How do I know if my 3D filament is bad?
Moisture absorbed PLA filament will present with certain features that will tell you immediately that something is wrong. 3D printer damage, weaker 3D prints, and poor 3D print quality are the three main features of an expired PLA filament.
How do you check PLA filaments?
You see that char on the end there. So there’s obviously quite a significant difference with the two
Does 3D printer filament go bad?
Typically, PLA Filament has a shelf life of about 2-3 years. This means you can buy it, store it in a cool, dry, and dark place in its original packaging (to prevent moisture), and still be able to print with it almost 3 years later. Keep in mind that after 2 years the print quality may start to degrade.
How do you know if a filament is enough?
But how do you know whether there is enough? In many cases, it’s obvious. A small 3D print and a near-full spool will clearly work. It’s only when you combine a larger print with a “getting near empty” spool that you begin to have filament anxiety.
How do you revive old filaments?
5 Answers. The easiest way to freshen up filament is hot air, although there are other options. There is an optimal melt processing moisture level for every plastic, typically in the range of 0.1-0.2% water content by weight. But the equilibrium moisture content of most plastics in humid air can be more like 1%.
What do you do with a bad filament?
And heat. Let’s start with moisture. Different filming types are more or less susceptible to
How do you identify filaments?
Try touching the surface of the filament and see whether the filament is dry or smooth, with PLA usually being the smooth filament. ABS has a harsh smell while being heated or printed but PLA emits either little to no smell, or a kind of pleasant sweet smell or like popcorn being heated.
How do I know if my filament has too much moisture?
The easiest way is to extrude some filament and watch it come out of the nozzle. If you see any bubbles, hear any hissing/popping/cracking, or see steam coming off the filament, then it’s definitely wet and needs to be dried out.
How do I know if my filament is too moist?
- Popping or cracking sounds when extruding.
- Severely reduced part strength and layer adhesion.
- Uneven extrusion lines.
- Uncharacteristically severe stringing, blobbing, or oozing.
How long does 3d printing filament last?
On average a standard roll of 1.75mm PLA filament will last approximately 123 hours of printing time. A standard roll of 3.00mm PLA filament will last approximately 141 hours of printing time. To come up with these averages I used a slicer to calculate the filament usage of several models.
How quickly does PLA filament go bad?
ABS filament may expire within a month of humidity exposure, while bio-plastics such as PETG and PLA may last one to two years respectively, without going bad.

How long can PLA sit out?
According to most users, even with 40% humidity, their PLA filament was alright for up to 4 days. The filament might become a bit brittle but overall it is not very risky to leave it out there.
How much filament do I need for a print?
The amount of filament you will need in general
Basically, anything short of a full-blown project. In this case, most 3D prints would not exceed 50 grams of filament (PLA). You can easily get away with keeping 2 or 3 spools of 1KG filament on-hand.
How far does 3D filament go?
According to Rigid Ink, based on PLA having a density of 1.25g/ml a 1KG spool of PLA would measure up at around 335 metres for 1.75mm filament and 125 meters for 2.85mm filament. In feet, 335 metres is 1,099 feet.
Are all PLA filaments the same?
It is mostly the same, with a few slight differences: better surface quality, color, and mechanical properties. Most PLA+ filaments are advertised as being stronger, less brittle, more durable, and better for layer adhesion. Tough PLA is another term used by some manufacturers.
