Making Diffusing Parts in rapid prototyping

 As you might have already guessed by the way we mentioned earlier on in regards to tailoring prototypes, there are directions made to work out simplified ways to make this particular aspect of a prototype more realistic and without hassle.

 

Nevertheless, the hardest part is deciding how strong or weak you want your diffused light to be and then how you are going to make your prototype's diffusing effects actually be like that, to diffuse the exact proportion.

 

This difficulty can be said to have been tackled with the Full-Width at Half-Maximum (FWHM) and Half-Angle (HA) of light diffusion which are metrics that describe and measure how a translucent material diffuses light. Metrics such as FWHM speak to the size of the area where 50% of the light is passed through by a thin cross-section of a spherical object. While metrics like HA describe how much wider this transmission window is, with higher numbers indicating more area covered.

 

Using these two measuring scales, the system has been made a little easier whereby customers will specify the range they want their Part's diffusion of light to be around.

 

But even with these measurements manufacturers still find difficulty in meeting the exact specification as a lot of other things are put into consideration. Like the thickness of the prototype wall, the amount of the diffusing agent, the level of tinting effect on the paint, and the structure of the resin used will affect the rate a  part diffuses light.

 

Like, a part with 50% of a diffusing agent without tinting done will diffuse light differently from the same kind of part with the same amount of diffusing agent but with a different wall thickness.

 

For two parts with different make-up materials but with the same amount of diffusing agent to have the same diffusing effect, different aspects as mentioned above must be reduced or added where necessary.
