EnvisionTEC

If you're looking for a decent and affordable SLA machine, these machines seem to work pretty well, but EnvisionTEC's customer service has been a consistent disappointment - we have received several incorrect orders and had one or two dropped entirely.

Strengths: A range of SLA machines from affordable desktop to larger machines. My experience with their Perfactory Micro-Edu machine has been largely positive. Machine resolution is good and it is easy to use.

Needs to improve: Perfactory Micro EDU machine is clearly intended more for the hobbyist, and not for an engineering lab where it is kept busy a high percentage of the time. The "basement" component has some durability issues that require more frequent replacement than we expected. If this part isn't kept in top condition, SLA components can contain defects, or fail to build entirely. Basement life can be increased by frequent filtering of the SLA resin, which is messy, to say the least. Another disappointment was that the machine we received was largely a beta release, and did not work with all of the "compatible" materials (which they were happy to sell us), requiring about 6 more months of development by EnvisionTEC.
