Abstract
A unique modified formula of hot-melt ink for phase change
printing process was developed. A composition useful for
3D printing comprises different waxes, tackifier and
plasticizer resins, rheology modifiers, and UV curable resin
and/or gas releasing agent. Differential scanning
calorimetry was used to evaluate thermal properties of the
ink components and the extensive study of the thermal
behavior of the proposed gas releasing agents has been
carried out. The rheology behavior of inks and printability
such as image detail, definition of dots (sharpness of the
edges), dot formation, and spreading were investigated. Dot
heights were measured by a modified method using a First
Ten Angstrom dynamic contact angle instrument.
Sutherland Rub resistance test was also used together with
