Who it fits

Key specs explained for this filament

Filament Diameter: 1.75mm

This is the standard width for most desktop FDM 3D printers. You need this exact size to fit your extruder gears. If your printer uses 2.85mm or 3mm filament, this spool will not work. Check your printer manual to confirm the required diameter before buying. Using the wrong size causes feeding errors and failed prints. Most consumer-grade machines rely on this 1.75mm standard for reliable operation.

Dimensional Accuracy: +/- 0.02mm

This tight tolerance ensures the wire stays uniform throughout the spool. Consistent thickness prevents jams and ensures steady extrusion. You get smoother surfaces and fewer clogs because the extruder pushes the same amount of material every time. Compare this to cheaper filaments with wider variances. Higher accuracy leads to better print quality and less need for manual flow calibration during your projects.

Shore Hardness: 95A

This rating defines the flexibility of the TPU material. A 95A hardness offers a balance between softness and structural integrity. It is flexible enough for phone cases or hinges but durable enough for functional parts. Softer TPU (lower numbers) bends easily but lacks strength. Harder TPU (higher numbers) is rigid. This 95A grade suits you if you need resilient parts that can withstand impact without breaking permanently.

Surface Finish: Glossy smooth

The printed objects will have a shiny, polished appearance rather than a matte or rough texture. This finish makes your prints stand out visually, especially with the rainbow color transitions. You do not need post-processing like sanding to achieve a clean look. The glossy surface also resists dirt better than matte finishes. This is ideal for decorative items or prototypes where visual appeal matters as much as function.

Design and build specs

The listing describes this as a 1.75mm TPU filament with a 95A Shore hardness. This rating indicates a flexible material that stretches up to three times its original length. You get a balance of softness and durability, which suits DIY projects needing resilience. The surface finish is listed as glossy and smooth. This aesthetic choice helps your prints stand out visually without requiring post-processing. The material is transparent with a rainbow color effect, allowing for multicolor prints from a single spool.

According to the listing, the filament maintains a dimensional accuracy of +/- 0.02mm. This tight tolerance ensures consistent extrusion and reduces the risk of clogs or jams in your extruder. The product weighs 1kg net, with a total shipping weight of 2.2 pounds. It is packaged in a vacuum-sealed spool to protect against moisture. The listing notes that the raw material originates from the USA. This detail suggests consistent quality control in the manufacturing process.

You must ensure your printer supports 1.75mm filament. The listing specifies compatibility with short-range extrusion FDM printers. Printing temperatures are recommended between 190-220°C. The bed temperature is optional, ranging from 0-60°C. You should dry the filament before use for best results. Proper storage in a sealed dry environment is required to maintain flexibility and surface finish. These specs define the physical handling and setup requirements for your workflow.

Setup and everyday use

Loading this filament into your printer requires standard FDM extruder gears compatible with 1.75mm diameter wire. The listed dimensional accuracy of +/- 0.02mm helps ensure smooth feeding into the hotend. This consistency reduces the risk of clogs during the initial setup phase. You should verify that your printer supports flexible materials, as TPU demands specific handling. The listing recommends a printing temperature range of 190 to 220℃. Bed temperature is optional, with a suggested maximum of 60℃. For optimal results, the data suggests a layer height of 0.15mm. This setting balances detail with the material’s flexibility. Before loading, ensure the filament is dry. The manufacturer states the material is completely dried before packaging and vacuum sealed. However, proper moisture control is critical for maintaining extrusion quality. If you store the spool after use, keep it in a sealed dry environment. The rainbow color effect means you will see shifting hues as you print, rather than uniform solid colors. This feature allows for unique visual outcomes in a single spool. The glossy smooth finish appears directly from the printer, requiring no post-processing for shine. The 95A Shore hardness indicates the material stretches up to three times its original length. This elasticity is useful for parts that need to bend without breaking. You should pass the filament through a fixed hole to avoid tangles during long prints. The neat winding and tangle-free design simplify daily operation. This setup supports continuous printing for arts, crafts, and DIY projects.

Before You Buy This Filament

You need a reliable FDM printer that handles flexible materials well. Verify your extruder supports 1.75mm wire and has strong gears to push this soft TPU. This filament works best with direct drive systems, though some bowden setups manage it if tuned carefully. You must keep the spool dry. Moisture ruins layer adhesion and causes bubbling. Store it in a sealed container with desiccant after opening. The glossy rainbow finish looks great but requires careful retraction settings to avoid stringing. If your printer struggles with flexibility, this might not be the right choice. You should also consider your printing speed. High speeds can cause jams with 95A hardness. Pair this with a sturdy build plate, ideally heated to sixty degrees Celsius, to prevent warping. This option fits users who want durable, colorful parts rather than rigid prototypes. It complements standard PLA spools by adding versatility to your toolkit.

Check before you buy

• Confirm your printer uses 1.75mm filament diameter.
• Check if your extruder handles flexible TPU well.
• Ensure you have dry storage for the spool.
• Verify your bed can reach sixty degrees Celsius.
• Prepare to adjust retraction settings for stringing.
