- Dec 24, 2013If they don't use tilt or slide, they must have found a super hydrophobic surface coating that is optically clear. OR - they're floating the resin on top of another liquid. (It's like they're kind of "hinting" to that in the video when they drop the colored resin into the liquid)
I can't think of any other way they are keeping the "stick" to a minimum.
They never mention the resolution of the projector. You can also see that the printed objects do not have a very good XY resolution. They mention that the part resolution is about the same resolution as a monitor, which would only be about 100dpi - not that great!
Also, I can't figure out where they put the projector?! Are they mounting it on the back, facing downward, bouncing the image off a couple mirrors? How can they get a projection 8.5 x x11" from inside the box? Baffling to say the least.
I think they just lift it up from the liquid surface.. At least it looks like that in the video..
Yes it is possible.
Personally thought the lack of technical detail puts me off, I'd like to know how they are doing the release from the vat bottom.

Is it possible to do this, Solidify resin with visible light within 10 secs?
any over claim from manufacture?
A start-up in Florida has developed a 3D desktop printer which it claims has one of the highest 3D printing-speeds available.
The company tangible engineering USA has developed the 3D printer called Solidator to use stereolithography and projector DLP-technology to turn liquid plastic (similar to nail polish) into a solid 3D object with just visible light.

The 3D object is created layer by layer upside down. Solidator is capable of creating a single layer of an object at a 100 micron resolution in just 10 seconds independent of object shape or number of objects placed on the build platform.
“This way Solidator can create six Eiffel Towers at 20 cm height (7.9-inch) in only 5.5 hours,” said the company.
“The patent-pending design using DLP stereolithography technology provides high resolution on a large print bed and allows you to create 3D objects in a fraction of the time – right on your desk.”, said Tim Fischer, president & CEO of tangible engineering USA.
The company is launching the product today on Kickstarter.com.
The printer features a 280x210x200 mm build volume. The resolution achievable allows it to create 3D Voxels with a size of 0.27 mm by 0.27 mm with a 0.1 mm layer height.
