Researchers in the Netherlands learned a rough lesson when they first tried 3D-printing solid fuels like the conventionally cured kind that today power everything from rocket-propelled grenades to space launch vehicles. Keith Button spoke to researchers who think they have a better way to make solid fuel. Plus, it’s complicated to design the fuel so that the propulsive force varies in a predictable way as it burns. Solid-fuel rockets contain cylinders of fuel that, depending on the manufacturing method, can take weeks to cure. As before, there exists a shorthand rotate3d.3D-printed rocket fuel By Keith Button | April 2019 To facilitate rotation about one or more axes, use rotateX, rotateY, and rotateZ. Here is a codepen demonstration of translation along each axis. Use translateX, translateY, and translateZ, or use the shorthand translate3d to move an object around in three dimensions. There are a total of three transformations the first is translation, or movement, along one or more axes. The transformations we discuss below all operate on these three axes.
