We break down the pros and cons of the various types of 3D printing materials, from PETG to TPU, to help you figure out which filament is best for your prints.

He’s designed a simple filament holder which mounts on top of an HX711 load cell, which is in turn connected to the Raspberry Pi running OctoPrint over SPI.

Enrico takes us through his solution to ensure that he always knows how much filament is left on his roll. An Arduino and a load cell combined with some ingenious code are all that is needed.
