Traditionally, 3D design has not had to worry about real-world constraints like gravity. However, this must be taken into account when designing 3D models for printing, as the FDM printer cannot override the laws of physics and fluidize printings in the air. The printer has 3 axes, as in the real world, XY and Z, of which the Z axis is the layer thickness. The printer tries to produce a copy of the 3D model, either top-down or bottom-up, depending on the type of printer. The use of the 3d printing plastic powder comes perfect here.
In the X and Y directions, the shapes of the piece are practically limited by the properties of the nozzle, that is, how effective the cooling of the extruded plastic is and how thick the strip is squeezed out by the nozzle. Most FDM or FFF printers have a nozzle aperture of 0.4mm, which …Read More
