At Shore 90A it bends, stretches and bounces back like a firm rubber, yet it is stiff enough to feed reliably through a direct-drive extruder — which means far fewer of the buckling and under-extrusion headaches that put people off softer 85A material. Stretch it and it will go roughly six-and-a-half times its own length before it breaks, so parts absorb impact and shrug off scuffing instead of cracking.\u003c\/p\u003e\n\u003cp style=\"line-height:1.7;\"\u003eIt is the filament to reach for when a part needs to grip, cushion, seal or survive being dropped: phone and tool cases, drone and RC bumpers, gaskets and sealing rings, vibration-damping feet for machines and speakers, watch and camera straps, wheels and tyres for RC cars, grippy jig inserts, prosthetic and orthotic padding, and protective sleeves for workshop gear. Schools and makerspaces like it because it is genuinely hard to break a finished print. If you want something softer and squishier, step down to TPU 85A; if you want to run flexible material through an AMS, you need Bambu's dedicated TPU for AMS instead.\u003c\/p\u003e\n\n\u003chr style=\"border:none; border-top:2px solid #FCD361; margin:24px 0;\"\u003e\n\n\u003ch3 style=\"font-family:Poppins, sans-serif; color:#020873; margin-bottom:14px;\"\u003eWhy makers choose TPU 90A\u003c\/h3\u003e\n\u003cp style=\"line-height:2.6;\"\u003e\n  \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003eShore 90A hardness\u003c\/span\u003e\n  \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003e650% elongation at break\u003c\/span\u003e\n  \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003eHigh abrasion \u0026amp; tear resistance\u003c\/span\u003e\n  \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003e±0.03 mm diameter tolerance\u003c\/span\u003e\n  \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003eEasier to feed than 85A\u003c\/span\u003e\n  \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003eRFID-tagged for Bambu printers\u003c\/span\u003e\n  \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003e8 colours\u003c\/span\u003e\n  \u003cspan style=\"background:#FEFFF0; border:1px solid #2B4CB9; border-radius:20px; padding:6px 16px; font-size:0.9em;\"\u003eLow bed temp — minimal warping\u003c\/span\u003e\n\u003c\/p\u003e\n\n\u003chr style=\"border:none; border-top:2px solid #FCD361; margin:24px 0;\"\u003e\n\n\u003ch3 style=\"font-family:Poppins, sans-serif; color:#020873; margin-bottom:10px;\"\u003ePrint settings\u003c\/h3\u003e\n\u003cp style=\"line-height:1.7;\"\u003eBambu Lab printers load a tuned TPU 90A profile automatically when the spool's RFID tag is read, so for most users the presets are the right starting point.

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\/products\/bambu-lab-tpu-90a","provider":"NE3D Printing","version":"1.0","type":"link"}
