（4）Relic is Nian Jie with model
Model after printing can carry out assembled test after being surface-treated with corresponding relic.Air bladder or pig are used after trimming
The glue that skin etc. boils is to relic and repairs part and is adhesively fixed, and natural gum main component is collagen, Nantural non-toxic and viscous
Degree is high.
The manufacturing process of fish glue：
Fat glue was always to use two kinds of pig fat glue or fish glue in the past, or was used alone, or was shared.With the hair of Chemical Engineering Technology
Exhibition, it is alternative now with many chemical glues, both glue boil and use during, it is cumbersome, but Nantural non-toxic
Binding agent.
1. season and sorting.Fish glue boils season, and it is preferably the time after the Frost's Descent to have a kind of saying, because this period
Air is cold and dries, and is advantageous to the condensation and drying of glue.Weather too hot glue is non-condensing, does also slow and apt to deteriorate smelly
It is mouldy.Sorting will be particular about, the past coastal area typically with rice air bladder come glue, viscosity is especially big, but rice fish is rare now, price
Costliness, general glue all use rheum officinale air bladder, and effect is not also poor.Choose relatively good, the bigger yellow croaker fish glue parched of quality（This table
Bright large yellow croaker growth is for years, if small rate of gum output is low, viscosity is not strong）It is standby.
2. it is soaked.The air bladder chosen is placed in clear water and steeped, after feeling like jelly, fritter as small as possible is cut into scissors, after
Continuous bubble 24 hours.
3. pot steaming.Fish glue body to be waited becomes rotten soft, when entire body is turned white, is pulled out in water, collects together solid carbon dioxide part and is placed in plate, is put into
Pressure cooker（Or general food steamer）In steam, about three, 40 minutes, take one piece to bite with the teeth, feel it is glutinous it is soft, stick to one's teeth.
4. pound glue.Glue is taken out, is immediately placed in garlic mortar and smashes for a long time（It is generally placed upon on chopping block and is pounded with hammer in the past）, smash
Time longer fish glue it is more broken better, such rate of gum output is high.As pectin is more dry, appropriate boiling water can be added, continues to smash.
5. boil.The glue accomplished fluently is taken out, is placed on gauze, wraps.Boiled water with iron pan, be placed in pot and put with iron bowl
Appropriate boiling water, gauze is placed in iron bowl, side foam can be repeated while extruding, until glue is all penetrated into bowl.
Remaining fish glue slag can dry to be used next time again.
6. dry.Glue in bowl is poured into big and flat utensil, glue can condense into relatively thin jelly in utensil bottom
Shape thing, is opened after a while, is torn into fritter, is placed on ventilation drying, until moisture all volatilizees, colloid is dry and hard, you can
It is placed in closed utensil and stores, in case uses.So far, whole glue process is completed.
After 6th step is dried, preserve, if used, after soaking, then be placed in double boiler and boil, it can be used into liquid.
Glue in 5th step can be used directly, and is simply because and has added boiling water in advance, so glue is diluter, impact effect.It is remaining
Fish glue slag, it is also the same as new fish glue during next glue, since being soaked, repeat step.Why color depth is boiled
Being essentially consisted in shallow dividing, the time boiled, the color of the time longer glue typically boiled is more shallow, is also exactly the temperature of glue,
Temperature is most difficult to grasp, and general temperature is unsuitable too high.
Based on foregoing description, the present embodiment first scans remaining porcelain parameter using computer-aided three-dimensional, enters through computer
The secondary levelling of row, then secondary levelling data are transferred to 3D printer, forming technique is digitized into, by water white transparency macromolecule material
