Product Description
SainSmart 87A Transparent TPU Filament 1.75mm
The transparent flexible TPU consumables with a hardness of 87A are strong and durable. The printed product is softer than TPU-95A but harder than the elastic printed product, and has a certain degree of transparency.
High Resilience & Mechanical Strength
87A TPU Filament is a transparent, flexible, and elastic material with high resilience and mechanical strength (bending, tension, and compression), abrasion, and aging resistance. It is also very resistant to chemicals, water, oil, and solvents.
High Impact Resistance
It is also waterproof, cold, and UV resistant (resistant to yellowing, able to withstand sun exposure). It is good for printing footwear. Many sports shoes, such as softball shoes, golf shoes, etc. It can use 87A TPU material for sole production, or to print the entire shoe model.
Widely Application
Shoe material Machinery Automobile Electronic appliances Conveying pipeline Sporting products
Printing Tips
1. It is recommended to dry (55℃/ >4H) before printing to achieve the best printing effect. It is recommended to use it with dry box cartridges when printing.
2. It is recommended to use a dual-gear direct extruder designed for flexibility, and eFlex materials cannot be printed with a bowden extruder.
3. The nozzle may have impurities after printing for a long time. It is recommended to use it with the cleaning filament. If necessary, replace the nozzle and throat with a new one.

Flexible and Soft: Specially formulated plastic with an increased amount of flexibility, with rigid structure. Recommended for printing objects, which will be impacted more than normal ones. 1.75mm diameter, 87A hardness, 1.12 density(g/cm³).
TPU (Thermoplastic Polyurethane) is a subclass of thermoplastics that prints strong parts that are also flexible.
Suitable for Direct Extruder: There is no gap between the wire feed roller and the extruder, otherwise, the flexible material will curl and get stuck between the two, resulting in poor feeding.
Premium TPU Filament: TPU (Thermoplastic Polyurethane) is a subclass of thermoplastics that prints strong parts that are also flexible. It has a certain degree of transparency, high mechanical strength, and good properties.
Impact resistance & wide applicability: Great performance in waterproof, cold, and UV resistance, good for industrial production, medical applications, industrial arts, personal DIY, etc.
