3-D or Not 3-D Part 3: 3D Printing

You’ve probably heard some considerable buzz by now regarding a technological process dubbed ‘3D printing.’ To boil it down,
the concept essentially begins with a 3-dimensional model and applies it to a process which replicates that model layer by layer by scanning thin materials to produce a physical representation.

What distinguishes 3D printing from traditional manufacturing methods is its ‘additive’ process which builds its components throughout its manufacturing as opposed to introducing previously manufactured elements to the product. This radical departure from previously dominant manufacturing techniques seeks to expedite and eliminate costs and reduce tools, thereby revolutionizing countless industries.



The elaborate process involves file preparation and conversion, necessary prior to printing stages. The complexity of these steps also depend upon the products and the type of printing being made. Various processes include stereolithography, DLP (Digital Light Processing), Extrusion, Inkjet, SDL (Selective Deposition Lamination) and EBM (Electron Beam Melting).



Material types that are utilized in 3D printers include ceramics, plastics, metals, paper, food and even living tissue. Another benefit that the process claims is its energy efficiency.



The various markets in which 3D printing is expected to reimagine are vast and diverse. Prototypes are currently being developed for multiple businesses and consumer needs with no signs of letting up. Which field or industry will reap the most rewards from 3D printing remains to be seen. Of course it won’t be seen the way we saw it before, but that’s the whole point, isn’t it?

3-D or Not 3-D Part 2: The Movies

These days It seems commonplace to scan the local movieplex listings and expect at least one or two features to be presented in 3-D or IMAX. In the early Fifties, however, such a presentation was something of an ‘event’ and, to some degree, still is. Nevertheless, the cynic in me can’t help but feel that it’s all just an elaborate excuse to hike up ticket prices and charge $9 for the obligatory tub of popcorn.

Competition with television entertainment is the primary factor in 3-D’s resurgence just as it was in the mid-Twentieth Century. The theater experience needed to be drastically different and offer an element that couldn’t be replicated on a small screen.

Often 3-D movies from the Fifties featured gratuitous moments where objects or actors lunged and leaped towards the camera, however impractical and awkward those displays might have looked in 2-D. These scenes, clearly staged for the sole purpose of accenting 3-D’s assets, nevertheless complimented their reputations and came to be expected by moviegoers. Modern features like Avatar and Gravity go out of their way to avoid using the process excessively or distract from their stories. As a result, they don’t seem to conjure up particularly memorable three-dimensional scenes— yet everyone remembers the paddle ball guy in House of Wax.

The first film to lucratively mix low-budget fare with color 3-D was Bwana Devil, an indie adventure flick about big game hunters going after killer lions in Africa. It proved popular with audiences and grossed $5 million. Columbia Pictures and Warner Brothers both took notice, producing the 3-D studio features, Man in the Dark and House of Wax starring Vincent Price.


Westerns soon hitched their wagons to the 3-D train with Fort Ti starring George Montgomery, Hondo starring John Wayne and Taza, Son of Cochise. The horror/sci-fi genre, well-suited to the sensational gimmick boasted It Came From Outer Space, Robot Monster, Creature From the Black Lagoon and its sequel, Revenge of the Creature. Other 3-D films included The Diamond, the MGM musical Kiss Me Kate and Alfred Hitchcock’s Dial M for Murder.

After the Spanish-American Eurowestern, Comin’ at Ya!, 3-D experienced a resurgence in the early 1980s when the process invariably became a profitable means to jump start tired franchises like Friday the 13th and Jaws.

Since then it has seen intermittent reception but 3-D’s implementation is generally a resort the industry occasionally falls back on when returns are low. The more the movies turn their profit and audiences’ tastes favor genres suited to the technology, the more we can expect to see things ‘comin’ at ya.’ Sometimes it’s that extra dimension that makes the difference.

Next week we’ll explore the intriguing and curious industry known as 3D Printing. What is it? How does it work? Will it affect our future? Stay tuned.

3-D or Not 3-D Part 1: The Science Behind 3-D

A form, image, style or representation visible in ‘three dimensions’(possessing length, width and height) is known in common vernacular as ‘3D’ or ‘3-D.’


A popular device developed by Charles Wheatstone in 1832 was the stereoscope which provided separate versions of a singular image which were viewed by each eye and adjusted by one’s brain to create the proper image. Polaroid filters were similarly married to this process by scientist Edwin H. Land in 1929.

Inventors had been experimenting with stereoscopic photography since the late 19th Century but its application in the filming and exhibition of motion pictures would not proliferate until the early 1950s. Projection of film with polarized filters necessitated two separate prints and likewise required special screens, not to mention large and expensive camera equipment and apparatuses.

Specially polarized 3-D glasses were also needed for the viewer to see the stereoscopic effect with color-coded images being read by each eye looking through a similarly colored filter lens. Polarized lenses, which assign images in two separate polarized projections to each lens are now popular in theaters that feature 3-D movies, especially Disney World.

Now that we’re familiarized with some of its basic principles, we’ll look back at some of the classic films of 3-D’s golden era in next week’s post. Be there (in the dimension of your choice)!
