ATARU Black — High-Temp DLP Resin

ATARU Black by Nano Dimension is a groundbreaking UV-curable resin for DLP printing. Part of the ATARU series, it combines exceptional high-temperature resistance, durability, superior surface quality, and ultra-low dielectric loss with enhanced precision down to the printer's pixel size.

Key Benefits

• Market-leading thermal performance — HDT >300°C (0.45 / 1.8 MPa), Tg >300°C
• High impact strength and durability; suitable for injection molding
• Ultra-low dielectric loss — ideal for high-frequency / RF applications
• Enhanced precision — excellent accuracy on fine features, scalable after post-processing
• Low viscosity (~885 mPas) — seamless integration across a wide range of 365–405nm DLP printers
• Fast processing, suitable for serial production

Ideal Applications

• Connectors for electronics
• Molds (injection molding)
• Tools & fixtures
• Radio frequency (antenna) components
