Stop in for a cup of coffee

Been wondering would it be nice to find a place that would scan and make a 3D part reasonably, like a store type place?
Our engineer at work has stuff made here. Shapeways: Industrial 3D Printing Service She makes up the file and they print the parts. They can do the whole thing, but no doubt will cost more. Her stuff is on there as 'Days Mill Designs'
There are imitations in how long a part a particular printer can make...

The problem with 3D printing something that large is keeping the heat evening distributed across the entire surface. Very few if any consumer available printers are going to be able to do that. And I can think of maybe one 3D printer that could do it in the commercial side. And even then, that’s if you could even get the material right now. Nylon and ABS plastics are nearly unobtainable at the moment
Do they have them with multiple print heads? Would think a few overlapping to build a long grill could work.

Good Morning
