![]() ![]() Relationship between frequency and wavelength The Wavelength is inversely proportional to frequency. The wavelength applies to both traveling waves and standing waves. It is represented by lambda (λ) and has units of distance like meters, cm, mm etc. The wavelength of a wave is the distance between two adjacent peaks or troughs of adjacent cycles. So if a wave repeats 5 times in one second its frequency would be 5 Hz. The unit of frequency is Hz which corresponds to the number of waveforms that repeat in 1 second. The frequency of a waveform is the number of times a complete waveform is repeated in a fixed time period.

There is also the Positive Quadrant setting, which moves the object into the +X, +Y, +Z space for printing software that prefers it.C or Velocity of Light = Speed of Light (299,792,458 m/s) In it, you can choose whether your STL file will be saved in ASCII or Binary, what the Up Axis is and Unit Scale for the destination environment. Once you have clicked OK you will get this options window: Polygons with fewer sides (1-point, 2-point) will be deleted. If your object has any polygons of a different number of sides you will see this message:Īny polygons in your object with more sides will be tripled. When you export in STL format, the first thing to consider is that the format only supports triangles. If you are bringing in an STL made in LightWave, the default of 1 m is good. Import Units - Since STL objects have no inherent unit system, one needs to be determined from the number field and the dropdown next to it. ![]() This merely rotates the object so it stands upright. Up Axis - For LightWave it’s Y, but bringing in an STL created with other software might have a different Up Axis.Weld - welds the points of the mesh so that using Select Connected will select the whole mesh.When loading in either fashion you will be presented with an Options box like so: ![]() ![]() STL files can be dragged and dropped onto LightWave to load or they can be loaded using the Load Object file requester. It is the lowest common denominator that misses out on some of the bells and whistles of more recent formats but can be guaranteed to be understood by all software dealing with 3D printing. STL is the grandaddy of 3D printing file formats and is in regular use today. ![]()
