- input 3D data of the original object to the device As the three-dimensional data, there are STL (Stereo Lithography) data, VRML (Virtual Reality Modeling Language) data, PLY / ZCP data, and the like.
- STL is a standard data format for transferring data from 3D CAD to various modeling devices.
- STL data refers to a polyhedral model obtained by approximating a three-dimensional solid image with a small triangular plane (facet), and can be processed by using STL editing software.
- the STL format cannot specify colors and cannot represent the same data.
- VRML is a format for expressing a three-dimensional virtual space on the Internet (on a homepage), and is capable of expressing color data.
- PLY is a format widely used by researchers who handle polygon data, and can express color data. The specification is widely published (Dr. Greg
- ZCP is a format created by ZCorporation for its products. Based on these data, ZCorpration's system prepares the slice data necessary for modeling with the equipment, and sets the modeling position, lamination width, binder application amount, etc. necessary for modeling.
- a layer of material powder is laid on a movable stage for modeling.
- a binder composition is applied to necessary parts based on the slice data.
- the modeling stage is lowered by one layer, and the second layer
- the powder particles in the portion to which the binder composition is finally applied aggregate with each other to form a three-dimensional object.
- a solid object having a desired three-dimensional shape can be produced while performing this operation or by removing unfixed powder after the operation is completed.
- a binder composition used in the prototyping technique is one that can bind powder such as water, glue, and an adhesive.
- the three-dimensional object made by this method is a rigid three-dimensional object that reproduces only the three-dimensional shape.
- a soft three-dimensional object can be produced. This is because the composition of the present invention itself has viscosity and the like, and even when the powder is hardened, the obtained three-dimensional object has the viscosity of the composition of the present invention, so that it is soft. This is because it has a degree (softness).
- a three-dimensional object having any flexibility can be produced by appropriately determining the amount and composition of the composition of the present invention.
- the rapid prototyping technique described above may be performed manually.
- the binder composition of the present invention may be put in a thin container, a large number of sheet-like solidified powders may be prepared therein, and the sheets may be laminated.
- solidification may be performed by drying with a dryer or the like.
- the binder composition of the present invention is placed in a thin container, and the powder is put therein, solidified to form a sheet, dried and solidified, and the binder composition of the present invention is stacked on the dried sheet, and the powder is mixed.
- the operation of adding and further drying and solidifying may be repeated.
- the shape of each sheet to be laminated may be designed according to the shape of the three-dimensional object to be manufactured.
- the present invention also includes a technique of softening a hard three-dimensional object obtained by solidifying a powder with an adhesive or the like by a rapid prototyping technique using the binder composition.
- the composition of the composition is the same as the above-mentioned binder composition, but is referred to as a softening composition in order to express its purpose. That is, a hard three-dimensional object formed by hardening powder is impregnated with the softening composition of the present invention. Impregnation softens the solid It may be carried out by immersing it inside.
- the immersion time is not limited, and the softness may be measured over time, and the three-dimensional object may be taken out when the desired softness is reached or when the softened composition spreads all over the three-dimensional object.
- the whole plant or animal, or a part of a living body such as an organ or a tissue is produced in a state in which not only its external three-dimensional shape and internal shape and color but also its hardness are reproduced.
- the method of the present invention produces a soft three-dimensional object for a part of a living body such as an internal organ (kidney, liver, etc.), nose, ear, limb, tissue, etc.
- the three-dimensional object has an external and internal shape.
- the softened three-dimensional object has the same softness as the softness of the original three-dimensional object, and in the case of a three-dimensional object imitating a living body, it has the same softness as a living body such as muscles and internal organs. have. Therefore, the softened three-dimensional object can be used as a surgical model, a biological model for medical education, and the like.
