What are ways to avoid heat creep?

Printer configuration and many settings affect heat creep. Heat creep stopping extrusion doesn't necessarily involve melting the filament too high above the nozzle. All it takes is making the filament too soft. The filament may bend and wad up…

Why do hotends have heat sinks?

I do not understand what purpose the entire heat sink area serves. Obviously, it is to prevent the heat from the heater block from creeping up and melting the filament inside of the heat sink and causing a jam. But what is conducting the heat up?…

Print failure due to heat creep

I have purchased a Creality Ender 3 about a year back. Initially it worked flawlessly even with PETG (at 240 °C) but after some time the prints started to fail. The filament started to expand and clog the hotend. Later I found out that it was due to…

Ender 3 Upgraded to All Metal Hot End -- Heat Creep?

I was having heat creep related hot end clogs leading to skipped layers or plain old air printing (with extruder stepper skipping). Since I'd just received the all metal hot end I ordered a while back (Chinese knock-off, verified 2 mm heat break…

What makes a new nozzle clog before I can finish the print?

I found my Ender 3 was skipping extruder steps a lot, mainly while printing infill (tri-hex at 30%), to the point I saw several layers of infill with spotty extrusion or nothing adhered at all. When I pulled the filament, I had to use pliers to get…

Enclosure with exhaust ventilation for PLA printing

Looking into getting a 3d printer and I'm aware that an enclosure with PLA is unadvisable due to heat creep but was hoping if there was a way to use an enclosure regardless. I'll be in the same room as the printer for extended periods of time if not…

Changing axial fan on CR-10 smart caused temp fluctuation/heat creep

Printer: Creality CR-10 Smart Slicer: Cura My axial fan, which cools the heatsink, broke down. I replaced it with a cheap knock-off fan, as it was the only option available. However, this replacement caused temperature fluctuations that went beyond…
