** Selective Laser Sintering (SLS)
 +
*** Cost: Very High
 +
*** Tech: High-power lasers fuse any meltable material, from plastics up to metals like titanium.
 +
*** Advantages:
 +
**** Produce replacement parts on demand for your fighter jet on an aircraft carrier.
 +
**** Fused material might be recyclable.
 +
*** Disadvantages:
 +
****See Cost.
 
** Ink-Jet Powder+Binder
 
** Ink-Jet Powder+Binder
 +
*** Cost: Medium
 +
*** Tech:  Lays down layers of powder and "prints" the design using a glue-like binder.
 +
*** Advantages:
 +
**** Can do colour.
 +
**** Model structures are self-supporting via unused powder.
 +
**** "Green" parts can be infused with materials from glue to molten metal to strengthen.
 +
**** Unused powder can be reused.
 +
*** Disadvantages:
 +
**** "Green" parts are fragile.
 +
**** Hollow parts will trap binder if no exit holes are designed in.
 +
**** Fabricated objects may be difficult or impossible to recycle back into machine inputs.
 +
** Fused Deposition Modeling (FDM)
 +
*** Cost: Low
 +
*** Tech:  An extruder head deposits melted material (like plastic) or pastes to build up an object layer-by-layer.
 +
*** Advantages:
 +
**** Cheap.
 +
**** Can be completely hollow and air-tight.
 +
**** Can be vestment-cast with molten metal.
 +
**** Simple machine design.
 +
**** For thermoplastic and similar materials, fabricated objects can be melted back down and reused.
 +
*** Disadvantages:
 +
**** Large overhangs require support material.
 +
**** Multiple colours and/or materials require complex multi-head extruder designs.
