3D Printer Filament FAQs

1. What is 3d printer filament made of ?

Most 3d printer filaments are made of thermoplastic. They can be soft when heating above the glass transition temperature. such as PLA, ABS, Petg and so on. The other is composite material which is designed to get more function. It includes wood PLA, PC/ABS, carbon fiber filament and so on.


2. How long does 3d printer filament last ?

It varies from materials and filament diameter. Due to the density being different, the length is also different, you can refer to 1kg PLA filament length here.


3. How to store 3D printer filament?

3D printing filament are highly hygroscopic, so it is vital to prevent water absorption. Also, particles of dust or metal contaminants deposited on the filaments deteriorate printing quality. So, places where you should store 3D printer filament and some corresponding tips are the following:


4. How to make a 3D printer filament?

To make DIY filament for 3D printing, you will need a filament extruder, heavy-duty scissors, a rubber mallet, and failed prints or bulk plastic pellets. The sequence of steps for making 3D printer filament is the following:


5. How to dry 3D printer filament?

In case you notice that your 3D printer filament’s surfaces are “fuzzy” and the printing quality is poor, you need to dry your material. You can do it in the following ways:


6. Why does my 3D printer filament keep breaking?

In case your printing material snapped, it is likely because it has got brittle. The potential reasons are the following:


7. How expensive is 3D printer filament?

Prices for printing material depend on the printing method, the type of filament, its quality, manufacturer, and other nuances. 

For example, regular 3D printing filaments for fused filament fabrication (FFF) like PLA or PETG may cost somewhere between $20 and $50 per kilogram. Engineering or support filaments may be priced from $60 to as high as $120 per kilogram. 

As for other printing materials, entry-level SLA resins are about $50 per liter, while more professional materials may be priced as high as $400 per liter.  SLS powder’s typical cost may fall somewhere between $100 to $200 per kilogram.


8. Which is better, resin 3D printer or filament?

It is better to compare the printing quality of filament and resin 3D printers in order to clarify this question. In most cases, 3D printers that use filaments as the primary material can produce affordable, strong, large-sized pieces. 

At the same time, ones that employ resins can fabricate well-detailed parts. It is because they are based on the more accurate printing method. So, there is no one answer, but it is likely that both printers have a chance to suit your particular purposes well.


9. How to take filament out of a 3D printer?

Perhaps you are struggling with a filament stuck in the hot end, or pulling out the filament requires excessive force. The steps you should follow to take your filament out accurately are: 


10. What 3D printer filament is food safe?

In case you need non-toxic printing materials for your children to play with or store food in, consider the following filaments: 

You should take precautionary measures while dishwashing your plastic parts. PET, nylon, and PLA soften and distort at temperatures above 60–70 °C. Also, none of the printed parts can sustain baking in the oven, while exposure to UV light (or sunlight), may release chemical compounds from the plastic.


11. How to put filament in a 3D printer?

The process of loading the replacement filament in your 3D printer is similar to taking it out, and you can do it by following these steps:


12. What 3D printer filament should I use?

The choice of an appropriate printing material will depend on your purposes mostly. Let’s review several categories of 3D printer filaments for different applications:


13. What 3D printer filament is flexible?

Flexible printing materials are ones that have good elasticity. Commonly, such filaments are made of Thermoplastic Elastomers (TPE) – a blend of hard plastic and rubber. 

The most widespread type of TPE is Thermoplastic Polyurethane (TPU). Thermoplastic co-polyester (TPC) and Thermoplastic Polyamide (TPA) are two other elastomers. Polypropylene (PP) and soft PLA types may also be considered flexible to a certain extent.


14. How to recycle 3D printer filament?

The best way for your plastic scrap and filament leftover disposal – is recycling. You may want to hand it over to a recycling facility. Alternatively, you can handle it yourself.

The latter will require you to purchase a 3D filament recycler. Then, you simply need to sort your scrap by type and color and break it into smaller pieces (unless your recycling unit has a shredder). Then, you can simply melt filament and plastic leftovers and force them through a recycler’s opening. Then, printing materials are automatically extruded, cooled down, and coiled onto a reel.


15. What filament should I use to print 3D printer parts?

The answer to this question will depend on the parts’ desired properties. Some of the different filaments’ characteristics are the following:


16. How to check 3D printer filament properties?

The most simple way to quickly check a particular filament’s properties is to examine its package. Manufacturers typically indicate vital info right on the wrapping, which may include resistance, melting point, tips for printing, etc. Alternatively, you may call and consult a manufacturer’s support team for detailed info. Even the same materials produced by different brands may have differences in their properties. 

Also, you may be advised to take a look at tables of different filaments’ characteristics, like the one below.


17. What is PLA filament for a 3D printer?

Polylactic Acid (PLA) filament is one of the most popular materials for fused deposition modeling (FDM) printing. It is a thermoplastic polymer that is produced from renewable resources only. As such, polylactic acid is generated from cornstarch, potato starch, tapioca roots, sugarcane, and other biomaterials. 

PLA filament is an environment-friendly, low-toxic printing material. It is easy to use, but it still offers competitive properties, including a low melting point, good durability, and moderate flexibility. It can be post-processed using simple methods and is offered in a variety of colors.
