Scientists have captured a beautiful image in unprecedented detail of the vast Milky Way galaxy, of which our own solar system is a part.
云耀深维创始团队认为，金属3D打印要实现真正的批量生产，必须提升原生打印的精度及表面质量，只有当精度足以逼近净成形、后处理不再是漫长的“手工作坊”式劳作时，金属增材制造才能在成本与效率上与传统精密加工展开正面对决，从而进一步叩开规模化工业应用的大门。

This would be exceedingly hard to anticipate. As NASA puts it, “Calculating the probability of this penetration cascading into loss of deorbit capability has a very large range of variables, making predictions ineffective.”
