The Rapidia metal 3D printing system uses a water-based metal (or ceramic) paste. This bound metal process requires no debinding as the water evaporates during printing, and the printed object is ready to go into the sintering furnace immediately. The process also saves about 90% of the metal used by other bound metal systems for building rafts and supports. A wide range of metals is available.
The printer holds up to four paste cartridges, out of which two can be printing at any given time. Most objects can be printed without any support, freeing up the support printhead for another material. Using the water bonding process a complex object is printed without support as several parts. Parts are joined simply by wetting the joint line. After sintering, it becomes a single part.
The Rapidia system is the most office-friendly of all systems available today, as it uses no solvents except water and plugs into a standard single phase 220-240V 50A outlet, the same outlet used for an electric range in a kitchen. It is also the most ecological system as there is no removed binder to dispose of.
