AL Alumina Ceramic
High-Purity Alumina. Micro-Scale Precision.
BMF’s AL ceramic is a 99.99%-pure alumina material processed through a ceramic stereolithography workflow and sintered to 99.5% theoretical density. The result is a part that retains the full mechanical, thermal, and electrical properties of sintered alumina — at feature sizes only achievable through micro 3D printing.
Key benefits:
- High temp
- High strength
- High stiffness
- Chemical resistance

Where Precision Ceramic Performs
Medical Devices Alumina’s biocompatibility, chemical resistance, and hardness make it a well-established material for medical device components. Micro 3D printing enables complex geometries — internal channels, fine features, custom structures — that support next-generation device development and research.
Electronics & RF/Microwave High electrical resistivity (10¹⁴ Ω·cm) and thermal conductivity (32 W/m·K) make AL ceramic well-suited for electronic substrates, insulators, and RF components. Micro-scale printing enables the fine geometries required for antennas, waveguides, and filter structures where conventional machining falls short.
Tooling, Casings & Industrial Compressive strength of 2300 MPa and resistance to chemical attack make alumina ceramic a strong candidate for tooling, housings, and components operating in harsh environments. The ability to print complex geometries without hard tooling reduces lead times for low-volume industrial applications.
