RE: [rp-ml] Stl for CNC and spray on fiberglass

Jonathan,

Yes, there are machining softwares that can handle .STL files, while others
cannot. Of those that can, some can handle large data sets (such as
generated by an optical digitizer), while others are limited in polygon
count.

An additional way to make the transition from .STL to a CAD-based
surface/solid is to surface or solid model the .STL file. This increases
the number of CNC packages that will be able to machine off the data.
Again, there are softwares that accomplish this "conversion" very
effectively, and others that require a tremendous (i.e. prohibitive) amount
of labor. Of those that accomplish the task effectively, the quality of the
surface is a factor in the amount of time required to create the CAD model.
The quality of the CAD model translates into machining time and the amount
of hand-finishing necessary, and again, portability between CAM packages.

Please contact me with any questions.

Subject: [rp-ml] Stl for CNC and spray on fiberglass

List,

Can anyone give me the lowdown on what might (or might not) be required for
getting an stl file into a CNC-friendly format?

I have a series of stl's and was interested in taking four of them and using
them for CNC output of the file.

Is a conversion necessary and if so, does it depend on the type of machine,
geometry of the file or what exactly.

I'd be interested in knowing if there are any technically savvy CNC outfits
in the Austin/Texas area as well.

**********

This is a little off-topic, however does anyone know where I might find good
information/techniques/case studies for applying a large scale fiberglass
type surface to a frame or armature?

Can I spray-on fiberglass using a conventional paint gun?

Are there other material combnations that I should look at?

Much thanks,

Jonathan
