Recoating Module
IPM
The recoater system has a Zephyr ™ recoater blade with four axes of motion: The y-axis moves
the recoater blade front to rear; the z-axis moves it up and down; the theta y-axis tips or rotates the
blade about the center; the x-axis motion directs sensor motion on the blade. The recoater
system’s liquid level sensor maps the resin surface by moving around the resin surface. The
sensor calibrates the position of the blade so that the blade moves perfectly parallel to the resin
surface, enabling the build to be accurate and precise. The recoating system uses the motion axes
that are connected to the blade, enabling the system to self-calibrate and permitting a customized
setting of the blade gap, or distance from the blade’s bottom to the resin surface, for different
resins.
The iPro 8000/9000 SLA Center’s IPM (Image Projection Module), directs the laser beam using
directional, focusing optics, and scanning mirrors, along with an AOM (Acoustical Optical Modulator)
to regulate the output power. This process will accurately reproduce the input CAD data one layer
at a time.
