Formula1µ is a rigid, static-dissipative photopolymer resin, engineered for applications where dimensional accuracy, surface consistency, and electrostatic control all need to work together.
BMF Formula1µ is a urethane methacrylate-based photopolymer resin that incorporates a stable dispersion of discrete functionalized carbon nanotubes, known as D’Func technology. This formulation gives the material two defining characteristics: reliable static-dissipative surface resistance, and enhanced mechanical performance across tensile strength, flexural strength, and impact resistance.
Unlike standard photopolymer resins that rely on conductive coatings or additives that can create inconsistencies across a part, the D’Func carbon nanotubes are distributed uniformly throughout the material matrix. This means the static-dissipative properties are stable and repeatable, not dependent on surface treatments that can wear or vary between prints.
The result is a material that behaves predictably under load, resists electrostatic build-up, and holds tight tolerances when printed on BMF’s micro-precision PµSL (Projection Micro Stereolithography) systems.
The combination of micro-precision printing and a mechanically robust, static-dissipative material means that teams working on complex medtech programmes can prototype and validate intricate geometries without compromising on material performance. This shortens development cycles and reduces the number of design iterations required before moving to production tooling.
3D printing in the medical industry has evolved significantly. Where it was once used primarily for anatomical models and surgical planning aids, it is now increasingly applied in the direct manufacture of device components and testing assemblies. Materials like BMF Formula1µ are part of what makes that shift possible, bringing the mechanical and functional properties needed for real-world use.
The material was designed with demanding manufacturing environments in mind. Here is what sets it apart from more generic photopolymer resins.
Consistent Static Dissipation
Electrostatic discharge (ESD) is a real concern in electronics assembly, cleanroom environments, and medical device manufacturing. BMF Formula1µ provides stable, uniform surface resistance across the entire part, not just the outer layer. Because the D’Func carbon nanotubes are integrated into the resin itself, rather than applied as a coating, there is no risk of the static-dissipative properties degrading over time or varying between batches.
Strong Mechanical Performance
The carbon nanotube reinforcement does more than manage static, it actively improves the mechanical profile of the resin. Compared to a standard urethane methacrylate without the D’Func additive, Formula1µ shows measurable gains in tensile strength, flexural strength, and impact resistance. For parts that need to withstand assembly forces, testing, or repeated handling, this matters.
Micro-Precision Capability
BMF Formula1µ is formulated specifically for BMF’s PµSL technology, which is capable of printing features down to 2µm resolution. This level of detail is simply not achievable with FDM or standard SLA systems, and it opens up possibilities for miniaturised components that would otherwise require expensive CNC machining or injection moulding tooling.
Repeatable, Production-Ready Results
For product development teams working towards regulated end-use, repeatability is as important as the initial print quality. Formula1µ is designed to deliver consistent results across print runs, which makes it a reliable material for both prototyping and low-volume production in quality-controlled environments.
Medical 3D printing is one of the fastest-growing areas of additive manufacturing, and the demands placed on materials are increasing alongside it. Best-in-class 3D printed medical tools need to be accurate, durable, and functionally appropriate for their end-use, not just geometrically correct.
BMF Formula1µ stands out in this space because it addresses several requirements at once. The static-dissipative properties are built into the material, not applied as a secondary process. The mechanical performance is meaningfully better than standard photopolymers in the same class. And the compatibility with BMF’s PµSL platform means that resolution and feature accuracy are genuinely at the micro-precision level.
For teams working on the development of medical devices, diagnostic tools, or precision instruments, that combination is difficult to find in a single material. It is part of why BMF Formula1µ has become an important part of what IPFL offers to customers working in demanding end-use environments.
