Problems solved by technology

[0004] Using 3D printing technology to print the restored appearance is undoubtedly the fastest way, but the current problem encountered is that the price of 3D printing materials is too high, which increases the cost of skull restoration; another problem is that the skull is restored. The face of the person has a high requirement for printing fineness, which is convenient for printing a lifelike person's head.

Embodiment 1

[0021] Take 80 parts by weight of gypsum powder, 25 parts of phenolic resin, 10 parts of nano-calcium carbonate, 6 parts of nano-manganous oxide, 3 parts of polyisocyanate, 5 parts of reinforcing agent and 3 parts of stabilizer. The stabilizer is stabilizer 1096, and the reinforcing agent is graphite.

[0022] First, add gypsum powder, phenolic resin, nano-calcium carbonate, nano-manganese oxide, and polyisocyanate into the high-speed mixer, and mix at a speed of 650rpm for 20 minutes;

[0023] Then, add the obtained raw materials into the mixer, and add stabilizer and reinforcing agent at the same time, control the temperature in the mixer at 90°C, and mix at a speed of 200rpm for 10 minutes;

[0024] Finally, the mixed raw materials are added to a twin-screw extruder for melt extrusion, and the extruded material is cooled and then added to a pulverizer to be pulverized into fine powder.

Embodiment 2

[0026] Take 120 parts by weight of gypsum powder, 35 parts of phenolic resin, 16 parts of nano-calcium carbonate, 12 parts of nano-manganese oxide, 8 parts of polyisocyanate, 10 parts of reinforcing agent, and 8 parts of stabilizer. The stabilizer is stabilizer 1096, and the reinforcing agent is graphite.

[0027] First, add gypsum powder, phenolic resin, nano-calcium carbonate, nano-manganese oxide, and polyisocyanate into the high-speed mixer, and mix at a speed of 750rpm for 30 minutes;

[0028] Then, add the obtained raw materials into the mixer, and add stabilizer and reinforcing agent at the same time, control the temperature in the mixer at 110 ° C, and mix at a speed of 250 rpm for 20 minutes;

[0029] Finally, the mixed raw materials are added to a twin-screw extruder for melt extrusion, and the extruded material is cooled and then added to a pulverizer to be pulverized into fine powder.

Embodiment 3

[0031] Take 100 parts by weight of gypsum powder, 30 parts of phenolic resin, 13 parts of nano-calcium carbonate, 9 parts of nano-manganese oxide, 5 parts of polyisocyanate, 8 parts of reinforcing agent and 6 parts of stabilizer. The stabilizer is stabilizer 1096, and the reinforcing agent is graphite.

[0032] First, add gypsum powder, phenolic resin, nano-calcium carbonate, nano-manganese oxide, and polyisocyanate into the high-speed mixer, and mix at a speed of 700rpm for 25 minutes;

[0033] Then, add the obtained raw materials into the mixer, and add the stabilizer and reinforcing agent at the same time, the temperature in the mixer is controlled at 100 ° C, and mixed at a speed of 225 rpm for 15 minutes;

[0034] Finally, the mixed raw materials are added to a twin-screw extruder for melt extrusion, and the extruded material is cooled and then added to a pulverizer to be pulverized into fine powder.

Abstract

The invention discloses a 3D printing material for archeology skull restoration. The 3D printing material for archeology skull restoration is prepared from the following raw materials in parts by weight: 80 to 120 parts of gypsum powder, 25 to 35 parts of phenolic resin, 10 to 16 parts of nanometer calcium carbonate, 6 to 12 parts of nanometer manganous oxide, 3 to 8 parts of polyisocyanate, 5 to 10 parts of reinforcing agents and 3 to 8 parts of stabilizing agents. The 3D printing material for archeology skull restoration has the advantages that the price is relatively low; the used materials are mostly ordinary materials; the 3D printing cost is reduced. The fineness of restoration products printed and formed by using the material is high; the face feature of a person can be favorably restored at a high standard; the appearance luster degree of the printed and formed finished product is high; the weathering-resistant capability is high; the service life of the restoration product is long.

Description

technical field [0001] The invention relates to a 3D printing material, more precisely, a 3D printing material used for archaeological skull restoration. Background technique [0002] Skull restoration technology, that is, three-dimensional craniofacial identification technology, belongs to the frontier topic in the field of international forensic individual identification, and is widely used in archaeology. China's three-dimensional craniofacial identification technology is currently at the international leading level. The system can perform three-dimensional scanning of the skull, measure the thickness of soft tissue, perform three-dimensional reconstruction, and restore the appearance. Reconstruct a digital image similar to the victim's face before life, and through three-dimensional craniofacial identification, finally determine the source of the unknown skull. [0003] 3D printing technology is based on the computer three-dimensional design model, through the softwa...
