Micro 3D Printer

μFAB-3D is an ultra-high resolution 3D-printing system, based on two-photon-polymerization direct laser writing. Compatible with a wide range of polymers, including biocompatible materials, medical grade resins and biomaterials. This system helps to produce any 3D shapes with unprecedented complexity at sub-micron resolution (down to 200 nm-wide features)

Polymer Foaming

Custom made system for supercritical CO₂ and N₂ foaming processes.

Vessel dimensions: 75 mm ID, 25 mm deep. Removable stainless-steel carrier to hold 50 mm diameter samples
Operating pressure range: 80 – 300 bar
Operating temperature range: 20 – 150 °C
Fully automatic pressure & temperature control
Capable of a controlled slow pressure let down, or a rapid depressurization

Ferroelectric Analyzer

Ferroelectric and dielectric breakdown test system with voltage up to ±30 kV/20 mA, frequency up to 10,000 Hz, charge from 1 nC to 10 mC, and temperature up to 250 °C.

General ferroelectric test functions include: Bipolar and unipolar hysteresis hoop, PM – PUND measurement,and FM – Fatigue measurement

This system can measure the electrical charge density of dielectric and ferroelectric materials as a function of electrical field and frequency. Uniquely designed test fixture will not damage soft polymer dielectric materials. Supports dielectric breakdown testing under AC, DC, or field endurance life conditions. Allows automatic ferroelectric testing until dielectric breakdown with features such as automatic frequency scan and automatic voltage scan. Supports both AC and DC poling of piezo materials

Dielectric Test System

Turnkey dielectric spectroscopy measurement from 20 Hz to 2 MHz, temperature from -50 °C to +250 °C, and relative humidity from 30% to 90%. Supports measurement of up to four samples in one run.

Capable of measuring capacitance (dielectric constant), dissipation factor, and other complex impedance parameters of dielectric materials as a function of temperature, frequency, voltage, and environmental conditions

Piezo Strain Measurement System

PolyK Technologies system specifically developed for polymer-based systems.

Features a unique capability to measure force (static blocking force) and dynamic force during displacement. Enables simultaneous measurement of charge, strain, and force versus voltage. It also captures mechanical energy output during actuation — a more critical metric than strain alone
