Hello everyone! Today we are going to talk about a topic that sounds a bit “hard core” – the innovative application of polyurethane sponge hardener in 3D printing materials. Don’t be scared by this long name. In fact, there are many interesting stories and infinite possibilities in the future hidden behind it. Imagine that future 3D printing can not only print soft toys, but also hard mechanical parts and even complex building structures. All of this is inseparable from the “hardening agent” we are going to talk about today.

What is polyurethane sponge hardener?

First, let’s learn what polyurethane sponge hardener is. Polyurethane (PU) is a common polymer material and is widely used in foam, coating, adhesives and other fields. As the name suggests, “hardening agent” is an additive used to increase the hardness of the material.

Properties of polyurethane sponge

Polyurethane sponge itself has the characteristics of lightweight, softness and good elasticity, and is often used to make sofa cushions, mattresses, packaging materials, etc. However, in some application scenarios, such as 3D printing, we need materials to have higher hardness and strength. At this time, hardener comes in handy.

The function of hardener

The hardener makes it tighter and harder by changing the molecular structure of the polyurethane. It’s like adding more flour to the dough to make the dough stronger. The addition of hardener not only improves the hardness of the material, but also improves its wear resistance, heat resistance and impact resistance.

The current status of 3D printing materials

Before getting to the topic, let’s take a look at the current situation of 3D printing materials. Since its inception, 3D printing technology has gone through decades of development. From the initial plastic printing to the current metal, ceramic, and biomaterial printing, the application range of 3D printing is becoming more and more wide.
