Virtual Ornaments
A few years ago I began to investigate the concepts
of art-to-part and single part custom manufacturing.The
original designs had to created on a CAD system either manually or by algorithm
and then machine produced without any manual intervention.Rapid
prototyping and laser cutting technology were both reviewed and the later
selected for possible use.I also
had a long time interest in geometric design.At
that time one of my CAD classes took some of there window designs, created
from a complex series of overlapping circles, arcs, and splines, and had
them laser cut.The results were
astonishing.
With the holidays not to far off, and being an avid
ornament collector, I thought that laser cut ornaments would be an interesting
way to try this technology.The ones
I had first seen were created from wood with a thickness of 1/8" to 1/4".They
were very bulky compared to the fine cuts that were used to create them.I
also wanted to use wood, but wanted the material and designs to match the
precise cutting that was possible.After
some experimentation, I settled on 1/16" mahogany, with each ornament being
approximately 3" in diameter.The
result was a very delicate almost lacelike quality design.The
laser cut burns the material, so the edges of the cut are black while the
faces remain the natural finish.The
burning also gives off a unique aroma, even a year later.
The initial set of designs were based on abstractions
of Russian and Egyptian Ornamental, Polish Paper Cut, Prairie School and
Victorian Stained Glass designs.Others
included Snowflake, Chinese Ornamental, Arabian Stone and general Geometric
designs.The current series can be
viewed at the www.netcom.com/~bitart website.
The current series was accepted into the Illinois
Artisans program and as time went on a few fine art craft shops around
the country purchased them. This
last season, I intended to add to these designs, but started to think about
a three dimensional version.To investigate
this possibility I decided to craft them digitally before attempting to
construct them physically.
The three dimensional digital designs became increasely
more interesting then actually making them, that at this time they only
remaining in their digital forms.These
ornaments are composed from their laser cut counterparts by assembling
them across the major axes of a sphere.The
starting point was usually two vertical elements and one horizontal element.Since
the symmetry varies, some of the vertical placements were make across the
diagonal axis.The Prairie School
Stained Glass design was formed by crossing two designs and then placing
four other ones around the edges in a boxlike arrangement.Also
for the holidays I "painted" them traditional holiday colors; the actual
ones would remain a natural wood finish.
Depending on the original design, the intersecting
edges became increasely more complex, as did the center of each ornament.The
ability of digitally joining these designs is far more capable than what
may be physically possible.Some
of these will not be possible to actually reproduce using their original
laser cut pieces.But using self-supporting
rapid prototyping technology, all might be possible.I
will have to wait till next season to see how that might turn out.
