Aug 24 2017nbsp018332Dessicant gel in a ziplock bag and 3035176C temperature for 24h gives good result longer at lower temperatureMake sure the dessicant is dry usually there are some blue beads that turn white after absorbing humidity sillica gel pouch can be regenerated in microwave 500W for 5 minutes or in oven at 120140176C for half hour.
Drying is important for the stabilization of the quality of every printed object without the influence of storage conditionsThe material may absorb moisture due to storage out of sachet or after a long time of printing when the spool is in the roomSome polymers absorb moisture only on its surface but hygroscopic materials absorb it into the whole structureTherefore the materials were divided into scale 1–5 1 – not necessary to dry 5 – always neededSee column The need to dry in the table.
Drying your filament could be a great solution for improving your print qualityIn this article you will learn how to dry your filament and how to store it after drying.
Feb 10 2022nbsp018332It makes it readily usable for drying up filaments such as the TPU filament wet nylon ABS filament and the PLA filament which prefer a lower drying temperaturePrecautions You Need to Take Before Drying PETG FilamentYou can always dry your wet PETG filament using a convection oven or a dehydrator and get great results.
Here’s how to dry PLA Place your spool of filament in the oven loosening the filament a bit to ensure that the entire outer layer has room to get rid of the moistureLeave the oven door open just a tiny bit to allow steam to leaveBake the filament at 113 186F 45 186C for 6 to 12 hours.
However don8217t worry if you find yourself with filament that has been exposed to moistureIt is still possible to dry them out before using them Also keep in mind that some ways to dry filament can be done in the comfort of your own home without any expensive equipmentBefore we get into how you can dry filament let us recap on why moisture is harmful to plastic and 3D printing.
I have turned unusable PLA into filament that printed well by putting it in a dry oven for a couple of hoursIve used 90 degrees C 194 degrees F which may be too hot as it distorts round filament to be flat sided as the filament softens and relieves stressesPerhaps 70 degrees C 158 degrees F would less deform the filament.
If you have the urge to try different filament types this earlier post will keep you busy for at least a monthThe vendor Thomas used for the carbon fiber filament makes a lot of different exotic blends.
Jun 11 2018nbsp018332The main risk of kitchen ovens is their poor temperature control it may easily get too hot or overshoot the set temp and destroy the filamentSo using the UM glass bed as oven or a dedicated filament dry box or an electronically controlled laboratory oven commonly available in schools universities labs is better.

Most plastics used for 3D printing filament are hygroscopic 8211 meaning that the material absorbs moisture even from the surrounding airKeeping filaments dry isn8217t difficult as you can store them in Ziploc bags with added dehydrating agents like silica gel or to vacuum seal them.
Poorly stored filament humidity or simple accidents can cause water or other liquids to form on your filamentWet filament can produce defective prints so it is advised to keep it dry at all times.
Processing of moist hygroscopic materials at melting temperature causes that the water molecules attack polymer chains which are irreversibly shortenedThe filament must be dried in the device with exact thermoregulation ideally laboratory dryer – before drying of the whole spool put a little piece of filament into the device for the.
Sep 26 2019nbsp018332Tests Ive seen on YouTube indicate the filament will dry significantly fasterJohn 2 Raise3D N2 Duals Bondtech BMGs adjustable table Panucatt SD2224 drivers runout sensor thermal overload protection Firmware 1.
Some filaments PETGPC ABS and Nylon are more hygroscopic than others PLA and to get the best print quality it’s recommended to dry them before starting a new print.
The downside The parts regardless of material tend to shrink a bit in the X and Y axisThey also tend to expand in the Z directionHowever the dimension changes were not that muchThe test parts shrunk by about 5 and grew by 2He didn8217t mention if this was repeatable which is a shame because if it is repeatable it isn8217t a big deal to adjust part dimensions before printingOf course if it isn8217t repeatable it will be difficult to get a particular finished size after the annealing process.
The filament must be dried in the device with exact thermoregulation ideally laboratory dryer – before drying of the whole spool put a little piece of filament into the device for the test of functionalityIn the case that the material becomes softer or looses its original shape lower the temperature of dryingIn the case of loss of transparency use a different device.
The main reason to dry your filament is to have more consistent results during printingMost of the filaments used in 3D printing are hygroscopicThis means that they absorb moisture from the air and loose some of their proprieties.
The spool can’t be put into the environment without a controlled value of relative humidity after dryingThe cooling process must be taken in the desiccator or in the sealing box with the content of silica gelIf the hot spool is placed into the environment with higher humidity the moisture may be absorbed back in about 10 minutes.
The Ultimaker spools are made of a polypropylene copolymer that can soften around 7080°CWhen drying a complete spool it is important to stay below this temperatureAn industrial oven or specific drying equipment such as a Printdry solution should be used since household ovens can heavily fluctuate in temperatureAlternatively it is also possible to place the spool in a cardboard box and use your build plate as the heating source.
To be honest drying my filament was never on the list for meI did not encounter any issues with it in the past but this was probably because I used to finish my filament rolls quicklyNow that I have about 40 rolls of different filaments which are stored without proper care I started to notice a degradation in print quality for older rolls.
To dry TPU you can use a home oven at a temperature of 4560176C for 45 hoursYou can also purchase a filament dryer to dry it and print at the same timeTPU can also be dried inside a DIY dry box with silica gel packets but using a food dehydrator will bring you the best results.
We8217d be interested to see how fine details survive the heating and coolingHowever even if this isn8217t for every part it could be another trick in your arsenal for making 3D printed parts.
Wet filament will produce a poppingcracking sound when extruding almost like the sound of making popcornOozing can also be observed if the extruder motor has stopped but material is still coming from the hot end.
Thomas wanted to try baking some carbon fiber 3D printing filament because the vendor had promised higher strength and rigidity after the parts were annealed in the ovenBeing of a scientific mindset he did some controls and found that annealing parts printed with the carbon fiberbearing filament didn8217t benefit much from the treatmentHowever parts printed with standard PLA became quite a bit stronger and more rigid.
