RAPID PROTOTYPING PROCESS
The rapid prototyping process utilizes virtual designs drawn
from CAD or modeling software. It then creates very thin cross sections.
Each of these sections is physically created, and added to the previous
cross-sections until a model is complete. The finished physical model and
the virtual model correspond almost exactly. The rapid prototyping machine
reads data from a CAD drawing, usually using the STL file format, to exchange
data from the CAD software to the machine. It utilizes a process
called additive fabrication to put down these successive layers, using
powders, liquids or sheet materials. The model is then heated, fused, or
otherwise treated to connect each of the cross sections until the full
model is created. These physical layers correspond to the virtual cross-sections
created in the CAD model. This process allows manufacturers to create
almost any shape.
Stereolithography (SLA®) provides accurate
models and patterns in record time. Concept models, masters and patterns
are created in record time using stereo lithography, the most accurate
and precise rapid prototyping technology available. Complete in-house finishing
capability for production-like prototypes ensures your model and
patterns are delivered on time, ready for immediate application.
SLA models and patterns can be produced in a matter of hours from
any popular CAD system. Starting with CAD geometry, IGES or STL data,
Precision Pattern' engineers will guide your most demanding project through
every step of the process to guarantee timely delivery. In-house developed
software and special finishing techniques make it possible for Precision
Pattern to provide the highest level of quality at competitive prices.
Because of their accuracy and ability to reproduce fine details,
SLA models are ideal for use as concept models, form and fit studies,
and as master patterns for a variety of molding techniques. Options
for finishing include color-matched painting, texturing and pad printing,
to give your model a "production quality" look and feel.
SLA Standard – Built in 0.007" layer thicknesses,
our SLA Standard process is suitable for prototypes and master patterns
that need to be built quickly and economically.
