Can We Paddle into 3D?

Fabbaloo was recently contacted by a reader with an interesting problem. He's interested in printing a prototype paddle blade.

What's the issue, you ask? The prototype blade exceeds 20 inches in one dimension (the long axis, obviously) and that is, um, slightly bigger than the typical 10" build chamber on most 3D print services. Sure, he could redesign the model to print two pieces and them assemble them, but for a paddle that would be problematic. We know that current 3D prints are not particularly robust, and I wouldn't want to be caught up the creek with a two-piece paddle blade.

Does anyone have a suggestion for our paddle-making friend? Is there a 3D print service that offers build chambers in excess of 20"? Please add a comment if you do.

Seems like a natural job for a CNC machine, using high-density foam or even wood depending on the characteristics desired. Any particular reason why a printer is needed?

Quickparts.com can help address the problem your reader is facing.

In recent years, 3D printing machine manufacturers have rolled out new high-end machines that have expanded the build envelope allowing large parts in a single build.

I have listed the available options below:

SLA (ViperPro) - 25.6" x 29.5" x 21.65" in
SLS (SinterStationPro HiQ) - 15" x 13" x 18"
FDM (900mc) - 36" x 24" x 36"
Objet (Connex500) - 19.3" x 15.4" x 7.9"

You can have your reader contact me directly and I can put him in touch with the appropriate person.
