RE: 3D Printing Technology: Making It Faster and Cheaper
Great post @doitvoluntarily! You are absolutely right, printing metal objects is the next step in 3D printing! Plastic parts is very nice but very often you will need metal for strength and endurance!
Printed metal parts are not that dense. Maybe further down the line they could match the strength of a forged metal.
If you factor in some overdimension and sinter the parts after printing you could achieve higher densities.
