ABS filament is the material of choice for creating strong and resilient parts, as its durability allows it to be incredibly heat resistant. Perfect for when you need a reliable result!
Sensitivity towards Wrapping
ABS is supposed to be more sensitive toward wrapping than PETG filaments. The melting point for ABS is quite higher than that of the PETG filaments. ABS filament can easily bear a temperature of about 100 degrees Celsius. It is an extruded plastic that can solidify fast and hence can be warped up quite easier.
The temperature management for the ABS filament is a bit more tricky than that of the PETG filaments. If you are planning to work with ABS filaments by yourself, you need to be a professional and should need to have experience in handling it perfectly.
The temperature controls for ABS filaments for 3D printing are a bit harder to control. One needs to take on the heat bed for higher temperatures for ABS filaments whereas if we talk about PETG filaments you can get a random print without heating the bed. PETG can work efficiently with a heated bed at 70 degrees Celsius but if we talk about the ABS filaments, you have to raise the temperature of the heated bed to about 100 degrees Celsius.
