3D Technology and Tradition
Meet for Dinner
 In
Japan, traditional artisans always incorporate an intentional
flaw in their pieces because it is believed that to do otherwise
would insult the gods, since only deities can create perfect
things. Such flaws also remind a viewer that the work is the
product of an individual's hands. How, then, does a manufacturing
company convey a handmade look from a computer-designed, machine-made
product?
The Pfaltzgraff Company in York, Pennsylvania, a manufacturer
of ceramic dinnerware, has elected to combine modern design
technology with its 200-year-old tradition of hand-crafted
techniques. Involved is an extensive product line developed
over five generations and now encompassing more than 40 dinnerware
patterns as well as lines of flatware, beverageware, and glass
gift and servingware. Depending on what is appropriate, Pfaltzgraff's
manufacturing methods include slip casting, jiggering and
powder pressing.
The company is using CATIA Version 4, developed by Dassault
Systèmes and marketed by IBM, Dallas, TX, to mimic
the art of a craftsman. According to John Nace, manager of
CAD/CAM Technology for Pfaltzgraff, "Today we're running
a network of nine IBM RS/6000 work-stations with CATIA as
an integral part of the design process, bringing together
the work of artists, technicians and engineers." In the
first stage of implementing CATIA, designers developed new
extensions to existing lines. In doing so, it was crucial
that new pieces match the look and feel of those produced
in traditional ways. One challenge was to replicate the look
of "throwing rings," subtle markings made by artisans
when working the clay. Pieces are designed using a software
application that adds color, pattern and texture. These designs
are then imported directly into CATIA, accelerating the development
process.
Another distinctive use of CATIA at Pfaltzgraff involves
the accuracy of the master cases, from which casts and molds
for ceramics are made. The master cases are now being developed
with such precision that they need to be machined only once
and potentially can outlive the life cycle of the actual product.
As Nace comments, "Technology is serving the company's
200-year-old tradition of a hand-crafted look. The nuances
and subtleties of surfacing requirements for pottery design
demand advanced capabilities in the technology we use."
