Who it fits
Good fit for
You should choose this filament if you print functional items like phone cases, gaskets, or wearable devices. The 95A hardness suits projects needing bendability without tearing. It works well on direct drive printers and adjusted Bowden setups like Creality Ender-3 or Prusa models. If you need durable, wear-resistant parts for outdoor or daily use, this spec profile matches your needs for reliable, flexible outputs.
Who should skip it
Skip this option if you require rigid, high-strength structural parts. The 95A TPU is designed for flexibility, not stiffness. You should also avoid it if your printer lacks a direct drive or a well-tuned Bowden system, as flexible filaments can jam in unsupported extruders. Additionally, if you cannot maintain a dry storage environment or dry the filament at 50°C before use, you may experience bubbles and poor layer adhesion.
Verdict: This TPU offers a practical balance of flexibility and durability for functional prints. It suits users with compatible extruders who need wear-resistant, bendable parts.
Yousu TPU 95A Key Specs
95A Shore hardness
This rating indicates the material is flexible but retains structural integrity. You get parts that bend without tearing, making them ideal for items like phone cases, shoe soles, or wearable accessories. It balances softness with durability, ensuring your prints withstand daily wear and tear better than rigid plastics. This hardness level suits users needing shock absorption or elastic components in their functional projects.
1.75mm diameter
This is the standard filament width for most FDM 3D printers. It ensures compatibility with a wide range of machines, including direct drive and well-tuned Bowden systems. You do not need special hardware to use this size. It allows you to swap this filament into your existing printer without adjustments to the extruder mechanism, making it a safe choice for general-purpose flexible printing.
1kg spool weight
Each roll contains one kilogram of material, providing a substantial amount for medium to large projects. This weight balances portability with volume, allowing you to print multiple smaller parts or one larger object in a single load. It is a standard unit size for comparison, helping you estimate how many layers or parts you can produce before needing to reload or purchase additional filament.
Vacuum-sealed with desiccant
The packaging prevents moisture absorption, which is critical for TPU to avoid stringing and bubbles during printing. You get stable flow and smooth surfaces right out of the box. If you store the filament, this seal maintains quality for up to one year. For opened spools, you may need to dry it at 50°C for seven hours to ensure optimal print results and layer adhesion.
Design And Build Overview
According to the listing, the Yousu TPU 95A filament is constructed from a flexible thermoplastic polyurethane material. This composition provides a 95A Shore hardness rating, which defines the balance between suppleness and structural integrity. You can expect parts that bend freely without tearing, making the material suitable for items requiring movement or impact resistance, such as phone cases, wearable devices, and shock absorbers. The material is also noted for its wear resistance, which helps prevent fragile prints from breaking during handling or daily use.
The product is supplied as a 1.75mm diameter spool containing 1kg of filament. The specific model listed is the YS-TPU-Black-1.75-1.0, packaged in a vacuum-sealed container with desiccant to maintain quality. This packaging choice is critical for flexible filaments, as moisture absorption can cause bubbling and stringing during extrusion. The listing indicates that the spool maintains its quality for one year if unopened, but suggests drying the filament at 50°C for seven hours after opening to ensure optimal performance.
While the listing does not detail the spool's physical dimensions beyond the filament height variations in other options, the 2.2-pound weight suggests a standard industrial spool size. This design allows for stable feeding on most FDM 3D printers, particularly direct drive systems. The smooth surface and low stringing characteristics mean you can achieve clean prints with minimal post-processing. The material is compatible with well-tuned Bowden systems as well, offering flexibility in printer choice for your functional projects.
Setup And Daily Use Guide
Setting up this filament begins with storage. Each spool arrives vacuum-sealed with desiccant to block moisture. This packaging preserves quality for one year if unopened. You must handle the spool carefully to maintain the seal. If you open the package, you need to dry the filament at 50°C for seven hours before reuse. This step prevents bubbles and stringing during your first prints. Proper drying ensures stable feeding and smooth flow. You should store the filament in a dry environment after drying to keep it ready for future projects. Printing this material requires compatible hardware. It delivers optimal performance on direct drive printers. The smooth surface and stable feeding also work well with well-tuned Bowden systems. You can use it with popular models like the Bambu Lab, Creality Ender-3, K1 series, Anycubic Kobra, ELEGOO Neptune, Flashforge, and Prusa machines. Daily use involves loading the spool and adjusting your slicer settings for flexible materials. The low stringing feature helps you achieve clean prints with minimal post-processing. You get parts with excellent layer adhesion and a smooth finish. The 95A Shore hardness allows for flexible, durable components. You can print movable parts, phone cases, soles, and wearable devices. The material resists tearing and wear, making it suitable for outdoor or high-use items. You benefit from consistent extrusion and minimal jams if your printer is properly adjusted. This setup process ensures reliable results for functional applications.
Before You Buy This Filament
Before you buy this filament, verify your printer’s extruder type. The listing notes best performance on direct drive systems. It also works with well-adjusted Bowden setups, such as certain Creality or Prusa models. You should check your specific machine’s capabilities to ensure stable feeding. Since this is a flexible material, you may need a slower print speed setting to avoid jams. Proper storage is critical. Keep the vacuum seal intact until you are ready to print. If you open the package, dry the filament at 50°C for seven hours to remove moisture. This step prevents bubbles and stringing during use. This spool sits alongside other flexible options in our 1 product guide. Unlike rigid PLA, this TPU offers wear resistance and bendability. It suits projects requiring durability, like phone cases or shoe soles. Consider your end-use carefully. If you need rigid structural parts, this material is not suitable. For flexible, durable components, it is a strong candidate. Always match the 1.75mm diameter to your printer’s requirements. Check your extruder gear for wear, as flexible filaments can stress older mechanisms.
Check before you buy
- Verify your printer uses direct drive or a well-tuned Bowden system.
- Ensure your extruder gear is in good condition for flexible materials.
- Check that your printer accepts 1.75mm diameter filament.
- Confirm you have a filament dryer for moisture removal.
