Description
Technical field
The present invention relates to 3D printing field of material preparation, in particular to a kind of 3D printing flour model material and preparation method thereof.
Background technique
Dough model is commonly called as dough model, is commonly called as face flower, gift steamed bun, flower cake, pinches dough figurine, is derived from Shandong, Shanxi, national in Pekinese
Between one of traditional art.It is to call in the pigment and preservative of different color using flour as major ingredient in conventional processes, with finger and
Simple tool --- pocket knife, small double-edged fine-toothed comb, bamboo needle etc. are moulded various vivid after the skill and technique such as rubbing, pinching, rub, roll, press, seize, choose with the hands
Vivid such as raw statue.According to Historical Data Data About, Chinese dough model art just had literature record early in Han dynasty, by succession in thousands of years
And operation, it is that history is of long standing and well established, is a part of Chinese culture and folk art already.Be also research history, archaeology,
The very important money section in kind of folk custom, sculpture, aesthetics.For kneading style, Yellow River basin is simple and unsophisticated, thick expand, is bold and unconstrained, deep；
The Yangtze river basin is careful, graceful, exquisite.This civil novelty that thousands of years are spread in China, because in its unique culture
Contain and the form of expression, tourism, foreign trade, in terms of all there is certain value, nowadays have been cited as the immaterial text of country
Change legacy.
3D printing technique is a kind of increases material manufacturing technology, rises in 19 th century laters, it is to design mould with Computerized three-dimensional
Type is source, and by the way that software hierarchy is discrete and numerical control molding system, printed material is successively accumulated to bonding, final superposition molding,
Produce physical product.The application field of 3D printing covers aviation, mold, medical treatment, drug, food, education etc..For printing
Material it is varied, the high molecular material used from laser sintered applied metal powder to fusion sediment is viscous from powder
Photosensitive resin ... that the binder that uses and powder are used to stereolithography apparatus is tied with the development of material technology, for
The material of 3D printing is more and more, and the research and development of new material emerge one after another, and various printing technology also reach its maturity.
Traditional dough model is to the requirement of producer's skill and technique with higher, especially a vivid fineness life-like, true to nature
The production of dough model art product with greater need for artist's many years technology study with temper, ordinary people is difficult to meet this requirement.3D printing
The features such as dough model is compared and conventional fabrication method, has and saves material, easy to operate, is meeting the same of client individual's customized demand
