Most 3D printer motion sensors are bulky, slow to trigger, prone to false positives, and have a high detection distance meaning a large amount material is extruded before actually detecting a runout, ...

The Roadrunner motion sensor is based on a magnetic rotary encoder which can detect sub-millimeter movement in the filament for accurate extrusion length measurement, in addition to an IR sensor which ...

Just how tight are the manufacturing tolerances of modern FDM printer filament. Inquiring minds want to know, and when such minds are attached to handy fellows like [Thomas Sanladerer], you end up ...

I keep up with the trends in 3D printing reasonably well. The other day my friend mentioned that filament thickness sensing had been added to the latest version of the Marlin firmware. I had no idea ...

Christopher Robertson has created a new 3D printer filament roller and feeder which offers an all-in-one IR sensor and alarm to detect all filament feeding errors automatically to help stop your ...

Purdue University researchers have developed a patent-pending method to add particles to filament and disperse them evenly through a traditional fused deposition modeling, or FDM, 3D printer, which ...
