[blindkid] Tactile Graphics

[Robert Jaquiss]

Hello:

     The use of a laser on a liquid for forming a part is known as
Stereolithography. This is one of the oldest techniques for forming a model.
More modern techniques involve the deposition of plastic droplets from a
printhead type device. Another technique uses a laser to fuse layers of
powder. There are other techniques.

Regards,

Robert

The 3D pens are neat, but the 3D "printers" I've seen are truly amazing. I
saw one on a TV show about technology. What they explained was a laser was
focused into some sort of liquid, such that areas lasered turned solid. The
intended market was to make "1-off" prototypes of products, before
undertaking the expense to make a set of molds for things like injection
molding of products. 

Implications for the blind were incredible, but the units looked really
expensive. If the cost comes down enough, the prospect of being able to
"laser print" a 3D piece at will is truly incredible!

and might be useful in providing good tactile graphics for blind students,
is 3D printing.  While this specific use has not been mentioned in any of
the newsletters I am following, it seems to me that it is worth exploring.
The field is expanding rapidly and there are relatively inexpensive 3D
printers coming on the market that might be able to quickly produce a good
tactile graphic for not too much cost and effort.  Perhaps someone
knowledgeable in technology could explore this with the 3D printer folks.
