For 3D printers, I've seen "TRANSLUCENT" material advertised for sale, some material even called "TRANSPARENT".  I'm skeptical though, that a truly transparent object can actually be printed.  Is this just a miss-translation of the two terms?

 

I can believe that a somewhat 'cloudy' or blurry item could be printed off, but nothing clear like glass or acrylic that we've all come to refer to as transparent.

 

Since we have a few people here with 3D printers, I figured this was the place to ask and to be set straight or educated.   - Thanks

To my knowledge, a clear glass kind of output is not possible as yet. The printing process introduces occlusions (think imperfections in diamonds and crystals) or small surface irregularities that refract light resulting in a diffused or translucent effect. Best approach might be to 3d print a mold and brush or fill with a liquid polymer.

Thanks guys!  I appreciate your answers.  I thought as much, but had to ask to be certain because I don't like making assumptions with little to no facts and then finding out I've been wrong afterwards.

Yeah, it's totally possible, and has been since 1990.

I wish you didn't have to buy a new tray when you switch materials.

Wow... there is a ton of work involved, for a simple shape like a lens, that's cool, but on more complicated shapes it appears problematic at best.  But thanks for posting that article, it was VERY informative and good enough to print off for future reference.  :thumbsup:  :thumbsup:

I purchased some semi-transparent ABS material sometime back to create LED covers for a Power Droid (Star Wars) costume for my 11yr old son (at the time).  They turned out acceptable for what I needed it for, but they aren't totally clear like one might expect. 

 

Here's a video (that jumps directly to the spot where I demonstrate what it looks like), if you want to see it: https://youtu.be/5vy401k2Atc?t=114

 

Perhaps if I had used a solid infill and thinner layer, used acetone smoothing, etc. it could have looked more transparent.  But, it was ok for me and my son liked it.
