How do I get my prints to stick to the bed?

PLEASE NOTE: As with all flexible filament, some printers may require mods to guide the filament from feeder to nozzle as they tend to sometimes bend when being pushed due to their flexible nature.

TrueExtrude Technology 

What is TrueExtrude Technology?

TrueExtrude Technology is added to our uglyFlex filament in order to prevent stringing with 3D Printing flexible materials. "Stringing" is a very common issue with all flexible filament, and occurs when the nozzle lifts off but the the the filament acts like a "pizza cheese string" when pulled off. If you've ever used with a hot glue gun, you will have a pretty good idea of what "stringing" is, if this is your first time ordering a flexible filament to extend the capabilities of your 3D Printer beyond ABS or PLA.



   Use uglyFlex flexible 3D Printing filament to extend the capabilities of your 3D Printer. For the highest quality, low cost flexible 3D printing material available and ready to print with almost any 3d Printer. It feels and acts just like rubber. You can use it to make products that bend and flex, like pulley belts, shoe soles, phone cases and more.  Low-Stringing with easy-to-feed TrueExtrude technology. Create extremely flexible yet durable prints.

Our flexible printing filament is made of TPU, an eco-friendly material. It fits for most 3D printers that can print PLA material.


   When storing your 3d Printing filament for extended periods, place it in a resealable bag (Ziploc) along with the included silica packet (few grains of rice work just as well). This will keep your filament dry & free from any dust or dirt particles & moisture.
