About this file
This is a Statement of Requirements document for software to support multi-laser metals-based powder bed fusion additive manufacturing systems at the National Institute of Standards and Technology (NIST). The software must support development of information models using EXPRESS Language and incorporate ISO 10303 AP242/AP238 packages for modeling, customization, and implementation of technology-specific extensions. Key technical requirements include support for slicing 3D geometries into 2D areas and exporting to Common Layer Interface format.
The contractor must deliver the software electronically within 30 calendar days of award, provide remote installation assistance, and deliver 4 hours of training for up to 4 people within 30 days of software delivery. The contract includes a 1-year warranty for software problems. This is a firm-fixed-price contract that will be awarded on a Lowest Price Technically Acceptable (LPTA) basis. The system will undergo acceptance testing by NIST for up to 14 business days before final acceptance. The contract is overseen by NIST's Engineering Laboratory Systems Integration Division, which has led a working group since April 2021 to develop information models for laser powder bed fusion processes.

Software for Multi-Laser Metals-Based Powder Bed Fusion Additive Manufacturing System
Background:
Additive manufacturing refers to a class of emerging manufacturing technologies for producing highly-complex, customized components by joining materials to make objects based on three-dimensional (3D) model data, typically built layer upon layer. Parts are fabricated directly from a 3D computer-aided design (CAD) file that is virtually sliced into many thin layers and sent to an additive manufacturing (AM) system where each layer is incrementally formed. Several AM processes and systems have been developed over the past two decades and their capabilities have grown significantly. Generally, metal-based additive processes form parts by melting or sintering material in powder form until all layers are completed.
Additive manufacturing is capable of manufacturing parts that are not possible to make with conventional machining. For example, additively manufactured parts can be fabricated to have highly complex geometries, engineered porosity, and lattice structures. Complex geometries allow components to be designed and built as one part, as opposed to being incorporated in an assembly. Engineered porosity is popularly used in medical or biological applications, because the porous structure promotes osseointegration, the direct structural and functional connection between living bone and the surface of an implant. Lattice structures are popular due to their high strength-to-weight ratios. Figure 1, shown below, contains two examples of parts that cannot be manufactured with conventional machining processes. Another advantage of additive manufacturing is that parts are directly produced from a digital 3D model of the part. This makes the process well suited for the quick manufacture of customized parts. High throughput additive manufacturing builds on these principles with additional considerations such as faster processing times, increased automation, and more streamlined processes achieved through advances in areas such as processing technology, sensor-based process monitoring capabilities, and process modeling and simulation capabilities.
Scope
The purpose of this requirement is to procure a software system to formalize the development of the consistent interpretation of additive manufacturing of metal parts. The software will be used to develop an EXPRESS model for communicating the geometry build parameters for the fabrication of an additively manufactured part in powder bed fusion systems.
Minimum Technical Requirements
The Contractor shall provide a software system that meets all technical specifications identified below.
Software & Data Access considerations
• The software shall support development of information models using the EXPRESS Language
• The software shall incorporate ISO 10303 AP242 and AP 238 packages for modeling support.
• The software shall support the customization of ISO 10303 AP242 and AP 238 packages for technology-specific extensions.
• The software shall support the customization of ISO 10303 AP242 and AP 238 packages for technology-specific implementations.
• The software shall support the export of custom technology-specific implementations into the Common Layer Interface format.
• The software shall support the slicing of 3D geometries into two dimensional (2D) areas using ISO 10303 AP242 and AP238 representations.
Delivery
Delivery of the software shall be conducted electronically within 30 calendar days of award.
Remote software installation assistance shall be provided by contractor as needed.
Training
The contractor shall provide a minimum of 4 hours of training for up to four (4) people. The training shall provide a thorough demonstration of all software functions. The training shall include hands-on exercises as part of the instruction. The training shall include electronic copies of training materials and related information, including (but not limited to) training handouts and operator manuals. The training may be completed virtually or at NIST immediately after setup and installation but shall be completed no later than 30 calendar days after delivery.
Inspection & Acceptance
The successful contractor shall test the integrated system and demonstrate its ability to meet the minimum technical specifications to NIST. NIST reserves the right to independently test the installed system before acceptance for a period not exceeding 14 business days.
Warranty and System Maintenance
The contractor shall provide a warranty for 1 year to resolve any software problems discovered.
