Aerospace, defense, and medical device manufacturers are already running EOS metal additive manufacturing in production. The question for most operations isn’t whether the technology works. It’s whether it works for their parts, their volumes, and their workflow. This article covers the three things manufacturers ask about most: what materials are available, what Phillips brings to the partnership, and what economics actually look like at real production volumes.

Materials: More Than Most Manufacturers Assume

Most manufacturers assume Metal AM means one or two materials. EOS systems are validated against more than two dozen, with process parameters tuned for the highest quality builds.

Metals

• Stainless and tool steels. 316L, 17-4, and Maraging Steel MS1 for corrosion resistance, hardness, and cost-effective structural applications.
• Aluminum. AlSi10Mg for strength-to-weight ratio and thermal performance.
• Titanium. Ti64 Grade 5 and Grade 23, high strength and corrosion resistance, including biocompatible applications.
• Nickel superalloys. IN718, IN625, and HAYNES® 282® for parts that need to hold up at extreme temperatures.
• Specialty metals. Copper Cu, Invar, Tungsten, and others for more challenging applications.

The right material depends on load, temperature, corrosion, and weight, not which one is easiest to quote. Part geometry plays a larger role than most manufacturers anticipate. Overhangs, internal channels, wall thickness, and support structure volume can all shift the decision. That is what Phillips Application Engineers sort out before a simulation ever runs.

Polymers

EOS polymer systems cover biocompatible, flame retardant, high performance, flexible, multipurpose, and mineral-filled materials including PA11 and PA12. For applications where metal is not required, EOS polymer systems deliver the accuracy and repeatability that production demands.

What Phillips Brings to the Partnership

EOS is the global technology and quality leader in industrial 3D printing, with more than 30 years of experience in Direct Metal Laser Sintering and Selective Laser Sintering. Phillips Corporation is an authorized EOS reseller operating across the Mid-Atlantic, Southeast, and South-Central United States, with regional offices in Maryland, North Carolina, Pennsylvania, and Arkansas.

The Phillips Additive team provides Application Engineering support before and after the sale.

The Metal AM Production Simulation

Before any client commits to EOS technology, Phillips Additive runs a Metal AM production simulation built from their actual part files. It is not a demo.

• Real part geometry, not a generic test piece
• Multiple run scenarios, small order versus weekly production cadence
• Materials compared side by side when more than one could work
• Full cost breakdown: capital, operating, and material, separated out
• Engineering risks flagged upfront, including supports, design tweaks, and multi-laser thresholds

The simulation is free. A decision built on real information is better for both sides.

Ongoing Engineering Support

Phillips Application Engineers guide your simulation and material selection, advise your support strategy and first production runs, and stay available as your volumes or parts evolve. If support removal runs long, a part needs a design tweak, or volume justifies a multi-laser system, the Phillips team is already at the table, not a number you have to chase down.

The Economics: What Production Actually Costs

Metal AM economics are volume-dependent. A small trial run carries the full weight of machine time with very little volume to spread it across. In one simulation Phillips ran on the EOS M290:

• 2 parts per build: $164 per part
• 14 parts per build: $89 per part
• 51 parts per build, full nest, unattended overnight: $61 per part

Same machine. Same material. Same hourly rate. Just better math as volume increases.

The Three Cost Components

• Capital expenditure. Machine cost amortized across its operational life. Fixed regardless of part count per build.
• Operating expenditure. Hourly cost covering power, argon gas, build plates, recoater blades, and consumables. Also fixed per hour regardless of nesting density.
• Material cost. Per-kilogram powder cost, which varies by material and scales with part volume and support structure requirements.

Because capital and operating costs are time-based, not part-count-based, a fully nested build at the same runtime as a sparse one costs the same to run but produces a significantly lower per-part figure.

Layer Thickness as a Throughput Lever

Running 316L at 80 micron delivers significantly faster cycle times than 40 micron, though at the cost of some surface resolution. Finer layers roughly double build time for higher resolution at the same hourly rate. For most production parts, 80 micron is the right call. The production simulation maps this curve for your specific parts so the trade-off is grounded in real build data.

Unattended Runtime

The EOS M290 runs unattended overnight and across weekends. For tight production schedules that means more output without adding headcount or overtime, which is a significant part of what makes high-volume nesting scenarios so economically compelling.

Make vs Buy

For manufacturers currently outsourcing complex metal components, the simulation provides the foundation for a genuine make versus buy analysis. Capital, operating, and material costs across different utilization levels, compared directly against current supplier pricing. That comparison is often what moves the conversation from evaluation to decision.

Where to Start

Metal AM is not the right answer for every part. But for complex, low-to-mid volume metal components that are causing friction, whether from supplier lead times, machining difficulty, or material sourcing challenges, it is worth knowing what the technology would actually cost for your specific operation.

The production simulation is free, built around your parts and your volumes, and delivers a clear picture before any commitment is required.
