Requirements Document – Additive Manufacturing System

Introduction This document defines the minimum technical and performance requirements for an industrial-grade additive manufacturing (3D printing) system. These specifications ensure fair competition while meeting Government mission needs.

Minimum Technical/Performance Requirements

- Build Volume: Minimum 400mm x 400mm x 300mm.

- Machine Dimensions: Approx. 750mm (H) x 670mm (W) x 830mm (D).

- Supported Materials: Must be capable of printing with carbon- and glass-fiber reinforced polymers (e.g., PA12-CF, PA12-GF, PETG-CF) as well as flexible materials.

- System Weight: Approx. 80–85 kg (175–185 lbs).

- Print Bed: Rigid aluminum tooling plate (or equivalent) with automated leveling capabilities.

- Production Speed: Capable of sustained high throughput printing (minimum 1 kg/day;

objective 2 kg/day).

- Motion System: Precision closed-loop servos or equivalent, achieving high accuracy and repeatability.

- Chamber Control: Actively managed heated and cooled chamber to ensure print stability across environmental conditions.

- Power: Standard 120V AC input, maximum draw ~1000W.

- Print Head: Capable of reaching up to 500°C nozzle temperature.

- Print Bed Temperature: Capable of heating to at least 130°C.

- Chamber Temperature: Capable of heating to at least 60°C.

- Resolution: Z resolution of 1.5 μm or better; X/Y resolution of 25 μm or better.

- Rapid Print Speed; max:1100 mm/s, continuous 1000 mm/s

-Print Speed; max: 500 mm/s, continuous: 300 mm/s

- Acceleration; max: 40,00mm/s² in X/Y axes, continuous: 10,00mm/s² in X/Y axes

-Volumetric Flow Rate @ 0.4mm nozzle; Max: 45mm3/s, continuous: 25 mm3/s

- User Interface: Touchscreen HMI with connectivity options including CANBUS, Wi-Fi, and

USB.

- Maintenance: Designed for low-maintenance operation, targeting less than 1 hour per month during 24/7 production use.

- Durability: Rigid structural frame with metal enclosure capable of long service life under industrial production loads.

- Warranty: Minimum coverage for motion system, electronics, and manufacturer defects consistent with industry standards.

Critical vs. Desired Features Critical Must-Have Features:

• - Large build volume (≥ 400mm in any axis).

• - Ability to print with high-strength fiber-reinforced polymers.

• - Active chamber management (heating/cooling).

• - High temperature nozzle (≥ 500°C).

• - High bed temperature (≥ 130°C).

• - Closed-loop precision motion control.

• - High throughput (>1 kg/day production).

• - Industrial-grade durability and reliability.

Nice-to-Have Features:

• - Touchscreen HMI with multi-protocol connectivity (Wi-Fi, USB, CANBUS).

• - Extended maintenance intervals (≥ 10X industry average).

• - Low-cost consumables and spare parts.

• - Enterprise-level support packages with 24/7 availability.

• - Advanced monitoring (remote diagnostics, sensors, etc.).

Interoperability and Compatibility Requirements The system must be compatible with standard additive manufacturing workflows and Government-approved software environments. Requirements include:

- Ability to process standard AM file formats (e.g., STL, OBJ, AMF, 3MF).

- Connectivity via common network protocols for integration into enterprise systems.

- Compliance with DoD cybersecurity requirements when networked.

- Ability to export production and maintenance logs for Government oversight.

Conclusion This requirements document defines the salient technical characteristics necessary for a high-performance additive manufacturing solution, while remaining brand-agnostic in compliance with FAR 6.101 and FAR 11.105. Vendors may propose any system that meets or exceeds these specifications.
