SainSmart Flex TPU Air Lightweight Foaming TPU Filament 1.75mm

Flex TPU Air is a 1.75mm lightweight TPU filament that foams as it prints. By changing print temperature and speed you set how hard or soft the part comes out, anywhere from 77A to 93A, so one spool covers everything from firm grips to cushioned insoles. It is aimed at wearables, sports gear and other parts that touch skin.

Key features

• Adjustable hardness from 77A to 93A: lower temperatures give denser, stronger parts, higher temperatures trigger foaming for lighter, softer results
• Expands up to 172% in volume, cutting part weight by up to 50% compared with standard TPU
• 1kg prints roughly the same volume as 2kg of regular TPU
• High resilience: parts spring back to shape after compression
• Matte, soft-touch finish that hides layer lines
• Available in White, Black and Gray
