THE SHORT LIST: 5 Med-Friendly Materials

Developing medical devices or health care components? Here’s five good material options to consider.

PEEK, PEI (Ultem) and PPSU (Radel). Attributes: High temperature resistance, creep resistance and works well for applications that require sterilization.

Polycarbonates (Makrolon and LEXAN HP1). Attributes: Good clarity with clear and translucent applications, good impact resistant, and durability.

Medical-grade LSR.

Medical-grade liquid silicone rubber (QP1-250). Attributes: Thermal, electrical and chemical resistance, biocompatibility, and is suitable for skin contact.

Titanium (Ti 6-4). Attributes: Lightweight, temperature and corrosion resistant 3D printed metal used with direct metal laser sintering (DMLS) process to produce fully functional medical components.

WaterShed XC 11122.

WaterShed XC 11122. Attributes: ABS-like material used to 3D print clear microfluidic parts with sterolithography (SL) process. Resistance to water and humidity, and good for lens and flow-visualization models.
