metal powder onto the first layer and repeating the scanning of the laser beam.

Disclosed herein are methods, apparatus, and systems for providing an optical beam delivery system, comprising an optical fiber including a first length of fiber comprising a first RIP formed to enable, at least in part, modification of one or more beam characteristics of an optical beam by a perturbation assembly arranged to modify the one or more beam characteristics, the perturbation assembly coupled to the first length of fiber or integral with the first length of fiber, or a combination thereof and a second length of fiber coupled to the first length of fiber and having a second RIP formed to preserve at least a portion of the one or more beam characteristics of the optical beam modified by the perturbation assembly within one or more first confinement regions. The optical beam delivery system may include an optical system coupled to the second length of fiber including one or more free-space optics configured to receive and transmit an optical beam comprising the modified one or more beam characteristics.

The present application provides a method for preparing a metal foam. The present application provides a method which can freely control characteristics, such as pore size and porosity, of the metal foam, prepare the metal foam in the form of films or sheets which have conventionally been difficult to produce, particularly the form of thin films or sheets as well, and prepare a metal foam having excellent other physical properties such as mechanical strength. According to one example of the present application, it is also possible to efficiently form a structure in which the metal foams as above are integrated with good adhesive force on a metal base material.

Devices that use additively-manufactured connectible unit cells are described in which each unit cell comprises materials and voids. The materials occupy a certain volume of the unit cell with the voids occupying the balance of the volume. The unit cells form a lattice structure, which exhibits smooth transitions between each of the adjacent unit cells. The lattice structure exhibits periodicity along one (1), two (2), or all three (3) dimensions. The materials have a thickness that is a function of the material location within the device.
