⚙️ Material Properties
Shore Hardness: 85A
– Very flexible and elastic
– Can be bent, twisted, or compressed without breaking
Excellent impact resistance
Abrasion-resistant
Good chemical resistance (oils, greases, some solvents)
Elastic recovery: Bounces back to original shape after deformation
🔧 Printability
Moderate printing difficulty
– Softer TPUs like 85A are harder to print than rigid materials (e.g., PLA or PETG)
– Works best with direct-drive extruders (like those in Bambu Lab’s A1 and X1 series)
Lower print speeds recommended to prevent jamming or under-extrusion
Requires tuned retraction settings to avoid stringing
📦 Recommended Print Settings
Nozzle Temp: 220–240°C
Bed Temp: 30–60°C
Print Speed: 20–40 mm/s (slower = better with soft TPU)
Cooling Fan: 0–30% (too much cooling can affect layer adhesion)
Retraction: Minimal or off (to prevent clogging/stringing)
