Santa Maria di Galeria (RM) llaly Ai ENEA Research Center in Porto an Ink-Jet equipment for funcbonai mateiials dposition was Oevetoped and mstalled i nk jet printing is an interesting and versatile technology: it allows funcbonal mat驩riels dposition on diffrent substrates and foiiowing. variable geometry. It is low cosl and does nol need temp驩rature or vacuum. Furtnermore. does not require any contact between dposition System and substrate. In Drop on Demand (DoD) sysfems. drops can be released by ink jet micronead as consquence of piezoelectric actuator ac&vated by an etectr驮c impulse. Impulse imensity and durabon have to be opbmized for each ink to obtain stable drops with volume in the order of 10 pL To obtain lines and surfaces, the right overlap rate among emrtted drops have to be found. so otner parametere to be opfcmized are ink mission frequency and relative speed between printing head and substrate. The equipment hosts maximum four piezoetectric single nozzle printing heads. with aiot'torot! System and a post printing section for UV-IR curing Automatic and manual functions allow funcbonal materials dposition on substrates with maximum dimension 200x200mm Substrate can be in r驩el format, with maximum widtn 250mm. or single sheet. Printing head moves respect the substrate The diameter of dry drop deposited on substrate is in the order of lOOpm. Continuous Unes can be obtained by overlap of drops deposited on demand with opportune frequency. Thanks to extrme versatility. the equipment can be used both for preliminary manual tests and for automatic oprations able to gꩩnrale complicated geometries and multHayer structures Portla Researcn Center: nk Jet printing equipment for Functional materials dposition and flexible substrates or sheetsDunwinder.
