Application notes, material updates, and technical insights from our engineering team.
How nozzle size affects flexible filament printing, pressure, detail and reliability.
Direct drive vs Bowden feeder design for TPU: extrusion stability, retraction and part quality.
Flexible filament buckling is usually a feed-path issue.
How to store TPU filament after opening the spool to prevent moisture and deformation.
Does TPU filament need drying before printing? Symptoms, temperature, time and verification.
TPU stringing is usually driven by moisture, temperature, travel path and retraction. Dry the material first, then tune temperature and path before touching retraction.
Find a stable TPU printing speed by testing extrusion stability first, then balancing surface and layer bonding within that limit.
Flexible filament tangles or jams because of feed-path length, feeder tension, retraction, spool tension and moisture. Check mechanics before software.
TPU 95A suits flexible but structured parts: guards, covers, clips, grips, seals and light wear components.
TPU 65A is very soft, 85A balances softness and support, and 95A is semi-rigid. Choose by required deflection and load.
Filament selection follows application: temperature, load, flexibility, weather exposure, precision and printer capability, in that order.
Match the material to the part function. PLA, PETG and TPU are complementary, not interchangeable.
