Three Dimensional Printing (3DP)

The name is a bit confusing, since it doesn’t give any insight into the process, but 3DP is the term used to describe  Z Corp’s technology, which they employ in their line of ZPrinters.

The machine uses a bed of powder and a print head. The print head dispenses a plastic resin which binds to the powder and solidifies it. It spreads on a layer of powder with each new print layer.

Like SLS, the unsolidified powder stays in the workable area so support structures are unnecessary.

Z Corp’s claim to fame on their printers, though, is their ability to color the resin as the machine prints. This means that one model can be printed in any combination of colors; it is even precise enough to print text into an object. Taken from the Z Corp website:

In addition, it can print moving parts the same way that FDM can. The quality of the finished models is rough compared to other technologies, though the parts can be machined afterwards.

Advantages?
• 24-bit color system…
• Prints moving parts.
• No supports necessary.
• Relatively fast printing time.

Disadvantages?
• Rough finish.
