White, Strong & Flexible 3D printing movie

Fascinating movie!! It is great to see how this works!

I have a dumb question that has been bugging me ... how does the laser fuse the material, when the material itself is opaque? Doesn't it have to pass through the material to get to the layer it is fusing at that time? Is it really the intersection of two or more laser beams where the fusing occurs?

Inquiring minds want to know! :-)

George, as far as I understand, the laser is melting the top layer, then there is another layer beeing added by the printer. Layer by layer, the plastic melts together.

I hope that Marcus is right because otherwise I've misinformed a lot of people.

Great clip guys, now all you need is a robot or fairy to sort and clean the parts for you and you'll be set. Really tho, it's cool to see how hands on you guys are

Thanks for the explanation. Ballpark figure, how much does one of these SLS printers cost? ;-)

Its like a car, it depends on the options. But, a good one can be had for between 150,000 - 300,000 or so. Metallic rims not included.
