Technology / product information

Ultra-fine 3D printing technology leverages the world's highest precision 3D photolithography to enable prototyping of intricate components such as microlenses, diffractive optical elements, microneedles, and MEMS. Castem, in collaboration with Kyoto University of Advanced Science, offers contract fabrication services utilizing this technology. With a resolution as fine as 0.2μm, it enables the production of shapes and precision levels previously unattainable with conventional methods.

■ Key Features
High-precision fabrication: Achieves a minimum resolution of 0.2μm, enabling the creation of detailed structures and complex shapes.
No mold required: Eliminates the need for molds or machining, allowing for cost and time-efficient production, even for single prototypes.
Fast delivery: Supports rapid prototyping with a turnaround time of just three weeks.
Material versatility: Utilizes resins such as IP-Q, IP-S, and IP-Dip, allowing for material selection based on heat resistance and mechanical properties.
Optional services: Offers additional options like dry plating (materials: platinum, etc.) and microphotography for added functionality and analysis.

■ Specifications
Printing modes: Supports LF, MF, and SF modes for tailored solutions based on application needs.
Substrates: Compatible with silicon, ITO, silica, and other substrate types.
Heat resistance: Depending on the resin used, the printed parts can withstand temperatures ranging from 242°C to 371°C.
Minimum size: Fabricates features as small as 0.2μm in the XY direction and 0.3μm in the Z direction.
Maximum size: Supports fabrication up to 15mm × 8mm in size.

■ Applications
Micro-optics: Fabrication of hemispherical microlenses with smooth surfaces.
Biomedical engineering: Prototyping microneedle arrays with sharp tips for medical applications.
Microfluidics: Production of nozzles with undercut interiors that are challenging to create via machining.
Biomimetics: Recreating biological structures, such as an ant at actual size, based on CT scans for biomimicry research.
Photonics: Manufacturing ultra-fine lattice structures for photonic applications.

Ultra-fine 3D printing technology enables the fabrication of microstructures that were previously difficult to achieve, opening new possibilities in research, development, and product prototyping.
