Soft, bendy filament is the hardest thing you can ask a 3D printer to swallow. Squishy TPU likes to buckle, kink, and jam in the long tube that feeds most cheap machines. The fix is a direct-drive extruder — a motor mounted right at the nozzle that pushes the filament a short, straight path instead of a long, winding one. Every printer below has that, so flexible prints actually finish instead of clogging halfway through.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You will learn what a direct-drive extruder really does, why build volume and nozzle temperature matter for TPU, and which machines handle flexible filament without a fight. Here is how to pick among the best 3D printer for flexible filament choices.
Our Picks at a Glance
How To Choose The Best 3D Printer For Flexible Filament
Flexible filament is where a lot of printers quietly give up. The material is soft, so it bends instead of pushing straight through, and any slack in the feed path turns into a tangle or a clog. The machine you pick should be built around that reality, not around speed figures alone.
The extruder is the whole game
A direct-drive extruder puts the feed motor inches from the hot nozzle. That short, direct path keeps soft TPU moving straight so it does not balloon out sideways. A Bowden setup, which pushes filament through a long tube, is the wrong tool for flexibles — the extra length is exactly where soft filament folds on itself.
Temperature range widens your material menu
TPU prints comfortably at lower heat, but if you also want to run engineering-grade plastics alongside it, you need a hotter nozzle. The FLASHFORGE AD5X reaches a 300°C nozzle temperature, which opens up stiffer materials beyond basic TPU. Match the top temperature to the filaments you actually plan to feed it.
Build volume decides what you can finish in one piece
Soft parts like phone cases and grippy feet are small, so volume is rarely the limit for pure TPU. Once you start mixing rigid and soft sections in one print, or printing wearable items, a larger bed pays off. Check the printed build size rather than the outer cabinet, since those numbers differ.
Multi-toolhead versus single-nozzle
If you want multi-color soft parts, the two approaches behave very differently. A single nozzle that swaps filament purges between every color change, and flexibles are the worst offenders for waste. Independent toolheads each hold their own filament, which cuts that waste sharply — useful when the material you are throwing away is TPU.

In‑Depth Reviews
1. Bambu Lab P1S 3D Printer, Ready-to-Use FDM 3D Printer
Our pick — over 4★ from 350+ verified ratings; the strongest balance of quality and price.
The enclosed all-rounder that prints TPU and ABS in the same machine without drama
The P1S is the machine most people should look at first, because it does not force you to choose between soft and stiff filament. Its spec list includes TPU as an ideal material alongside PLA and PETG, and the fully enclosed body keeps the heat steady, which matters for advanced filaments. The 500mm/s speed keeps build times down while the auto bed leveling handles the setup routine for you.
Speed is where this one leaves the cheapest option in the dust. The P1S accelerates at 20000 mm/s², and the Creality Ender 3 V3 SE bundle manages 2500mm/s² — an 8.0x gap that shows up as far less waiting per part. The bed measures a generous 260x260x260mm, and buyers report a first print that sticks to the plate without glue, which is exactly what you want when you are laying down a soft first layer.
The honest catch is flexibles themselves. Owners note the P1S runs TPU best on slower, dialed-in settings and that it can struggle with the softest spools, though clearing a clog takes only 5-10 minutes when it happens. The 38.9-pound frame is also the heaviest here against the 28.3-pound Creality SPARKX i7, so plan a sturdy shelf. Treat TPU as a material to learn on this machine rather than an easy default.
Where it pulls ahead
- Enclosed chamber keeps advanced filaments stable and cuts noise
- Auto bed leveling and filament detection remove the guesswork
- 20000 mm/s² acceleration finishes parts far faster than budget rivals
- 15-minute setup gets you printing the same afternoon
What to weigh first
- Softest TPU needs slower speeds and careful tuning
- Heaviest machine in this round-up at 38.9 pounds
- The multi-color AMS that open up 16 colors is a separate purchase
Buy it if: you want one enclosed printer that runs rigid and flexible filament and you value a fast, level-every-time workflow.
Think twice if: you plan to burn through ultra-soft TPU all day and want a machine that shrugs it off — this one rewards patience.
2. Creality Ender 3 V3 SE 3D Printer Bundle with PLA Filament 4 Packs
A starter kit that arrives with filament in the box and a direct-drive heart
For a first printer, the bundle matters as much as the machine. This Ender 3 V3 SE ships with four rolls of PLA in black, white, red, and blue, so you can start printing the day it lands. The extruder is the real story for flexible work: a full-metal dual-gear Sprite direct-drive unit that the maker says feeds PLA, TPU, and PETG smoothly without slipping.
Setup stays simple by design. Auto leveling comes from a CR Touch sensor, and a strain sensor handles the z-offset for you, so you are not turning knobs and sliding paper. Owners mention: “Have been using it for 6 weeks and it’s been working nonstop no issues.” That kind of steady everyday use is what this machine is built for.
The ceiling here is speed and scale. It tops out at 250mm/s, and the Bambu Lab P1S above runs to 500mm/s — half the pace when you are queuing up large parts. The dual Z-axis lead screws and two 8mm steel Y-axis shafts keep small TPU prints accurate, but this is a learning machine rather than a production workhorse. If soft, small parts are your focus, the slower pace will not bother you.
Beginner-first build: The bundle-and-level pairing lowers the barrier — you get filament, auto leveling, and a direct-drive extruder without learning slicer science first.
Where it taps out: Speed is the limit, so batch jobs and tall prints take a back seat to the faster CoreXY machines on this list.
Start here if: it is your first printer and you want a direct-drive machine plus starter filament in one box.
Step up if: you already know you need speed and build size — the enclosed CoreXY options serve that better.
3. Creality SPARKX i7 Autofill Combo 3D Printer
Runs overnight without you hovering, thanks to auto spool switching and a watchful camera
The SPARKX i7 solves the one thing that ruins long flexible prints: running out of filament at hour nine. When the active spool empties, it switches to a backup automatically, so a big TPU job keeps going instead of stopping dead. An AI camera watches the print, detects failures, and records time-lapses, all reachable through your phone.
It is a genuine high-speed machine, not just a starter. The direct-drive extruder feeds TPU, PETG, and PLA, and it hits 500mm/s — twice the 250mm/s of the Ender 3 V3 SE bundle. The 260x260x255mm build volume handles cosplay props and functional parts, and the flexible PEI plate lets finished models pop off without a scraper.
Quiet operation is a real bonus for a home setup, with noise levels as low as 45dB, roughly the hum of a quiet conversation. The reliability picture is the mixed part — most customers note flawless runs, and an occasional unit has thrown a firmware or support-snag.
Best idea on the spec sheet: autofill plus AI failure detection means an overnight flexible print is realistic, not a gamble.
Do your homework: support experiences vary, so buy from a seller with a clear return path.
Reach for this if: you run long, unattended prints and want a lighter, quieter machine that feeds TPU directly.
Look elsewhere if: you want a proven multi-year support reputation — a couple of owners hit warranty friction with this one.
4. TEQStone M1S Mini 3D Printer for Kids & Beginners
The desk-friendly mini that lets a kid print squeezable toys without learning slicer software
Most beginner printers only handle stiff plastic. The TEQStone M1S is different because its direct-drive extruder feeds both PLA and flexible TPU, so your household can print squeezable toys, phone cases, and wearable items that a cheap Bowden machine cannot. At 8.8 pounds it moves easily between rooms, and the compact footprint fits on a desk.
Setup is genuinely quick — from unboxing to a first print in about 15 minutes, and you drive it from a mobile app over Wi-Fi with no slicer to learn. Auto leveling uses a 16-point system to flatten the bed automatically, backed by auto nozzle cleaning. Its 250mm/s top speed prints a standard Benchy boat model in a quoted 29 minutes.
The trade-offs are real but narrow. It natively feeds only smaller 0.5kg spools, so full-size spools need a workaround, and the build area is small by design. Soft TPU runs on this machine, but the print-speed aspect earns mixed marks from buyers. It is a family machine first and a workshop machine second.
Why families like it
- Direct-drive extruder handles flexible TPU, not just rigid PLA
- App and Wi-Fi control skip the slicer learning curve
- 16-point auto leveling plus nozzle cleaning reduce first-layer failures
- Compact, quiet, and light enough to relocate easily
Know before you buy
- Feeds only smaller 0.5kg spools natively; bigger rolls need a workaround
- Small build area limits model size
- Print speed earns mixed feedback in owner reports
Made for: households introducing kids to 3D printing and anyone who wants soft, squeezable prints without a steep setup curve.
Not the pick if: you need a large bed or full-size spool support for bigger production runs.
5. Anycubic Kobra X Multicolor 3D Printer
Built-in four-color printing with a hot nozzle that handles rigid and flexible filament at speed
Color and speed come standard here. The Kobra X arrives with four colors built in and can expand to 19 colors with additional ACE 2 Pro units. A hardened steel nozzle pushes a 300°C maximum temperature, and the machine supports mixed printing of stiff and soft filament including PLA, PETG, TPU, PVA, and ASA.
Speed is the headline number. It reaches 600mm/s and finishes a Benchy benchmark in a quoted 14 minutes, faster than the 500mm/s Bambu Lab P1S. The LeviQ 3.0 system uses 49-point calibration to level the bed, and the top-mount spool holder frees up desk space. Dual-band Wi-Fi and LAN let you monitor the job from your phone.
Where it gets bumpy is long-term reliability. Owners describe many hundreds of hours of clean PLA, PETG, and TPU printing with almost no failures, but a smaller set report trouble after a couple of months. The 260x260x260mm volume handles mixed-material parts nicely. Plan on routine maintenance to keep it running smooth.
The draw: built-in four-color printing plus a 600mm/s sprint and a hot hardened nozzle give you a lot of capability for the tier.
The caveat: reliability divides owners, so treat it as a machine that rewards regular upkeep rather than a plug-in-and-forget box.
Choose this if: you want multi-color capability from the start and fast TPU printing in one machine.
Go simpler if: you would rather trade color for a machine with fewer reports of mid-life hiccups.
6. FLASHFORGE AD5X Multi-Color 3D Printer
Widens your material menu with a 300°C nozzle and an all-metal CoreXY frame
If you want to print flexible TPU alongside stiffer engineering materials, the ceiling on nozzle temperature is what decides it. The AD5X tops out at 300°C, so it can handle filaments that softer-temperature machines cannot touch. It also supports flexible TPU directly, and the all-metal CoreXY structure keeps the frame rigid so prints stay accurate at speed.
Multi-color runs up to four colors at once, and the Intelligent Filament System detects and refills filament on its own, cutting the downtime that interrupts long jobs. Speed reaches 600mm/s with a quoted 20,000mm/s acceleration, matching the fastest machines here. The build size is a 220x220x220mm cube.
The 220mm bed is the tightest on this list, so oversized models will not fit in one piece. Reliability also divides owners cleanly — many run dozens of models without issue, while a subset hit failures within the first month. The auto spool switching is the standout: buying two for model railroading, owners ran 12kg of filament through each and leaned on same-color switching to prevent mid-print runout.
Strongest card: the 300°C nozzle plus CoreXY rigidity means one machine covers soft TPU and hot-running engineering filament.
Smallest bed here: at 220x220x220mm, plan your larger parts around the limited build volume or print in sections.
Pick this if: you need a hot nozzle for advanced materials and want automatic filament refilling for long runs.
Pass if: you need a big build plate — the 220mm cube is the smallest footprint here.
7. FLASHFORGE Creator 5 Multi-Color 3D Printer with 4 Independent Extruders
Four independent extruders make multi-color TPU prints that single-nozzle machines cannot manage
Flexible multi-color is where single-nozzle printers fall apart, and this machine sidesteps the problem entirely. It carries four fully independent direct-drive extruders, so each material runs through its own dedicated path. That setup supports simultaneous PLA, flexible TPU, and engineering-grade printing — including multi-color TPU work that trips up single-extruder systems. With no load-and-purge cycle, the maker quotes color changes up to 5 times faster.
The frame is built for speed and stability. A rigid CoreXY structure reaches 600mm/s with 30,000mm/s² acceleration and automatic flow compensation. The 256 x 256 x 256 mm build chamber fits larger models, and auto bed leveling plus AI failure detection watch the print so you are not tied to it. A 4-inch touchscreen supports 9 languages, and nozzle swaps take about 30 seconds with no disassembly.
For anyone running several machines, the group control feature lets you manage multiple units from one interface. That is aimed at farm operators and studios rather than a single hobby desk. It is a heavier investment in both desk space and setup effort, but the payoff is soft-material printing without the waste.
Built for soft multi-color
- 4 independent direct-drive extruders keep flexible filament fed without cross-contamination
- No purge cycles, so multi-color work is quoted up to 5 times faster
- 600mm/s CoreXY speed with 30,000mm/s² acceleration
- 30-second tool-free nozzle swaps and 9-language touchscreen
Weigh the commitment
- Highest-tier machine aimed at studios and multi-unit setups
- Group control adds complexity a single hobbyist may not need
- Larger 256mm build takes up more shelf space
Best for: creatives and small studios printing multi-color TPU who want to stop throwing material away on purges.
Overkill if: you print single-color functional parts — the cheaper enclosed options cover that just fine.
8. FLASHFORGE Creator 5 4-Toolhead Changer 3D Printer
Toolheads that preheat in the background so color changes take seven seconds flat
Four independent toolheads are the core idea here, and they solve two problems at once. Because each color gets its own toolhead, there is no color mixing or clogging between them, and the maker quotes up to 80% less filament waste than single-nozzle multi-color setups that purge between switches. The toolheads preheat in the background, so a change takes about 7 seconds instead of a long flush cycle.
The multi-material story runs deeper than color. You can print PLA, PETG, TPU, PETG-CF, and support materials in a single job, and by giving one toolhead entirely to support filament, the machine delivers supports that pull away cleanly for smooth surfaces. That is handy when part of a model uses flexible TPU and part needs rigid support.
The motion system keeps pace — a rigid CoreXY frame with fully automatic calibration and active vibration compensation, reaching 600mm/s. Print quality is what wins people over, with a dedicated support toolhead delivering near-flawless surface finishes. It is a serious machine, so plan for a solid, stable platform.
The breakthrough: assigning one toolhead to support filament gives you supports that remove cleanly, which matters on soft, layered TPU parts.
Give it room: a heavy 600mm/s CoreXY machine wants a sturdy bench and a little clearance around it.
Great match if: clean support removal and near-zero purge waste matter more to you than the simplest setup.
Simple wins if: you only ever print one color and one material — this machine’s strengths go unused.
9. Snapmaker U1 3D Printer, 4-Toolhead with 5s Toolchanger
Four preheated toolheads that combine rigid and flexible materials in a single print
The U1 is the machine for mixing materials most people assume need two printers. Its SnapSwap system runs four independent toolheads with filament preloaded and preheated, so it can combine rigid and flexible materials, water-soluble supports, and engineering plastics in one job. It even handles TPUs of different shore hardness in a single model, and the maker tested the toolhead locking mechanism through over 1,000,000 swaps.
Tool changes are the party piece: the automatic changer cuts change time from about 2 minutes to just 5 seconds, and by swapping toolheads instead of purging filament, it cuts waste by up to 5X. Speed sits at 500mm/s on a rigid CoreXY frame, and the 270 x 270 x 270 mm build volume is the largest in this lineup — bigger than the 256mm Creator 5 and the 260mm Bambu Lab P1S.
What stands out in owner reports is the waste savings on real jobs. One owner’s 32-hour multi-color print ran with near-zero waste, versus roughly 58 hours and 350g of purge on a single-nozzle setup. It is the priciest and heaviest option here at 59 pounds, so it wants a permanent home.
Material freedom: mixing rigid and flexible TPU in one print opens parts no single-material machine can make.
Space and weight: at 59 pounds with a 270mm build, you need a dedicated bench, not a corner of a desk.
Worth it if: you want the widest material range, the largest build volume, and the least purge waste in one machine.
Look down-market if: you print single-material parts — the enclosed mid-tier options get you there for far less.
Understanding the Specs
Direct-Drive vs Bowden Extruders
A direct-drive extruder mounts the feed motor right next to the nozzle, so filament travels a very short distance before it melts. Soft TPU needs this because a long feed path lets flexible material buckle sideways instead of pushing straight through. A Bowden extruder sends filament through a long tube to a distant nozzle — fine for rigid plastic, but the extra length is where flexibles kink and clog. That is why every printer here uses direct drive or independent toolheads.
Nozzle Temperature Range
Nozzle temperature decides which filaments you can melt and print cleanly. Softer TPU runs at lower heat, but stiffer engineering materials need more. The FLASHFORGE AD5X reaches a 300°C nozzle temperature and the Anycubic Kobra X also caps at 300°C, which lets both run a wider material menu. Match the top temperature to the filaments you actually intend to feed it, not just the ones you might try once.
Build Volume and Bed Size
Build volume is the printable cube your model must fit inside. Pure TPU parts like grippy feet and phone cases are small, so a modest bed is plenty. Once you mix rigid and soft sections in one piece, or print wearable items, the bed becomes the limit. The Snapmaker U1 offers a 270 x 270 x 270 mm volume, the largest here, while the FLASHFORGE AD5X runs a 220 x 220 x 220mm cube, the smallest.
Multi-Toolhead vs Single-Nozzle Color
Multi-color printing works two ways. A single nozzle swaps filament colors and purges in between, wasting material — costly when the material is soft TPU. Independent toolheads each carry their own filament and switch without purging, which cuts waste sharply. The FLASHFORGE Creator 5 quotes up to 80% less waste, and the Snapmaker U1 cuts waste by up to 5X by swapping toolheads instead of purging filament.

Final Thoughts: The Verdict
If you want one machine that prints both squishy TPU (a rubbery filament that bends) and stiff filament, the 3d printer for flexible filament pick for most people is the Bambu Lab P1S. Its enclosed body keeps heat steady, and its direct-drive feed (the motor sits right at the nozzle, so it pushes soft filament instead of letting it bunch up) handles both jobs. Its 20000 mm/s² acceleration (how fast the print head speeds up) finishes parts far quicker than budget rivals. Want multi-color soft parts without tossing leftover material? The Snapmaker U1 has four preheated toolheads (separate nozzles that each warm up on their own) that mix rigid and flexible TPU in a single print. And if you are buying your first machine, the Creality Ender 3 V3 SE bundle comes with filament in the box, so you can start printing the day it arrives. Whichever you choose, a direct-drive extruder is the one feature that turns flexible filament from a fight into a finished print.
