I do not have any pics of my machine online....but the type of my machine is like this one.
Mine is 12x18 table 25 watts. More than enough power for wood, matt, plastic and acrylics. The input for mine is from CorelDraw artwork. Anything you can draw can be cut and/or engraved.
It is only 2D but I have made many a model with mine.
Another body laser cut on my machine.
More limited than 3-D printer but much more useful than the 'pen' printer.
