Particle Deposition using inkjet technology prints layers of material in the form of individual drops. Each drop of Solid Ink from Hot-melt material actually prints one particle or one object. Color Hot-melt inks print individual drops of CMYK on top of each other to produce a single color object with 1-3 layers melted together.

Complex 3D models are printed with many overlapping drops fused together into layers as defined by the sliced CAD file. Inkjet technology allows 3D models to be solid or open cell structures as defined by the 3D printer inkjet print configuration. Each method has its own advantages and drawbacks, which is why some companies offer a choice of powder and polymer for the material used to build the object. Others sometimes use standard, off-the-shelf business paper as the build material to produce a durable prototype. The main considerations in choosing a machine are generally speed, costs of the 3D printer, of the printed prototype, choice and cost of the materials, and color capabilities. Printers that work directly with metals are generally expensive.
