The Reason

When interest rates are cut, money tends to flow into industrial companies and smaller growth orientated businesses. These are often some of the first beneficiaries of cheaper borrowing costs and looser financial conditions.

Now, if the U.S. is serious about reshoring manufacturing and limiting its reliance on immigration to fill labor gaps, then one technology becomes essential: 3D printing.

Why? Because 3D printing enables distributed, scalable manufacturing. Making it possible to create complex, customized parts quickly, cost-effectively, and right where they’re needed. This capability improves efficiency while it also reshapes entire supply chains, reduces risks, and allows for innovations that traditional simply manufacturing can’t deliver.

Why This Drives Growth

Think about what businesses need most today: speed, flexibility, and resilience. 3D printing helps in all three.

• On-demand production and local manufacturing: Instead of waiting weeks for shipments from overseas, companies can make parts near the point of use. This cuts down on lead times, lowers transportation costs, and reduces the need for excess inventory.

• Complex and custom part manufacturing: Industries such as healthcare, aerospace, and automotive increasingly require specialized designs. 3D printing allows for customization at scale, giving each industry a competitive edge.

• Advances in materials and automation: With new metals, bio-based plastics, and even AI-driven optimization, 3D printing is expanding beyond simple prototypes into critical, high-performance applications.

• Supply chain resilience: In a world where disruptions are common, a distributed production model makes manufacturing more adaptable and reliable.

In short, 3D printing is not just about making things differently, it’s about making industries stronger, faster, and more innovative.

How It Works

3D printing, also known as additive manufacturing, builds objects layer by layer from a digital design.

Here’s the step-by-step process:

1. A design is created using 3D modeling software.

2. That design is “sliced” into thin horizontal layers and translated into printer instructions (called G-code).

3. The printer then deposits material (plastic, resin, metal, or powder) layer by layer onto a build platform.

4. Each layer bonds to the one below until the full object is complete.

The key advantage here? Less waste, faster turnaround, and the ability to manufacture shapes that traditional methods can’t produce.

Industries Already Using 3D Printing

• Aerospace: Lightweight, high-strength metal parts and rapid prototyping.

• Medical/Healthcare: Implants, prosthetics, dental devices, and surgical models.

• Automotive: Custom components, tooling, and prototyping.

• Industrial Manufacturing: Fixtures, machine components, and low-volume production parts.

• Consumer Goods: Jewelry, eyewear, and custom small-batch products.

Where Adoption is Headed Next

• Construction: Houses, infrastructure, and large-scale components made directly by 3D printers.

• Healthcare/Bioprinting: Tissue engineering, organ printing, and personalized medicine.

• Aerospace & Defense: Mission-critical components for aircraft and unmanned systems.

• Electronics: Printed circuit boards and micro-devices.

• Energy & Utilities: Complex turbine parts and offshore construction solutions.

Cast of Characters

We just saw a monumental year in nuclear energy stocks, and 3D printing may follow a similar trajectory. As this theme develops, it’s wise to get familiar with the major players. They’re likely to be at the center of one of the most important growth stories of the next decade.

$VELO ( ▲ 4.89% ) - Velo3D – A recently re-issued stock given a lifeline from SpaceX, Highly speculative, but lines up with the right time and place for something like this to work. Velo3D specializes in advanced metal 3D printing for industrial applications, particularly aerospace. However, the company recently faced financial stress and risk of bankruptcy and has since re-organized. Its largest early investor, SpaceX, stepped in with an $8 million licensing and service agreement to keep operations going. While this underscores both Velo3D’s technological value and financial fragility, it also highlights the strategic importance of its technology for industries like space and defense.

***When investing in growth stocks, it’s important to recognize that secondary offerings, when a company issues additional shares, are a normal and expected part of the process.

Yes, these offerings dilute the value of the shares already in circulation, which can feel discouraging in the short term. But they serve a vital purpose: raising the capital companies need to fund operations, expand their business, and move closer to profitability.

Think of it this way: for growth companies, issuing more shares is like fueling the engine before the car can run on its own. Instead of viewing it as a red flag, expect it as a natural stage in the journey of a company that’s still building its foundation.
