OzFDM Heat Deflection Temperature Chart

What is HDT and how is it measured?

HDT stands for Heat Deflection Temperature, which is a measure of a material's ability to withstand deformation under heat. It is an important property to consider when selecting a filament for 3D printing or any other high-temperature application. HDT is typically measured using a standardized test method called ISO75 (Similar to ASTM D648).

The test involves subjecting a sample of the material to a gradually increasing temperature while applying a specified load. The temperature at which the sample deforms by a specified amount is recorded as the HDT. The higher the HDT value, the better the material's heat resistance.

Why is HDT so important in Australia?

Australia experiences high temperatures and extreme weather conditions, making it crucial to choose materials with good heat resistance. Whether you're 3D printing functional parts, manufacturing components for automotive or aerospace industries, or creating outdoor products, selecting a filament with a high HDT is essential for ensuring the longevity and performance of your creations.

Using a filament with a low HDT in high-temperature environments can lead to deformation, warping, or even failure of the printed parts. By understanding the HDT of different filaments, you can make informed decisions and choose the right material for your specific application.

Choosing the right filament with the help of the HDT chart

When it comes to selecting the right filament for your application, it's important to consider the HDT values of different materials. A helpful tool in this process is the HDT chart, which provides a comparison of various filaments and their respective HDT values.

The HDT chart allows you to identify filaments that can withstand higher temperatures, making them suitable for applications that require heat resistance. For example, if you're printing parts for a car engine, you would want to choose a filament with a high HDT to ensure the printed parts can withstand the heat generated by the engine.

Additionally, the HDT chart can help you understand the limitations of different filaments. Some materials may have a high HDT but are more difficult to print with, while others may have a lower HDT but offer better printability. By considering both the HDT and other properties of the filament, you can make an informed decision based on your specific requirements.

In conclusion, understanding HDT and its importance in high-temperature environments is crucial for choosing the right filament for your application. By referring to the HDT chart and considering other properties of the filament, you can ensure that your 3D printed parts or other creations can withstand the heat and perform optimally in their intended environment.
