Stereolithography
is a method of rapid prototyping that transforms 3D CAD data
into precise physical models known as stereolithography (SL)
prototypes.
A UV laser is used to solidify a photosensitive
epoxy resin within the SLA machine.
The
UV laser builds (cures) one .004" - .006" thick
layer at a time on top of a platen, so that each subsequent
layer is bonded to the previous.
Upon completion, the part is removed from the machine to
be cleaned and post processed.
How
Can SLA Work for Me?
Many companies have used SLA to test
market an item without incurring large upfront tooling
expenses.
Engineers use SLA for form and fit
studies, testing, and "peace of mind" before
investing in costly tooling.
How
long does the process take?
After a
3-D file is made and fed into the SLA machine the process is
completed in just hours as compared to the days or weeks needed
for most other prototyping methods.
What
factors determine cost?
While
the cost is a fraction of a "tooled" prototype,
cost is determined by:
Products Dimensions - larger prototypes will require more
material and machine time.
Finishing - Processes such as painting will add costs.
Development / Design - the process begins with an STL
or 3-D CAD drawing. If you submit an STL file to us that's
"ready to go", your only cost will be for SLA
machine time and finishing. If Sierra Pacific is involved
with creating or modifying a 3-D CAD file, then additional
costs will be incurred.
