A SpaceX Dragon resupply mission carrying 6,500 kilos of science experiments, together with a handheld bioprinter prototype, is on its solution to the Worldwide House Station (ISS) after launching on December 21, 2021, from NASA’s Kennedy House Heart in Florida. Envisioned by the German Aerospace Heart (DLR), this moveable gadget, referred to as Bioprint FirstAid, has the potential to facilitate the fast use of previously ready bioinks containing a affected person’s cells to kind a band-aid patch in case of damage. This revolutionary microgravity printer holds promise for future long-duration missions to low Earth orbit (LEO), the Moon, and Mars and may very well be the subsequent large factor on Earth.
As house businesses put together for longer period flights, surviving in microgravity is essential, particularly for crews dwelling in shut quarters, the place a mix of stress and diminished immunity affect the unfold of disease-causing microbes. This, together with lowered immunity and elevated stress, can result in people in house changing into in poor health. Furthermore, the microgravity atmosphere itself can have dangerous results on the physique, together with delayed wound therapeutic. Because of this, house businesses have lengthy inspired analysis to know find out how to shield astronauts in house to enhance human well being.
Developed, assembled, and certified by German house firm OHB System with assist from scientists on the Technical College of Dresden, the bioprinter prototype is described as a sturdy, purely mechanical (no battery required) handheld bioprinter consisting of a dosing gadget within the deal with, a print head, assist wheels, and two bioink cartridges. The know-how demonstration in house is not going to use actual human cells however fluorescent microparticles.

When mixed with two fast-curing gels, these microparticles create a plaster-like wound masking, which will likely be printed onto an astronaut’s foil-covered arm or leg and despatched again to Earth for additional testing. German ESA (European House Company) astronaut Matthias Maure––the primary German astronaut to fly to the ISS on board a Dragon spacecraft––will dedicate a lot of his time to scientific analysis, together with testing the bioprinter.
Whereas coaching for his ISS mission, Maure experimented with the bioprinter gadget, making use of the fabric to his leg, which was wrapped in foil. The distribution sample of the printed samples on Earth, in comparison with the printed samples in house, is a vital worth for the analysis. Total, this challenge goals to check the printing know-how and assess its applicability beneath house circumstances for future missions in excessive habitats on and off-Earth.
Bioprint FirstAid gives a analysis alternative to optimize bioprinting supplies and processes. NASA considers that microgravity-based 3D tissue fashions are vital for additional understanding the bioengineering and bio-fabrication necessities important to attain extremely viable and useful tissues. Below microgravity circumstances, the stress of various layers containing cells is absent and the potential sedimentation impact of dwelling cell simulants. As well as, the soundness of the 3D printed tissue patch and the doubtless gravity-dependent electrolyte-to-membrane interface crosslinking course of may be analyzed for future purposes.
The researchers counsel that the bioprinting means of this prototype requires 10 minutes to acquire an acceptable crosslinking of the biopolymer and crosslinker (which serves as a stabilizing matrix) supplies earlier than masking the affected space like plaster and accelerating wound therapeutic by facilitating the formation of recent pores and skin tissue. If the analysis evolves favorably, the hand held bioprinter’s fast wound remedy know-how could be supreme for therapeutic bone fractures, pores and skin and muscle accidents rapidly and successfully throughout longer house exploration missions.
Furthermore, the mixture of cells, tissue-specific biomaterials, and high-resolution 3D bioprinting can allow scientists to develop new tissue and organ modeling methods to know higher the biophysical mechanisms of tissue era, regeneration, and longevity.

SpaceX Falcon 9’s launch of its Business Resupply Providers (CRS-24) mission to the ISS carrying the bioprinter is scheduled to autonomously dock on the house station round 4:30 AM on December 22 and stay there for a couple of month. Apart from the Bioprint FirstAid, Dragon delivers different science experiments to the house station, together with an investigation to watch and profile the event of crops’ shoots and roots in microgravity, a completely degradable detergent for in-space laundry by Proctor & Gamble, and scholar microgravity science tasks.
The hand-held gadget will develop into the third bioprinting system on the ISS, becoming a member of Russia’s Organ.Aut 3D bioprinting platform, which efficiently reached orbit in December 2018, and the BioFabrication Facility, developed by nScrypt and Techshot (just lately acquired by house large Redwire).
What’s extra, these experiments will be part of the lots of of investigations at present being performed aboard the orbiting laboratory within the areas of biology and biotechnology, bodily sciences, and Earth and house science. Advances in these areas will assist hold astronauts wholesome throughout long-duration house journey and show applied sciences for future human and robotic exploration past LEO to the Moon and Mars by means of NASA’s Artemis program, with the primary crewed mission slated to happen no sooner than 2025.
