3DFacture's resin vat for the Draken has a special Teflon coating which dramatically extends the lifetime of the resin vat by *up to 10 times compared to regular PDMS-coated vats, eliminating frequent replacement and reducing maintainence costs.
 
Furthermore, this coating is impervious to most solvents, is compatible with many more resin types (even those that do not depend on oxygen inhibition unlike PDMS), and greatly reduces suction forces for better quality prints and reliability. 
 
Ships within two weeks.
*estimated life of >100,000 layers before Teflon layer needs replacement due to warping from constant pulling
