Today I want to share my experience with the drying of Tpu material. So the problem with TPU is that it absorbs water from the air very fast, even if you have a dry climate inside your house\/room. Mine is not so dry land but still surface of filament becomes moist after 1-2 days.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Maybe_somebody_knows_how_to_make_it_drier\"><\/span>Maybe somebody knows how to make it drier?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Yes of course there are some desiccant packs for this purpose but they are expensive and hard to find here in Russia. Then I found another solution for this problem.<\/p>\n<p>First, what you need to do &ndash; get an automatic fish tank water drier (see photos below). It has a fan on one side that sucks air through the other side and through the tank with a desiccant inside. So evaporated water from the fish tank will be sucked away as well as air moisture. For this case, I used a special plug for this drier to feed the filament into it.<\/p>\n<p>To do that you need to solder\/weld a new connector on the filaments wire and use it instead of the original plug. Fan speed is adjustable so you can change it during the drying process depending on the wetness of the filament (when the filament was dry, I lowered the fan speed). This system runs almost 5 days non-stop and dried my TPU part completely.<\/p>\n<p><noscript><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-2276\" src=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/How-to-dry-TPU-filament-in-oven.jpg\" alt=\"How to dry TPU filament in oven\" width=\"450\" height=\"408\" srcset=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/How-to-dry-TPU-filament-in-oven.jpg 450w, https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/How-to-dry-TPU-filament-in-oven-300x272.jpg 300w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-2276 lazyload\" src=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/How-to-dry-TPU-filament-in-oven.jpg.webp\" alt=\"How to dry TPU filament in oven\" width=\"450\" height=\"408\" srcset=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/How-to-dry-TPU-filament-in-oven.jpg.webp 450w, https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/How-to-dry-TPU-filament-in-oven-300x272.jpg.webp 300w\" sizes=\"auto, (max-width: 450px) 100vw, 450px\" data-pin-media=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/How-to-dry-TPU-filament-in-oven.jpg\" id=\"mv-trellis-img-8\" data-trellis-processed=\"1\"><\/p>\n<p style=\"text-align: center;\">How To Dry Tpu Filament?<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Drying_TPU_filament_in_the_oven\"><\/span>Drying TPU filament in the oven?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>I know it&rsquo;s the most frequent question people use to ask when they get TPU.<\/p>\n<p>The filament is coming with a high humidity level that is very bad for the quality and will cause problems in 3D printers during the printing process such as:<\/p>\n<p>-Filament grip on hotend nozzle, extruder gear, and motor. &nbsp;Resulting in less extruding efficiency and jamming under the higher temperatures of 200+ degrees Celsius.<\/p>\n<p>-Decrease or lost of adherence between layers (aka pillowing effect).<\/p>\n<p>It was really hard to find proper information about how to dry TPU properly. So I decided to share my experience here! &#128578;<\/p>\n<p>When we talk about drying; we need an oven, aluminum foil some patience. Here you go!<\/p>\n<p>Note 1: For the first few hours, you&rsquo;ll get bubbles between layers. Don&rsquo;t worry about it! It&rsquo;s completely normal and will be gone in the next hour or so.<\/p>\n<p>Note 2: Allow filament to cool down after finishing baking. Do not try to unload before it&rsquo;s 100% cool! You may damage something in the extruder if you do it.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_1_%E2%80%93_Setup\"><\/span>Step 1 &ndash; Setup<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Preheat oven for ~15 minutes at ~100&deg;C (210&deg;F). Yes, I&rsquo;m using a very simple method of preheating the oven with only 15 mins boost time instead of full power for an hour or more as many people do; but I&rsquo;m still able to dry filament properly even it takes a longer time than usual.<\/p>\n<p>Note: &nbsp;If you&rsquo;re using an oven that has metal wire racks inside then use the aluminum foil that is very sticky and thick enough to cover the gap between wires. Wrap filament with aluminum foil tightly, place it in the oven, and start baking! Do not forget about preheating time before starting the actual drying process!<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_2_%E2%80%93_Filament_Baking_Process\"><\/span>Step 2 &ndash; Filament Baking Process<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Bake for ~30-45 minutes at 100&deg;C (210&deg;F). Turn off the oven and let the filament cool down slowly in the oven without opening the door. Note: After turning off my oven, I leave it for ~2 hours because sometimes when we unload filament from a hot oven; it may lost some adherence between layers especially if baked longer than 40 mins or at a high temperature.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Step_3_%E2%80%93_Unloading_from_O_V_E_N_%E2%80%93_Do_not_try_to_unload_filament_immediately_after_turning_off_the_O_V_E_N\"><\/span>Step 3 &ndash; Unloading from O V E N &ndash; Do not try to unload filament immediately after turning off the O V E N!<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Just let it cool down completely inside the baking oven before removing it. &nbsp;Be very gentle when removing the aluminum foil. If you need to save some filament for the next printing session, keep in mind that most of the water is already gone after this step and you just have to store your filament in an airtight container or seal a bag with minimum possible humidity level.<\/p>\n<p>I hope this article helps someone who had problems with the TPU drying process due to high humidity levels when they get it from their favorite fab shop!<\/p>\n<p style=\"text-align: center;\"><noscript><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-2275\" src=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-use-tpu-filament.jpg\" alt=\"how to use tpu filament\" width=\"377\" height=\"332\" srcset=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-use-tpu-filament.jpg 377w, https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-use-tpu-filament-300x264.jpg 300w\" sizes=\"auto, (max-width: 377px) 100vw, 377px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-2275 lazyload\" src=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-use-tpu-filament.jpg.webp\" alt=\"how to use tpu filament\" width=\"377\" height=\"332\" srcset=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-use-tpu-filament.jpg.webp 377w, https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-use-tpu-filament-300x264.jpg.webp 300w\" sizes=\"auto, (max-width: 377px) 100vw, 377px\" data-pin-media=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-use-tpu-filament.jpg\" id=\"mv-trellis-img-9\" data-trellis-processed=\"1\"><\/p>\n<p style=\"text-align: center;\">How To Dry Tpu Filament?<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Drying_filament_in_the_dehydrator\"><\/span>Drying filament in the dehydrator<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The 3D filament is extremely hygroscopic. During the printing process, small amounts of humidity are absorbed by the molten plastic, which can have a negative impact on various properties of finished prints. While this may not be apparent in everyday use, it is often dramatically visible in 3D printed objects that require high tensile strength or other properties related to water absorption.<\/p>\n<p>The best way to mitigate humidity-related problems is by storing the filament in an environment with low relative humidity (RH). Unfortunately, not all filament is stored properly before being sold. This means there might be moisture left inside thus changing its mechanical characteristics even if kept sealed since it was manufactured.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Many_companies_dry_their_filaments_for_weeks_at_elevated_temperatures_prior_to_sale_but_most_filaments_available_to_home_users_do_not_have_this_treatment\"><\/span>Many companies dry their filaments for weeks at elevated temperatures prior to sale, but most filaments available to home users do not have this treatment.<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>In the past, I have seen many methods used by users to dry filament, including heating it in an oven for a couple of hours at 40-60 &#730;C or leaving it out in the sun.<\/p>\n<p>In my case, I bought a dehydrator from [Michael] and got rid of moisture issues arising from time to time with various filaments. After drying you can see a huge difference in color between a dried and a wet filament:<\/p>\n<p>I use my food dehydrator which is almost silent and lets me sleep while doing its job. A quick test showed that keeping 3D printed objects in a low humidity environment can keep them from warping during printing as well.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"TPU_filament_drying_temperature_filament_dry\"><\/span>TPU filament drying temperature (filament dry)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Hi, I have the filament manufacturer recommended the printing temperature for TPU (eSun) to 245&deg;C &ndash; but on my Printrbot + it only has a max temp of 230&deg;C. Any idea how many degrees off is that? Someone told me that TPU starts to decompose under 300&deg;C I&rsquo;m using Simplify3D. Thank you! Best regards, Mikka<\/p>\n<p>The advice your friend gave you is for ABS or PLA which are both prone to warping when printed too hot. As far as the quality of your print goes there&rsquo;s not much difference between 245 and 230 in terms of material properties so if anything I would move down from 245 rather than up from 230 since with each degree C your nozzle gets hotter the risk of damaging your nozzle also goes up.<\/p>\n<p>Even though you are moving away from the recommended filament temperature for this type of filament it is not going to cause any problems with TPU as long as you don&rsquo;t go all the way down to 230&deg;C and no higher than 245&deg;C (which is the maximum that your printer will allow). Just make sure you use a material that was formulated for extrusion temperatures no lower than 245&deg;C. And if you&rsquo;re wondering why I&rsquo;m recommending a different brand considering eSun has been used by almost everyone who prints TPU &ndash; well, there are two main reasons:<\/p>\n<p>1) When printing at higher speeds it can be difficult to keep track of whether or not you&rsquo;re still at the right temperature or if your extrusion is just right or whether it has stopped due to overheating. With eSun that becomes more of a problem since they use a slightly different formulation which works well on normal PLA settings but when trying to print TPU using these settings it would be difficult to get consistent results from one printer to another. So I do not recommend eSun for high-speed prints with this type of filament.<\/p>\n<p>2) The formulation used by eSun can sometimes cause problems when printing flexible filaments since it does not have enough flexibility and elasticity by itself so a 100% infill is required in order to keep the object from splitting while under stress. This is actually something I&rsquo;m going to experiment with next as I have had a few reports of splitting issues from other people printing flexible filaments.<\/p>\n<p style=\"text-align: center;\"><noscript><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-2274\" src=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-print-tpu-filament.jpg\" alt=\"how to print tpu filament\" width=\"454\" height=\"404\" srcset=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-print-tpu-filament.jpg 454w, https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-print-tpu-filament-300x267.jpg 300w\" sizes=\"auto, (max-width: 454px) 100vw, 454px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-2274 lazyload\" src=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-print-tpu-filament.jpg.webp\" alt=\"how to print tpu filament\" width=\"454\" height=\"404\" srcset=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-print-tpu-filament.jpg.webp 454w, https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-print-tpu-filament-300x267.jpg.webp 300w\" sizes=\"auto, (max-width: 454px) 100vw, 454px\" data-pin-media=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/10\/how-to-print-tpu-filament.jpg\" id=\"mv-trellis-img-10\" data-trellis-processed=\"1\"><\/p>\n<p style=\"text-align: center;\">How To Dry Tpu Filament?<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Can_you_dye_Tpu\"><\/span>Can you dye Tpu?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A quick search on the internet will reveal to you that many people have been asking this exact question.<\/p>\n<p>In fact, I found myself wondering the same thing last year but I never ordered any Tpu to give it a try.<\/p>\n<p>It&rsquo;s still not too late however as a couple of days ago a friend who is a 3D printer owner came over and gave me some TPU filament which he didn&rsquo;t need anymore. What should we do with all the colors given to us? Yes, make some dyes out of them!<\/p>\n<p>I cut about 10cm from each spool and boiled them for about 30 minutes with 1 liter of water. Then just let it cool down to room temperature and voila 2 liters of dye are ready to use.<\/p>\n<p>It&rsquo;s very easy to do and the color is deep and brilliant.&nbsp;I used a metal spoon but next time I will probably try with a plastic spoon instead, to avoid getting any black marks from the metal.<\/p>\n<p>The good thing about Tpu dye is that it keeps its color even after washing many times (actually, it&rsquo;s still as new). The bad thing, however, is that if you are using hard water then your colors might be more or less intense depending on its concentration of Calcium Carbonate which some dyes are very sensitive to. Anyway, all you have to do is do some testing at home first until you find the perfect ratio of dye\/water for your water.<\/p>\n<p>Oh, and forgot to tell you but I also did the same with <a href=\"https:\/\/www.amazon.com\/OVERTURE-Filament-Consumables-Polyamide-Dimensional\/dp\/B087R3M9Z2?crid=1DJYSHVG585P4&amp;keywords=nylon+filament&amp;qid=1661427172&amp;sprefix=Nylon+filament%2Caps%2C398&amp;sr=8-1-spons&amp;psc=1&amp;linkCode=ll1&amp;tag=printerpreneur-20%20&amp;linkId=040f79b1e488611b34e7122d97a0d121&amp;language=en_US&amp;ref_=as_li_ss_tl\" target=\"_blank\" rel=\"nofollow\">Nylon filament<\/a> which is a bit more difficult since it doesn&rsquo;t dissolve in boiling water (even after heating up for a couple of hours).

This way it is also easy to change colors or material after import if needed.<\/p>\n<p>Afterward go to &ldquo;Machine&rdquo; -&gt; &ldquo;Printing environment&rdquo;, now your printer should be set up for this job!<\/p>\n<h4><span class=\"ez-toc-section\" id=\"I_decided_now_that_I_want_to_print_my_object_in_two_parts_what_do_I_have_to_do\"><\/span>I decided now that I want to print my object in two parts, what do I have to do?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>At first select, all objects that need different settings in Ultimaker Cura, then right-click on them and choose &ldquo;Split&rdquo;. Now rename each of these parts according to its setting (for example: name one part &ldquo;Left Upper Part&rdquo; and the other one &ldquo;Right Lower Part&rdquo;) and move them together in order to prevent they touch each other, afterward you can use the preview in Ultimaker Cura and hide\/move parts if needed.

You also have to perform some tests in order to find out how many mm\/s are actually needed at the different settings (which depends on your specific setup).<\/p>\n<p>If these numbers are too low, try slowing down before retrying again with higher values since otherwise, the extruder might jam.<\/p>\n<p>Ultimaker Cura 3.3 also allows you to adjust the speed during infill at different speeds in order to prevent material slipping and reduce print artifacts, which is especially critical for flexible materials.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_problems_might_occur_when_printing_TPU\"><\/span>What problems might occur when printing TPU?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>When printing with normal PLA settings, you might get stringing on the object since it slips through the nozzle very fast since it&rsquo;s so flexible. This can be solved by slowing down before retrying again with higher values since otherwise, the extruder might jam.<\/p>\n<p>If this fails too, try increasing flow rate at given percentages (for example from 0.9 to 1.0) until a reliable result is achieved &ndash; but keep in mind that this number might change after a while or even get worse again.<\/p>\n<p>Another possible problem is that the printer might skip\/drop steps which cause visible artifacts on your object (printouts like squares, stripes etc.). If this happens, try to reduce speed before retrying again with higher speeds since printing too fast (without reliable calibration) could cause this problem.<\/p>\n<p><noscript><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-519\" src=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/05\/Pla-Vs-Abs-Vs-Tpu.jpg\" alt=\"Pla Vs Abs Vs Tpu\" width=\"543\" height=\"377\" srcset=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/05\/Pla-Vs-Abs-Vs-Tpu.jpg 543w, https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/05\/Pla-Vs-Abs-Vs-Tpu-300x208.jpg 300w\" sizes=\"auto, (max-width: 543px) 100vw, 543px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-519 lazyload\" src=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/05\/Pla-Vs-Abs-Vs-Tpu.jpg.webp\" alt=\"Pla Vs Abs Vs Tpu\" width=\"543\" height=\"377\" srcset=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/05\/Pla-Vs-Abs-Vs-Tpu.jpg.webp 543w, https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/05\/Pla-Vs-Abs-Vs-Tpu-300x208.jpg.webp 300w\" sizes=\"auto, (max-width: 543px) 100vw, 543px\" data-pin-media=\"https:\/\/printerpreneur.com\/3d\/wp-content\/uploads\/2021\/05\/Pla-Vs-Abs-Vs-Tpu.jpg\" id=\"mv-trellis-img-12\" data-trellis-processed=\"1\"><\/p>\n<p style=\"text-align: center;\">How To Dry Tpu Filament?

It&rsquo;s important that you do not exceed 230 degrees Fahrenheit and also be sure to turn off any fans in your drying chamber. If these steps are followed correctly, then it should take about 1-2 hours for your material to completely dry out.<\/p>\n<p>After this time frame has passed, it will be safe for storage or further processing if desired.
