What is a Prototype?
A prototype is the
term for a "first part" (or maybe several parts) produced during the process of
designing and developing a product.
What is Rapid Prototyping?
RP is a method of quickly
producing a free-form, 3-Dimensional model from a mathematical description, usually a CAD
model.
Why is "Rapid"
Important?
The faster you can progress from your initial concept for a product to
placing that product on the market is one of the most critical factors in gaining market
share. Decreasing product development time is one of the major goals of engineering
departments.
KVCC can help you with your Rapid
Prototyping efforts.
We can supply you with a variety of training, from multi-media
coursework to hands-on model building on a StrataSys Model 1600 Fused Deposition Modeling
Machine.
What is
Fused Deposition Modeling?
FDM is one form of rapid prototyping. In this process, the
model is formed by extruding a thin (0.012 inch wide) bead of melted plastic. You can
picture it as building a model with a tube of toothpaste, layer by layer. First the
outline is "drawn", then the interior is filled up like you were coloring it in
with a crayon. By building up many 0.010 inch thick layers, one on top of the other, the
3-D model is formed from bottom to top.
Possible Uses for FDM Rapid Prototype Models:
- Concept Models
- Form, Fit & Function Models
- Marketing Examples
- Master Patterns (requires bench finishing of RP model)
- Direct Wax Investment Casting Patterns (requires bench finishing of RP model)
What Modeling Materials Can Be Used?
- ABS plastic - can be painted
- Investment Casting Wax
- Polyamide
Size of Models
The "Working Envelope" of this machine
is 10.0 (X) x 10.0 (Y) x 9.4 (Z) inches. Models larger than this can be made in sections
and glued together.
Tolerances Held
Machine specifications state that this
process is capable of holding tolerances of +/- 0.006 inch. The actual results depend on
the forming conditions, process parameters and part geometry. You should
"benchmark" a typical part for your application.
