Carbon Raises $60 Million In Funding

Listen to this article

Carbon secured $60 million in funding, marking its most recent capital infusion amid a stabilizing additive manufacturing (AM) sector. Carbon pioneers Digital Light Synthesis (DLS) 3D printing for high speed, scalable production of end use polymer parts in footwear, sports, dental & more. The round drew exclusively from longstanding backers, signaling sustained confidence without new entrants, which underscores the company’s maturing trajectory. Funds aim to accelerate scaling toward cash flow positivity, potentially paving the way for an initial public offering (IPO) within 12-24 months, though market volatility could influence timelines.

Carbon, known for DLS technology enabling rapid, large scale polymer printing, is nearing cash flow positivity through rising volumes and efficiencies. Proceeds will expand capacity, refine workflows, and advance a product roadmap, including sustainable materials. Key wins include Riddell’s NFL topping helmets (six years running) and Fizik’s Tour de France-proven saddles, highlighting production scalability across sports and consumer goods. CEO Phil DeSimone emphasized this as a pivot to “redefine how entire industries bring ideas and products to market.”

Industry Positioning: In a 2025 AM landscape emphasizing high throughput and AI integration, Carbon’s raise stands out as one of the year’s largest, countering funding slowdowns post 2022 peaks. It reinforces bets on polymer AM for end use parts, though challenges like material costs and supply chain resilience persist.

Carbon’s latest $60 million funding round represents a pivotal moment for the Redwood City-based additive manufacturing pioneer, reinforcing its trajectory toward financial sustainability and market dominance in digital light synthesis (DLS) technology. Founded in 2013 by Joseph DeSimone, Phil DeSimone, and Michael Hages, Carbon has evolved from a disruptive 3D printing innovator into a production scale enabler for industries spanning consumer goods, healthcare, automotive, and sports equipment. This infusion, drawn entirely from incumbent investors, arrives as the global AM sector logs 9.1% year over year growth to $21.9 billion, driven by demand for customized, lightweight components amid supply chain disruptions and sustainability mandates. Yet, it also highlights the nuanced investor appetite in a post pandemic hardware ecosystem, where scaling profitability remains the ultimate benchmark.

Carbon’s capital journey mirrors the AM industry’s boom and maturation cycle. The company’s first major raise, a $11 million Series A in December 2013, came courtesy of Sequoia Capital, betting early on DLS’s promise to eclipse traditional layer by layer printing with continuous liquid interface production (CLIP). Subsequent rounds accelerated:

This progression, from venture bets on proof of concept to growth capital for commercialization, illustrates Carbon’s shift from R&D heavy to revenue focused operations. The 2019 round, led by Madrone and Baillie Gifford, valued Carbon at $2.4 billion, a unicorn milestone that drew praise from Sequoia partner Jim Goetz for “cracking the code on 3D printing at scale.” Notably, the 2025 round eschews new capital sources, a pragmatic choice in a venture environment where AM funding dipped 15-20% from 2022 highs due to inflation and interest rates, per industry trackers. Instead, it leverages trust from blue chip backers like adidas, a strategic partner since 2017 whose investment doubles as ecosystem validation.

The funds target a “bridge” to cash flow positivity, a milestone Carbon claims is imminent via surging production (e.g., millions of weekly dental aligners) and process optimizations. Allocations include:

• Capacity Scaling: Bolstering facilities for high volume runs, critical as AM shifts toward “lights out” automation and multi material capabilities in 2025 trends.
• Product Roadmap: Advancing biocompatible, recyclable resins to align with ESG pressures; recent dental and sports applications exemplify this.
• Ecosystem Deepening: Enhancing the Digital Manufacturing Cloud for seamless design to production workflows, reducing time to market by up to 50% for partners.

Phil DeSimone, co-founder and Office of the CEO member, framed the raise as fuel for reinvention: “We have built a remarkable portfolio of products and a network of trusted suppliers, production partners, customers, and collaborators who share our vision.” This resonates amid 2025’s AM emphasis on AI driven efficiencies, where Carbon’s DLS, projecting parts in hours versus days, positions it against rivals like Stratasys or HP in polymer segments.

Partnerships underscore traction:

• adidas: Evolved from prototypes to the fully AM Climacool line, emphasizing breathable lattices for performance footwear.
• Riddell: 3D printed pads in SpeedFlex helmets topped NFLPA safety rankings for six years; expansion to collegiate/high school markets signals mass adoption.
• Fizik/SyBridge: Saddles for elite cycling (e.g., Tadej Pogačar’s Tour de France win) and a deepened service bureau deal for diversified printing.
• Legacy Ties: Ford and Lamborghini integrations from earlier rounds highlight automotive durability testing.

These collaborations have diversified revenue beyond hardware sales (printers, materials) to service models, mitigating AM’s historical margins squeeze.

The AM sector in 2025 reflects cautious optimism: Wohlers reports $21.9 billion in revenues, with polymers (Carbon’s forte) comprising 40% but facing metal AM’s 22% CAGR surge. Funding trends favor scaled players, Carbon’s $60 million ranks among the top five AM raises this year, trailing only AI infused outfits but outpacing pure play startups. Challenges include raw material volatility (resins up 10% YoY) and regulatory hurdles for medical/end use parts, yet opportunities abound in customization: dental alone generates millions of weekly prints for Carbon.

Competitively, Carbon differentiates via DLS’s speed and isotropy, outpacing extrusion based peers in volume (e.g., 10x faster than FDM for midsize runs). However, it grapples with ecosystem lock in, reliance on proprietary materials limits interoperability, a critique echoed in broader AM fragmentation. The raise mitigates burn rate risks, with DeSimone hinting at an IPO in 12-24 months to Axios, potentially valuing Carbon at $3-4 billion if profitability hits. This aligns with public AM peers like Nano Dimension (NASDAQ: NNDM) trading at 5-7x revenues, though macroeconomic headwinds (e.g., U.S. manufacturing PMI at 48.5) could delay.

While bullish, the round tempers exuberance: No valuation bump signals plateaued multiples, and AM’s 2032 forecast ($100B+ market) hinges on adoption beyond prototypes. Geopolitical tensions could hike supply costs, and AI hype might divert capital from hardware. Positively, Carbon’s sustainability angle, recyclable polymers reducing waste 30% versus injection molding, taps green mandates, positioning it for EU/U.S. incentives.

This funding cements Carbon’s AM vanguard status, blending proven scale with profitability pursuits. As DeSimone noted, it’s “an exciting time,” but execution on cash flow and IPO will define legacy in a field where hype has outpaced profits for many.
