Just to add on the previous discussion - Form 1 uses conventional scanning laser SLA technology, which uses laser and two actuated mirrors to project images onto the resin as you can see in a laser show.

Titan 1 uses a DLP projector to project images onto the resin in a two dimensional fashion. Therefore, time required to expose the resin is shorter. There are less moving parts in the printer. The DLP projector is a matured consumer product so it is much more reliable and easier to maintain than a customized scanning laser system that requires sophisticated alignment and calibrations. The DLP projector can be easily moved to adjust the native pixel size from 37-100 micron, while Form 1 has a fixed laser spot size of 300 microns which is not enough for fine jewelry printing.

Hope this helps
