The best known issues are nozzle clogging and extruder slipping. A well-working extruder can slip when pushing forces are too high in the hotend of the extruder (printing at high speed can be a cause) or when pulling forces are too strong (for example, when the filament gets stuck). Following this reasoning, it seemed reasonable to think that restrictions in the PTFE tubing might cause extrusion problems or, in the very least, losses in the extrusion process.<\/p>\n<p>&nbsp;<\/p>\n<h2>The challenge<\/h2>\n<p>We initially believed that length of the PTFE path, total bend angle and the bend radiuses of the PTFE would greatly affect the friction forces in the tubing, to the point where the extruder would lose efficiency.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p class=\"link-btn-style btn-yellow\"><a href=\"https:\/\/dyzedesign.com\/fr\/2023\/01\/the-adverse-effects-of-ptfe-restrictions\/\" target=\"_blank\" rel=\"noopener\">Read the case study<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dyze Design (2023). &nbsp;
