At Shore 85A it behaves far more like rubber than plastic: squeeze a printed part and it compresses, stretch it and it will go past 700% elongation before breaking, then return to shape. That makes it the material of choice for anything that needs to grip, seal, cushion or survive being dropped — phone and drone cases, gaskets and seals, RC tyres and bumpers, watch straps and wearables, tool grips, shoe soles, vibration-damping feet and flexible living hinges. It is a rewarding material for hobbyists, makers, schools and small businesses alike; the trick is simply to slow down and feed it properly.\u003c\/p\u003e\u003cp style=\"line-height:1.75; color:#1a1a2e; margin:0 0 14px;\"\u003eSupplied on a 1.75mm, 1kg reusable spool, with two hardness options so you can match the feel your part needs.\u003c\/p\u003e\u003chr style=\"border:none; border-top:2px solid #FCD361; margin:24px 0;\"\u003e\u003ch3 style=\"font-family:Poppins,sans-serif; color:#020873; margin:0 0 14px; font-size:1.2em;\"\u003eKey features\u003c\/h3\u003e\u003cp style=\"line-height:2.4; margin:0 0 14px;\"\u003e\u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003eShore 85A — softest Bambu TPU\u003c\/span\u003e \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003e\u0026gt;700% elongation at break\u003c\/span\u003e \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003e1.75mm ±0.03mm tolerance\u003c\/span\u003e \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003eDirect-drive extruders\u003c\/span\u003e \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003e0.6mm \/ 0.8mm nozzle\u003c\/span\u003e \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003e1kg reusable spool\u003c\/span\u003e \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003eImpact \u0026amp; abrasion resistant\u003c\/span\u003e\u003c\/p\u003e\u003cp style=\"line-height:1.75; color:#1a1a2e; margin:0 0 14px;\"\u003eBambu Lab's quality control is what sets this apart from budget flexibles: a tight ±0.03mm diameter tolerance means consistent extrusion through a direct-drive hotend, where soft TPU is least forgiving.
