Hands-on Lab Course | Inkjet Engineering and Inkjet Chemistry
Either qualification and experience in one of the following areas:
The course is open to everybody in inkjet that wishes to broaden their knowledge base: No matter if you are an expert in a specific field of inkjet who wishes to better understand other disciplines, if you are involved in inkjet system integration or in inkjet system operation or if you are a newcomer to inkjet. This course is for you!
The objectives of this foundation course in inkjet engineering and inkjet chemistry are to broaden the knowledge base and to acquire inkjet specific terminology and vocabulary enabling interdisciplinary communication and discussion between the disciplines. The theory sessions are backed up by hands-on lab training. Participants mesure the physical properties and introduce the concepts of material compatibility, pigment dispersions stability and waveform development.
Welcome, course overview, introduction to inkjet.
Terminology, basics on frame construction, axis, drives, sensors, dynamics, resolution, repeatability, quality issues. Introduction to the practical training in the lab. Lab work on material compatibility and printer mechatronics (in small groups guided by training coaches according to lab workbooks).
Core technologies explained and reviewed, print head manufacturers overview, resolution, crosstalk, deviation, drop velocity, drop placement accuracy. Lab work on print heads.
lnkjet System Design
Fluid supply systems, degassing methods, filtering aspects, printing system integration, single pass vs. multi pass, system maintenance. Lab work on ink filtration and degassing.
