The 3D Printing Industry: A Revolution in the Making

Before the Boom: The Early Days of 3D Printing

In the early 2000s, 3D printing, or additive manufacturing, was largely confined to industrial settings. Machines costing hundreds of thousands of dollars were used for rapid prototyping, allowing engineers to test designs before committing to expensive production methods like CNC machining or injection molding. The technology was inaccessible to hobbyists, and its potential for scalable manufacturing remained untapped.

The industry began to shift in the late 2000s with the advent of consumer-grade 3D printers. Open-source projects like RepRap democratized the technology, making it possible for individuals to own printers costing as little as $1,000. By 2010, companies like MakerBot and Ultimaker introduced affordable filament-based (FDM) printers, sparking a wave of experimentation among hobbyists and small businesses. However, 3D printing was still seen as a tool for prototypes or small-scale projects, not a viable manufacturing method.

The Turning Point: Accessibility and Innovation

The 2010s marked a pivotal decade for 3D printing. Advancements in materials, such as durable nylons, photopolymers, and composites, expanded the technology’s applications. Printers became faster, more reliable, and capable of producing end-use parts. Industries like aerospace adopted 3D printing for lightweight components, while medical fields embraced it for custom prosthetics and implants. By 2020, the global 3D printing market was valued at $13.7 billion, with projections to reach $63.4 billion by 2026, according to MarketsandMarkets.

This growth was fueled by declining costs. Machines that once cost $250,000 dropped to $300-$400 for consumer models, making 3D printing accessible to entrepreneurs like Kase. The rise of “print farms”—clusters of printers producing parts on demand—enabled small businesses to compete with traditional manufacturers. Kase’s story embodies this shift, showing how one person leveraged affordable technology to disrupt the contract manufacturing landscape.

The Spark: A Closet Printer and a Layoff

Kase’s 3D printing journey began as a side hustle. With no prior experience in additive manufacturing, he was exposed to a rapid prototyping machine in college. Years later, in the early 2010s, he purchased a $1,200 consumer-grade FDM printer, intrigued by how the technology had evolved. Lacking space, he tucked it into his office closet, intending to fund a self-sustaining hobby.

At the time, Kase was working a full-time job, supporting his wife and two young children. Each printer generated $25-$50 daily, enough to cover filament costs and spark curiosity about its potential. His hobby took a serious turn when he was laid off. Faced with financial uncertainty, Kase saw an opportunity to bet on himself. “I had three years of data and a big vision,” he recalls. “Losing my safety net gave me the push to pursue it.”

Scaling Up: From Playroom to Print Farm

Kase’s early setup was humble. Two printers in his closet grew to ten, overtaking his kids’ playroom and tripping electrical breakers. By year three, he was earning $70,000-$80,000 annually, still part-time. The turning point came when he and his wife decided to “go big.” They leased a 10,000-square-foot facility in Houston, moving the operation out of their home.

The business scaled rapidly. Year four saw $180,000 in revenue, followed by $380,000 in year five. By 2024, Kase’s company grossed just shy of $5 million, with projections of $7-$8 million in 2025. Today, his print farm produces 2,000-3,000 parts daily, with peaks of 10,000 parts in 24 hours. Employing 20-30 staff, including summer interns, the operation serves industries from aerospace to women’s fashion.

The Business Model: Contract Manufacturing with a Twist

Unlike traditional manufacturers relying on CNC or injection molding, Kase’s company uses 3D printing for its speed, flexibility, and low inventory requirements. “It gives you the opportunity to iterate quickly,” he explains. “You don’t have to store inventory, so there’s a lot of flexibility.” His clients range from startups needing prototypes to medical firms requiring custom orthotics.

The company specializes in serial and batch production. Serial production involves custom parts, like prosthetics tailored to individual patients, while batch production supports clients with diverse product lines who want on-demand manufacturing. A single 11-hour build on an industrial printer can generate $1,500-$2,500, with margins as high as 70% on some parts.

Strategies for Success: What Set Kase Apart

1. Starting Small and Scaling Smart

Kase’s journey began with a $300 printer, proving that high capital isn’t necessary to enter the industry. He reinvested profits to buy more machines, doubling revenue each year. “The revenue was linearly scalable,” he notes, making it easy to project growth. His advice to beginners: “Start small and don’t try to change the world overnight.”

2. Focusing on Value, Not Just Technology

Kase emphasizes solving problems over hyping 3D printing. “Just because you can 3D print something doesn’t mean you should,” he says. His company targets use cases where additive manufacturing outperforms traditional methods, such as custom prosthetics or low-volume industrial parts. By focusing on client needs, he built a reputation for delivering value.

3. Building Relationships, Even with Competitors

Surprisingly, Kase collaborates with competitors, fostering a sense of camaraderie in a growing industry. “Probably 50% of our competitors, I have the CEO’s number,” he shares. These relationships lead to referrals and knowledge-sharing, helping him secure a 3-5% market share in a sector growing 50% annually.

4. Embracing Automation and AI

As production scaled to thousands of parts daily, manual processes became unsustainable. Kase invested in automation, including an AM Flow machine—one of only a few in the U.S.—that uses AI to identify and sort parts. This technology streamlines operations, ensuring parts are tracked and delivered efficiently.

5. Overcoming Fear and Taking Risks

Fear nearly held Kase back, particularly when transitioning to full-time and investing in industrial machines costing $500,000. “I had to stretch my muscles and get over that,” he admits. Running the numbers and trusting his data gave him the confidence to take on debt and reject acquisition offers, including one for $8 million, when visions didn’t align.

Challenges and Lessons Learned

Power and Maintenance: The Hidden Costs

Operating a print farm is energy-intensive. Kase’s facility consumes as much power as 60-70 households, with electric bills of $15,000-$17,000 monthly. Power outages, common in Texas, can halt production and require costly restarts. To mitigate this, he stocks hundreds of spare parts and maintains 95-98% machine utilization.

Avoiding the Jack-of-All-Trades Trap

Early on, Kase took on every project, spreading himself thin. “It’s hard to be sustainable if you’re an outsider in every industry,” he reflects. He now advises focusing on specific sectors to build expertise and credibility.

Pricing for Value

Underpricing was a costly mistake. On one project, Kase underestimated material costs, forcing him to buy from retail suppliers at lower margins. He learned to price based on the unique value his services provide, even if it meant raising rates and risking client pushback.
