Inslogic Pre-Dried TPU Filament 1.75mm 90A Black - Flexible, Tough

In this review of Inslogic Pre-Dried TPU Filament 1.75mm, the bottom line is simple: this filament is for makers who need a dependable, flexible material that prints consistently and holds up in wearable and protective applications. Our review finds the biggest reason to buy is the combination of pre-dried packaging and a Shore 90A formulation that delivers strong rebound and durability out of the spool, reducing failed prints and post-print headaches for routine functional parts.

Key Features

• Flexible & Durable TPU: Shore 90A provides high elasticity and strong rebound so printed parts return to shape after bending and stretching.
• Tear & Impact Resistant: The material is soft yet tough enough to withstand impacts and repeated stress, suitable for protective and wearable prints.
• Long-Lasting & Wear-Resistant: Printed parts maintain strength and surface smoothness over time even under frequent use, extending part life.
• UV & Heat Resistant: The filament resists yellowing and brittleness from sun and heat exposure, keeping outdoor parts stable.
• Skin-Friendly & Hygienic: Zinc-based additives reduce irritation risk, making it a safe option for watch bands, handles, and shoe parts.
• Smooth & Reliable Printing: Pre-dried for 36 hours and vacuum-packed to ensure dryness, it prints reliably at typical TPU temperatures of 220-240C.

Who It's For

This filament suits hobbyists and small-business makers who print flexible functional parts like gaskets, wearable straps, protective bumpers, phone cases, and flexible connectors. It is particularly useful for those who want a balance of softness and toughness without frequent filament drying and who run common FDM printers that accept 1.75mm flexible filament.

Those who need ultra-soft elastomers for complex medical applications or extremely high-temperature engineering plastics should look elsewhere, as this product is optimized for general-purpose flexible parts rather than specialty elastomers or high temperature polymers beyond typical TPU performance.

Pros & Cons

Pros

• Pre-dried and vacuum-packed to reduce moisture-related print failures and improve first-layer reliability.
• Shore 90A hardness balances elasticity and rebound for durable, shape-retentive flexible parts.
• Resistant to UV and heat so outdoor and warm-environment prints stay stable longer.
• Skin-friendly additives make it a safer option for items in prolonged contact with skin.

Cons

• As a firmer TPU (90A), it is less suitable for prints that require very soft, jelly-like flexibility.

Our Verdict

Inslogic Pre-Dried TPU 1.75mm is a strong choice for users who need reliable flexible filament that prints well and endures wear, impact, and sunlight. It offers excellent value for makers producing wearable straps, protective parts, or structural flexible components, thanks to pre-drying and a balanced Shore 90A formulation.

Frequently Asked Questions

Is this filament easy to print on standard FDM printers?
Yes, it is compatible with most FDM printers and prints best at 220-240C; pre-dried packaging helps reduce common moisture issues.

Can I use this TPU for wearable items that touch skin?
Yes, zinc-based additives are included to reduce irritation, making it suitable for watch bands, handles, and similar contact items.

Will prints hold up outdoors?
The filament resists UV and heat-induced yellowing and brittleness, so parts maintain stability in outdoor settings.
