Plastics
thumb|upright=2|3D Printer materials come in a variety of colors and physical properties.
FFF 3D printers typically accept a filament of a certain diameter.
Some FFF 3D printers are modified to use pellets for ease of using recycled material.10 Tips for Converting a 3D Printer to Pellet Extrusion Make: https://makezine.com/2020/11/25/10-tips-for-converting-a-3d-printer-to-pellet-extrusion/ Make: DIY Projects and Ideas for Makers 30 November 2020 en 25 November 2020
PLA
PLA is a common 3D printing material. It's inexpensive and easy to use, making it a good choice as a starter material for beginners, and a general material for more advanced operators.3D Printer Filaments: Definitions, Applications, and Tips https://www.designreview.byu.edu/collections/3D%20Printer%20Filaments:%20Definitions,%20Applications,%20and%20Tips 6 November 2020
Compared to using ABS, a typical FFF printer using PLA should emit less particles.3D Printer Safety – Environment, Health, and Safety https://aeroastro-ehs.mit.edu/resources/3d-printer-safety/ 6 November 2020
ABS

ABS is cheap and strong but needs the right environment to print well.
Compared to using PLA, a typical FFF printer using ABS should emit more particles.Particles Emitted by Consumer 3D Printers Could Hurt Indoor Air Quality https://www.news.gatech.edu/2019/10/07/particles-emitted-consumer-3d-printers-could-hurt-indoor-air-quality www.news.gatech.edu 6 November 2020 en Ventilation should be used when printing ABS.White Lindsay Materials for 3D Printing – build IT @SDSU Library https://buildit.sdsu.edu/materials-for-3d-printing/ 6 November 2020
HIPS
HIPS is a good starting material due to its ease of use and because it is not expensive.Printing Materials – Innovation Studio https://innovationstudio.mechse.illinois.edu/design-resources/3d-printable-materials/ 6 November 2020
PETG
PETG prints are externally similar to ABS prints despite their different chemical makeup. PETG is less volatile than ABS, remaining stable under a wider range of printing environments.
PETG can't be directly printed on a glass bed. An intermediate material like tape must be used.
Nylon

Nylon 3D prints are known for being somewhat flexible and durable.Closing the Loop On 3D Printing https://www.library.ucsf.edu/news/closing-the-loop-on-3d-printing/ UCSF Library 29 November 2020 30 November 2017Meher Robin Library Guides: 3D Printing at the Library of Engineering and Science: Filament Guide https://guides.lib.purdue.edu/3dprinting/filament guides.lib.purdue.edu 29 November 2020 en
Nylon can also be dyed to produce different color materials.
Nylon can be temperamental and difficult to work with.
Flexible
Flexible filaments are expensive to buy and temperamental to use, but gives prints unique properties, allowing them to deform slightly. These filaments tend to jam, and are best used on direct drive printers.
Ideal Support Materials
thumb|Support material is used to temporarily hold up objects while printing.
PVA
PVA is water soluble, so PVA material melts in water while leaving the primary plastic intact. This makes it ideal for support material when used in a dual extruder or a multi material printer, since supports can be dissolved instead of manually removed.
Composite Materials
Composite materials mix a printable material with a material that typically can't be printed, giving it unique properties, as well as unique challenges.

Resins
SLA printers use liquid resin, instead of filaments.
These resins can usually be colored with dye.Color Kit https://formlabs.com/store/color-kit/ Formlabs 30 November 2020 en-usHow Do I Dye Resin 3D Prints? - Easy To Create Custom Colored Resin https://www.3dprintedminiature.com/how-do-i-dye-resin-3d-prints/ 3D Printed Miniatures for Gaming or Display 30 November 2020 31 January 2020

Material Storage
When possible FFF filaments should be kept in a drybox to avoid contamination of material from humidity and dust.Filament dryboxes and alternative spool holders - not only for MMU2S https://blog.prusaprinters.org/dryboxes-and-alternative-spool-holders-not-only-for-multimaterial-upgrade_30525/ Prusa Printers 6 November 2020 26 July 2019 If this is impractical, a dust filter can also be used on the filament feed.Filament Dust Filter Helps Keep Your Print Quality High https://hackaday.com/2020/09/06/filament-dust-filter-helps-keep-your-print-quality-high/ Hackaday 6 November 2020 6 September 2020
