High-speed Camera for Meltpool Imagining

I. Introduction/Background:

The Production Systems Group (PSG) at the National Institute of Standards and Technology (NIST) conducts research in metal-based additive manufacturing (AM) with the goal of improving process monitoring, control, and qualification of AM processes. A key platform supporting this work is the Additive Manufacturing Metrology Testbed (AMMT), a laser powder bed fusion research system developed at NIST to study the relationship between processing parameters, melt pool dynamics, and resulting material properties. The AMMT platform enables precise synchronization between the laser position and in-situ monitoring devices, including high-speed cameras used to capture melt pool dynamics during the laser–material interaction. These measurements provide critical information for understanding the AM process and improving process stability and part quality. The system is currently being upgraded to AMMT 2.0, which incorporates a dual-laser configuration to enable studies of coordinated laser processing, transient melt pool dynamics, and process control strategies under multi-laser operation.

II. Purpose:

The purpose of this acquisition is to procure one (1) monochromatic, silicon-detector-based high-speed camera for melt pool imaging in the AMMT 2.0 dual-laser system.

All items must be new. Used or remanufactured equipment will not be considered for award.

Experimental, or prototype will not to be considered. The use of “gray market” components not authorized for sale in the U.S. by the proposer is not acceptable. All line items shall be shipped in the original manufacturer’s packaging and include all original documentation and software, when applicable

III. Minimum Requirements:

For the laser powder bed fusion additive manufacturing in-situ monitoring, the camera needs to have a combination of speed, resolution, sensitivity, and controllability. Specifically, the contractor shall provide a quantity of (1) camera, meeting the following minimum specifications.

Sensor type: CMOS Color: Monochrome Pixel pitch: Less than or equal to 18 μm x 18 μm Bit depth: 12-bit or better Resolution: 1.2Mpix or larger Sensitivity: > 30 % Quantum Efficiency (QE x FF) @ 850 nm; > 60 % @ 550 nm.

Shutter: Global shutter Minimum shutter speed: Less than or equal to 1 microseconds Data transfer protocol: CoaxPress or 10 Gb ethernet Onboard memory: 72 G or larger, able to partition and download while recording Lens Mount: Must come with c-mount adapter

Frame rates: Greater than 10,000 fps at full resolution Greater than 100,000 fps at a sub-window size 120 x 120 pixels or above.

Triggering: Random external TTL triggering capability with frequency up to the maximum sample rate for the defined resolution.

Dimension: Not to exceed 130 x 130 x 150 mm to fit within laboratory space constraints at NIST.

IV. Installation/Training/Site Preparation: N/A

V. Delivery:

Delivery shall be FOB destination and shall occur within the vendor’s standard commercial lead time, but no later than 4 weeks after contractor receipt of order. FOB Destination means: The contractor shall pack and mark the shipment in conformance with carrier requirements, deliver the shipment in good order and condition to the point of delivery specified in the purchase order, be responsible for any loss of and/or damage to the goods occurring before receipt and acceptance of the shipment by the consignee at the delivery point specified in the purchase order; and pay all charges to the specified point of delivery.

Due to the current campus access restrictions at NIST, delivery shall occur at a mutually agreed upon date between the contractor and the NIST subject matter expert (SME). The contractor shall NOT deliver any items until the delivery date has been agreed upon in writing, and the contractor has received written approval from the NIST TPOC to proceed with delivery. Contractor failure to acquire written approval from NIST prior to shipping products shall release the Government of any liability and may result in the delivery being disallowed onto NIST’s campus. All items shall be delivered to the following address:

NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY (NIST)

Shipping and Receiving

100 BUREAU DR

GAITHERSBURG, MD 20899

The camera will then be delivered to the location it shall reside at, located at:

NATIONAL INSTITUTE OF STANDARDS AND TECHNOLOGY (NIST)

B108, Building 233

100 BUREAU DR

GAITHERSBURG, MD 20899

NIST is a controlled-access facility, therefore delivery personnel must be a U.S. citizen or a U.S.

permanent resident.

VI. Inspection and Acceptance:

In addition to the inspection and acceptance terms articulated in 52.212-4, The Government reserves the right to perform such performance tests and evaluations as defined below to verify specified system performance. Such tests and evaluations, if performed, shall be conducted within the environment in which the system is to be operated. The Contractor has the right to be present during the tests and evaluations, if performed, at the Contractor’s expense.

The scope of general inspection included:

1. Structural, mechanical, and electrical evaluation of product

2. An operational evaluation of the High-speed camera

3. Evaluation of the system’s performance and software interfacing

A visual inspection of the High-speed camera will be performed by the NIST SME to identify defects or any form of indication that the High-speed camera was damaged during transport to NIST. The Government shall have sole discretion to require repair or replacement of damaged and/or nonconforming supplies at no cost to the Government. The Government at any time prior to acceptance shall reject the High-speed camera due to defects and/or nonconformance.

The vendor is responsible for latent defects discovered any time after final inspection. However, the extent of its liability shall be prorated over the useful life of the High-speed camera.

The place of acceptance shall be:

100 Bureau Drive Building 233 Gaithersburg, MD 20899

Ownership (title) of the High-speed camera shall transfer to NIST upon acceptance.

VII. Warranty

The contractor shall warrant the entire system in accordance with the contractor’s or original equipment manufacturer's (OEM) standard commercial item warranty.

VIII. PAYMENT SCHEDULE

The Contractor shall be paid, in accordance with Net 30-day payment terms, upon receipt and acceptance of a proper invoice, in accordance with the following schedule:

1. 100% after receipt and acceptance by the Subject Matter Expert (SME) and Designated Government Official (DGO) of a fully delivered system.

2. The Government anticipates inspection will occur upon:

a. After the testing procedures set forth in this document have been completed.

NOTE: Partial shipments and partial invoices will not be accepted, unless otherwise requested and accepted by the Contracting Officer prior to award offer. Proposed payment schedules shall be submitted with vendor’s response to the RFQ for consideration.
