RE: Stereolithography Limitations

There's only a couple of limitations to stereolithography... speed and strength, oh, and cost, heat resistance, did I mention cost, flexibility, reliability, size, accuracy, brittleness, solvent resistance, and don't forget cost. This mail list frequently explores the future of RP (excursions which I thoroughly enjoy by the way). Stereolithography is just one of the stepping stones to that future and on the way its unlikely any one method will overcome all these "limitations". On the other hand, rapid fabbing has made great in-roads into the tooling and prototype markets where it's unique capability to turn a computer dataset directly into a 3D part is often justified for small quantity situations.

As for my company, material strength and intolerance to heat are probably the most limiting . We have been known to wrap parts in fiberglass and backfill quickcast patterns with epoxy/metal resins to improve these properties.
