3Dresyn HP1 BTO70 High Permittivity resin with ferroelectric, pyroelectric, and piezoelectric properties

3Dresyn® HP1 BTO70 is a high-permittivity photopolymer formulation based on Barium Titanate (BTO), engineered for advanced dielectric and functional electronic applications. The material is supplied as a free-flowing paste containing high dielectric ceramic loading, enabling the fabrication of components with elevated relative permittivity using SLA, DLP and LCD 3D printing workflows.

This formulation enables the design and manufacturing of functional dielectric devices with controlled electrical behavior across RF and microwave frequency ranges.

Designed for use in advanced additive manufacturing systems (SLA, DLP and LCD) within research, electronics and high-frequency engineering environments requiring controlled dielectric properties.
