Recoater blade reservoir and adjustment mechanism for stereolithography rapid-prototyping systems that allows removal and replacement of the blade-reservoir without adjustment to the blade height or rake settings

摘要

The invention consists of a replacement recoater blade system for stereolithography rapid prototyping systems. The replacement allows the blade-reservoir to be easily and quickly removed from the system for cleaning or replacement without change to the important gap or rake settings that determine how the blade functions with relation to the surface of the resin. Thus, the operator of a stereolithography system can remove and replace a blade-reservoir without going through the lengthy process of having a trained technician reset the system before it can build models again. Also, the replacement recoater blade system has a resin-level viewing window on both sides of the blade-reservoir. This allows faster setup and/or checking of the resin level within the blade and allows the operator to more easily monitor the level whilst the stereolithography system is building.
