In July 2016, "Geophysical Research Letters" published an article saying that Stanford University is developing a new 3D printing technology that creates a new physics for rock samples by using 3D imaging technology and 3D printing technology Model, and use 3D technology to print out the modified rock.
Modern super-strong 3D printing technology provides an unprecedented opportunity to combine the advantages of micro and macro scales through digital means and experimental means. The study, by combining remote 3D imaging technology and 3D printing technology, allows scientists to create completely new physical models of detailed digitized rocks. 3D printed rocks can help researchers better understand the changes in the rock ’s microstructure and its overall structure and properties, such as its porosity and permeability. These properties will reveal the details of the rock, such as the physical process of its formation and How liquids such as water and oil pass through them provide support for the development of these resources.
3D printing the rock also allows the pore size of the rock to be changed in the laboratory, and it is perfectly printed on this scale, thus ensuring experimental testing. The study scanned a small sample of carbonate rock in detail and then tested two different SLA3D printers (a desktop printer from Formlabs and an industrial 3D Systems ProJet printer from the University ’s Technology Improvement and Innovation Laboratory) to see if it could be The tiny hollows and channels in the rock are molded, and finally the high printing resolution is used to reproduce the pores in the rock in detail. The researchers claim that the 3D printed digital rock model helps select the most scientifically valuable samples and then bring them back to Earth.
The researchers said that with the advancement of 3D printing technology, scientists will be able to reshape the details of rock structures, and even mix different materials to construct similar natural rocks, such as the moon or Mars to obtain difficult rock samples Research.

The canvas wig head is made of 100% cork. compared with poly filled canvas head, cork canvas head is more sturdy and durable.
Professional canvas block head professionally designed according to human's head shape, have more refined appearance. You could put pins and hold wigs easily. Very easy and convenient to use, great for wig making, fixing wig making, styling and display.
The wig head base has mounting holes (about 1 inch in diameter) that match most Wig Stands or tripods on the market. The clamp stand is included in the package, please refer to the steps shown in the picture to install the clamp stand.
You can measure your head circumference by going around the head behind the ears from the nape of the neck round to the front hairline.
Cover the head with some plastic wrap before making wigs. Please put it in a dry and ventilated place. Please put it under sun once a month.
