Unique binder-based 3D printing technology was developed at MIT. ExOne uses Binder Jetting technology to 3D print complex parts in industrial-grade materials. Binder Jetting is an additive manufacturing process in which a liquid binding agent is selectively deposited to join powder particles. Layers of material are then bonded to form an object. The printhead strategically drops binder into the powder. The job box lowers and another layer of powder is then spread and binder is added. Over time, the part develops through the layering of powder and binder. Binder Jetting is capable of printing a variety of materials including metals, sands and ceramics. Some materials, like sand, require no additional processing. Other materials are typically cured and sintered and sometimes infiltrated with another material, depending on the application. Hot isostatic pressing may be employed to achieve high densities in solid metals.

Binder Jetting Process
Binder jetting
A printhead selectively dispenses binder on a
thin layer of powder. Powder layers can be
spread by a counter-rotating roller from a
supply chamber to the build chamber, or the
powder can be spread by a recoater. After the
part is completed, the build chamber is
removed to a curing oven, after which the part
is depowdered and prepared for sintering or
infiltration.
Advantages
Economics are great. Well suited for large
parts. All kinds of powders can be used.
Support structures are not needed.
Disadvantages
Surface finishes are generally ~400 microinch.
Post-processing such as sintering is necessary
for processing metals, ceramics, and other
materials.

Droplet Interaction with Powder
Analogous to inkjet paper printer:

3DP is Basic Powder Metallurgy
Bonded
Partially Sintered
Infiltrated
Highly Sintered
Powder metallurgy is the
process of blending fine
powdered materials, pressing
them into a desired shape or form
(compacting {printing}), and then
heating the compressed material
in a controlled atmosphere to
bond the material (sintering). The
powder metallurgy process
generally consists of four basic
steps: powder manufacture,
powder blending, compacting,
and sintering. (Wikipedia)
