3D Printing is Now and Makes Real 3D Objects...
Check out this January 13, 2011 article from the
New York Times
That is a real 3D object that is made of dried plastic:
that first gets pumped as a liquid from an array of nozzles
controlled by a computer that is programmed to follow "exactly" (= mathematically = geometrically)
an inputted 3D software program describing "exactly" that very complicated shape, you're looking at right now...
Yes it is "pricey" but hang on to your wallets; it will get cheaper as the mass market grows
and retail shops pop up in your neighborhood and
If you want to know what's going on.. go to "
" the free open source 3D rendering/drawing software...
But if you think 'regular' Plane Geometry gets complicated... whoa.
Now you have to think in 3 dimensions; the regular graph paper grid is now physically an open box: a 3-dimensional space:
with height, width, and depth: you have 3 axes now: x,y, & z
and a ton of coordinates = points in space ( like a
= Global Positioning [Satellite] System
that gives you driving directions on the highway)
A 3D Object gets 'translated' into a Spatial Net, like a spider's web, or an intricate wire framework.
Imagine putting your hand into an empty cardboard box, or some object into the cardboard box,
like a sea shell (similar to the object in the photograph), or a video game 'character model' or a loaf of bread...
How do you 'define exactly' the complete location or 'surface boundaries' and space that your hand or object exists in...
inside the cardboard box? To be able to reproduce it as a 3 Dimensional Object, like an exact sculpture of your hand ...
Mathematics and Geometry can do that, that is how things get 'man-u-factured' by machines...
and how video games get made and played...
This involves very sophisticated Geometry and Computer Skills way beyond my knowledge.
But there are classmates in your school, who already know how to do this stuff everyday...
So ask around the cafeteria or online 'Geek Squads' and 'User Forums' because there's always a Day 1...
3D, 4D, 5D... Geometry is Power...
Wired Magazine article: April 2011: "How to Make Stuff"... pages 90-107.
The New Maker Toolbox: 21st Century Tools
present these revolutionary new manufacturing tools.
And the 21 Do-It-Yourself Projects List for Young Inventors, at the end of the article,
all have their own internet links with Instructions)
"Unlike mills and lathes, which make parts by
material from a solid block of stock,
3-D printers make physical objects by
adding material a little at a time.
Several kinds of 3-D printing technologies are available.
Reading the following List will require some Science Dictionary research...
Selective Laser Sintering
-- uses high-temperature lasers to melt powdered metal or plastic into durable 3-D parts.
-- uses a laser to solidify photo-sensitive liquid polymer, layer by layer.
Laminated Object Manufacturing
-- uses glue to bond layers of material that have been cut by a blade or a laser cutter.
"Maker-Bot's" entry level 3-D Printer: The Thing-O-Matic ($1,300)
-- uses fused deposition modeling to melt a filament
made of the same plastic used by Lego bricks, fed from a spool to its heated nozzle.
These are examples of New Tools in the 21st Century New Machine Shops:
