36 -- UPGRADE OF STEREOLITHOGRAPHY SYSTEM Sol RFQ 7023-50, Due 043096, contact William D. Rothe (210) 648-3131, Subcontracting Officer. Reference: Subcontract 7018-50. Rothe Development, Inc. is a prime contractor for NASA JSC under Contract No. NAS9-18934. Rothe intends to subcontract on a sole source basis with 3-D Systems, Inc. as the original manufacturer of a NASA-Owned Model SLA-500 Automated Sterelithography System to upgrade this system with the following enhancements. (1) UPG-500 - Provides Orion imaging technology, diode laser leveling, Pentium controller, buildstation software, improved part accuracy and surface finish, up to 46% increased part throughput based on geometry, improved reliability, faster leveling speed, better repeatability, more accurate leveling, and easier vat interchangeability. (2) 500 High Power Laser - Provides a coherent 328 laser with twice the power at the vat than standard laser on the SLA-500 after 2000 hours and increases the build speed by 33%. (3) 500/40 (Zephyr) - The Zephyr recoating system provides easy trapped volume part building, the ability to build at thinner laser (0.004''), faster recoating process, no deep dip and z-wait, 7% performance improvement. (4) QuickCast Software - More user-friendly easy-to-adapt routines with reduced processing times. (5) Resin Upgrade to SL-5180 Epoxy Resin - This is a special upgrade offered by 3-D Systems, Inc. once a year where the customer may upgrade his system to a newer Ciba Geigy resin. The new resin will greatly enhance the mechanical properties of the prototype model (i.e. 10x improvement in part flatness; 40X improvement in green creep distortion; accuracy improvement from RMS error of 0.0089 to 0.0018''). Services: The following services will be required; Hardware Maintenance Plan MWOL - Includes hardware, software, labor, hotline support, travel, and expenses for a one year period. Does not include laser replacement. This includes both periodic maintenance and emergency maintenance. Emergency response is required within one workday. Technical Documentation - Three copies of operations, maintenance, and parts manuals must be supplied. On-Site Training - The vendor shall train 5 employees of the customer in Building 9, JSC, after the upgrade has been installed. Vendors offering comparable upgrade equipment and software must supply complete product information and pricing data indicating exactly what equipment would be offered, the price (including warranty, freight, technical documentation, and training), and customer references. Vendors must bid on all items listed in this solicitation. It is not acceptable to bid only selected portions of this package. No solicitation document exists; therefore, request for such a document will be considered non-responsive and not valid for further consideration. All responsible sources may submit a bid, proposal or request which will be considered. Written responses must be received by the agent at the address specified within 15 calendar days after this notice appears. If no affirmative responses are received within this time to determine that a source is available whose proposal is more advantageous, a delivery order will be placed with 3-D Systems, Inc.
