High Speed TPU 95A Filament 6-Pack

6kg at $24.40/kg | 6% Off + Free USA Shipping | Pick Any 6 Colors

Six kilograms of High Speed TPU 95A. Any 6 colors from our full TPU range. Vacuum-sealed per spool. Free shipping across the USA. At $24.40/kg — the smallest bulk TPU pack we offer — this is the lowest-commitment entry into HS TPU batch pricing: six colors, same manufacturing batch, free shipping on the full order, with no obligation to stock more than you need right now.

⚠️ Before you order: TPU requires a direct drive extruder for reliable printing at speed. On a Bowden setup (stock Ender 3, CR-10, standard Anycubic), TPU is printable but slow — 15–25mm/s maximum. On a direct drive printer (Bambu Lab, Voron, Prusa MK4, or any Bowden machine with a direct drive upgrade), this High Speed formulation prints cleanly at 40–80mm/s+. Confirm your extruder setup before ordering.

Which TPU Pack Is Right for Your Operation?

We carry three TPU bulk packs with two different formulations. Here's the full comparison:

⚠️ Note on pricing: The 10-pack costs less per kg ($19.88) because it's standard TPU formulation, not High Speed. Both are 95A Shore hardness with the same flexibility and mechanical profile — the difference is speed capability. Standard TPU tops out at ~50mm/s reliably; HS TPU sustains clean output at 80mm/s+ on direct drive setups.

What Is TPU 95A — Plain Language

TPU is rubber you can 3D print. The 95A is its hardness rating — imagine a shopping cart wheel. Firm enough to hold its shape and roll smoothly under load, but it compresses when you squeeze it and springs back the moment you let go. That's 95A: the most printable, most versatile TPU hardness for production use.

• Bends without breaking — TPU parts can be flexed, compressed, and twisted repeatedly without cracking. PLA and PETG snap under the same stress.
• Absorbs impact — the material deforms on impact, absorbs the energy, and springs back. Phone cases, bumpers, and protective covers work because of this property.
• Returns to shape — gaskets, seals, and vibration dampeners function because TPU keeps resetting after every compression cycle.
• Abrasion and chemical resistant — grips and handles that contact other surfaces outlast rigid materials significantly.

Pack Contents & Value Breakdown

Print Settings for High Speed TPU 95A

TPU settings differ from rigid filaments in two counterintuitive ways: retraction is much lower than you'd expect, and cooling fan is less aggressive. Follow these — don't apply your PLA profile to TPU.

3 Most Common TPU Problems — Fast Fixes

Extruder clicking / grinding
Back-pressure exceeds extruder grip — almost always too fast. Reduce speed 10mm/s and raise nozzle temp 5°C. If clicking persists, check for a partial clog or Bowden tube gap.

Stringing everywhere
Fix in order: (1) enable Combing mode; (2) dry filament at 50°C for 4 hours — wet TPU strings aggressively; (3) lower nozzle temp 5°C; (4) increase retraction 0.5mm. Don't jump to retraction before trying steps 1–3.

Print won't release from bed
Never pull TPU off a warm bed. Let it cool fully to room temperature — it releases on its own. Apply a thin glue stick before each production run as a release agent to prevent over-adhesion.

Design Tips for Flexible Parts

• Wall count controls stiffness — 2 walls = soft and highly flexible. 4 walls = noticeably firmer. Tune wall count per product for your target feel.
• Gyroid or honeycomb infill at 15–25% for maximum flexibility. Avoid grid infill — it creates directional stiffness that ruins parts that need to flex uniformly.
• Avoid supports wherever possible — removing supports from TPU tears surface layers. Orient parts to eliminate overhangs before adding supports.
• No rafts — TPU adhesion is strong enough without them and rafts leave rough bottom surfaces.

Storing 6 TPU Spools

• Keep sealed until the spool goes on the printer — TPU absorbs moisture faster than most filaments. Don't break the vacuum seal until you're loading the machine.
• Active desiccant for open spools — a filament dry box while printing is strongly recommended in humid climates. Open TPU degrades noticeably faster than PLA or PETG when exposed.
• One airtight bin handles all 6 spools comfortably with room for silica gel packs. Recharge at 120°C for 2 hours when saturated.
• Batch consistency: all 6 spools ship from the same manufacturing batch — matched color tone and print behavior across every spool.

Who Is This 6-Pack For?

• Direct drive printer operators trying HS TPU for the first time — 6 spools is enough to test the formulation across 6 color profiles, validate the speed and quality on your specific setup, and decide whether to scale to the 16-pack before committing larger inventory.
• Sellers with exactly 6 core flexible SKUs — if your catalog has 6 TPU colors and you go through roughly 1kg of each per production cycle, this pack aligns perfectly with your restocking rhythm at batch pricing with free shipping.
• Makers adding flexible parts to an existing PLA+ or PETG catalog — 6kg is a meaningful trial of flexible production without overstocking a material that requires different settings and hardware than your core filaments.
• Engineering and prototyping teams running regular gasket, vibration dampener, and seal projects who need a small, managed supply of HS TPU with batch consistency.
• Anyone who needs free shipping on a multi-color TPU order — individual spools ship separately; this pack ships as one order with one free shipping label regardless of how many colors you choose.
