3D printing, also known as additive manufacturing, is a process where a three-dimensional object is created by laying down successive layers of material under computer control. The object is built from a digital file, with the printer making multiple passes and releasing a small amount of material in each layer. Common file formats for 3D printing include STL and VRML. 3D printing technologies range in price from $300 for basic desktop printers to much higher amounts for more advanced systems.

3. 3D printing or additive manufacturing is a process of making three-dimensional solid
objects from a digital file.
The creation of a 3D printed object is achieved using additive processes.
In an additive process, an entire object is created by
applying successive layers of material.
Each of these layers can be seen as a thinly sliced horizontal
cross-section of the eventual object.

4. How 3D Printing Works
A three-dimensional object is
modeled by a designer using
software such as CAD
A design is sent to the printer, and a
Printer material is selected.
Once all the layers have been added,
the object is fully formed.
The printer makes passes, releasing
a small amount of the material in a
layer-by-layer process.

What File Formats Are Used In 3D Printing?
The most common and universal file formats for 3D printing are STL
and VRML. STL stands for “stereolithography”: a 3D rendering that
contains only a single color. This is typically the file format you would
use with desktop 3D printers. VRML (“vermal”, .WRL file extension)
stands for “Virtual Reality Modeling Language: a newer digital 3D file
type that also includes color, so it can be used on desktop 3D printers
with more than one extruder (i.e. two more nozzles that each can print
with a different color plastic), or with full-color binder jetting technology.

Ideas on 3D Printing and Technology Based Systems In
Our Schools and Classrooms
“It is not about the technology; it’s about sharing knowledge and
information, communicating efficiently, building learning communities,
and creating a culture of professionalism in schools. These are the key
responsibilities of all educational leaders.” Marion Ginapolis
“We need technology in every classroom and in every student and
teacher’s hand, because it is the pen and paper of our time, and it is
the lens through which we experience much of our world.” David Warlick“
“Learners in the internet age don’t need more information. They need
to know how to efficiently use the massive amount of information
available at their fingertips – to determine what’s credible, what’s
relevant, and when its useful to reference.” Anna Sabramowicz

15. Technology For Thought…

“The most important thing that
schools can do is not to use
technology in the curriculum
more, but to use it more
effectively.”
- John G. Palfrey and Urs Gasser

16. We must not think one mode of working, thinking, or building
is better then another. But think of how we can merge best practices
and experiences to make a holistic learning experience.
