Hi there,

I had a look to this kickstarter stuff, that I would like to share : https://www.kickstarter.com/projects/1093108121/sinterhard-metal-filled-filaments-for-3d-printing
The presentation is not really nice, but the content is much more interesting

Process idea: You print your part, you pass it to an oven to remove plastic and sinter the part to obtain a metal part.
It is very similar to what is used for the Mini Metal Maker (http://www.minimetalmaker.com/) but you print directly using PLA/ABS filament

I think it is really something that is missing to bridge the gap with 3d metal printing
