TPU filament is a flexible 3D printing material used for parts that need to bend, compress, grip or absorb impact. It is commonly used for protective cases, anti-slip feet, bumpers, flexible joints, model tyres, seals, grips and other functional prints that would be unsuitable for rigid PLA or PETG.

TPU can produce extremely useful parts, but it behaves differently from ordinary rigid filament. Because the filament itself can flex and compress, it generally needs a controlled feeding path, slower print speeds and careful retraction settings. It is also sensitive to moisture, which can cause stringing, bubbling and inconsistent extrusion.

ZIRO TPU 95A recommended starting settings

The following settings are the manufacturer’s recommended starting ranges for ZIRO TPU 95A. They should be treated as starting points rather than guaranteed settings for every printer and model.

ZIRO officially recommends a nozzle temperature of 200–230°C, a heated-bed temperature of 50–60°C and a print speed of 30–50 mm/s for its TPU 95A filament.

The ideal result within those ranges will still depend on:

• Printer and extruder design
• Nozzle diameter
• Layer height
• Model geometry
• Selected acceleration
• Cooling
• Retraction
• Required surface finish
• Condition of the filament

Start with the printer manufacturer’s TPU profile where one is available, then adjust one setting at a time.

What is TPU filament?

TPU stands for thermoplastic polyurethane.

It is a type of thermoplastic elastomer: a material that can combine rubber-like flexibility with the heat-processing behaviour required for filament extrusion. It softens when heated inside the hotend and becomes flexible again after cooling.

Depending on the exact formulation, TPU can provide:

• Flexibility
• Elastic recovery
• Impact absorption
• Abrasion resistance
• Resistance to repeated bending
• Grip and friction
• Tear resistance
• A softer surface than rigid filament

TPU formulations are not all identical. Two products with the same Shore hardness can still differ in extrusion behaviour, elasticity, surface texture, flow rate and chemical resistance.

Always use the specifications supplied for the exact filament rather than applying settings from an unrelated TPU product.

---

Is TPU the same as rubber?

TPU can feel and behave like rubber in many applications, but it is not natural rubber or cured silicone.

The major difference is that TPU is a thermoplastic. It can be softened with heat, extruded through a nozzle and formed into a new shape.

Cured silicone and many conventional rubbers cannot simply be melted and printed through a standard filament printer.

TPU is therefore useful when you want rubber-like flexibility from a material that can be printed using compatible FDM or FFF equipment.

---

What does TPU 95A mean?

The 95A rating refers to Shore hardness.

Shore hardness measures how resistant a material is to indentation. Flexible polymers are commonly measured using the Shore A scale.

Within the same scale:

• A lower number normally indicates a softer material.
• A higher number normally indicates a firmer material.
• 85A TPU is generally softer than 95A TPU.
• 95A TPU is normally easier to feed than very soft flexible filament.

Shore hardness does not completely describe how flexible a finished print will feel.

The flexibility of the printed part is also strongly affected by:

• Wall count
• Wall thickness
• Infill percentage
• Infill pattern
• Top and bottom layers
• Part thickness
• Model shape
• Print orientation

In addition, the flexibility of a finished TPU part depends on the model and slicer settings as well as the filament’s nominal Shore hardness. 

---

How flexible is 95A TPU?

TPU 95A is flexible, but it is not extremely soft.

A thin phone case or hinge printed in 95A TPU may bend easily. A thick block printed from the same material may feel relatively firm.

This is because a model’s structure controls how much material must deform under force.

To make a TPU print more flexible

Try:

• Fewer walls
• Thinner sections
• Lower infill
• Fewer top and bottom layers
• Flexible lattice structures
• Designed gaps or hinges
• A geometry that bends in the intended direction

To make a TPU print firmer

Try:

• More walls
• Thicker sections
• Higher infill
• Additional top and bottom layers
• Internal ribs
• Shorter flexible sections

Changing the wall count often has a greater effect than making a small change to infill percentage.

For functional parts, print a small test section before printing the complete model.

---

What is TPU filament used for?

TPU is best suited to parts where controlled movement, grip or impact absorption is useful.

Common TPU applications include:

• Protective phone and equipment cases
• Flexible bumpers
• Anti-slip feet
• Vibration-damping pads
• Grips and handles
• Cable strain relief
• Flexible hinges
• Protective caps
• Wearable accessories
• Model tyres and wheels
• Flexible couplings
• Washers and spacers
• Robotics components
• Seals and gaskets for non-critical applications
• Flexible prototypes
• Custom protective components

A printed TPU part should not automatically be treated as a certified seal, pressure component or safety-critical replacement part. Its suitability depends on the design, print orientation, material formulation, operating environment and required safety margin.

---

Advantages of TPU filament

Flexible and resilient

TPU can deform under load and return towards its original shape when the force is removed.

Good impact absorption

Its flexible structure makes it useful for bumpers, protective corners and components designed to cushion impacts.

Resistant to repeated bending

A properly designed TPU part can be better suited to repeated flexing than a brittle rigid material.

Useful surface grip

TPU often provides more grip than PLA or PETG, making it useful for feet, handles and contact surfaces.

Strong layer bonding

TPU can produce excellent interlayer adhesion when it is printed dry and at an appropriate temperature.

Relatively low warping

Conventional TPU generally presents less warping risk than materials such as ABS or ASA and usually does not require a heated chamber.

---

Disadvantages of TPU filament

Slower printing

Conventional TPU normally needs to be printed more slowly than PLA because excessive feed pressure can compress or buckle the filament.

More difficult filament feeding

Long tubes, sharp bends and gaps around the extruder gears can make flexible filament harder to feed.

Moisture sensitivity

TPU can absorb moisture from the air, affecting extrusion and surface quality.

Stringing

Flexible filament can be more difficult to tune for travel moves and retraction.

Difficult support removal

Supports printed from TPU may bond strongly to the model and can be difficult to remove cleanly.

Less dimensional rigidity

Because the material can flex, finished dimensions may be more difficult to measure and control than with rigid PLA.

---

Is TPU difficult to print?

TPU is more demanding than PLA, but 95A TPU is printable on many modern desktop printers.

The four main requirements are:

1. A controlled filament path
2. Dry filament
3. A moderate extrusion rate
4. Appropriate nozzle temperature

Direct-drive printers generally make TPU easier because the extruder is positioned close to the hotend.

Bowden printers can sometimes print 95A TPU, but they may require slower speeds and more careful tuning.

---

Direct-drive versus Bowden printers for TPU

Direct-drive extruders

A direct-drive extruder places the filament drive gears close to the hotend.

This provides:

• A shorter feeding path
• Less filament compression
• Fewer opportunities for buckling
• More responsive extrusion
• Easier retraction tuning

Direct drive is normally the preferred configuration for flexible filament.

Bowden extruders

A Bowden printer pushes filament through a longer tube between the extruder and hotend.

TPU can compress inside the tube, which can delay extrusion and make retraction less predictable.

For better Bowden TPU results:

• Use a smooth, low-friction tube.
• Minimise gaps around the drive gears.
• Keep the filament path as straight as practical.
• Reduce print speed.
• Avoid excessive retraction.
• Ensure the spool rotates freely.
• Start with firmer 95A TPU rather than very soft TPU.

Some Bowden printers will print TPU 95A successfully, while others may not have a sufficiently constrained feeding system.

---

Best nozzle temperature for ZIRO TPU 95A

ZIRO recommends:

200–230°C

A practical approach is to begin near the middle of that range and perform a small test print.

Consider increasing the temperature slightly when you see:

• Weak layer bonding
• Intermittent under-extrusion
• Poor flow
• Rough extrusion
• Extruder clicking caused by excessive nozzle resistance

Consider reducing it slightly when you see:

• Heavy oozing
• Excessive stringing
• Soft details
• Overly glossy or smeared surfaces

Do not automatically choose the lowest temperature.

Printing TPU too cold can increase resistance inside the nozzle, making the flexible filament more likely to compress or buckle before reaching the melt zone.

Use the lowest temperature that still produces stable extrusion and adequate layer bonding at the selected speed.

---

Best bed temperature for ZIRO TPU 95A

ZIRO recommends:

50–60°C

TPU can adhere very strongly to some build surfaces. More adhesion is not always better.

Follow the build-plate manufacturer’s material guidance. On certain plates, a glue layer may function as a release layer rather than simply an adhesive.

Avoid forcing the print from the bed while the plate is hot.

Allow the plate to cool, then flex a removable plate gently where appropriate.

---

Best print speed for ZIRO TPU 95A

ZIRO recommends:

30–50 mm/s

Start at the lower end when:

• Using a Bowden printer
• Printing small details
• Printing the first layer
• Using a complicated filament path
• Experiencing under-extrusion
• Hearing extruder clicking
• Seeing filament buckle near the gears

Increase speed only when extrusion remains consistent.

Some specially formulated high-flow TPU products can print much faster, but those settings must not be applied automatically to conventional TPU 95A. Polymaker, for example, lists different speed ranges for its standard TPU95 and its separately formulated TPU95-HF product.

---

TPU first-layer settings

A good first layer should be connected and consistent without being excessively crushed into the plate.

Start with:

• A clean build surface
• A slow first layer
• The correct plate setting
• Moderate line compression
• Stable filament flow
• The recommended bed temperature

When the nozzle is too close:

• Extrusion becomes restricted.
• Pressure builds inside the hotend.
• The extruder may click or grind.
• TPU may buckle near the gears.
• The print may become difficult to remove.

When the nozzle is too far away:

• Individual lines may not join.
• Corners may lift.
• The model may move during printing.

---

Cooling fan settings for TPU

There is no single fan percentage that is correct for every TPU formulation and model.

Cooling can improve:

• Overhangs
• Bridges
• Small details
• Layer definition

Too much cooling may reduce layer bonding.

Start with the tested TPU profile supplied for your printer or slicer, then inspect:

• Overhang quality
• Bridge sagging
• Layer adhesion
• Surface texture

For very small objects, make sure each layer has enough time to cool before the nozzle returns.

---

TPU retraction settings

TPU can string, but aggressive retraction is not always the solution.

Because the filament is elastic, excessive retraction can:

• Stretch the filament
• Create unstable nozzle pressure
• Increase buckling
• Cause inconsistent extrusion
• Contribute to jams

Before increasing retraction:

1. Confirm the filament is dry.
2. Confirm the nozzle temperature is not unnecessarily high.
3. Reduce avoidable travel moves.
4. Use the printer’s tested TPU profile.
5. Make small retraction adjustments.
6. Test after each change.

Retraction values are highly printer-dependent. For example, Polymaker publishes different retraction starting points for direct-drive and indirect-drive systems, illustrating why one universal TPU retraction setting is inappropriate.

---

Can TPU print bridges and overhangs?

TPU can print modest bridges and overhangs, but flexible extrusions can sag before cooling.

Improve unsupported sections by:

• Reducing bridge speed
• Applying suitable cooling
• Shortening unsupported spans
• Reorienting the model
• Replacing steep overhangs with chamfers
• Dividing the model into separate parts
• Testing bridge flow
• Avoiding unnecessary supports

A small test print is worthwhile when bridge quality is critical.

---

Does TPU require an enclosure?

Conventional TPU 95A usually does not require a heated enclosure.

An enclosure may stabilise room conditions or support emission control, but excessive chamber heat can soften filament before it reaches the extruder and may increase feeding problems on some printers.

Use the printer and filament manufacturer’s recommendations rather than assuming that a hotter enclosure will improve TPU printing.

---

Can ZIRO TPU 95A be used in the Bambu Lab AMS?

ZIRO TPU 95A should be fed through an approved external spool path rather than a standard Bambu Lab AMS or AMS Lite.

Bambu Lab’s filament compatibility guidance lists soft materials such as TPU 95A, 85A and similar Shore A grades among those that are not recommended for standard AMS feeding. Its AMS Lite guidance also states that 95A TPU is not suitable for AMS Lite feeding.

What about “TPU for AMS”?

Bambu Lab also offers or documents specially formulated TPU for AMS.

That is a distinct product category engineered to feed through the AMS. It should not be confused with conventional TPU 95A.

“TPU for AMS” does not mean all TPU filament is AMS compatible.

Always check:

• The exact filament product
• Shore hardness
• Printer model
• AMS model
• Current manufacturer compatibility guidance

For more material-specific Bambu information, read our Best Filament for Bambu Lab Printers.

---

How to load TPU filament

1. Check that the filament is dry.
2. Place the spool where it can rotate freely.
3. Make sure the filament is not crossed or tangled.
4. Cut the end cleanly.
5. Use the approved external-spool feeding path.
6. Minimise sharp bends and unnecessary tubing.
7. Heat the nozzle to the correct loading temperature.
8. Feed slowly.
9. Confirm smooth extrusion before starting the print.

Do not force TPU through an obstructed path.

When resistance increases, unload the filament and identify the cause.

---

Does TPU absorb moisture?

Yes. TPU is hygroscopic, meaning it can absorb moisture from its surrounding environment.

Possible signs of moisture-affected TPU include:

• Popping or crackling sounds
• Bubbles at the nozzle
• Excessive stringing
• Rough surfaces
• Tiny holes
• Inconsistent extrusion
• Uneven flow
• Reduced print quality

Moisture may be present even when the spool feels dry.

Store TPU sealed with desiccant whenever it is not being used.

For a complete explanation of filament moisture, visit our How to Dry 3D Printer Filament guide.

---

How to dry TPU filament

Drying requirements vary between TPU formulations.

There is no drying temperature or duration that should be applied blindly to every spool.

For example, Polymaker lists 70°C for eight hours for moisture-affected PolyFlex TPU95, while other TPU products may specify different temperatures or durations. This is why the instructions for the exact manufacturer and product must take priority.

For ZIRO TPU:

• Check the spool, packaging and current ZIRO instructions first.
• Use a temperature-controlled filament dryer.
• Verify that the dryer maintains a stable temperature.
• Avoid temperatures that could soften the filament or deform the spool.
• Store the spool immediately after drying.
• Replace or regenerate saturated desiccant.

Avoid using an unverified domestic oven. Household ovens may cycle or overshoot at lower settings, potentially deforming the spool or filament.

---

How to store TPU correctly

For reliable results:

• Keep TPU in a sealed bag or dry box.
• Include active desiccant.
• Keep it away from humid air.
• Do not leave it exposed on the printer unnecessarily.
• Replace or regenerate saturated desiccant.
• Keep dust away from the filament.
• Avoid tightly bending or kinking the filament.

Vacuum packaging helps protect a new spool before opening, but the filament can begin absorbing moisture after the package is opened.

---

Best infill for TPU

There is no universally best TPU infill.

The correct pattern depends on how the part needs to deform.

Gyroid

Gyroid can provide relatively even support in multiple directions and is a useful starting point for compressible objects.

Cubic patterns

Cubic-style patterns offer multidirectional internal support and become firmer as density increases.

Grid

Grid is simple and strong but can create a firmer internal structure because of intersecting lines.

Low-density infill

Lower infill generally allows more compression but may provide less support beneath top surfaces.

High-density infill

Higher infill reduces compression and can make the part feel significantly firmer.

Do not choose flexibility based on infill alone. Wall count, wall thickness and model geometry can have an even greater effect.

---

Designing models for TPU

TPU works best when the model has been designed for flexible material.

Consider:

• The direction in which the part should bend
• Wall thickness
• Required clearances
• Compression distance
• Internal gaps
• Sharp corners
• Print orientation
• Repeated flexing
• Contact with heat, oils or chemicals
• Required dimensional accuracy

Use rounded transitions rather than sharp internal corners where repeated bending is expected.

Print orientation also matters because an FDM part may behave differently along the layer lines than across them.

---

Printing TPU supports

Supports printed from TPU may bond strongly to the model and can be difficult to remove.

Before adding extensive support:

• Rotate the model.
• Split it into separate pieces.
• Replace severe overhangs with chamfers.
• Use bridging where practical.
• Move support contact to less visible areas.
• Carefully adjust support separation.
• Test a small section.

Do not assume that ordinary PLA support settings will work well with TPU.

---

TPU troubleshooting

TPU is not feeding

Possible causes include:

• Excessive spool resistance
• Sharp bends in the filament path
• Printing too quickly
• Nozzle temperature too low
• A partial blockage
• Excessive extruder tension
• Filament buckling
• Gaps after the drive gears

Try:

1. Unload the filament.
2. Inspect it for flattening or twisting.
3. Make sure the spool turns freely.
4. Check the complete feeding path.
5. Confirm that the nozzle is clear.
6. Reduce print speed.
7. Increase temperature slightly within ZIRO’s range.
8. Avoid excessive gear pressure.
9. Feed from a shorter external path.

---

Extruder clicking while printing TPU

Extruder clicking usually means the filament cannot move at the requested rate.

Potential causes include:

• Print speed too high
• Volumetric flow too high
• Nozzle temperature too low
• Nozzle too close to the bed
• Partial nozzle blockage
• Excessive spool drag
• Filament buckling near the gears

Do not automatically increase extruder tension. Additional pressure can flatten flexible filament and make feeding worse.

---

TPU buckles near the extruder

Buckling occurs when the filament bends sideways rather than moving into the hotend.

Try:

• Lowering print speed
• Increasing nozzle temperature slightly within the approved range
• Reducing gaps in the filament path
• Using direct drive where possible
• Reducing spool resistance
• Checking extruder tension
• Reducing aggressive retraction
• Using a larger nozzle where suitable

---

TPU stringing

Before changing retraction, check whether the filament is dry.

Moisture and excessive nozzle temperature can both contribute to stringing.

Try:

1. Drying the filament according to appropriate manufacturer guidance.
2. Reducing nozzle temperature in small increments.
3. Tuning retraction conservatively.
4. Reducing travel over open areas.
5. Using wipe or travel-avoidance features where available.
6. Printing a small retraction test.

A small amount of fine stringing may still occur, but severe stringing normally indicates moisture or tuning problems.

---

Rough, bubbly or pitted TPU surfaces

This commonly indicates moisture.

Listen for popping and examine the extruded filament for bubbles.

Dry the spool before making large changes to flow or retraction.

Other possible causes include:

• Excessive nozzle temperature
• Inconsistent feeding
• Partial nozzle blockage
• Excessive speed
• Contaminated filament

---

TPU under-extrusion

Possible causes include:

• Print speed too high
• Temperature too low
• Wet filament
• Nozzle blockage
• Filament slipping
• Excessive spool drag
• Incorrect flow calibration
• Excessive extruder tension

Reduce speed and inspect the feeding path before making a large increase to the flow setting.

Increasing flow cannot correct filament that is buckling before it reaches the nozzle.

---

Weak TPU layer adhesion

Try:

• Raising nozzle temperature slightly
• Reducing excessive cooling
• Reducing print speed
• Drying the filament
• Checking flow calibration
• Increasing wall thickness
• Changing model orientation

A print that looks acceptable may still be unsuitable for a demanding functional application. Test functional parts under realistic conditions.

---

TPU sticks too strongly to the build plate

Allow the plate to cool before removing the model.

Depending on the build surface:

• Flex the removable plate gently.
• Use an appropriate release layer next time.
• Reduce excessive first-layer compression.
• Confirm that the bed is not hotter than necessary.
• Follow the plate manufacturer’s instructions.

Avoid sharp removal tools that could damage the surface or cause injury.

---

TPU corners are lifting

Possible causes include:

• Contaminated build plate
• First layer too high
• First layer too fast
• Excessive cooling
• Unsuitable bed temperature
• Small model contact area

Clean the build surface using the approved method, slow the first layer and consider adding a brim.

---

TPU dimensions are inaccurate

Flexible parts can deform while being printed and measured.

Check:

• Flow calibration
• Wall count
• Print speed
• First-layer expansion
• Hole compensation
• Print orientation
• Measurement pressure
• Whether the part bends under callipers

Print a small functional-fit sample using the same settings and orientation as the finished model.

---

Is TPU waterproof?

TPU material may resist water, but an FDM-printed component should not automatically be considered waterproof.

Printed objects can contain:

• Gaps between extrusion lines
• Layer-boundary defects
• Seams
• Pinholes
• Incomplete walls

A print may be water resistant without being reliably watertight.

Test the complete printed part under its actual intended conditions.

---

Is TPU food safe?

Do not assume that TPU filament or a TPU print is food safe.

Food-contact suitability depends on:

• Exact polymer formulation
• Pigments
• Additives
• Manufacturer certification
• Printer and nozzle contamination
• Printed surface porosity
• Cleaning method
• Contact duration
• Food temperature
• Intended use

Is TPU safe to print indoors?

Material-extrusion 3D printers can release particles and volatile compounds. Emissions depend on the material, printer, colour, temperature and operating conditions.

NIOSH recommends engineering controls such as ventilation, enclosed ventilated systems and suitable filtration to reduce unnecessary exposure.

Use sensible controls:

• Print in a well-ventilated area.
• Avoid placing printers in sleeping spaces.
• Avoid remaining unnecessarily close to operating printers.
• Consider appropriate source extraction or filtration.
• Follow the filament safety data sheet.
• Avoid overheating filament.
• Use stronger controls in schools, workplaces and print farms.

---

TPU versus PLA

Choose PLA when you need a rigid, detailed and easy-to-print model.

Choose TPU when bending, compression, grip or impact absorption is part of the design.

For a detailed explanation of PLA, read our Ultimate PLA Filament Guide.

---

TPU versus PETG

Choose PETG when the part should remain rigid while offering better toughness and durability than ordinary PLA.

Choose TPU when the part must intentionally deform.

Learn more about rigid functional filament in our Ultimate PETG Filament Guide.

---

TPU versus TPE

TPE means thermoplastic elastomer, which is a broad family of flexible thermoplastic materials.

TPU is one type of thermoplastic elastomer based on polyurethane chemistry.

In the 3D printing market, the term TPE is sometimes used for very soft flexible filament, but product naming is not completely standardised.

Always compare:

• Polymer type
• Shore hardness
• Recommended print settings
• Printer compatibility
• Technical data

Do not select a flexible filament based only on the label TPU or TPE.

---

Frequently asked questions about TPU filament

Is TPU suitable for beginners?

TPU 95A can be suitable for someone who is already comfortable printing PLA and using slicer profiles.

A modern direct-drive printer with a tested TPU profile makes the process significantly easier.

---

Can every 3D printer print TPU?

No.

The printer must be able to feed flexible filament without allowing it to buckle or escape from the filament path.

Many direct-drive printers can print 95A TPU successfully, while some Bowden printers and automatic feeding systems may struggle.

---

Does TPU require a hardened nozzle?

Ordinary unfilled TPU does not normally require a hardened nozzle simply because it is TPU.

Abrasive TPU composites containing fibres or hard particles may require abrasion-resistant components.

Check the exact filament specifications.

---

What nozzle size is best for TPU?

A 0.4 mm nozzle is a practical starting point for TPU 95A.

A larger nozzle can reduce extrusion resistance and may improve reliability, although it also changes:

• Detail
• Wall thickness
• Layer width
• Required flow
• Print time

Very small nozzles create more resistance and can be harder to use with flexible filament.

---

Can TPU be used for phone cases?

Yes. Protective cases are a common TPU application.

The model must be designed with the correct clearances, wall thickness and flexibility for the specific device.

---

Can TPU be used for model tyres?

Yes. TPU is commonly used for model tyres and flexible wheels.

Tyre flexibility depends on:

• Shore hardness
• Wall thickness
• Infill
• Tread design
• Internal structure

---

Can TPU be used outdoors?

Outdoor performance depends on the exact TPU formulation, colour, additives and environmental conditions.

Do not assume that every TPU grade has the same resistance to ultraviolet light, heat, water and temperature cycling.

---

Can TPU be used for seals and gaskets?

TPU can be used for experimental or low-risk gaskets and seals.

It should not automatically replace a certified component in:

• Pressurised systems
• Medical equipment
• Safety systems
• Critical plumbing
• Regulated machinery

---

Why does my TPU print feel too hard?

The part may have:

• Too many walls
• High infill
• Too many top and bottom layers
• Sections that are too thick

Reduce the amount of structural material or redesign the model to flex.

---

Why does my TPU print feel too soft?

Increase:

• Wall count
• Wall thickness
• Infill
• Top and bottom layers
• Internal supports
• Part thickness

---

TPU printing checklist

Before starting a TPU print:

• Confirm the filament type and Shore hardness.
• Check the manufacturer’s temperature range.
• Make sure the filament is dry.
• Use a short, low-resistance feeding path.
• Avoid feeding conventional 95A TPU through the standard AMS.
• Make sure the spool rotates freely.
• Begin with a conservative print speed.
• Use a slow and properly calibrated first layer.
• Keep retraction conservative.
• Print a small test before committing to a long job.
• Test functional components under realistic conditions.
