According to the NASA and SpaceX teams, “Ensuring that our systems meet rigorous safety standards and detecting anomalies like this prior to flight are the main reasons why we test. The SpaceX spokesperson said. “Our teams are investigating and working closely with our NASA partners.
A dispatcher at the Brevard County Emergency Operations Center said local officials were aware of the SpaceX accident at Cape Canaveral but were not aware of any risk to the public.
The SuperDraco thrusters are designed to push the Crew Dragon spacecraft away from a failing rocket during launch. Each engine has a 3D-printed chamber and can produce up to 16,000 pounds of thrust, with the ability to restart multiple times”.

According to UC Berkeley professor of mechanical engineering and leader of the team Boris Rubinsky,” the 3D printing of biomaterials like organs and food a lot more viable. The problem with 3D bioprinting is that it is a very slow process, so you can’t print anything big because the biological materials will deteriorate by the time you finish. They designed the device. One of our innovations is that we freeze the material as it is being printed so that the biological material is preserved, and we can control the freezing rate”.
