Polymaker 95A TPU Key Specs

Material Type: TPU

This stands for thermoplastic polyurethane. It is a flexible plastic that bends without breaking. You should choose this if you need parts like phone cases, gaskets, or shoe inserts. It differs from rigid PLA or ABS. The material offers good resilience and durability for functional items that must withstand repeated flexing or impact during daily use.

Shore Hardness: 95A

This number measures how stiff the plastic is. A 95A rating means the filament is quite soft and pliable. You will get parts that feel rubbery rather than hard. This level is ideal for grips, seals, and protective covers. Compare this to harder TPU options if you need structural rigidity, or softer ones for extreme flexibility.

Filament Diameter: 1.75mm

This is the standard width for most consumer 3D printers. It ensures the filament fits into the extruder gears of your machine. You do not need special hardware to run this spool. Check your printer manual to confirm it supports 1.75mm input. This size is the most common choice for reliable feeding and consistent layer deposition.

Dimensional Accuracy: ±0.02mm

This tolerance indicates how consistent the filament thickness is. A variance of only 0.02mm helps prevent clogs and under-extrusion. You will see smoother prints with fewer gaps. This precision is vital for detailed models. Compare this to cheaper filaments with wider tolerances, which often cause print failures or require frequent manual adjustments during setup.

Net Weight: 0.75kg

This is the amount of raw material on the spool. A 0.75kg roll is lighter and smaller than standard 1kg spools. It is easier to store and handle. You get less total length for printing large objects. Consider this size if you want to test the material first or have limited storage space for your supplies.

Design and build details

According to the listing, the Polymaker 95A TPU filament is made from thermoplastic polyurethane. This material choice defines the physical behavior of the printed object. With a Shore hardness of 95A, the plastic offers a balance between softness and structural integrity. You can use it for parts that must bend without snapping, such as protective covers or flexible seals. The material is not rigid like standard PLA, which limits its use for static structural components but makes it ideal for dynamic applications.

The product is packaged in a spool with a net weight of 0.75kg. The listing specifies the total package weight as 1.65 pounds, which includes the spool and packaging materials. The spool dimensions are 7.87 inches in width and length, with a height of 1.77 inches. This compact footprint allows it to fit on most standard 3D printer filament holders without requiring excessive shelf space. The filament diameter is 1.75mm, a standard size compatible with the majority of FDM printers.

Dimensional accuracy is listed at ±0.02mm. This tight tolerance ensures consistent extrusion, which is critical for flexible materials that can jam if the diameter varies. The packaging design protects the filament from moisture, a key concern for TPU. You do not need to worry about complex controls or interfaces, as the material itself is the primary variable. The build focuses on reliable delivery of a specialized polymer, ensuring you get consistent results for functional flexible prints.

Setup and Everyday Use

Setting up this filament requires attention to your printer’s extruder and hotend. The recommended nozzle temperature sits between 210°C and 230°C. You must ensure your hotend can reach and hold this range consistently. The bed temperature should be set between 25°C and 60°C. This range allows the first layer to adhere without warping, which is critical for flexible materials. The filament diameter is 1.75mm with a tight tolerance of ±0.02mm. This precision helps your printer’s feeder gears grip the material evenly. It reduces the risk of clogs or under-extrusion common with softer plastics. You should load the spool carefully. The 95A Shore hardness means the plastic is firm yet bendable. It will not feed as easily as rigid PLA. A direct drive extruder is ideal. Bowden setups may struggle with the recoil of flexible material. The listing suggests a printing speed of 40mm/s. You can push up to 80mm/s, but slower speeds yield better layer adhesion. This balance ensures strong bonds between layers. Daily use involves printing functional items like grips, seals, or protective covers. The material’s resilience allows for repeated flexing. You will notice smooth extrusion if settings match the specs. The 0.75kg spool size fits standard holders. This compact weight makes it easy to manage on most desktop printers. Consistent dimensions support reliable print quality over time. You get durable parts that withstand stress. The blue color, Hex Code #338cc7, provides a distinct look. It is suitable for prototypes needing elasticity. Ensure your printer is calibrated for flexible media. This setup prevents frustration and wasted material. The specs indicate a practical workflow for everyday flexible prints.

Before you buy this flexible filament

You need a direct drive extruder for reliable results. Bowden setups often struggle with flexible materials like this TPU. Check your printer’s maximum speed capability. The listing recommends 40mm/s, with a maximum of 80mm/s. Slower speeds ensure consistent layer adhesion. You should also verify your hotend can handle 210–230°C without clogging. This filament is not suitable for high-speed production. It fits well alongside rigid filaments for mixed-material projects. Use it for grips, seals, or protective covers. Keep the spool sealed to prevent moisture absorption. TPU is hygroscopic, so proper storage matters. Compare this option with other flexible materials in the guide. If you need extreme softness, look for lower Shore hardness options. If you need speed, consider rigid PLA. This product sits in the middle, offering durability and flexibility. It is ideal for functional prototypes that bend. Ensure your build plate is clean for good adhesion. A brim may help with the first layer. This guide helps you choose the right tool for your specific needs.

Check before you buy

• Verify your printer has a direct drive extruder
• Confirm your hotend supports temperatures up to 230°C
• Check that your printer handles speeds of 80mm/s
• Ensure you have storage for hygroscopic TPU filament
• Compare with other Shore hardness options in the guide
