UV curable inkjet technology combines the characteristics such as noncontact

facile operation

low cost

no residue of solvents after UV curing

and environmentally friendly of inkjet technology with UV curable system. It has been widely used in braille printing

fabrication of ceramics and electronic devices

manufacture of the textiles

and the modification and protection of the wood surface. The key material in the technology is the UV curable inkjet ink formulated by UV curable monomer

prepolymer

photoinitiator

additives

and assistant. According to the different demands of applications

some functional materials such as metal

metal oxide

carbon nanomaterials

and quantum dot have been added into the ink. UV curable inkjet technology has been used in the fabrication of solder resist layer. The technological difficulty is the adjustment of the adhesive force. The coating should stay on the surface during the etching process

and the layer should be easily moved thoroughly after etching. It is of great significance for the further extend and optimization of the UV curable inkjet technology to learn about key factors and the corresponding adjusting strategy for its application in additive manufacture.
