A large majority of 3D printing plastics absorb moisture from the surrounding air which can significantly impact the quality of your 3D printsThese plastics are known as hygroscopic.
After the filament dryer method the food dehydration technique is the secondbest option for drying PETG filament provided that you own a food dehydratorIf you already have a food dehydrator that isnt of much use you can avoid buying a filament dryer because both methods are quite similar.
As a general rule wet filaments have less strength so they break easilyTheir impact resistance will decrease because the H2O molecules weaken the polymer bonds and lower their resistance forcesSo if your final part should withstand force or torque your PETG filaments need to be dried.
As the filament absorbs more moisture all the bubbling cracking and extruder sounds become more visibleAs the absorbed liquid water goes into the hot end it warms up and becomes steam causing extruder noises and filament bubblesAs the filaments absorb more water they make more strings.
As the filament is extruded moisture absorbed in the plastic will rapidly expand boil and rupture forming bubbles in the extruded plasticThese bubbles can have a significant impact on the surface quality layer adhesion and mechanical performance of your 3D printed parts.
Depending on the amount of absorbed water humidity can cause different problems at different levelsThe least problem you can face is to have more stringing around edges and cornersSurface quality may fall and the smooth areas become roughHowever a little moisture won’t create bubbles and popping sounds and mechanical property changes will be minor.
3d insider is supported and earns money with clicks sales commissions and other waysMointure is one of the most dangerous enemies when you are dealing with plastic filaments for 3D printingDo not keep your moisture filaments free can result in them breaking prematurely your impressions get.
How to dry pla filament in ovenDrying filament in toaster ovenAs we have seen in the last section a metal must be heated to extreme temperatures before it emits a useful quantity of visible lightMost metals will melt before reaching these extreme.
Feb 15 2022 The best way to dry PETG filament is by putting it in a dehydrator or a conventional ovenYou can set the temperature of your dehydrator or conventional oven to 149 degrees Fahrenheit 65 degrees CelsiusThe PETG filament will be ready to use after six to eight hours of drying.
Filaments are generally dried in a convection oven at 70 o C to 90 o C depending on the type of material to be driedIt is important to understand which material you are drying before setting the temperature.
For drying PETG set your oven to 149176F and its timer to six hoursThe filament might dry faster but because the oven doesn’t control the moisture level you should let it dry for longer to stay on the safe side.
Gear on the left printed withnbspNylon stored in a dry environment gear on the right printed with wet Nylon exposed to high humidity.
However if the moisture level is low It may only affect the printing quality by stringing oozing and rough edgesFor example if you live in a place with a relative humidity lower than 30 and you put your PETG filament spools in a room you may only see more stringing without extra bubbles or a noisy nozzleSo low humidity won’t affect the printing quality that much.
In theory every polymer absorbs moisture at some levelsSome polymer filaments tend to absorb water and they are called hydrophilic polymersHydrophobic materials are the oppositeHowever filament materials like PVA TPU and especially Nylon have more tendency to absorb water and unfortunately ruin your piece.
Jan 28 2020nbsp0183321Keep your filament in an airtight plastic bagThe best way to dry your PLA filament is to make sure that it does not pick up any moisture in the first place.
Mar 30 2022 PETG drying temperature is 65 degrees celsiusBy taking it and drying PETG in the oven up to 65 degrees Celsius over four hoursYou can use a filament dryer set to make it dry at its highest setting for about 4 hours to 6 at 149 degrees FPlace your PETG filament in a plastic bag and place it in an airtight container or ziploc bag.
Mar 30 2022nbsp018332PETG drying temperature is 65 degrees celsiusBy taking it and drying PETG in the oven up to 65 degrees Celsius over four hoursYou can use a filament dryer set to make it dry at its highest setting for about 4 hours to 6 at 149 degrees FPlace your PETG filament in a plastic bag and place it in an airtight container or ziploc bag.
Not all materials absorb moisture at the same rateWhen left in the open plastics like PLA and ABS may absorb moisture over a matter of weeks or months while more hygroscopic plastics like Nylon and PVA will absorb moisture in a matter of hours or daysOf course this is not the rule and in workspaces with higher humidity or evaporative airconditioning some material types will absorb moisture at a significantly faster rate.
Now let’s talk in more detail.
Oct 25 2018nbsp018332Drying Time 1kg Spool The below drying times are estimates for a 1kg spool when using an accurate drying ovenTimes may vary depending on the filaments water contentPolyCarbonate 75˚C for 8 hours.
PETG should be dried at a temperature of around 65 oC for more than four hoursHowever you can use a temperature of less than 65 oC with more timeThe filament temperature should never go above its glass transition temperature and the glass transition temperature for PETG is 88 o CAfter that the filament will start deforming.
Response PET is highly hygroscopic and absorbs moisture from the atmosphereSmall amounts of moisture will hydrolyze PET in the melt phase reducing molecular weightPET must be dry just prior to processing and amorphous PET requires crystallizing prior to drying so that the particles don’t stick together as they go though glass transition.
Slow drying leaves no gaps in the material preserving its integrityThe filament layers will adhere to one another and to the printing bed ensuring a highquality printThere are several ways to dry PETG filament.
The effectiveness of the filament material is affected during the printing process due to the penetration of moistureHygroscopic filaments such as PETG tend to get wet since they absorb water leaving you with lowquality productsYou need to know your way around drying PETG filament as a 3D printer hobbyist or professional.
The quality of your 3D printing filament plays a significant role in the success of your 3D printsAside from using a reliable brand it is important to handle and store your filament correctly to ensure consistent results through the life of the spool.
We recommend this method for people looking to dry a spool of filament that has absorbed moisture on a onetime basis because the electricity expenses can quickly add up if you use your oven to dry PETG on a daily basis we recommend getting a filament dryer in this situation.
