摘要:
The method for manufacturing large three-dimensional objects of the present invention comprises the following steps: obtaining a three-dimensional shape data for a three-dimensional target object; converting the three-dimensional shape data into a size needed for manufacturing; transforming the size-converted data into a “shell” data (i.e., data of a hallow target object having a cavity therein); dividing the “shell” data into shell segments of such a size that can be manufactured by a rapid prototyping apparatus; prototyping each of the “shell” segments by a rapid prototyping apparatus to manufacture each of prototyped parts; assembling the prototyped parts to produce a prototype of the target three-dimensional shape object.
摘要:
A method of manufacturing a lower panel for a plasma display panel using X-rays which includes preparing a base substrate; forming a barrier rib material layer on the base substrate; defining barrier rib patterns by scanning X-rays on the barrier rib material layer; and developing the barrier rib material layer to form barrier ribs. Fine-pitch patterning of the barrier ribs can be achieved with high precision by using X-rays.
摘要:
A method of manufacturing barrier ribs of a plasma display panel (PDP), and a method of manufacturing a lower panel for the PDP. The method of manufacturing the barrier ribs for the PDP includes: preparing a mold to shape the barrier ribs, which has a patterned surface; filling a plurality of channels formed in the mold with a barrier rib material, to form barrier ribs; and compression bonding a dielectric sheet to the barrier ribs in the mold. Using a molding process, a barrier rib pattern having a desired shape can be precisely formed, and an electrode burying layer with a uniform thickness can be obtained.
