Description
eSUN 4D Filament — Heat-Deformable and Recoverable 3D Plastic Filament
eSUN 4D Filament is an innovative 3D printing material that transcends the limitations of common PLA and ABS. With its Shape Memory properties, printed objects can be reshaped when soaked in hot water and will automatically return to their original form when soaked in hot water again. It is ideal for creative projects, research, and applications requiring adjustable shapes.
🔬 What is 4D Filament?
4D = 3D Printing + 4th Dimension (Time/Shape Change). Objects printed with 4D filament possess "shape memory" — they can be bent and reshaped when exposed to heat (hot water 45–90°C), and when immersed in hot water again, the object will automatically revert to the shape it was originally printed in.
✅ Key Features of eSUN 4D Filament
-
Up to 95% Shape Memory — Accurate recovery every time.
-
Easy to Reshape — Softens enough for shaping after just 1–3 minutes in hot water.
-
Infinitely Reusable — The reshaping and recovery process can be repeated multiple times.
-
Easy to Print — Similar settings to PLA, no enclosed printer needed.
-
Safe — Odorless and BPA-free.
🎯 Ideal for What Applications?
- Soft Robotics and Smart Materials Research
- Educational / STEM projects requiring moving models
- Demonstration models requiring shape change
- Creative DIY projects needing customizable materials
- Prototypes requiring flexibility and recovery
📋 How to Use (Step-by-Step)
-
Print the Object — Print your desired model as usual, following the parameters below.
-
Reshape — Soak the object in hot water (45–90°C) for 1–3 minutes until soft. Then, mold it into the desired shape.
-
Fix the Shape — Hold the shape until the object cools below room temperature. It will harden and retain the new shape.
-
Recover Original Shape — Soak it in hot water again. The object will gradually and automatically revert to its originally printed shape.
