in 3D printing are very common and are due to a set of factors that I am going to list and develop below.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to avoid threads in 3D printing<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If your 3D printer leaves many threads in the print it is because you may have <strong>moisture in the filaments<\/strong>, the configurations of <strong>shrinkage and temperature <\/strong>they may be wrong.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, other factors such as having <strong>the dirty mouthpiece and the poorly leveled bed<\/strong> They can favor the formation of threads in your prints.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>To avoid threads in 3D printing you must:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Activate and configure retractions<\/strong> (in treatment).<\/li>\n\n\n\n<li><strong>Activate Combed Mode<\/strong> (in treatment).<\/li>\n\n\n\n<li><strong>Set up<\/strong> <strong>travel speed<\/strong> (in treatment).<\/li>\n\n\n\n<li><strong>Activate Cooling<\/strong> (in treatment)<\/li>\n\n\n\n<li><strong>Set Print Speed<\/strong> (in treatment)<\/li>\n\n\n\n<li><strong>Choosing the optimal temperature for your filament<\/strong> (in treatment).<\/li>\n\n\n\n<li><strong>Remove moisture from the filaments<\/strong>.<\/li>\n\n\n\n<li><strong>Clean the extruder nozzle.<\/strong><\/li>\n\n\n\n<li><strong>Correctly level the print bed<\/strong>.<\/li>\n\n\n\n<li><strong>Check that the bowden tube couplings are not broken<\/strong>.<\/li>\n\n\n\n<li><strong>Lubricate the bowden tube<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading has-background\" style=\"background-color:#d5e8f070\">Activate and configure retraction settings<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Something very important is to have the retraction settings activated in your favorite Slicer<\/strong>, (in my case it is Cura).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These settings will determine how far and how fast the filament exiting the nozzle will be &quot;retracted&quot; before the extruder moves to another spot on the print bed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is important because if it is not activated or set correctly, the nozzle will continue to lose filament when moving between the walls of the print.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is shrinkage in a 3D printer?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Normally the extruder&#039;s Nema motor is in charge of pushing the filament through the bowden tube, which passes through the hot nozzle while the extruder carriage moves, forming the walls of the print.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Retraction in a 3D printer is the movement of the extruder that instead of pushing &quot;retracts the filament back&quot; in order to release the pressure of the filament in the print nozzle.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the moment that the nozzle must be moved from one point to another, the extruder must stop pushing the filament and retract it back to prevent the filament from continuing to ooze out of the nozzle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Stopping pushing filament and retracting it should release pressure in the nozzle, thus preventing strings from forming when moving between two points.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to enable and configure retraction in Cura<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In Cura print settings <strong>go to the \u201cDisplacement\u201d tab<\/strong> and select <strong>&quot;Enable retraction&quot;<\/strong>.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"495\" height=\"765\" src=\"https:\/\/impresion3d.website\/wp-content\/uploads\/2023\/01\/Hilos-en-impresion-3d-y-como-evitarlos-Habilitar-retraccion.webp\" alt=\"Threads in 3D printing - Enable retraction\" class=\"wp-image-3517\"\/><figcaption class=\"wp-element-caption\">Enable retraction in Cura<\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">By activating \u201cenable retraction\u201d <strong>more options will appear like \u201cRetract Distance\u201d and \u201cRetract Speed\u201d<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These options will allow you to set how fast and how far the filament will retract before the extruder carriage moves to another point.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The default settings in cura can vary depending on the 3D printer you have, but in the latest versions of Cura the default settings are pretty spot on. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The default retraction settings in Cura for an Ender 3 are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Retraction Distance: 5.0mm<\/li>\n\n\n\n<li>Retraction speed: 45.0mm\/s<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"495\" height=\"765\" src=\"https:\/\/impresion3d.website\/wp-content\/uploads\/2023\/01\/Hilos-en-impresion-3d-y-como-evitarlos-distancia-velocidad-de-retraccion.webp\" alt=\"Threads in 3D printing - retraction distance and speed\" class=\"wp-image-3516\"\/><figcaption class=\"wp-element-caption\">Default retraction settings in Cura for an Ender 3<\/figcaption><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\"><strong>I also recommend doing shrink tests to get the best settings for your printer.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The important thing when doing a retraction test is not to modify multiple values at the same time.

Perhaps during the first coat you have noticed that a ball of molten plastic stuck to the nozzle, has this ever happened to you?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That little plastic ball will move back and forth around the nozzle, sometimes leaving strings in the print (especially with Petg filament) and other times getting stuck to one of the outer walls of your model.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I know that many people do not give importance to the cleanliness of the mouthpiece, but believe me, it does. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And I think so so that I even have <a href=\"https:\/\/impresion3d.website\/en\/how-to-clean-the-nozzle-of-the-3d-printer\/\">a post on all the ways to clean a nozzle<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I personally believe that the best way to keep a clean mouthpiece is not to let it get dirty, that is, <strong>cleaning before and after using the printer<\/strong>.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"445\" src=\"https:\/\/impresion3d.website\/wp-content\/uploads\/2023\/04\/Limpiar-boquilla-impresora-3d.webp\" alt=\"\" class=\"wp-image-4729\"\/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\"><strong>As easy as taking a small cloth or paper napkin (being very careful not to burn yourself) and cleaning the nozzle before and after printing your model.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I know it doesn&#039;t sound like much, but believe me having a clean printer nozzle can make all the difference.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-background\" style=\"background-color:#d5e8f070\">Correctly level the print bed<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For some, leveling the print bed can be easy, but for others it can be a little more difficult, since they do not fully understand how far the nozzle should be from the build plate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The reason I put this item on the list is because <strong>a nozzle that is too close can cause excess plastic to be deposited<\/strong> on the print bed, as if it were a burr that comes out in the first layer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If the nozzle is even closer and the speed of the first layer is slow, <strong>it can happen that this filament begins to &quot;escape&quot;

Mechanical (own of the printer), Software (own of the laminator) and those of the environment (Humidity in the filaments).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So there is not just one reason why the threads occur, but rather <strong>there are several<\/strong>, and range from laminator adjustments to printer maintenance and proper filament storage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While not all printers are the same (some with bowden tube and some with direct extrusion) <strong>the tests that I have mentioned in this publication are suitable for all of them<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>temperature tower<\/li>\n\n\n\n<li>Tower for retraction distance.<\/li>\n\n\n\n<li>Tower for Retraction Speed.<\/li>\n\n\n\n<li>Test for retraction test<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">I leave as a summary a list with all the problems and solutions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Problem List:<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li>The threads in 3D printing are formed due to a <strong>printing temperature too high<\/strong>.<\/li>\n\n\n\n<li>The <strong>incorrect retractions<\/strong> they can favor the appearance of threads in 3D printing.<\/li>\n\n\n\n<li> <strong>Incorrect settings in Cura<\/strong>, such as cooling and speed can generate threads in the prints.<\/li>\n\n\n\n<li>The <strong>Moisture absorbed by the filaments can generate threads<\/strong> and other printing problems.<\/li>\n\n\n\n<li>The <strong>dirty nozzles<\/strong> they gather molten filament that breaks off and forms threads in 3D printing.<\/li>\n\n\n\n<li>A <strong>nozzle too close to the bed<\/strong> Printing can collect molten filament in the nozzle and form threads.<\/li>\n\n\n\n<li><strong>Bowden tube can be detached<\/strong> or slipping off pneumatic connectors causing problems, including Wires.<\/li>\n\n\n\n<li>The part of the Bowden tube that rests on the mouthpiece <strong>it can burn and cause problems<\/strong>.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">solution list <strong>in order of importance:<\/strong><\/h3>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>1- Humidity<\/strong>: <\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Remove Moisture From Your Filaments: If your 3D printer is leaving strings and your filament is not brand new, then the first thing you should do is dry your filament and find a way to store it so it doesn&#039;t absorb any more moisture.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>2- Temperature: <\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Find the perfect temperature: You should not follow any other steps until you know what the right temperature is for the type of filament you are using. <strong>Print a temperature tower<\/strong> and choose the best one to always use with that filament.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>3- Level the bed:<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Look for perfection: No matter what you do, if your print bed is not perfectly level you will not get very far, the success of all your prints depends on this step.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>4- Clean the Nozzle:<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Clean the Nozzle before and after printing: It is very common to forget about the nozzle, everyone always worries about cleaning the print bed to have a better adhesion, but they forget about the nozzle. <\/p>\n\n\n\n<h4
