Stereolithography, often called SLA, is one of the best known processes for taking a computer model directly to a plastic part.  Invented in 1986, this technology uses a laser to draw on the top layer of a vat of photopolymer.  Everywhere the laser hits, the liquid turns to a solid.  At PADT about 40% of our prototyping jobs are carried out on one of our SLA machines.

Accuracy and Surface Finish

The first key advantage of using SLA is the accuracy of the parts created.  It is excellent for parts with small details or for parts that cannot allow much shrinkage or warping.   The machines that PADT uses can deliver accuracy up to 0.003".  The next big advantage of Stereolithography is that finished parts can be processed to produce a  high-quality surface finish.

Your Stereolithography Experts

PADT has been operating at least one SLA machine non-stop since 1994.  We have produced tens of thousands of Stereolithography prototypes for customers in almost every industry.  We currently operate a Viper Si2 and a ProJet HD6000, both from 3D Systems . We also utilize a UnionTech RSPro 450 device for larger parts.  PADT's manufacturing engineers are experts at using these systems, choosing the right materials, and setting up the runs.

Building the part is just the start.  After it is made, it must be removed from the system, support must be removed, and the proper surface finish must be applied.  This is where PADT really shines because our technicians have years of experience with such tasks, and are also accomplished artists and craftsman outside of their jobs at PADT.  The parts that PADT delivers to our customers are a step above what competitors can provide.
