MASS PRODUCTION AT HOME.

At the recent Circus Modelers convention in Baraboo, one of the modelers was demonstrating a 3-D printer.

This 3-D printer uses a roll of plastic material that's laid down only in the project itself.  Some of the items it previously produced are available for sale.  There are wagons available in a variety of scales.

It takes a few hours for the figure of an air-calliope player to emerge.  The printer, however, sells for about $1600.  I don't know what design program the operator uses.

A finished air-calliope player (1/24 actual size) is for sale.  In the background is a 1/48 wagon and team with a rubber mule assisting.  Note at lower left a finished 1/87 air calliope wagon and team.
