[Blindmath] [Blind math] Spatial Abilities

[Sina Bahram]

I think we might need to expand a bit on this, and only because I suspect Ken was in a hurry when writing his email.

A 3DPrinting pen like the 3doodler, which I also have, is not appropriate for making models of the kinds covered in a multivariable calculus class or anything involving solids, really. While, it can, with a good bit of practice/carefulness, be used to construct something as simple as a cube or 3dimensional prism, the resulting model is not anywhere near the rigidity of a 3d printed one, and furthermore, if dimensions matter or if scale is important in any way, I'd recommend some caution.

As for a 3d printer as low as $100, I only know of one as cheap as $200 or so, and that was only for the first batch of backers on kickstarter before jumping to $300 or $400, but I don't recall a whole printer for $150 or less that is not a pen or handheld.

The point is though, that if you can swing $400 to $800, there are entire companies dedicated to serving this tier of cost point, and the major difference is software support, which is getting better all the time (open source and all that), and size of the build plate.

Take care,
Sina

Actually the 3d printers can be found as low as $100 and I use a 3d pen
right now.  I will be getting one of the new lyx 3d pens as soon as they
come off kickstarter but for now the 3doodler is pretty cool.

OK, so APH produces these 3D shapes ... but with the advent of the 3D
printer, this might make production of such shapes more readily available
to teachers ... if they had ready access to one.  Perhaps this could be a
tool that could help teachers obtain the 3D shapes they need independently
of places like APH.  Just a thought.  I just looked up the price quickly
using Google .. .they range from $600 to $3000 ... fast glance there.  So a
teacher couldn't just go out and throw down pocket change and get one.
Still, if a school district could pop for the money, plus the software
required to drive the printer ... it might make production of such objects
easier.
 
Now all we need is a breakthrough in production of a multi-line Braille
display ... but that's for another discussion group.

would like to send them to me. There are organizations in the US, primarily
the American Printing House which  considers producing things that might be
of value to the blind population
