Description

Are you familiar with Nitinol? It’s known as “Shape-memory wire”, meaning it is a wire that can be formed at a high temperature. It can then be mangled or reshaped, then upon re-heating, it springs back into the original shape. ESun’s e4D is a similarly-behaving Shape-Memory Polymer. Print with it like normal, then take your model and warm it in a 50ºC hot-water bath. Reshape it and hold the form until it cools again, then when you re-heat it, it springs back into the original printed shape again! Very cool!

Features:

• Shape memory: after submerging in 45-90ºC water, the material becomes soft and can be reshaped. It hardens in room temperature and keeps its form. Submerge in hot water again and it will convert back to its original shape.
• Low odor
• No clogging or tangling
• Minimal warping
• No bubbles

Specifications:

• 1.75mm nominal diameter (spec’d +/- 0.05, but is in practice closer to +/- 0.03)
• 0.5kg spools on LARGE diameter (easy unspooling) reels, vacuum sealed with desiccant
• Suggested build parameters:
  • Print temperature 200-210 ℃
  • Base temperature: 35-50 °C
  • Print speed: 40-90 mm/s

ESun is a top supplier of 3D printer filament, and we’re happy to be carrying their inventory. They are not some fly-by-night operation; eSun is an active part of the 3D printer community, and you’ll often see them represented at Maker Faires and 3D Printer Expos. We’ve even been to their labs at the Shenzhen University grounds where they develop and test their product. They take excellent care with their production methods, and each spool comes vacuum sealed in a pouch with moisture-absorbing desiccant.

In short, ESun knows their stuff. We’re extremely happy with the quality and consistency of their material.
