Just What is 3D Printing?
Stereo-lithography Apparatus – SLA
&
FFF – Fused Filament Fabrication
3D printing is a term used to describe the two basic types of “additive” manufacturing. This game changing technology offers a dramatic departure from the normal subtractive (milling) and formative (casting) manners of making things. The SLA and FFF process of manufacturing is capable of re-creating complex three-dimensional shapes that simply can’t be milled or caste. For the answer to the question: Just What Is 3D Printing? – see the two links below for understanding the fascinating processes that open up unlimited potentials:

Reasons For Success
- 3D printers have become reliable and affordable in commercial and private settings.
- The ability to create a product on a computer and then easily turn it into a physical object empowers the design and prototyping process.
- 3D printing does not create the waste of trimmings and scrap that many traditional manufacturing methods produce.
- 3D printing makes it economically feasible to produce one-of-a-kind items.
- The capabilities of 3D printers in terms of materials cost and speed is still not competitive with traditional manufacturing, but is advancing rapidly.
- 3D printer manufacturers are already profitable and their revenues are growing rapidly.
- 3D printing allows for the use of the smallest amount of material to be used to build the strongest structure possible.
- 3D printers don’t depend upon economies of scale for justification of goods made.
- Software can endlessly tweak and improve just about anything. The cost of setting up the machine is the same whether it prints one object or many.
- 3D printing conjures up the idea of my “personal factory!”
- Improvements in techniques, additive media, and design will lower costs that will compete with and surpass many types of present manufacturing processes.
