Seurat Technologies Starts Mass-Producing Metal Parts With Area Printing

Seurat Technologies, the Wilmington, Massachusetts company that licensed its metal printing process from Lawrence Livermore National Laboratory, says it has reached the milestone it was built for: full-scale production of customer parts. The company's Area Printing system, which melts patterned tiles of metal powder rather than scanning point by point, is now running at its first production facility and delivering commercial parts.

How Area Printing Works

conventional laser powder bed fusion machines fire a laser at one tiny spot at a time, building a layer before moving to the next. Seurat embeds a pixelated pattern directly into the laser beam, melting 3-to-10-millimeter tiles in a single pass. Because the system fires many tiles simultaneously, the company says its process runs 12 to 40 times faster than conventional LPBF. Speed depends on how many tiles are fired per layer, not how many points the laser visits, which means dense geometries and complex features carry no extra time penalty.

The result is a fundamentally different cost equation. Seurat says it can produce T-nuts for under $1 each, threads printed directly into the part with minimal post-processing. A machined equivalent costs between $1.50 and $5 at similar volumes, and the design flexibility of subtractive manufacturing imposes its own limits. The company is also running heat exchangers with sub-200-micron features, industrial flow components, and specialized fasteners for consumer products.

From Prototype to Production Floor

Reaching production rate took longer than the initial concept. Commissioning the first Gen1 production printer required 10 months from subsystem integration to first print, then another four months to move from that first print to actual commercial parts. The second Gen1 system came together much faster: three months to first print, a few more weeks to commercial production. That learning curve matters, because it shows the process is repeatable, not a one-off lab result.

CEO James DeMuth says the focus now is operational excellence. "It is been very exciting for us, having those production systems really cranking away," he said. The company is qualifying all three machines for high uptime while running customer work concurrently. Cash generation and repeatability are the immediate metrics.

The Print Depot Vision

Seurat does not see itself as a printer company. The long-term plan is a network of standardized Print Depots located near major customers, each housing 16 to 32 machines. These facilities would function as an extension of a customer's supply chain: software-defined metal part capacity that shifts between products and materials without retooling. Smaller localized batches replace the traditional model of large centralized production followed by global shipping.

For aerospace, defense, and industrial customers waiting on metal parts, the appeal is lead time. Seurat says a nozzle ring it now produces costs the same to 3D print as to conventionally machine, but the time savings are significant enough that the customer calls it market-changing. The company currently runs steel parts and plans to add aluminum and titanium as its Powder Station infrastructure expands.
