How is Filamet™ used?
Print and Polish
In some uses, simply printing and polishing items gets the job done.
The high metal content in Filamet™ (90+%) means that once it's polished, everything that's visible on the surface is pure metal. Prints will age, patina, oxidize, etc. just like the metals they are infused with. Since the surface is pure metal after polishing, it becomes indistinguishable from a pure metal print. It's cool to the touch and has the proper weight.
Sinter for a Pure Metal Object
Some uses require a firing process to remove the binders from the final print leaving a high purity metal object.
Using The Virtual Foundry's products and processes, anyone with a desktop 3D printer can print pure metal at a fraction of the cost, in a fraction of the time. Companies find tremendous advantage in the low cost and quick production cycle realized by using The Virtual Foundry method.
When viewing Filamet™ under a microscope, it's very easy to understand why it works. Quite simply, there is so much metal in it that metal is the only thing visible. There is just enough plastic in it to make the metal particles stick together. Filamet™ does not require special hardware, it works in any FDM (the most common) printer on the market today.
