Form / Attachment / Pricing Sheet

This document provides the item description and specifications for ET Metal Powder Sieving Vacuums, requested by the 76 CMXG for fund utilization.

• Item: Metal Powder Sieving Vacuums (3 units total: 1 SPC – ATEX, 2 SPC).
• Functionality: Powder reclamation system designed to remove, collect, and sieve hazardous and reactive metal powders (nickel, cobalt chrome, aluminum) from GE Concept Laser M2 Series 5 printers.
• Integration: Must interface with the printer's integrated vacuum port and overflow hopper outlet.
• Automation: System should automatically extract powder, transfer to a buffer hopper, and dispense onto a sieve with controlled feed rate.
• Components: Includes two vacuum hoses, powder conveyor system suitable for specified alloys, interchangeable sieve sets (75-micron for nickel/aluminum, 63-micron for cobalt chrome per system).
• Processing: Must be capable of sieving under an inert gas atmosphere. Features dual agitation methods (ultrasonic and vibratory) and ultrasonic knocker to prevent powder bridging. Includes integrated scales for measuring waste and reclaimed powder. Requires automated powder feed from buffer hopper to sieve.
• Safety: System for aluminum processing must be explosion-proof and compliant with ATEX Zone 20 (or equivalent). All systems require CE or UL certification.
• Manufacturer Requirements: Minimum of five (5) years' experience producing comparable systems. Must provide redacted customer references from the past twelve (12) months.

This document details the specific technical requirements and performance standards for the metal powder sieving vacuums. Bidders must ensure their proposed equipment meets all listed specifications, safety compliance, and manufacturer experience criteria to be considered responsive.

Other / Unclassified

This document is a Brand Name Justification for the procurement of three (3) powder reclamation systems. These systems are required to support the REACT facility's operations and interface with existing GE Concept Laser M2 Series 5 metal Laser Powder Bed Fusion (LPBF) 3D printers. The systems are designed to remove, collect, and sieve hazardous and reactive powders (nickel, cobalt chrome, and aluminum alloys) generated during metal 3D printing.

This document outlines specific, brand-name required characteristics for powder reclamation systems. Key features include:

• System Functionality & Interface: Standalone units that vacuum extract residual powder from build platforms and hoppers, interfacing directly with the GE Concept Laser M2 printers.
• Powder Handling & Processing: Automated transfer to a buffer hopper, sieving with controlled feed rates, return of reclaimed powder for reuse, and collection of coarse particles in a waste container.
• Atmosphere & Safety: Sieving must occur under an inert gas atmosphere. Systems handling aluminum must be explosion-proof (ATEX Zone 20 compliant or equivalent) and hold CE or UL safety certifications.
• Conveying & Sieving Mechanisms: Must include a powder conveyor system suitable for heavy/reactive metals with interchangeable sieve sets (75-micron for nickel/aluminum, 63-micron for cobalt chrome).
• Agitation & Flow: Dual agitation methods (ultrasonic and vibratory) and an ultrasonic knocker to prevent powder bridging.
• Measurement: Integrated scales for measuring waste and reclaimed powder.

The justification highlights that manual processes increase exposure to hazardous powders and result in severe health and inhalation risks. Automated systems are stated to mitigate these hazards, improve operational efficiency, and reduce machine downtime. Market research indicated that commercially available systems lack the integrated vacuum conveying and sealed powder handling architecture required for closed-loop inert gas operation with reactive AM powders, necessitating additional equipment and custom integration. The document concludes that a specific brand name is required due to these circumstances.
