When comparing iSANMATE vs EONO3D 3d printing filament, you face two distinct material choices. Both brands offer 1.75mm spools with vacuum-sealed packaging to protect against moisture. The main difference lies in the polymer type. iSANMATE provides ASA, a rigid plastic designed for outdoor durability and UV resistance. EONO3D offers TPU, a flexible thermoplastic polyurethane ideal for parts that need to bend or absorb impact. Your choice depends on whether you need structural strength or flexibility.

Which one should you choose?
Choose iSANMATE Red ASA Filament 1.75mm 1kg if
- You need parts that withstand UV exposure and weather for outdoor use.
- You want a rigid material with a wider recommended print speed range.
- You require a specified dimensional accuracy of +/- 0.02mm for functional parts.
Choose EONO3D 95A 1.75mm Black TPU Filament (1kg) if
- You are printing items that must bend, such as phone cases or shoe insoles.
- You prefer a matte black finish for professional-looking flexible parts.
- You need a material with a listed Shore Hardness of 95A for balanced flexibility.
Verdict: Choose iSANMATE ASA if you are building durable, rigid components that will face harsh environmental conditions. Select EONO3D TPU if your project requires flexible, impact-resistant parts like gaskets or wearables. The right choice depends entirely on whether your final product needs to stay hard or bend.
ASA Rigidity Versus TPU Flexibility
Material Type
iSANMATE offers ASA, a rigid engineering plastic designed for outdoor functional parts. It provides high mechanical strength and stability. EONO3D provides TPU 95A, a flexible thermoplastic polyurethane. This material bends and absorbs impact rather than resisting deformation. You choose ASA for rigid components like automotive brackets or outdoor housings. You select TPU for items requiring elasticity, such as phone cases, gaskets, or wearable bands. The fundamental difference is structural behavior under stress, defining the entire application scope for each spool.
Print Speed
iSANMATE ASA supports a maximum print speed of 100mm/s. This allows for faster production of rigid models when paired with a capable printer. EONO3D TPU recommends a slower range of 30-60mm/s. Flexible materials require reduced feed rates to ensure smooth extrusion and prevent tangles or grinding in the extruder. The iSANMATE specification permits nearly double the speed of the EONO3D recommendation. If rapid output of rigid parts is your priority, the ASA specification is superior. For flexible prints, the slower pace ensures quality.
Dimensional Accuracy
iSANMATE specifies a dimensional accuracy of +/- 0.02mm for its ASA filament. This tight tolerance ensures consistent layer thickness and precise geometric dimensions for functional parts. The EONO3D product description highlights excellent dimensional accuracy and consistent 1.75mm diameter feeding. However, it does not provide a specific numerical tolerance value. The iSANMATE data offers a concrete metric for precision requirements. You can rely on the +/- 0.02mm specification for tight-fitting assemblies. The EONO3D filament appears reliable, but the lack of a specific number makes direct comparison difficult.
Shore Hardness
EONO3D explicitly lists a Shore Hardness of 95A for its TPU filament. This metric quantifies the balance between softness and rigidity, similar to a shoe sole. iSANMATE does not list a hardness value, as ASA is a rigid material that does not bend. The 95A rating helps you predict how the part will flex under load. This specification is critical for selecting the right flexibility for wearables or impact-resistant covers. The iSANMATE ASA is not measured by Shore hardness, making this a unique advantage for the EONO3D product when evaluating flexibility.
Surface Finish
EONO3D specifies a matte surface finish for its black TPU filament. This provides a professional, non-reflective look suitable for automotive or cosmetic parts. The iSANMATE ASA listing does not define a specific surface finish in the provided data. ASA typically produces a semi-gloss or matte finish depending on printing parameters, but the manufacturer does not state a default. The EONO3D specification gives you a clear expectation of the final aesthetic. If a consistent matte look is required without post-processing, the EONO3D data is more specific.
Choose iSANMATE or EONO3D for your needs
Outdoor part makers needing weather resistance
You need ASA filament for parts exposed to the elements. iSANMATE offers UV and weather resistance to prevent degradation. The rigid material provides mechanical stability in varying temperatures. This makes it ideal for outdoor functional components that must withstand long-term exposure without breaking or fading.
Printers making flexible wearable or impact parts
You require flexibility for phone cases, shoe insoles, or drone parts. EONO3D TPU 95A balances softness and rigidity. It absorbs impact and bends without breaking. The 95A Shore hardness ensures the part survives repeated compression. This material is perfect for functional flexible prints that need durability.
Users printing in enclosed spaces for stability
ASA printing benefits from a closed environment to reduce warping. iSANMATE recommends this setup for optimal results. The filament maintains dimensional accuracy of plus or minus 0.02mm. You get consistent prints with high thermal resistance. This approach ensures your functional parts remain stable and precise during the printing process.
