arun, I'm generally dubious of posts referring to so-called "experts"; however, the information you presented is generally correct with a few caveats. 1) 3-D Sysyem's Stereolithography is already used to make functional parts in medical applications. Furthermore, because of its greater accuracy than Stratasys' FDM process, it's the market leader in rapid tooling. 2) I'm not sure what is the basis for claiming 3-D Systems is "the smoothest running company". 3) Helisys uses lasers in a process called laminated object manufacturing (LOM). It uses paper as a modeling material which results in inexpensive, wood-like models. It's advantages are large model size and cheap material costs. These models are suitable for use in sand casting, but problematic for hollow shapes because it's difficult to remove the waste paper from the cavity. My feeling is they're competing for a different client base. 4) I assume the Soligen (I'm not familiar w/them. They're not even listed as a competitor in Stratasys' 10K.) technology is similar to 3-D's recent ink jet technology. 3-D's ink jet system is faster and requires fewer environmental controls than their stereolithography based systems, but it is still more expensive than Stratasys' Genesis. My guess is the Stratasys modeling material is also superior. 5) DTM Corp. also uses lasers to sinter or harden powdered material. I think it's predominantly a two-horse race between Stratasys and 3-D. 3-D had the early lead, but Stratasys has been rapidly increasing market share at their expense. My guess is they are both excellent companies w/terrific technology. My money just happens to be on Stratasys because I think it will grow faster and farther. If I were far wealthier, I'd probably bet on both companies. --Robert
