ASA Rigidity vs TPU Flexibility
Material properties
Polymaker ASA 1.75mm Filament (1kg) is an ABS-like material designed for rigidity and strength. It offers high toughness and impact resistance, making it suitable for functional prototypes, mechanical parts, and housings that require durable performance. In contrast, Polymaker 95A TPU Filament (0.75 kg) is a flexible thermoplastic polyurethane with a Shore hardness of 95A. This flexibility allows it to produce resilient parts like grips, seals, and protective covers. You choose ASA for structural integrity and TPU for elasticity and shock absorption.
Heat resistance
The Polymaker ASA 1.75mm Filament (1kg) withstands temperatures up to 100˚C (212°F). This high heat resistance makes it ideal for outdoor applications and car accessories exposed to environmental stress. The Polymaker 95A TPU Filament (0.75 kg) does not list a maximum service temperature in the provided data. While TPU is durable, ASA’s specific thermal rating gives it a clear advantage for projects requiring stability under heat. You should select ASA if your printed parts will face elevated temperatures.
Print speed
Polymaker ASA 1.75mm Filament (1kg) supports a recommended print speed of 50mm/s. This allows for relatively quick production of rigid parts. Polymaker 95A TPU Filament (0.75 kg) has a maximum print speed of 80mm/s. Although flexible filaments often print slower, this TPU variant allows for faster extrusion rates than the ASA. If speed is your primary constraint, the TPU option offers a higher potential throughput, provided your printer handles flexible material well.
Weight and value
Polymaker ASA 1.75mm Filament (1kg) provides 1kg of material. Polymaker 95A TPU Filament (0.75 kg) provides 0.75kg. You receive more filament with the ASA option. This difference matters if you are printing large objects or require multiple iterations. The ASA spool contains 33% more material by weight. For projects requiring significant volume, the ASA filament offers greater quantity per unit, assuming comparable part sizes and infill settings.
Dimensional accuracy
Polymaker ASA 1.75mm Filament (1kg) is listed as 1.75mm in diameter. Specific tolerance data is not provided in the specifications. Polymaker 95A TPU Filament (0.75 kg) specifies a dimensional accuracy of ±0.02mm. This precise tolerance ensures consistent extrusion and reliable print quality. If you require strict adherence to diameter specifications for optimal flow, the TPU filament provides verified accuracy data. The ASA filament likely meets standard tolerances, but the TPU explicitly states its precision.
Which Polymaker Filament Fits Your Needs
Outdoor gear makers needing UV resistance
Choose ASA if you print parts for outdoor use. It offers UV and weather resistance, preventing environmental stress cracking. The material withstands temperatures up to 100°C, ensuring durability for RC planes and car accessories. You get high impact resistance and rigidity, making it ideal for functional prototypes that face harsh conditions.
Creators of flexible functional parts
Select TPU 95A for items requiring elasticity. With a Shore hardness of 95A, it balances flexibility and resilience. It is perfect for grips, seals, and protective covers. The filament ensures smooth extrusion and strong layer adhesion, producing durable components with reliable bonding. You get consistent print quality for everyday flexible parts.
Users needing high weight capacity
Pick ASA if you require more material per spool. This option comes in a 1kg package, giving you more print volume than the 0.75kg TPU alternative. The 1.75mm diameter ensures compatibility with most FDM printers. You benefit from reliable layer adhesion and strength, allowing for larger projects without frequent filament changes.

Frequently asked questions
Is Polymaker ASA filament stronger than TPU?
Yes, ASA is significantly stronger and more rigid than TPU. Polymaker ASA is designed for high toughness and impact resistance, making it ideal for functional prototypes and mechanical parts. TPU, specifically the 95A variant, prioritizes flexibility and elasticity over structural rigidity. You should choose ASA if your project requires a hard, durable shell rather than a bendable component.
Can I use Polymaker ASA for outdoor projects?
Polymaker ASA is an excellent choice for outdoor applications due to its weather and UV resistance. It prevents environmental stress cracking, ensuring longevity for parts exposed to sunlight. This filament is best suited for outdoor functional parts, such as RC plane components or exterior housings. The material withstands temperatures up to 100°C, maintaining stability in various weather conditions.
What is the difference between 1kg and 0.75kg spools?
The primary difference is the total material volume available for printing. Polymaker ASA comes in a 1kg spool, providing more filament for larger projects. The 95A TPU variant is available in a 0.75kg size, offering less material per unit. Both use 1.75mm diameter wire, but the weight difference affects how long each spool lasts during extended printing sessions.
Does Polymaker TPU filament have strong layer bonding?
Yes, Polymaker 95A TPU filament is noted for reliable, flexible parts with strong layer bonding. This characteristic ensures that printed components remain durable and do not easily separate under stress. It is ideal for makers who need elasticity and toughness. The strong adhesion between layers makes it suitable for functional prototypes that must withstand physical strain.
Is ASA filament easy to print with?
ASA requires an enclosed environment for reliable printing results. It is an ABS-like material that benefits from controlled temperatures to prevent warping. While it offers high strength, it demands specific printer settings compared to standard PLA. Users needing weather-resistant prototypes should ensure their printer can maintain the necessary heat stability for optimal layer adhesion and part quality.
Which filament is better for shock absorption?
TPU is the superior choice for shock absorption due to its inherent flexibility. The 95A variant provides elasticity that rigid materials like ASA cannot match. If your project involves grips, bumpers, or parts subject to impact, TPU will absorb energy better. ASA is designed for rigidity and strength, making it less suitable for applications requiring significant deformation or cushioning.
What colors are available for these Polymaker filaments?
The Polymaker ASA filament is available in White, specifically identified by the hex code #Dbd7d6. The 95A TPU filament is offered in Blue, with the hex code #338cc7. These specific color options allow you to match your prints to design requirements. The color is integrated into the filament, ensuring consistent appearance throughout the print.
