Post-Machining for Metal 3D-Printed Parts in Aerospace and Defense

Metal additive manufacturing (also known as metal 3D printing) can create complex geometries that are difficult to produce through machining alone. But many printed components still need precision machining before they are fully ready for assembly or use. 

Focused on Machining helps aerospace, defense, space, and other advanced manufacturers turn near-net-shape 3D-printed parts into finished components that meet final specifications.

Experienced Support for Metal Additive Components

We started machining metal 3D-printed parts many years ago; in fact, one of our oldest customers is a 3D printing company. Our team has a long history with the unique demands of post-machining additive parts. 

Our work includes machining sealing and mating surfaces, threaded holes, bores, and other tight-tolerance features that printing alone can’t always achieve. 

Metal additive projects for industries like space often use materials that are difficult to machine, like titanium and Inconel. We regularly perform Inconel and titanium machining for both traditional and 3D-printed components; our team has the experience to handle them confidently.

Why Post-Machining 3D-Printed Parts Can Be Difficult

A printed part presents different challenges than bar stock. Additive manufacturing can produce features like internal passages and thin walls, which may create important benefits for performance. But those same features sometimes make a component difficult to hold or access during machining. 

Careful workholding and cutting strategies are critical. And many of these components are very high value, so we have to machine the required feature without risking scrap.

These factors make communication and documentation between a manufacturer and customer very important to success. Whenever possible, we recommend you provide CAD models for both the as-printed part and the finished component, as well as drawings, material specifications, and inspection requirements. This helps our team design a strong process, and in some cases we’ll be able to catch issues before we start cutting.

5-Axis Machining for Complex Printed Geometries

We’re able to take on these challenges because we’ve built our operation around complex work. Our advanced CNC equipment, led by our 5-axis machining capabilities, lets us reach features at multiple angles in fewer setups. 

This is especially important for parts such as impellers and other intricate components. Our team always develops tooling and machining strategies around the individual geometry instead of trying to force these parts into a standard process.

A Qualified Partner for Aerospace and Defense Programs

In addition to our technical capabilities, Focused on Machining is AS9100D and ISO 9001:2015 certified and ITAR registered. As of October 2026, we have also completed a CMMC Level 2 self-assessment covering all 110 requirements and are preparing for a third-party assessment.

Combined with our experience machining titanium, Inconel, and complex geometries, they make Focused on Machining a strong partner for customers with programs in demanding industries like aerospace and defense.

Share your documents and program requirements, and our team will help determine the right approach for turning your printed part into a production-ready component.

Scaling Complex Aerospace and Defense Manufacturing Programs

At Focused on Machining, we’re proud of our ability to produce complex, tight-tolerance components with our true 5-axis machining and other capabilities. But just as important, we are always prepared to expand our capabilities and capacity as a customer’s program grows.

Over the past several years, we’ve proved repeatedly that we’re ready to help aerospace and defense customers by investing in new equipment when their production requirements call for it.

Case Study: Investing in a Complex Component

About a year ago, a customer approached us with an extremely complex metal 3D-printed part that needed full-5-axis machining. We proved out a machining process and manufactured it successfully, and they were happy with our results. 

The program grew and the customer needed significantly higher volumes. But their next order came with a quick timeline, and our capacity was filled on the machines involved.

We didn’t just accept this bottleneck; instead, we wanted to take major steps to help them meet their goals. We ordered a new multi-axis lathe with live tooling, along with an additional coordinate measuring machine (CMM). This equipment will not only support this program, but it will also expand our capabilities for future aerospace and space projects.

The new lathe will initially be dedicated to this component, creating the production capacity needed for the growing program. And the CMM will significantly accelerate inspection, so we can maintain quality standards while moving parts through production more efficiently.

How We Support Our Customers 

We were willing to make this commitment in defense and aerospace machining because we view our customers’ growth as an opportunity to evolve alongside them. When a customer trusts us with a long-term program, we look beyond the current order and consider what will be necessary to enable success over the long-term.

This is not a new approach for our precision machine shop. Several years ago, one customer’s designs started to grow in complexity. Parts that once required only one or two machining operations began requiring three to five. 

Because of those changes, we saw an opportunity and invested in a 5-axis machine. That decision allowed us to serve the customer more effectively while building capabilities that opened the door to additional long-term programs, including work for defense prime contractors. 

The Next Steps in Building Capabilities

Our latest equipment purchases follow the same philosophy: we’re helping our customers today while thinking of their needs tomorrow, as well. The new multi-axis lathe is being acquired with an immediate program in mind, but we chose a machine with capabilities that can handle more than the current part.

The lathe has both live tooling and multi-axis capability, which will let us complete complex turned and machined features in fewer setups. Once the current program’s needs slow down, that capacity will also be available for future projects.

You can have confidence that we’ll do what it takes to support your future production, whether that’s higher order volume or greater complexity. We can collaborate with you to understand what it will take to scale successfully.
