Proto Labs is widely regarded as the world's fastest digital manufacturing platform — and in 2025 it proved why investors love it. The company posted a record $533 million in annual revenue, up 6.4% year over year, while earnings per share jumped from $0.66 to $0.88. For 2026, management projects another 6%–8% revenue increase and is implementing structural efficiency improvements to build a more scalable operating model. Unlike pure hardware vendors, Proto Labs earns recurring revenue from every part it produces across industries including medical, automotive, aerospace, and robotics — a model investors are rewarding with premium multiples.

Why it stands out

• Platform model generates ongoing revenue from every manufactured part — not just printer sales
• Over 700 million parts produced for 300,000+ customers since inception
• Diversified across medical, automotive, aerospace, and robotics end markets
• Management actively targeting operational scale and margin improvement in 2026

Every 3D printed part starts as a CAD file — and PTC makes the software that brings those files to life. The company has been a longtime technology partner to manufacturing and industrial enterprises, offering 3D printing CAD software alongside augmented reality, industrial IoT, and product lifecycle management tools. With most of its revenue subscription-based, PTC generates ample and predictable free cash flow. In Q1 2026, it delivered $686 million in revenue and $267 million in free cash flow — exceptional numbers that underscore why software margins (70–90%) structurally beat hardware margins (20–40%). PTC's fiscal 2026 EPS guidance of $4.42–$6.93 reflects a business firing on all cylinders.

Why it stands out

• Subscription-first model provides stable, recurring revenue that compounds over time
• Software captures value from the entire additive manufacturing ecosystem without hardware risk
• Diversified into AR and industrial IoT — reducing dependence on any single technology trend
• Strong profitability with full-year 2026 EPS projected at $4.42–$6.93

Stratasys is the original pioneer — co-founder Scott Crump patented the fused deposition modeling (FDM) technique that underpins modern 3D printing. After the sector-wide boom and bust of the early 2010s, the company has endured and is actively improving. Management's cost-savings initiative is working: adjusted EBITDA margin expanded from 4.5% in 2024 to 5.2% in 2025. The company's Q4 2025 revenue grew 16% sequentially, beating its own guidance. Recent milestones include Subaru adopting Stratasys technology to accelerate automotive tooling, a new SAF qualification program with aerospace giants Boeing, Northrop Grumman, and Raytheon, and a launch of a dental anatomical model solution that delivers up to 300% faster production with one-day turnaround versus five days traditionally.

Why it stands out

• Partnership with Subaru using new T25 High Speed Head for F770 printer in automotive tooling
• SAF qualification program underway with Boeing, Northrop Grumman, and Raytheon for aerospace
• Dental and medical innovations including 3D-printed anatomical training models launching in 2026
• Cost discipline is working — margin expansion is consistent and accelerating
