During the moisture season in certain areas (like China, India, and more), 3D prints start to fail considerably more than anyone would expect.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This is why a dryer can keep your filaments ready-to-print while avoiding stringing, weak parts, and print failures. But what happens when your dryer isn\u2019t working properly? In this article, we\u2019re discussing why your filament dryer isn\u2019t drying and the three possible fixes surrounding it.\u00a0<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">1. Drying Not Heating At All<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The most obvious issue is when the filament dryer doesn\u2019t heat up in the first place. You see, drying relies on sustained temperature, and a dryer that never warms is basically nothing more than a storage box. This is useless for most people because then, you wouldn\u2019t be able to properly get your filaments print-ready, because as soon as you pull it out, in just a matter of a few hours, the moisture is going to take over.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">So, what are some of the reasons why it happens?\u00a0<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Burned-out heating element:<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Firstly, your heating element or filament could be burned out. This includes heating coils or ceramic plates inside the dryer, which degrade over time, especially if you use the dryer often.<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Blown fuse or power failure:<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">An internal fuse can sometimes also blow if there\u2019s a power surge, and it is common in countries with unstable electricity.\u00a0<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Thermal protection lockout:<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Some dryers also have safety cutoffs that can disable heating if there was overheating in the last session.\u00a0<\/span><\/p>\n<p><b>The Fix:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">First, check your power source and plug in your dryer directly into a wall outlet. Sometimes, a power strip cannot provide a stable power supply. There are some filament dryers that come with a manual reset button to restore power after the overheating occurred in the last session.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Lastly, you can also replace its fuse or simply contact your support. If you have a warranty, you might get some help.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2><span style=\"font-weight: 400;\">2. Dryer Heats, But the Filament Isn\u2019t Drying<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">On the contrary, your filament can also start heating when the power is on. To make things interesting, sometimes, it can get warm too and appear to run normally. However, the filament still comes out brittle, stringy, or full of moisture bubbles.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This is quite infuriating since, rather than no heating at all, you are stuck in confusion because your dryer was indeed working but not doing its job properly. Here\u2019s why it happens:<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Poor airflow:<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">The fan inside the dryer circulates warm air, but if it\u2019s broken or blocked, heat won\u2019t go directly to the filament. This is the common cause of the aforementioned issue.<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Full chamber:<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">If you try to fit many filaments in hopes of drying them all, you will see that the air circulation will be limited, leaving many sections of the filaments damp. This gives the illusion that your filament dryer is not working properly.\u00a0<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Bad dryer settings:<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Poor dryer settings will leave filaments undried because each filament requires specific heat and time levels. PLA can degrade if overheated, while nylon needs around 12 hours at 70\u201380 \u00b0C.<\/span><\/p>\n<p><b>The Fix:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">First, you should inspect the fan and listen to the airflow. This is an old yet reliable method because if the fan is weak or silent, you might need to get it replaced. Contact the company\u2019s customer support, or if you know what you\u2019re doing, you can replace it yourself.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Secondly, always use the correct drying profiles for each filament. PLA, PETG, Nylon, and others, all of them would dry at different temperatures compared to each other. Lastly, you should check the chamber cover for cracks or a poor fit. That\u2019s because even if there is a little that allows in the airflow, it can ultimately ruin your entire drying experience.\u00a0<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">3. Dryer Starts But Stops Heating<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Another common problem is when the dryer starts to heat up initially but then shuts down through the cycle. This could become an issue because it leaves your filament partially dried, resulting in your money being lost during the 3D printing process. In some cases, it can be worse because it can cool down mid-cycle, allowing reabsorption.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Here\u2019s why this could happen:<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Faulty Thermostat or Sensor:<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Sometimes, the internal temperature sensor is damaged and can misread or shut off the whole system. This way, <\/span><a href=\"https:\/\/www.chitusystems.com\/products\/filament-dryer\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">the dryer<\/span><\/a><span style=\"font-weight: 400;\"> starts but stops heating in between the processes.<\/span><\/p>\n<ul>\n<li aria-level=\"1\"><b>Unstable household voltage:<\/b><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">In areas with fluctuating electricity supply, dryers will automatically shut off to protect the dryer. But how do you actually fix this issue?<\/span><\/p>\n<p><b>The Fix:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">There are a variety of fixes you can try for these issues. Starting with improving the ventilation. You should always put the dryer in an open space and not against the walls or even inside your enclosure. This way, the excess heat can dissipate and it won\u2019t overheat.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The second fix to try is to reduce the cycle setting. Instead of having the dryer run at the maximum temperature, try moderate heat for longer periods, as it will also reduce the risk of your dryer overheating.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">You can also check the internal sensor that might <a href=\"https:\/\/tuambia.org\/how-to-determine-when-you-need-a-roof-replacement\/\">need replacement<\/a> at this point.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Final Verdict<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A filament dryer that won\u2019t heat or dry properly not only wastes electricity, but it also destroys the print quality and can cost you money as well.
