Technical field

The invention belongs to 3D and print field, relate to a kind of three primary color theory that adopts, be that three kinds of colors of red, green, blue are mixed the principle that can obtain the nearly all color of occurring in nature in the proper ratio, be mixed to form in varing proportions after different color ink by the ink of three kinds of colors of red, green, blue, the heated melting of white hot plastic material and color inks are dyed blended as colour print raw material, use heat to melt and pile up the method for forming (FDM method) 3D printing color product.

Background technology

3D prints the one that production technology belongs to quick near-net-shape increasing material manufacturing technology, its principle is by software, the three-dimensional parts sterogram of Computer Design to be resolved into some layer planes to cut into slices, print out by 3D printer, produce required parts and the member of unlike material; Because of its flexibility, personalization, the quick unlike material parts of near-net-shape production structure complexity and all many advantages of integrated member, become a kind of increasing material manufacturing technology that has development prospect, especially at integrated manufacturing system (IMS) global formation, directly produce aspect complex parts integrated member and have peculiar advantage.

Current similar 3D prints near-net-shape and increases material and manufacture manufacturing technology and be able to develop rapidly in the whole world, and tentatively the production method of commercialization mainly contains laser stereoforming method, selective laser sintering method, selective electronic bundle sintering process, heat and melts the accumulation method of forming etc.

It is to adopt Low Temperature Thermal to melt printing head that 3D printing heat is melted accumulation method of forming technology, thermoplastic macromolecule material dynamic melt-flow is deposited on to ad-hoc location by the printing path extruding of the three-dimensional objects mathematical model individual-layer data control of Computer Design, thermoplastic cooling curing, successively piles up shaped article.The 3D printer price of manufacturing due to technique is low, printed product is with low cost and simple to operate, start extensively to apply to research and development of products, model manufacturing, daily personalized consumption articles for use are produced, and will spread to fast in office and average family, 3D printer can become the standard configuration the same with plane printer.

It is generally to use monochromatic or the two kinds of monochromatic thermoplasticity such as PLA or ABS raw material printed product that common Low Temperature Thermal melts accumulation method of forming 3D printing increasing material forming product, the product printing or be pure monochrome, it is simple double-colored product, cannot realize multi-color printing produces, this is at model manufacturing, and daily personalized consumption articles for use are produced the upper very large defect that just exists.Therefore the colored 3D that, develops a kind of low cost mode prints the equipment of producing macromolecular material parts and the product demand that becomes a reality.

Summary of the invention

Melt and pile up the product that method of forming 3D prints or be pure monochrome in order to solve current heat, or be simple double-colored product, cannot realize the defect that multi-color printing is produced.The present invention has developed a kind of ink jet dyeing heat melts the colored 3D printing device of the method for forming technology of piling up.

The present invention relates to a kind of three primary color theory that adopts, red, green, blue three-color mixes the principle that can obtain the nearly all color of occurring in nature in the proper ratio, by digital control circuit and professional software control printer thermoplasticity printed material feeder and color inks supply module, and three-dimensional travelling mechanism, allow red, green, the ink of blue three-color is mixed to form (similar planar coloured ink-jet printer color production theory) after different color ink in varing proportions, the heated melting of white thermoplastic resin material and color inks are dyed blended as colour print raw material, use heat to melt and pile up the method for forming (FDM method) 3D printing color product.

The invention has the beneficial effects as follows: the equipment and technology that provides a kind of colored 3D to print, solve current heat and melted and pile up method of forming 3D printer and can only print monochromatic or double-colored shortcoming, 3D print application has been enriched in multicoloured printing.

Below in conjunction with drawings and Examples, the present invention is further described.
