Ok here we go
Purpose: 3d micro/nanofabrication of collagen matrixes via multiphoton excitation.
What this means: A laser is driven by two mirrors attached to galvanometers and controlled by labview. When the laser passes over the collage (several times) it becomes crosslinked. The result is a potential micro scale cell scaffold that has potential in tissue engineering.
The goal: As of now we have limited capabilities for creating 3d structures. Lines rectangles and circles are easy enough but anything larger..or deeper requires the movement of an xyz stage which is also controlled by labview. The goal is to be able to be able to simply create an object in autocad (or a similar product) output the file to labview and run the galvanometers, which incidentally, move according to how much voltage is passed through them.
Ideas: Let's say we wanted to create a sphere. The laser only has one plane of focus so to create a 3d object requires slicing. Divide the sphere up into several hundred slices, which, when stacked loosely resemble a jagged sphere. Slicing can be done in a program called Magics RP. This is where the .stl file comes in. From magics rp we should be able to get an .stl file that describes the coordinates of these slices (in ascii or binary format) and from here transfer the job over to labview.
Problem: NO IDEA how to go about doing that last step. Does labview have anything built in to handle .stl files?? Any advice appreciated.

jimbo2,
You may want to try Motion Assistant. It has the ability to read in a file of points and contour (spline) through them. You can get a free 30 day evaluation copy from the web. If it works, by a copy of Motion Assistant. If the .stl file format doesn't work with Motion Assistant, post again and we can see what other ideas exist.
Thanks,
Rodger.
This link should take you to a webpage where you can learn about and download Motion Assistant.

you could use the Load STL File.vi from the picture control toolset

May I ask how you were able to make "Lines rectangles and circles" controlling a laser and galvo with labview? Do you use a vision software utilizing matrices?
