POLYJET technology drives the precision inside the Eden333 from Stratasys. Instead of the single head in other FDM machines, eight jetting heads simultaneously deposit identical amounts of photopolymer on the build tray with each pass along an X-axis. UV bulbs alongside the jets immediately cure and harden each layer – eliminating the need for any post-modeling curing.

The result is a perfectly smooth surface of super thin layers down to just 16 microns (0.0006″) – fully cured, that users can handle immediately after the process is complete.  Unlike the messy, multi-step baths and post processing typically associated with expensive laser and SLA machines, PolyJet technology fully cures each layer of super fine UV photopolymer model and support materials as they are precisely deposited.

There are no special baths or time-consuming post processing needed.  Support material separates easily from the fully-cured model by water jet or hand and brush – there is no extra finishing treatment required.  Model material readily absorbs paint and can be machined, drilled, chrome-plated or used as a mold.
