Flexible, Rubber-Like Parts

TPU (thermoplastic polyurethane) is a flexible, rubber-like material that bends, stretches and springs back. It brings elasticity and shock absorption to parts that rigid plastics simply cannot deliver.

At Solidium3D we print TPU for seals, gaskets, grips, bumpers and flexible fittings. Upload your STL for an instant quote and tell us the flexibility you need, we will match the right shore hardness.

Why Choose TPU

Elasticity, grip and durability for parts that need to flex.

Flexible & Elastic

Bends and stretches, then returns to shape.

Shock Absorbing

Cushions impacts and dampens vibration.

Abrasion Resistant

Tough wearing surface for grips and pads.

Good Grip

Soft-touch, high-friction surfaces.

Chemical Resistant

Handles oils and many chemicals.

Durable

Survives repeated bending and compression.

TPU for Seals, Grips & Gaskets

TPU is ideal for seals, gaskets, grips, bumpers, straps and protective covers, parts that must flex, cushion or grip in service.

We can print a range of flexibilities (shore hardness) to match your application, from firm-but-flexible to soft and rubbery. Tell us how the part is used and we will recommend the right feel.

What TPU Is Best For

Seals & Gaskets

Flexible sealing parts for enclosures and fittings.

Grips & Handles

Soft-touch, high-friction surfaces.

Bumpers & Pads

Shock-absorbing protective components.

Straps & Bands

Stretchable, durable flexible parts.

Phone/Device Cases

Protective, flexible enclosures.

Vibration Dampers

Mounts that isolate vibration and noise.

How It Works

From CAD file to flexible TPU parts in four simple steps.

1Upload Your Files

Upload STL, OBJ, STEP or STP files for an instant, geometry-based TPU price.

2Choose Flexibility

Select TPU, tell us the feel you want, and set quantity with live pricing.

3Tuned Flexible Printing

We print TPU slowly with settings that keep flexible walls watertight and strong.

4QC & Dispatch

Every part is inspected, packed and dispatched Australia-wide within 2 to 5 business days.

Design Tips for Flexible Parts

Flexible parts behave differently, and small design decisions change the feel dramatically. Wall count controls stiffness: two perimeter walls give a squashy grip, four walls a firm bumper, even in the same TPU. Tell us the feel you want and we will tune it.

For seals and gaskets, design 10 to 15 percent compression into the groove depth: TPU seals by squashing, and that preload keeps joints tight through vibration. Avoid knife-edge features below 1 mm; flexible materials tear from thin notches.

Straps, bands and hinges last longest when the bending region has uniform thickness and rounded roots. If a part stretches in service, keep elongation under about 20 percent of TPU's limit for effectively infinite fatigue life.

Finishing & Post-Processing

Flexible parts arrive ready to work, with options where precision matters.

Support Removal

Gentle removal that leaves flexible surfaces unmarked.

Hole Sizing

Punch-finished or drilled holes for fastener pass-throughs.

Feel Tuning

Wall and infill adjustments to hit your target softness.

Sealing Advice

Compression and groove design guidance for gaskets.

Industries That Choose TPU

Wherever parts must cushion, grip or seal, TPU delivers.

Consumer Electronics

Protective cases, bumpers and strain reliefs.

Industrial

Vibration mounts, seals and machine feet.

Medical & Wellbeing

Comfortable grips and cushioned contact parts.

Footwear & Wearables

Straps, buckles and flexible structural parts.

Automotive

Grommets, boots and vibration-damping mounts.

Robotics

Compliant grippers that handle delicate objects.

What to Send Us

3D file: STL preferred; STEP, STP and OBJ accepted.
Units & scale: millimetres, at real-world size.
Target feel: soft grip, firm bumper or something between; we tune walls to match.
Compression: for seals, tell us the groove so we design in preload.
Stretch in service: note features that flex or stretch repeatedly.
Quantity: batch pricing applies automatically in the quote tool.

TPU 3D Printing FAQs

How flexible is TPU?

TPU is rubber-like, it bends and stretches then rebounds. We can print different shore hardnesses to tune how soft or firm the part feels.

Is TPU durable?

Yes. TPU is abrasion-resistant and handles repeated bending and compression, making it ideal for grips, seals and bumpers.

Can you print soft or firm TPU?

We offer a range of flexibilities. Tell us the application and we will recommend the right grade for the feel and performance you need.

Is TPU good for seals and gaskets?

TPU is a strong choice for flexible seals and gaskets. For a fully airtight or watertight seal, we will advise on design and finishing.

What does shore hardness actually mean?

It is a squeeze test: 95A feels like a skateboard wheel, softer grades like a firm rubber band. Most functional parts print beautifully at 95A; ask if you need softer.

Will TPU parts tear?

TPU is remarkably tear-resistant if features stay above about 1 mm thick with rounded roots. Sharp internal notches are the only real enemy; we check for them before printing.

Does TPU degrade with age or sunlight?

TPU handles ageing, oils and flexing very well. For years of direct sun exposure we may suggest design tweaks or a UV-stable colour choice.

How much does TPU printing cost?

Flexible printing runs slower than rigid materials, so TPU sits modestly above PETG in price. Upload your STL for an exact instant quote.
