Acutally, the PacMan image was a bitmap. I didnt' convert it to vector.. I converted it to B&W, and printed it in 3d mode.. It took white as the highest point, and engraved everything else according to darkness.. Vector art does tend to come out more clean, however.
As far as clear materials go, the laser has an autofocus feature, in which it brings the bed up to the point where it touches the laser, then focuses on the nearest surface, clear or not.. the engraving of Pacman in this picture was done with the paper OFF the lexan..
We will only have the machine for another month or so, as it is for an ENTIRELY different project, however, we're willing to use it to give cab builders the Personal Touch on their cabs while we have it.
IF anyone is interested, like I said, e-mail me at mgerety@snet.net and let me know what you want to do, and i'll give you a price estimate... We MAY get another engraver, but it's not definite, so if anyone wants custom Lexan etching, wood engraving, or custom metal badges for their cabs, speak now, or forever hold your peace (Maybe). ;-)
