摘要
A projector or system for assisting in a removal of 3D printed molds from a print chamber. The projector is operative to receive a file in a format compatible for a 3D printer. The projector further receives input corresponding to a location of the prototype contained in a powder box and input corresponding to a profile of powder contained across a surface of the associated powder box. Using the location, a portion of the prototype located immediately beneath a surface of powder in the powder box is determined. A distance of the portion to a selected region of the top surface is also determined. A cue is generated based on the distance. The projector generates an image of the extracted layer and projects the image onto the surface of the associated powder box. The image comprises at least one color coded region within a proximity of the portion, where a color of the color coded region is based on the cue.
