PLA Soft, Nature

purefil PLA Soft Filament – A Smarter Choice for Flexible Printing

purefil PLA Soft Filament is a specially formulated flexible PLA with exceptional impact resistance. With 35 times higher elongation at break than standard PLA, this filament offers a simple-to-print alternative to TPE, making it ideal for both beginners and professionals looking for a durable and flexible 3D printing material.

Why PLA Soft is a Game-Changer?

Unlike traditional rigid PLA, PLA Soft retains flexibility while still benefiting from easy printability and low warping. A heated bed is recommended but not required, and prints can adhere directly to a glass plate. For best results, we suggest using a cooling fan while printing.

Main Advantages

• Extreme flexibility for impact-resistant parts
• 35× higher elongation than PLA for enhanced durability
• Beginner-friendly and easier to print than TPE
• Prints directly on glass without additional adhesion aids
• Low flammability makes it safer than ABS
• Doesn’t fade over time, retaining color and integrity
• Industrial biodegradability makes it more sustainable than traditional plastics

Applications

PLA Soft is perfect for shock-absorbing components, flexible hinges, protective covers, and ergonomic grips. Whether you're printing wearable prototypes or soft-touch enclosures, this filament delivers outstanding performance with minimal print failures.

Sustainability & Disposal

PLA Soft is industrially biodegradable under specific conditions and complies with European Regulation No. 10/2011 on plastic materials for food contact. However, proper decomposition requires specific environmental conditions found only in industrial composting facilities. In natural environments, PLA Soft does not break down easily.

For this reason, we do not recommend composting PLA Soft filament or printed parts at home. Instead, they should be disposed of in household waste to ensure proper handling.
