What to consider when buying the best 3D printer filaments
Using one colored pencil to draw gets boring after a while, and you may need a different color to make a project shine. The same goes for 3D printer filament—sure, you could stick with one spool in one color, but just imagine what you can do with different spools of varying strength, materials, and diameters. One general note: you should keep your 3D printer in a well-ventilated area, as it can accumulate fumes that harm your health with too much exposure. Here is what else you should know before buying 3D printer filament:
Filament strength
If you’re doing a project that requires strength—like hooks and anything that will be used to bear weight—look for a filament with high tensile strength. Generally, polycarbonate, nylon, TPU, and composite filament are great choices if you’re looking for something strong. How it was printed will also affect strength, so correctly set the infill percentage in your 3D printer.
Filament material
Filament comes in all kinds of materials. There’s resin filament, stainless steel-filled PLA, wood filament, glitter, carbon fiber, and conducive filament. You’re most likely going to use plastic to 3D print. There are five kinds of plastic filament:
- Polylactic Acid (PLA): a recyclable, natural thermoplastic polyester derived from renewable resources, such as corn starch or sugar cane.
- PLA+: An augmented version of PLA with additives to make it stronger and tougher than PLA. It has better layer-to-layer adhesion compared to PLA.
- Acrylonitrile butadiene styrene (ABS): The most common filament in 3D printing. Strong and resilient, it is made of three monomers: acrylonitrile, butadiene, and styrene. It has a high heat tolerance.
- Thermoplastic polyurethane (TPU): Valued for its flexibility, resilience, durability, and elasticity.
- Polyethylene terephthalate glycol (PETG): a co-polyester that’s durable and easy to use. Good for projects that need to be clear, thanks to its glass-like properties. It has the rigidity of ABS but is easy to print like PLA.
Diameter
1.75-millimeter filament is the most popular size, while 3-millimeter filament is more durable and less likely to jam. The 1.75mm filament gives more precision and control, prints faster, and is less like to ooze. The 3mm filament is great for printers with larger nozzles, is more rigid and makes flexible plastics easier to print, has a higher bending resistance (making it less likely to jam), and works best with professional or industrial 3D printers.
Simply use the filament size that your 3D printer manufacturer recommends. Otherwise, your print could have small holes, missing sections, too much filament in places, and just won’t look as good as it should.
FAQs
3D printer filament can cost between $15-$30 depending on what it’s made of and its size.
PLA has a low heat resistance of can’t be used for high-temperature projects. It has a lower tensile strength than other materials like ABS and PETG. PLA is great if you need to test print or your project doesn’t need to be strong.
The quality of your filament will affect the quality of your prints. Filament with a low tolerance (aka, it’s not consistent along the length of the spool) will affect delivery, yielding a wonky final product. The bottom line is, it’s worth investing in the good stuff.
It depends! Each kind of filament has a different shelf life, and exposure to moisture can shorten its lifespan. If stored properly, the filament can last for years; that turns into months when left out in the open in your damp basement.
