I have a makebot 2 3d printer at work.. maybe i should print one out
I think that would be a fun project to try.
I worked at a place where I had access to a laser that could cut acrylic sheet material. I was tempted to try but there was a lot of work involved. After parts were cut out they had to be cleaned before being able to glue together, keeping them in order, alignment, sculpting down the contours to a smooth continuous body line and then the thing had to be finished so it wasn't just a chunk of sanded plastic resembling a car. I was also more concerned about wear / damage to the machine I couldn't afford to fix or compensate for if there was some real profit making project that came along if the machine was down.
The 3D printer eliminates a lot of the labor if you can get around wear and tear issues I'd go for it.
The term "model" was confusing at first. Wasn't aware that 3Ds Max was an AutoDesk product. I've been using AutoCAD for over 25 years and have done some crude 3D "models" using it but it can't do anything like the pics you've provided. Very, very nice work by whoever did them.
