To all SUNLU colleagues, family members, partners, and shareholders:
Twelve years ago, we set out with a simple belief: that 3D printing could make creation easier. At the time, this technology still felt distant to most people, but we saw its limitless potential—it shouldn’t be confined to professional domains, but should become the hands that bring every creator’s dreams to life. Today, as we stand at the threshold of SUNLU’s 12th year, we want to share with you how those early beliefs, through the persistence of countless individuals, have transformed into the tangible reality we now see.
Because We Believe in Our Users, We See the Power of Creation
"Simplify Creation" is not just a slogan we say—it is a mission embedded in SUNLU’s very DNA. Because we are committed to being user-centric, we have spent over a decade perfecting high-precision filaments with a tolerances as tight as ±0.02mm. Looking ahead, we will continue to invest heavily in the research, process optimization, and equipment upgrades for FDM filament, striving steadily toward our goal of becoming a leader in the FDM filament industry. At the same time, we are increasing investment in resins and peripheral electronic products through independent R&D and manufacturing—such as our latest AMS Heater—and will continue to expand into related supporting projects as the time comes.
Hearing our users' frustrations with complex workflows, we’ve introduced detachable spools, spool-less filament options, and our flagship line of engineering filament. Through the years, each new iteration has been guided by the steady hand of craftsmanship and precision. From precision-fitted medical prosthetics to university innovation tech competitions, from developing sustainable materials to building school-enterprise partnerships—we are witnessing technology break through barriers, stepping out of papers and labs, and gradually becoming a productivity tool accessible to everyone.
Because We Believe in Perseverance, We See the Value of Time
We remain committed to a spirit of truth-seeking and pragmatism. Even as the industry went through its downturns, we chose to stay grounded and focus on refining process stability. To ensure a reliable supply chain, we’ve continued investing in our three major production bases in East China, South China, and Vietnam—now operating 160 production lines with an annual capacity of 20,000 tons. We’ve come to see that channeling our resources into sustainable competitiveness is the only way to uphold our promise to users through all challenges.
Because We Believe in Openness, We See Shared Growth
“If you want to go fast, go alone. If you want to go far, go together”. Guided by the principle of “integrity and mutual success,” we continue to connect with like-minded partners. We've established an Engineering Technology Research Center for 3D Printing Materials and Equipment, transforming user feedback into multiple product upgrades. Our Germany Operations Center provides localized support to meet the needs of European makers. We’ve come to see that when the entire industry chain advances in unison, 3D printing can truly move from factories into homes, and from laboratories into everyday life.
Because We Believe in the Future, We See the Edge of the Morning Light
At this very moment, we are turning belief into action—committed to advancing the entire industry, doing what is difficult but right, and delivering high-quality, problem-solving products to our users. In our talent development strategy, we uphold a creator-centered philosophy that encourages breakthrough innovation. At the same time, we optimize our global services through simplicity and efficiency, making creation more seamless than ever.
Dear friends, the twelve years of SUNLU have been shaped by the footprints of countless believers walking side by side. Your unwavering demand for quality drives us to never slack off. The trust of our partners has carried us through industry cycles. And the resilience of every SUNLU team member—those who have paused, gone deep, and made things happen—has brought the visions born in the morning light closer to reality.
The road ahead still requires us to move forward with humility and perseverance. But we’ve never forgotten: because we believe that technology is meant to serve people, we now see creators across the globe; because we believe in the power of putting down roots, we now see the forest that time has given back.
Thank you for walking this path with us. In the future, let’s continue to believe—and see even more possibilities together.
