    Abstract: The present disclosure provides methods for generating three-dimensional (3D) objects. The methods may comprise generating a green part corresponding to the 3D object. The green part may comprise a plurality of particles and reactants for conducting a self-propagating reaction. The reactants may be used to conduct a self-propagating reaction that generates heat sufficient to de-bind or pre-sinter the green part. External heat may be supplied to the green part to sinter the plurality of particles, thereby yielding the 3D object. The disclosure also provides methods for generating a 3D object using a resin. The methods may comprise using the resin to generate a green part, heating the green part at a first temperature to decompose a binder in the green part, heating the green part at a second temperature to decompose a polymeric material in the green part, and sintering the green part to yield the 3D object.

  • Patent number: 9482901
    Abstract: The present invention prevents the shaving of an alignment film caused by a columnar spacer in a liquid crystal display device of an IPS method using photo-alignment. A plinth higher than a pixel electrode is formed at a part where a columnar spacer formed over a counter substrate touches a TFT substrate. When an alignment film of a double-layered structure is applied over the pixel electrode and the plinth, the thickness of the alignment film over the plinth reduces by a leveling effect. When photo-alignment is applied in the state, a photodegraded upper alignment film over the plinth disappears and a lower alignment film having a high mechanical strength remains. As a result, it is possible to prevent the shaving of the alignment film.
