- Department of Commerce, National Institute of Standards and Technology (NIST), Acquisition Management Division, 100 Bureau Drive, Building 301, Room B129, Mail Stop 1640, Gaithersburg, MD, 20899-1640 The National Institute of Standards and Technology (NIST) seeks information from commercial vendors that are capable of providing a piezoelectric drop-on-demand materials deposition printer system. This system will be used to support a time-critical research program to produce standard materials for calibration of explosive and narcotics trace detection instruments deployed throughout the United States in support of Homeland Security. The printer is needed for precision delivery of high-explosive and narcotic solutions on a variety of substrates including floppy disks, simulated luggage, cloth and paper. A critical requirement for this deposition system is the integration of a precision mass measurement capability. After results of this market research are obtained and analyzed and specifications are developed that can meet NIST's minimum requirements, NIST may conduct a competitive procurement and subsuquently award a Purchase Order. If 2 or more small businesses are determined to be capable of meeting the requirements set forth herein, NIST will conduct the complete procurement as a small business set-aside. NIST has a need for a materials deposition printer that would meet the following requirements: Overall System Requirements •The system must be able to dispense droplets-on-demand (in various modes such as single, burst, continuous, and on-the-fly) on media supported on a stage such that patterns may be applied. The stage must be able to support media with dimensions up to 8.5 x 11” and 2” in height. Ejected droplet sizes of 40-60 micrometers in diameter are required for this application. Typical viscosities of the jetted solutions are less than 20 cP. Mass Measurement Functionality Requirements •The station must have functionality that allows gravimetric determination of dispensed droplet mass (mass-on-demand) with a sensitivity of 0.1 ug. This capability must be fully integrated into the instrument control software. This requirement is the most critical for the NIST application. Specific requirements of this functionality are listed below. Gravimetric Functionality Physical 1.A suitable electronic balance must be incorporated that allows mass-on-demand determination of dispensed droplets. This may be the average mass in a burst or continuous stream of dispensed droplets. 2.The resolution of the electronic balance must be 0.1 microgram or below, and be accessible for routine calibration and maintenance. 3.The electronic balance must be rugged and stable enough to withstand the vibrations and stage movements that may normally occur in the system. If recalibration would be required sooner than normally recommended by the balance manufacturer, this must be stated in the proposal. 4.Other than changing weighing boats or performing routine maintenance duties, the user shall not need to modify the station from its normal physical configuration in order to achieve mass-on-demand. 5.Because semi-volatile fluids will be used in the system, evaporative effects will be an issue in the mass measurements. These effects must be controlled and minimized by appropriate design of the system. This may include high-walled weighing boats and vapor saturation chambers, but the vendor is welcome to consider other options. Software 1.Software that controls the electronic balance must be completely integrated into the system software, which must be compatible with MS Windows. 2.If the electronic balance has operating options that include internal refresh rate and stability controls, these must be accessible through the software. 3.Mass-on-demand (MOD) must be a subroutine for inclusion into method scripts, and must have the following user-selected parameters: a.Fluid used (and specific gravity) b.Ejection rate (in Hz) c.Ejection mode (burst or continuous) d.Reading interval (in seconds) e.Number of intervals per measurement f.Measurement table (to select measurement types, such as weighing during stabilization or evaporation or jetting) g.Tolerance (sequential interval weighing stability needed before proceeding to next step in measurement table) 4.Results from mass-on-demand must correct for evaporative effects, and include nanograms per drop, picoliters per drop, and standard uncertainties from the replicated measurements. 5.MOD results must be displayed on the computer monitor in real time, as well as sent to a printer and stored on the hard drive in a suitable format for later retrieval. Hardware Requirements •The sample stage must be able to print on items weighing at least 10 pounds. •Stage travel must be able to accommodate materials with dimensions of 8.5 x 11” and 2” in height. Printable area should be at least 10 x 10 inches. •The sample stage shall have a mechanism to hold samples flat with the stage surface. •Absolute positioning of the stage is required to allow droplet deposition onto selectable areas of various samples. After registration, the system shall be capable of delivering individual droplets within 25 micrometers of a predefined location (at room temperature). •Pneumatic control of the pressure/vacuum system shall be controlled and digitally monitored with a precision of at least 2 mbar. •The printing area shall be fully enclosed to prevent outside contamination of the printed standards. •Vibration isolation of the stage is required. Printing Modes/Software Control •Both vector and raster printing modes are required. •Print on the fly and drop-on-demand modes are required. •Instrument control software must allow for input of user supplied printing arrays/patterns. •The software must allow the user complete control over the printing parameters including adjustment of all waveform parameters. •The system shall be capable of printing dilute explosive and narcotics solutions in water, isobutanol and acetonitrile. Typical viscosities are less than 20 cp with surface tensions of 20-70 dynes/cm. •Vendor must supply documentation that the printhead can produce drops with a drop-to-drop volume variability of less than 2%. A primary use of the printer system is to print dilute solutions of high explosives in isobutanol. If possible, documentation of the drop-to-drop variability should be conducted with isobutanol. •A solid state charge coupled camera system with strobe light illumination is required for visualization of inkdrop formation. •A solid state charge coupled camera for real time visualization of the substrate to be printed is required
