    摘要： Disclosed herein is a hot tool which machines a workpiece made of foam material. The hot tool of the present invention includes a motor, a rotary unit which is coupled to the motor, and an electrode terminal which is connected to an outside power supply and contacts an electrode of the rotary unit. The hot tool further includes a heating body which is coupled to the rotary unit so that the heating body is heated by electric current supplied through the electrode terminal, with a spiral groove formed in a circumferential outer surface of the heating body. The hot tool further includes a polymer storage case which is provided at an upper position on the circumferential outer surface of the heating body, so that molten polymer that moves along the spiral groove is stored in the polymer storage case. Therefore, the hot tool of the present invention has increased machining accuracy and prevents a workshop from becoming messy due to molten polymer.

    摘要： A heating tool for shaping a soft material is provided. The heating tool is mounted to a predetermined position of a shaping apparatus and connected to a power source provided at a predetermined position of the shaping apparatus to melt and shape the soft material under a high temperature. The heating tool includes shaping parts which come in contact with the soft material to melt the soft material, and heating parts which are provided to be in non-contact with the soft material. The heating parts collect the molten soft material and thermally decompose the molten soft material. The heating tool enables a surface of the soft material to be perfectly thermally decomposed. Thus, the present invention prevents the soft material from being undesirably deformed, due to the molten material remaining after a shaping process.

    摘要： The present invention provides a method, which infiltrates super-heated material between preheated powder particles and therefore minimizes heat deformation and increases measurement accuracy. A rapid prototyping apparatus in accordance with the present invention comprises powder material spreading means 10, dispensing infiltration material means 20, laser beam scanning means 30, and control means. The powder material spreading means spread out powders 61 on the surface of platform 52 uniformly while moving along the X axis. The powders are the main material of desired products. The dispensing infiltration material means dispense infiltration materials 63 while moving along three axes and the super-heated infiltration materials 64 by laser beam 43 are infiltrated between the powders selectively. The laser beam scanning means preheat the powders by laser beam 42 within the melting point of the powders and super-heat the infiltration material by laser beam 43. The control means control the powder material spreading means, the dispensing infiltration material means, and the laser beam scanning means on the basis of modeling data of the desired products.

    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 constructing surface element layers for improving boundary shape of a hexahedral mesh used in finite element analysis comprises constructing a core mesh by superimposing a regular grid on a region to be meshed and removing external elements and external nodes of the region to be meshed; amending the core mesh to have a boundary shape similar to that of the region to be meshed by repositioning nodes on the boundary of the core mesh; constructing imaginary thin surface element layers on a boundary surface of the amended core mesh; and performing a mesh smoothing on the imaginary thin surface element layers.
