Improving Ink Jet Printers with MEMS


Published on

Master's students use concepts from my (Jeff Funk) forthcoming book (Technology Change and the Rise of New Industries) to analyze improvements in ink jet printers and in particular the latest ones from MEMS (micro-electronic mechanical systems). See my other slides for details on concepts, methodology, and other new industries.

  6. 6. MEMS device ranges between 20µm to 1mm
  7. 7. Printhead is made up of 11 Integrated Circuit (IC) Chips, with a total of 70,400 nozzles (6,400 per IC Chip) and patented ‘drop triangle’ design
  8. 8. IC Chips are made from Silicon Wafer fabricated by deposition of layer material, patterning via photolithography and then etching to produce the required shapes</li></ul>0.72mm<br />
  9. 9. Technology Paradigm Shift<br />MT5009 - Analysing Hi-Tech Opportunities<br />6<br />Printing Speed: <br />Traditional printer <br />- Printhead scans back and forth as paper is fed through, thus limiting the printing speed as a result. The highest speed that traditional inkjet printer is achieving now is around 30-32 PPM.<br />Memjet printer <br />- Printhead is stationary while paper is fed through. This is made possible by the page wide Memjetprinthead with 70,400 nozzles firing up-to 774 million drops per second, that is about 1 page per second(or 60 PPM).<br />222.8mm wide<br />
  10. 10. Technology Paradigm Shift<br />MT5009 - Analysing Hi-Tech Opportunities<br />7<br />‘Faster’ Printhead : <br />Traditional printer (HP printhead evolution 1985-2006)<br /><ul><li> 360 million drops per second(high-end DesignJet)</li></ul> 170 million drops per second(home & office HP DeskJet)<br />Memjet printer (2008)<br /><ul><li> 774 million drops per second</li></ul>70,400 nozzles/printhead<br />11 kHz nozzle firing rate<br />1600 dpi resolution<br />1.5 picoliter (pl) per drop<br />
  11. 11. MT5009 - Analysing Hi-Tech Opportunities<br />8<br />Technology Paradigm Shift<br />Ink ejection rate and Moore’s Law: <br />By looking at the HP’s printhead development timeline, the ink ejected per second from the printhead doubled every 18 months which is similar to Moore’s Law in the semiconductor industry. <br />Memjet’s Technology (Silicon ICs, 70,400 nozzles, 5 colors) <br />
  12. 12. Technology Paradigm Shift<br />MT5009 - Analysing Hi-Tech Opportunities<br />9<br />Smaller ink drops: <br />Traditional Printer<br />- Around 2-5picoliters per drops.<br />MemjetPrinthead<br /><ul><li>The nozzles on the Memjetprinthead fire ink drops of between 0.6-1.5 picoliters, depending on the firing rate. Lesser volume of ink is achieved with a smaller ink chamber within the printhead and smaller nozzle width of about 12x24µm. The smaller ink drop also allows it to dry up faster and consume less ink.</li></li></ul><li>Technology Paradigm Shift<br />MT5009 - Analysing Hi-Tech Opportunities<br />10<br />Geometric Scaling of Nozzle: <br />Assuming a drop of ink is a perfect sphere:<br />Volume of sphere = 4/3 πr3<br />Any reduction in the width(diameter) of the nozzle will effectively reduced the volume of ink drop by a power of 3 thus reducing the overall usage of ink.<br />Decreasing nozzle size and distance between nozzles will decrease size of print head, thereby reduces cost.<br />Other Aspects of Scaling in Printhead: <br />Ability to add printheads horizontally (Short Edge) to increase printing width and vertically (Long Edge) to increase the printing speed or print resolution.<br />And since there is only one standard-size printhead, there is economies of scale.<br />

  44. 44. Other Business Opportunities<br />MT5009 - Analysing Hi-Tech Opportunities<br />20<br />Devices for Fast Data Transfer: <br />Wide Format Printer – 5 printheads arranged in array<br />High Speed Label Printer – 5 printheads arranged in series<br />A gigabit router(1000Mbps) is used to route the print data file from PC to the individual printhead controller. As the printer gets faster and bigger(beyond the current 5 printheads, larger print data files have to be processed within a shorter time, faster transfer speed will be needed. Optical fiber networking with a transfer rate of upto 100Gbps could be the future solution. Thus, there could be business opportunities for suppliers of optical fiber networking cables, networking switches in the future.<br />
  45. 45. Other Business Opportunities<br />MT5009 - Analysing Hi-Tech Opportunities<br />21<br />New Formulation of Aqueous Ink: <br />At the current printing speed of 1 page(A4) per second, the current ink used in Memjet have to dry up almost instantaneously. This is to prevent ink smudge on the next print-out that will be stacked over the previous.<br />This opens up new opportunities for ink suppliers to work out a new formulation of ink that will be able to dry up much quicker than they are now.<br />
  46. 46. MT5009 - Analysing Hi-Tech Opportunities<br />22<br />Technology Improvement<br />Higher Resolution & Faster Printing Speed: <br />In Memjet’s laboratory testing, the printhead has been found to be able to work at a firing rate of upto 100kHz. However, as the firing rate increases, the drop size will be reduced and print quality will not be optimum at current resolution of 1600x1600dpi. <br />By making the nozzle size smaller, more dots will be able to be squeezed within the 222.8mm overall width of printhead ICs to achieve a higher printhead resolution. Add color redundancy for CCMMYYKK, 8 color channels instead of 5 currently. Provide a more vibrant printout(photo-printing) and dead nozzles compensation.<br />With smaller and more nozzles in future Memjetprinthead, a quicker controller will also be required to drive the printhead to fire more nozzles per second through higher firing rate. <br />Current controller :<br />32 bit RISC controller, 648 MHz CPU<br />
