Hardware
XY Translator
The XY translation system is based on a design implemented by Ilan Moyer in his Foamcore CNC project. It is a remarkably simple design that derives precision from the stepper motors that drive each axis.
Laser Shutter Mechanism
The optics mount and shutter mechanism consists of a piece of machined Teflon rod that receives the terminus of the laser fiber optic cable and guides the laser into a microscope objective, producing a narrow, collimated beam. This beam is subject to a cable-actuated shutter made of Teflon that allows simple control of the laser output.
Powder Distribution Mechanism
The powder distribution hardware is responsible for managing the reservoir of print powder and spreading new layers of the powder over the print platform.
