Is PETG safe to breathe?
Yes PETG and other nylon filaments cause eye and respiratory tract irritation due to emitting high rates of caprolactam (which is a harmful volatile organic compound)..
How do you dry a filament PETG?
Probably the easiest and most common way of drying filament is throwing it in the oven. Just set the temperature to right below the glass transition temperature of the plastic, and leave it in there for 4-6 hours for the moisture to cook out.
What temperature do you dry PETG at?

Is PETG good for outdoor use?
PETG and ASA are filaments for outdoor use PETG and ASA are 3D printing materials for outdoor use and durable (hold over time). Both filaments are insensitive to changing temperatures and UV rays. They are perfect to use in extreme conditions without deforming shape or appearance.
Is PETG stronger than PLA?
PLA is slightly easier to 3D Print than PETG. This is due to PLA being more forgiving when it comes to settings. … Both are user friendly, however PETG is more durable, stronger and is impact resistant. Technically, you don’t need a heated bed to print both materials.
Is PETG moisture sensitive?
PETG is hygroscopic, which means it will actively absorb moisture from the air. For this reason, PETG plastic should be stored in a cool, dry place, and dried if exposed to humid air for too long.
How do you know if your PETG is wet?
If it’s really wet filament you’ll even hear hisses and pops and it’s extruding.
Do I need to dry PETG?
If you have nylon, polycarbonate, TPU, TPE, or PETG and the spool has been sitting out for more than a day or so, then you likely need to dry it. PLA and ABS are also susceptible, but it takes quite a bit longer for them to absorb enough water to cause major issues.
Does PETG need fan?
The Fan: essentially if you want the strongest possible print, print with no fan. The higher PETG filament temperature will aid super-strong layer adhesion. The molten PETG will stick to the previous layer ridiculously well. But if you need better detail, and no stringing, you really need to use 100% PETG cooling fan.
Is PETG easy to sand?
Coating PETG 3D Printer Filament It sands really easily and gives your parts a glossy finish right off the bat if you don’t intend on sanding it further.
Is PETG safe to drink from?
And PETG is considered a food-safe plastic, but you’ll want to take other factors into account before using it in contact with food. PETG isn’t perfect, of course. It is more flexible than either ABS or PLA, which may be a problem for some applications.
Is PETG weather resistant?
But in the same spirit, PETG is a much more “friendly” plastic than some others. … Also, PETG and copolyesters themselves are UV and weather resistant, so the parts are going to stay strong and usable outside, but the color might fade after a while in the sun.
Is PETG filament toxic?
PETG is the safest 3D printing filament available today. The fumes produced from pure and uncontaminated PETG are harmless. It’s made of the same contents found in PET, with the addition of glycol. PETG has been threatening to overtake other filaments in popularity because it is so safe.
Does PETG go bad?
PETG – Polyethylene Terephthalate Glycol-modified Even when leaving PETG out in the open consistently exposed to humidity, PETG can still be usable up to about a year. However, it’s always best to store it in an airtight container with a desiccant to keep it bone dry.
What is PETG filament good for?
PETG is the perfect filament to combine strength and ductility, which is why it’s used in so many mechanical parts and robotics. It has great chemical resistance with good water, acidic and alkalic resistance. PETG is also makes a great material for artistic prints like bracelet, rings, collars etc..
How do you remove moisture from a PETG?
On Matter Hackers, they give a very reliable way to dry filament:Preheat your oven to 160-180°F (or 70-80°C).Place spool in oven for 4-6 hours.Remove and place in an airtight container, preferably with desiccant. 5-gallon buckets with airtight lids from local hardware stores work very well for filament storage.
What makes PETG brittle?
Hydrolysis of PETG causes brittleness as the polymer breaks down when processed with significant moisture content. As does excess heat.
