Troubleshooting PLA Jamming in All Metal Hotend

Published on in Category 3DPriting

PLA Jamming happens in any all metal hotend, even with E3D, Prusa Nozzle, Printrbot Metal Hotend, etc,. PLA jamming in all metal hot end is common issue, but this does not happen with PEEK based JHead Hotends. Metal Hotend can print High temperatures filaments without any problem, this includes high temperature filaments like ABS, Nylon, Ninja Flex, etc., Here we try to list down the most command reason for jamming and solutions for the same.


Cleaning blocked extruder nozzle in 3D printers

Published on in Category 3DPriting

Many of you don’t like the nozzle clogs and blocks, We too. Even the smallest contamination can block the 0.4mm nozzle, You can use a 0.4mm or smaller drill bits to clean up the aperture while the hotend is hot. But sometime (many time) the contamination would come back and block the nozzle. That’s very bad especially when your are in the mid of big prints. Nozzle block or clogs can identified via below symptoms, - filament are not extruding uniformly - extrude very thin filament than usual - Or the filament is not at all coming out from nozzle.

Step 1:Insert the PTFE socket into PEEK isolator The dark brown (bigger part) is PEEK isolator and white colour (smaller part) is PTFE socket. Insert the PTFE socket into PEEK isolator as show in the picture and tighten it using the grub screws. Step 2: Seal the Thread using PTFE tape Use PTFE thread seal tape (not in kit) and apply few turns then, screw the nozzle on the heat barrel as show in picture

Inspired by the J Hotend design and reliable usage by the community, aSensar’s hotend derives design ideas from J hotend. Here is the rendering of aSensar hotend. we have eliminated the PTFE lining, used in the J hotend. Just received the aSensar Hotend from the fab, it came very well as we expected Machined parts of aSensar Hotend + Hex key + Ceramic heater cartridge Fully assembled aSensar Hotend Rendering for your comparison
