The Best 3D Printing Stocks for September 2025
3D printing has matured from futuristic hype into a real driver of manufacturing transformation. The global additive manufacturing industry grew to nearly $21.9 billion in 2024, up 9.1% year over year, according to the Wohlers Report 2025. Healthcare, aerospace, and industrial applications continue to lead adoption, while consolidation in the sector has created a clearer group of leaders.
Here are six 3D printing stocks worth watching right now.
3D Systems (DDD)
3D Systems has been working through a multi-year restructuring, and in its Q2 2025 earnings release the company reported net income of $104.4 million, a sharp turnaround from a year-ago loss, alongside improved liquidity. However, revenue declined 16% year-over-year, reminding investors that growth remains lumpy.
Why it matters: As one of the original pioneers of additive manufacturing, 3D Systems remains a central player in medical applications and advanced prototyping, but competition and uneven revenue growth mean it trades as a turnaround story rather than a pure growth play.
Stratasys (SSYS)
Stratasys has been under pressure from activist investors, but its Q2 2025 earnings showed progress: $138 million in revenue and adjusted EBITDA of $6.1 million, alongside raised full-year guidance. With a cash-rich balance sheet and strong aerospace and automotive clients, Stratasys remains one of the most stable players in polymer 3D printing.
Why it matters: The company has the balance sheet to weather market softness, but merger speculation continues to add volatility.
Proto Labs (PRLB)
Proto Labs hit a new revenue record in Q2 2025, posting $135.1 million in sales, up nearly 10% year-over-year (Digital Commerce 360). The company’s diversified model—offering 3D printing, CNC machining, and injection molding—makes it a one-stop shop for rapid prototyping and short-run production.
Why it matters: Proto Labs trades more like an industrial tech company than a pure-play 3D printing stock, making it appealing to investors who want exposure without the volatility of hardware-only firms.
Desktop Metal (DM)
Desktop Metal once symbolized the promise of mass-production 3D printing, but in July 2025 the company filed for Chapter 11 bankruptcy while pursuing a sale of foreign subsidiaries. While its binder-jetting technology remains innovative, investors face enormous uncertainty around restructuring and survival.
Why it matters: This is now a highly speculative play. Investors seeking stability in additive manufacturing should look elsewhere.
Materialise (MTLS)
Belgium-based Materialise reported in its Q2 2025 results that revenue from its healthcare segment grew 16.7%, offsetting weakness in industrial demand. The company also launched Magics 2025, the latest version of its widely used additive manufacturing software.
Why it matters: Materialise is a software and services play rather than a hardware company, giving it recurring revenue and strategic partnerships across medical device and industrial customers.
Nano Dimension (NNDM)
Nano Dimension’s Q1 2025 earnings showed 8% revenue growth alongside narrowed losses, with $840 million in cash reserves to fund acquisitions and R&D. The company specializes in additive electronics, allowing on-demand PCB printing and other niche applications.
Why it matters: Still speculative, but its cash runway and unique technology give it optionality in a consolidating industry.
