The post was in response to prior comments about the details that can be achieved with various molding materials and techniques i.e. resin versus injection molded polystyrene. The principal difference between polystyrene and polyurathane resins is one is thermal curing and one is chemical. The molds also differ in that injection molds are Steel or Chrome plated Aluminum versus soft tooling. Soft tools are only good for about 100 pieces. Steel tools are good for 100,000 pieces and can be repolished, plated and reused.
3D printing uses a form of computer tomography to deposit layers of material to build an object. The processs has evolved to utilize a variety of materials; plastics, ceramics, metals etc. CNC has revolutionized machine parts manufacture. 3D printing is revolutionizing molding manufacturing.
3D inkjet printing can paint objects to the same level of color and resolution as the printed page. The processes are highly automated and the per piece cost is low and the quality is high.
Traditionl manufacturing methods for Toy Soldiers employed wood, Cast Iron, ZAMAK and Tin plated Steel; these materials and techniques were replaced by Thermoplastics in the 1950's. Current materals and techniques are in the process of being replaced by 3D printing technology.
The end result will be high quality low cost Toy Soldiers in some cases produced by the collector
using desk top work stations.
