When going from CAD (SolidWorks??) to prototype on the bumper stuff, are you RP'ing the bumper in sections, or did you actually have a mold made and lay it up?
Thank you.

We go from solid model to a full scale machined-foam part, to use as a positive plug for mold creation. This plug gets touched up by hand using the sculpted part as reference, then handed off to the mold-maker for surfacing. He then creates the mold from it to produce the final part.

Here's an example of this process with the rear quarters:
machined plug before touch up
and the plug during machining

For the bumpers, we'll print critical contour sections in 1/2 scale and a 1/8 scale complete bumper to check proportion and shape before committing to full scale foam. (Hopefully this will reduce the 'touch up' time after machining.)

We learn as we go!
