After printing the world's first beef and pork in 2010, MODERMmeadw will be producing a lot of leather this year. The use of 3D printing manufactured raw leather leather no hair, no hard skin, compared with the traditional process, it only needs the tanning process is simple, which makes the chemical raw materials is greatly reduced.
3D printing is also called rapid prototyping, material manufacturing and rapid manufacturing. Simply put, it is processed by layers according to the idea of numerical integration. The process includes CAD modeling - layered manufacturing - post-processing. MODERMmeadw early in 2010 printed the world's first piece of beef and pork, in 2017 will be a large number of leather production.
3D printing leather production needs to go through 5 processes:
1. Extract cells from animal tissues.
2. Multiply the cells in a Petri dish and then remove the intermediate product of the cell with a centrifuge. A mix of cells that fuse cells into clusters.
3, print cell clusters by 3D printing technology.
4. Print out the product and put it in the incubator to stimulate the production of collagen.
After 5 and a few weeks, the nutrients in the cell culture fluid are depleted and the skin becomes dermal.
The production of 1 square feet of leather requires only one and a half months, without raising livestock, do not need air, water and feed. Print out the raw leather no hair no hard skin, compared with the traditional process it requires only the tanning process is simple, which makes the chemical raw materials is greatly reduced.
In 2014, Li Jiacheng spent $10 million on the research team to develop print beef and leather technology. Believe that in the near future, meat and leather products you eat will come from 3D printing technology.
