We have all felt that heart-stopping moment when a phone slips out of a hand and tumbles toward the pavement.
Most 3D printed cases made from PLA or PETG will shatter upon impact, transferring all that force directly to your expensive device. To truly protect your electronics, you need a material designed to act as a shock absorber.
At Siraya Tech, we have engineered the ultimate TPU phone case filament that combines superior flexibility with outstanding impact resistance.
Our material allows you to print custom, durable skins that hug your phone perfectly and bounce back from drops, all while printing fast enough to churn out a new design whenever you want a fresh look.
Protect Your Device With The Best TPU Phone Case Filament That Absorbs Shock
A phone case has one main job, which is to sacrifice itself to save your screen. Standard 95A TPU can sometimes be too stiff to absorb energy effectively, which is why we optimized our TPU phone case filament to be softer and more resilient.
When you choose Siraya Tech, you are choosing a material that disperses kinetic energy away from the glass corners of your device.
Outstanding Impact Resistance For Daily Drops
Stop printing brittle cases that crack the first time they hit the floor.
- Superior Shock Absorption: Our filament is formulated with excellent impact resistance, meaning it compresses upon impact to cushion the blow rather than transferring the shock to your phone's internal components.
- Tough Durability: Whether you drop it on concrete or it gets crushed in a bag, this material boasts high durability and toughness to survive the daily abuse we put our mobile devices through.
- Ideal for Bumper Cases: The enhanced resilience makes it perfect for printing thick corner bumpers that provide maximum protection where your phone is most vulnerable.
Enhanced Flexibility For A Perfect Fit
Getting a printed case onto a phone shouldn't feel like wrestling a bear.
- Softer Than Standard TPU: Compared to common 95A filaments, our Flex 85A offers superior flexibility, making it incredibly easy to stretch the case over the buttons and corners of your phone without snapping the print.
- Snug Grip: This flexibility ensures the case snaps back to its original shape instantly, hugging the device tightly so it never slips off unintentionally.
- Tactile Feel: The material provides a rubber-like grip that feels secure in your hand, reducing the likelihood of drops happening in the first place.
Print Custom Designs Faster Using High-Speed TPU Phone Case Filament
Creating custom phone cases is a popular business and hobby, but waiting hours for a single flexible print kills productivity.
We solved this by engineering a TPU phone case filament that flows smoothly and adheres reliably, allowing you to print complex textures and patterns at speeds that leave other flexible materials in the dust.
Five Times Faster Production Speed
You can now print a new case for every outfit or customer order without the long wait times.
- 5x High-Speed Printing Performance: Our formula is designed to print up to 5 times faster than comparable TPU filaments while maintaining the high-quality surface finish needed for a premium accessory.
- Smooth Extrusion: We specially formulated this material to extrude more easily, preventing the jams and clogs that often ruin intricate phone case designs mid-print.
- Compatible With Most Printers: Whether you have a high-end direct drive machine or a standard setup, our filament ensures a smoother printing process so anyone can make professional-grade accessories at home.
Effortless Printing For Complex Geometries
Phone cases often have overhangs, button cutouts, and charging port holes that are tricky to print.
- Excellent Layer Adhesion: The layers bond tightly together, ensuring that thin areas around the volume buttons or charging ports don't delaminate or tear after repeated use.
- Better Bed Adhesion: The material sticks firmly to the build plate to prevent warping at the corners, ensuring your case is perfectly flat and fits the phone dimensions exactly.
- Detailed Textures: The ease of printing allows you to produce cases with intricate grip patterns or personalized text that looks sharp and clean.
Recommended Slicer Settings for Phone Cases
To get maximum protection without making the case too bulky, use these optimized print settings:
| Parameter | Setting Value | Why? |
|---|---|---|
| Wall Line Count | 3 - 4 Perimeters | Increases side impact protection and bumper strength. |
| Infill Density | 20% - 40% (Gyroid) | Gyroid infill acts as a cushion/spring during drops. |
| Top/Bottom Layers | 4 Layers | Ensures a smooth, watertight back surface. |
| Print Speed | 40 mm/s | Ensures clean overhangs for buttons and charging ports. |
FAQs About TPU Phone Case Filament
Is this filament soft enough to press phone buttons easily?
Yes. Because our TPU phone case filament is formulated with enhanced flexibility (85A Shore hardness) compared to standard 95A TPU, the button covers on your printed case will be softer and easier to press, providing a better tactile click.
Will a case printed with this TPU loosen over time?
No. High-quality TPU has excellent elastic memory. You can stretch it to put the case on and take it off hundreds of times, and it will return to its original shape, keeping a tight fit on your device.
Can I print wireless charging compatible cases?
Absolutely. TPU is non-conductive and does not interfere with wireless charging signals. As long as you design your case with an appropriate thickness (usually under 3mm), wireless charging will work perfectly through our material.
How thick should I print a TPU phone case?
For the best balance of protection and flexibility, we recommend a wall thickness of 1.5mm to 2mm. Bumpers on the corners can be thicker for added shock absorption.
