A new type3D printingThe aircraft will be launched this month with a SpaceX cargo spacecraft to the International Space Station, with the goal of printing human tissue in space. The official name of the printer is 3D BioFabrication Facility (BFF, 3D BioFabrication Facility), which aims to use adult cells and adult tissue-derived proteins (or amino acid chains) as raw materials for living tissues.Aerospace equipment operator Techshot said in a statement that this is the ultimate use3D printingThe first small step in machine manufacturing of human organs such as the heart or lungs.
Techshot is working with3D bioprintingThe machine and electronic printer manufacturer nScrypt collaborated on the project. Techshot said: “The initial phase of BFF may last about two years and will include the creation of a heart-like test print organization with increasing thickness.”

Techshot added that the next planning phase of BFF will last until around 2024. This will include making heart patches in space and then using small animals on Earth to evaluate their performance, such as rats.
Techshot said: “Ultimately, the long-term success of BFF may alleviate the current shortage of donated organs and eliminate the prerequisite requirement that someone must die before another person can obtain a new heart, other organ or tissue.”
Although it is very expensive to make human tissues in space, there are advantages to doing this work in microgravity. Techshot said that under the influence of the earth’s gravity, the human tissue on the earth will easily collapse under the action of its own weight, “the result is like a pile of gum soil.”
However, the company stated that under microgravity conditions,3D printingThe human body structure will remain stable and strong. These space-printed tissues can then be placed in a cell culture system to slowly become stronger and bear the gravity of the earth.
Ken Church, CEO of nScrypt, personally hopes to see BFF succeed, because his daughter had only one lung when he was born 24 years ago. Church said in a Techshot statement that although his daughter is still healthy and active today, he clearly remembers that he hoped that the doctor would give her a second lung.
Church said: “It will take years to assemble human lungs or other organs, but this is no longer a plot in science fiction. BFF is a road map to achieve goals, and this BFF team knows how to follow this road map. . Undoubtedly, I believe that one day BFF will provide a second lung for people like my daughter.”
