Methods and systems of stereolithography for building cost-efficient and
time-saving multi-material, multi-functional and multi-colored
prototypes, models and devices configured for intermediate washing and
curing/drying is disclosed including: laser(s), liquid and/or platform
level sensing system(s), controllable optical system(s), moveable
platform(s), elevator platform(s), recoating system(s) and at least one
polymer retaining receptacle. Multiple polymer retaining receptacles may
be arranged in a moveable apparatus, wherein each receptacle is adapted
to actively/passively maintain a uniform, desired level of polymer by
including a recoating device and a material fill/remove system. The
platform is movably accessible to the polymer retaining receptacle(s),
elevator mechanism(s) and washing and curing/drying area(s) which may be
housed in a shielded enclosure(s). The elevator mechanism is configured
to vertically traverse and rotate the platform, thus providing angled
building, washing and curing/drying capabilities. A horizontal traversing
mechanism may be included to facilitate manufacturing between components
of SL cabinet(s) and/or alternative manufacturing technologies.
