Regular TPU has always been slow to print — the soft strand buckles inside the extruder if you push it too hard, so most people creep along and hope for the best. Bambu reformulated this one around a high-speed thermoplastic polyurethane that flows up to \u003cstrong\u003e12 mm³\/s\u003c\/strong\u003e, about \u003cstrong\u003ethree times faster than standard TPU 95A\u003c\/strong\u003e.

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.

If a spool has been open for more than a few days, run it at 70 °C for 8 hours before a big print, and store it sealed with fresh desiccant below 20% RH — worth taking seriously in humid Australian summers, especially up north.\u003c\/p\u003e\n\u003cp style=\"line-height:1.7;\"\u003e\u003cstrong\u003eLet the extruder do the work.\u003c\/strong\u003e Most TPU failures are feed problems, not temperature problems. Load it from the external spool holder with the shortest, straightest path you can manage, make sure the spool spins freely, and keep retraction short. If you see gaps in the walls, slow down before you reach for the temperature dial. One more thing worth knowing: flexible parts print best with a few extra walls and low infill — 3 walls and 10–15% gyroid gives you that satisfying springy feel, while high infill just makes the part stiff and wastes filament.\u003c\/p\u003e\n\n\u003cdiv style=\"background:#f7f8ff; border-left:4px solid #020873; border-radius:4px; padding:18px 22px; margin-top:24px;\"\u003e\n  \u003cp style=\"margin:0; line-height:1.7; color:#020873;\"\u003e\u003cstrong\u003eStock held in Australia · Fast dispatch · GST-inclusive pricing\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Bambu Lab","offers":[{"title":"TPU 90A","offer_id":53666082652449,"sku":null,"price":91.99,"currency_code":"AUD","in_stock":false},{"title":"TPU 85A","offer_id":53666082685217,"sku":null,"price":68.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1000\/5046\/9153\/files\/silver_2.png?v=1790952070"}],"url":"https:\/\/ne3dprinting.myshopify.com\/collections\/tpu.oembed","provider":"NE3D Printing","version":"1.0","type":"link"}
