Making process of 3D color object

Abstract

The making process of 3D color object includes the following steps: the first establishing 3D solid model of the object in a computer and tomographing to obtain the forming information of all layers; spreading color water solution to a flat powder layer with printing nozzle under the control of computer to form first color ply; spreading powder on the first color ply and forming the second color ply similarly and adhering the second ply to the first ply to form one integral; and so on until the last ply to make the designed 3D object. The process is fast, reliable, safe and low in cost, and can make 3D color object with complicated shape. All the formed materials are non-toxic, so that the making process may be completed in office condition.

Description

Technical field [0001] The invention relates to a forming method for rapidly producing a colored three-dimensional object by adopting a printing method, in particular to a method for producing a colored three-dimensional object. Background technique [0002] Rapid prototyping technology is a rapid production tool from computer three-dimensional entities to physical entities. It is suitable for the production of prototypes and small batches of functional parts. The materials of the produced parts can be ceramic materials, metal materials, paper, photosensitive resins and other materials. The more commonly used processes of rapid prototyping technology include light curing process, selective laser sintering, fuse deposition production, laminated solid production and three-dimensional printing. [0003] The above processes can produce complex three-dimensional objects, but the three-dimensional entities produced are all monochrome. For example, some companies h...

Problems solved by technology

[0003] The above several processes can make complex three-dimensional objects, but the three-dimensional entities produced are all monochromatic

For example, some companies have developed several different-color molding materials that can be used for fused filament deposition, but each three-dimensional object can only be monochrome, and it is impossible to produce colored three-dimensional objects.

In this way, for the conceptual design and appearance design of the product, the product lacks color expressiveness.

[0004] In addition, the current photocuring process, selective laser sintering, fused filament deposition production, laminated solid production and 3D printing are all slow in production speed and high in production cost, which is not conducive to the reduction of product development costs
