SUNLU TPU Key Specs Explained

Material Type: TPU

This stands for thermoplastic polyurethane, a flexible plastic material. It offers a balance of softness and resilience, making it ideal for items that need to bend without breaking. You can use it for wear-resistant parts, robotics components, and flexible fashion accessories. Unlike rigid PLA or ABS, TPU absorbs impact and resists daily wear and tear.

Shore Hardness: 95A

This value measures the stiffness of the filament on a standardized scale. A rating of 95A indicates a firm but flexible material, similar to a rubber shoe sole. It provides enough give to withstand collisions during sports or daily use, while still maintaining structural integrity. This hardness level is suitable for functional prototypes and durable consumer goods.

Filament Diameter: 1.75mm

This is the standard width for most desktop FDM 3D printers. A consistent diameter ensures smooth feeding through the extruder and prevents clogs. It allows you to use this filament with almost all common 3D printers, regardless of the brand or model. Standardizing the size helps maintain uniform extrusion rates for reliable print quality.

Dimensional Accuracy: +/- 0.03mm

This specification indicates how closely the actual filament diameter matches the nominal 1.75mm size. A tight tolerance of plus or minus 0.03mm ensures consistent flow from the nozzle. This precision reduces the risk of under-extrusion or over-extrusion, leading to smoother surfaces and stronger layer adhesion. It is crucial for maintaining dimensional accuracy in your final printed parts.

Net Weight: 1kg

This indicates the total amount of filament included in the spool. One kilogram provides a substantial volume of material for creating larger or multiple smaller objects. It is a standard size for hobbyists and professionals, offering enough supply for extended projects without frequent refills. This weight balances portability with sufficient material for various flexible printing needs.

Design and Build Quality

According to the listing, the filament comes in a 1kg spool with dimensions of 2.24 inches in width and 7.68 inches in both height and length. The total shipping weight is 2.2 pounds. This compact form factor allows for easy storage on most desktop 3D printers. The spool design is standard, fitting directly into the filament path of almost all 1.75mm FDM machines. This wide compatibility means you do not need to modify your printer to use this material.

The material itself is a flexible thermoplastic polyurethane with a Shore hardness of 95A. This specific hardness strikes a balance between softness and resilience. It is not as rigid as PLA or ABS, nor is it as soft as lower durometer TPU grades. This makes the filament suitable for items that must bend without breaking, such as phone cases, gaskets, or robotic joints. The material is described as wear-resistant and oil-resistant, which adds to its durability in daily use.

The listing notes that the filament features excellent layer adhesion and a smooth finish. These traits help prevent print failures, which are common with flexible materials. The packaging is vacuum-sealed to keep the filament moisture-free from the factory. This preserves the quality of the TPU, ensuring consistent flow and reliable prints when you load it into your printer.

Setup And Daily Use Guide

Loading this filament is straightforward. The spool fits standard 1.75mm FDM printers. Its tight dimensional accuracy of +/- 0.03mm ensures it feeds smoothly through most extruders without jamming. You do not need special adapters for standard setups.

For daily printing, the listing recommends a nozzle temperature between 210°C and 230°C. The bed should be set to 50°C to 60°C. These moderate temperatures help manage the material’s flexibility. You can push the print speed up to 120mm/s. This is faster than typical TPU prints, which often struggle with long extrusion paths. The filament is designed to handle these speeds while maintaining layer adhesion.

The 95A Shore hardness indicates a balance between softness and resilience. This means your prints will bend under pressure rather than snap. This property makes the material suitable for items that face wear, such as phone cases or robotic joints. The material is also oil-resistant and anti-aging, which helps parts last longer in daily use.

Storage is simple. The filament arrives in vacuum-sealed packaging. This keeps moisture out until you open it. You should store the spool in a dry place after opening to maintain quality. The tight seal protects the material from humidity, which can cause bubbling or poor layer bonding during printing. With proper storage and the recommended settings, you get consistent, flexible results. The wide color options, including black, white, and clear, let you choose finishes that match your project needs. The smooth finish and excellent layer adhesion reduce the need for post-processing.

Before You Buy TPU Filament

You should verify your printer’s extruder type before loading this spool. Direct drive systems handle 95A TPU most reliably. Bowden setups may require slower speeds to prevent grinding. Keep the vacuum-sealed packaging intact until you are ready to print. Moisture absorption degrades layer adhesion quickly, so store any unused filament in a dry box with silica gel. This material suits flexible cases, gaskets, and wear-resistant parts better than rigid PLA or ABS. It does not replace stiff structural components. Check your nozzle size; smaller nozzles like 0.2mm increase print time significantly at the recommended speeds. If you already own a printer with a hardened steel nozzle, this filament will work well. Ensure your bed surface provides good initial adhesion, as TPU can stick too firmly to glass without proper separation agents. This filament fits into the broader category of flexible materials alongside other TPU and TPE options. It offers a middle ground between softness and durability. You need to adjust slicer settings for retraction to avoid stringing. Regular maintenance of your extruder gears helps prevent jams with this flexible material.

Check before you buy

• Confirm your printer uses a direct drive extruder for best results
• Ensure you have a dry storage box for moisture protection
• Verify your nozzle is hardened steel to resist abrasion
• Check that your bed surface allows for easy part removal
• Prepare slicer settings for low retraction to prevent stringing
