If you are trying to get clean colors, you have to purge the nozzle (that is, run the extruder until the new color shows up). If you want an artistic fade, you could skip that step–totally up to ...

M ore leaks from Bambu Lab reveal that a new single-nozzle sister to the H2D is coming soon. The H2S was accidentally included in a manual for the cutter module in the Bambu Lab wiki.

Entrepreneurs in Denmark have taken another step towards improving the general usability of 3D printers with the Diamond Hotend, a single 3D extruder unit that can mix and melt three filaments ...

From Wade’s gear extruder to a nozzle made from an acorn nut, having the hotend and extruder as separate devices has become the standard. This week at the Midwest RepRap Festival, E3D unveiled ...

Calibration for the extruder is simple enough. If you command 100mm of extrusion manually, does 100mm of the filament come out of the extruder to go into the hotend?

Print speed also affects quality. Excessive speed causes vibrations and poor layer adhesion. Slowing down in tricky spots ensures proper filament deposition. Achieving the optimal speed settings, ...

The XYZprinting da Vinci Jr. 1.0 A Pro is a moderately priced closed-frame 3D printer with a large build volume and overall good performance, but a potentially balky filament-feeding system.

While other pens have a single extruder nozzle, Scribbler clearly believes that two heads are better than one, and has launched a dual nozzle 3D printing pen called the Duo on Kickstarter.

Instead, I had to move the extruder nozzle—the tip of the extruder assembly that molten filament flows out of—to positions near the four bed adjustment screws and turn them until it was 0.05 ...

3D-printed composite wind blades and aircraft, closer than you think Orbital Composites’ patented coaxial extrusion process is investigated at Airbus subsidiary CTC GmbH Stade and spins off advances ...

It worked--sometimes. Other times the nozzle plugged up, the wafer loader jammed or the platform on which the prototype was formed slammed into the extruder.
