Guide for FDM 3D Printing Material 0

3D printing has revolutionized the manufacturing industry, and the use of plastic as a printing material has been a significant contributor to this change. There are several types of plastic materials used for 3D printing, each with unique properties that make them suitable for different applications. Here, we will discuss the most commonly used types of 3D printing plastics, the best printing temperatures, the recommended bed and nozzle temperatures, and print settings for each.

Printing with PETG 24

Printing with PETG (Polyethylene Terephthalate Glycol) filament has become increasingly popular among 3D printer enthusiasts due to its versatility, strength and durability. PETG is a thermoplastic that can be easily molded and extruded when heated, making it an ideal material for 3D printing. In this article, we will go over the best settings for printing with PETG to help you achieve high-quality prints every time.

Bed Temperature: A bed temperature of around 70-80°C is ideal for printing with PETG. This temperature range helps the filament adhere properly to the bed and prevents warping, which can be a common issue when printing with PETG.
Nozzle Temperature: Nozzle temperature is one of the most important settings when it comes to printing with PETG. A temperature range of 225-235°C is recommended for most brands of PETG filament. However, you should always refer to the filament manufacturer's recommendations as different brands of PETG filament may have different temperature requirements.
Print Speed: The print speed you choose will largely depend on the complexity of the object you are printing. For smaller, simpler objects, you can print at a faster speed. For larger, more complex objects, a slower print speed is recommended to help ensure the filament has time to cool and prevent any defects from forming. A speed of 40-60mm/s is a good starting point for printing with PETG.
Cooling: Proper cooling is crucial when printing with PETG. This material requires adequate cooling to prevent warping and other defects from forming. A fan should be used to cool the object as it is being printed, and the fan speed should be adjusted depending on the complexity of the object being printed.
Retraction: Retraction is the process of pulling the filament back into the hot end to prevent stringing, which can be an issue when printing with PETG. The amount of retraction you use will depend on the brand of filament you are using, but a good starting point is around 4mm.
Bed Adhesion: Bed adhesion is another important factor when printing with PETG. A properly calibrated bed and high-quality adhesion material, such as painters tape or hair spray, is recommended to help the filament stick to the bed and prevent warping.

In conclusion, printing with PETG is relatively easy, but it requires a careful balance of temperature, speed, and cooling to achieve high-quality prints. By following the recommended settings outlined in this article, you can be confident that your prints will be successful every time. Of course, as with all 3D printing, it is always a good idea to do some test prints before diving into a larger project to fine-tune your settings to your specific printer and filament.
