- RFQ with SOW, Drawings, & T&Cs STATEMENT OF WORK 1.Objective This statement of work defines the requirements for fabrication of a propulsion module demonstration part using Selectively Laser Melted (SLM) Titanium-6Al-4V. The requirements include quality documentation and SLM build details. Criteria is also provided to assess the current state of the art for SLM Titanium-6Al-4V for each vendor, which will be used to support the award selection. The details are provided in the sections below. The goal is to use the propulsion module builds to optimize the design and SLM processing for a larger follow on 6U CubeSat technology demonstration test article. 2.Characteristics and Requirements The contractor shall perform the following: Build Requirements 1.The contractor shall additively manufacture three (3) propulsion modules per 3D model MER1779. Minor adjustments between builds should be allowed for optimization. 2.The part shall be final machined and to meet the dimensions provided in drawing MER1779. 3.Ti-6Al-4V powder shall be of ELI grade and meet the composition standards defined in ASTM F3001. 4.The following witness test specimens shall be included with the primary part build. Location and orientation of the specimens shall be approved by MSFC. Specimens shall be thermally processed with the primary part except as noted below. Witness Specimens •Z Tensile: QTY = 4 (represent full height of build) •XY Tensile: QTY = 2 (1" above Table base) •Metallurgical: QTY = 2 (represent full height of build, 1 as-built removed prior to thermal processing and 1 with completed part) 5.The propulsion module shall be Hot Isostatic Press (HIP) per an established process to produce a high density quality part. 6.The contractor shall verify all internal passages are clear of powder prior to exposing the part to liquids or any heat treatment operations. 7.Parts shall have no cracks or other defects per visual inspection. Consult customer if there are any suspicions of defects. 8.Any support structure added by contractor shall be approved by MSFC. Support structures shall be removed prior to delivery. 9.Any anomalies during the build process of the final part shall be reported to MSFC. 10.As-Built surface finish shall be media blasted condition. Quality Documentation Requirements (Provided with Part) 1.Verification of build orientation and location within the build box. 2.Machine Type and model. 3.Purge gas used in chamber environments (purity levels). 4.Laser Speed and Power. 5.Layer Thickness. 6.Powder lot data, chemistry (per ASTM F3001), and manufacturer. If blended powder is used for build, provide data on proportions of virgin to used powder & sieve size for cleaning. 7.For each build powder lot provide definition as defined in ASTM B243 for the following: type, shape, particle size distribution. 8.Provide record of post-build finishing. 9.Heat treat record and oven temperature traces. Contractor Selection Approach and Criteria The contractor selection will be based on cost, schedule, and the use of a defined metallurgical process. The metallurgical process should consist of fundamental material and process control parameters that are used to produce the desired microstructure and properties. This includes powder feedstock, fusion process parameters and post-build thermal treatment. The contractor shall provide the following information to support an assessment of the current metallurgical process. Note that the use of a qualified metallurgical process is not required for selection. The intent is to assess the vendors SLM Ti-6Al-4V build process without costly testing and acceptance requirements for the demonstration hardware. The use of a specific Quality Management System compatible with aerospace suppliers will also factor into the selection process. •Manufacturing Control Plan •Powder control specification •Specification on fusion process controls and build pattern plate used for verification •Consolidation quality/as-built density •Stress relief and hot isostatic press (HIP) heat treatment experience and control •Micrographs of evolving microstructure through each phase of thermal treatment and microstructural acceptance criteria •Evidence of basic mechanical performance through tensile properties (ultimate strength, yield strength, elongation) and high cycle fatigue performance (if available) •Metrics describing the surface texture and rendered detail characteristics of the process •Established reference or standardized part that is used to verify performance of the machine. 3.Place of Performance Selected contractor facility 4.Period of Performance Fabrication shall be performed August 21, 2017 through December 16, 2017.
