JP System 5

Overview
    JP System 5 is a computer aided rapid prototyping technology which uses layers of adhesive paper to form a physical model. The models are assembled manually.
    It was developed in 1995 by Schroff Development Corporation, Mission, Kansas.
    It uses stereo lithography (.stl) files commonly found in any 3-D solid modeling CAD package to create prototypes.
    The system comes with a plotter with a cutting blade, JP design slicer software, and a registration board (~$7500).  The system requires a personal computer to operate it.
    Mainly marketed to universities who desire rapid prototyping curriculum, and small design firms
 
Manufacturing Process
 A detailed view of the manufacturing process can be found here

Characteristics of Prototype
    Not reccomended for heights over 7"
    Maximum length and width 21" X 17" for Premier Edition, 8"x11" for Standard Edition.
    Average $2 - $10 dollars per prototype constructed.
    Standard paper - 14 cents per sheet.
    Fine high gloss paper - 16 cents per sheet.
    Medium semi gloss paper - 19 cents per sheet.
    Heavy semi gloss paper - 33 cents per sheet.
    Takes 1 hour to build up 1 vertical inch
 
Advantages
    Inexpensive relative to other rapid prototyping technologies.
    The process is quicker than other layering processes.  Manufacturing time depends on the intricacy of the prototype.
    It offers a good introduction to rapid prototyping technology.
    Does not require harmful chemicals and resins.
    It does not require recallibrations after each use.
    Materials are easily accessible.
    User friendly.
    The system does not require additional supports during the build process.

Disadvantages
    Accuracy depends upon experience and care of the user.
    The thickness of the material limits accuracy.
    Final prototype is not as aesthetically pleasing as the products of other design processes.
    Some parts may be difficult to build as a single part.
        - Parts that are tall relative to a narrow base.
        - Parts that can not be oriented to provide a flat surface upon which to assemble the sections.
        - Parts that narrow toward the center of the part.
        - The overall height of the part is taller than the registration pins used to register the layout sheets.

There is a plotter/setup for JP System 5 at Carnegie Mellon.  See Professor Finger for further details
