3D printing filament is the thermoplastic feedstock for fused filament fabrication 3D printers. There are many types of filament available with different properties.{{Cite news |url=http://3dinsider.com/3d-printing-materials/ |title=16 Types of 3D Printer Filaments |date=2017-03-09|work=3D Insider |access-date=2017-12-12 |language=en-US|archive-date=2017-12-12 |archive-url=https://web.archive.org/web/20171212190126/http://3dinsider.com/3d-printing-materials/ |url-status=live}}

Filament consists of one continuous slender plastic thread spooled into a reel.{{Cite web|url=https://www.raise3d.com/academy/what-is-3d-printer-filament/|title=What is 3D Printer Filament?|access-date=2022-09-12|archive-date=2022-08-23|archive-url=https://web.archive.org/web/20220823145325/https://www.raise3d.com/academy/what-is-3d-printer-filament/|url-status=live}}
Production

File:3D Printing Materials (16837486456).jpg
3D printing filament is created using a process of heating, extruding and cooling plastic to transform nurdles into the finished product. However, unlike a 3D printer, the filament is pulled rather than pushed through the nozzle to create the filament. The diameter of the filament is defined by the process that takes place after the plastic has been heated rather than the diameter of the extruder nozzle. A different force and speed is applied to the filament as it is pulled out of the extruder to define the width of the filament, most commonly 1.75 mm or 2.85 mm diameter.{{Cite web|url=http://makezine.com/2015/02/11/how-it-is-made-3d-printing-filament/|title=How It Is Made: 3D Printing Filament {{!}} Make|date=2015-02-11|website=Make: DIY Projects and Ideas for Makers|access-date=2017-04-20|archive-date=2017-04-22|archive-url=https://web.archive.org/web/20170422140406/http://makezine.com/2015/02/11/how-it-is-made-3d-printing-filament/|url-status=live}}{{Cite web |url=https://www.filaments.directory/en/blog/2018/08/29/how-are-filaments-made |title=HOW ARE FILAMENTS MADE |access-date=2018-11-07 |archive-date=2018-11-07 |archive-url=https://web.archive.org/web/20181107145332/https://www.filaments.directory/en/blog/2018/08/29/how-are-filaments-made |url-status=dead}}
The plastic nurdles are always white or clear. Pigments or other additives are added to the material before it is melted to create coloured filament or filament with special properties, e.g. increased strength or magnetic properties. Before the filament is extruded the nurdles are heated to 80 °C to dry it and reduce water content. The nurdles must be dried as many thermoplastics are hygroscopic and extrusion of damp plastic causes dimensional flaws (this is also the case when the finished filament is being printed{{Cite web |url=https://www.filaments.directory/en/blog/2016/09/15/what-effect-does-humidity-have-on-your-filament |title=What Effect Does Humidity Have On Your Filament? |access-date=2018-11-07 |archive-date=2018-11-07 |archive-url=https://web.archive.org/web/20181107145342/https://www.filaments.directory/en/blog/2016/09/15/what-effect-does-humidity-have-on-your-filament |url-status=live }}). From there the nurdles are fed into a single screw extruder where it is heated and extruded into a filament. The diameter is often measured by a laser beam(not melting) as part of a quality control mechanism to ensure correct diameter of the filament. The filament is then fed through a warm water tank which cools the filament which gives the filament its round shape. The filament is then fed through a cold water tank to cool it to room temperature. It is then wound onto a spool to create the finished product.
=DIY filament production=
DIY filament production machines use the same method as FDM 3D printers of pushing the filament through the extruder to create the correct diameter filament. There are several DIY filament machines available as both open source plans and commercially available machines.
A food dehydrator can be used to remove water from hygroscopic materials at above 70 °C.{{cite web |title=Can you 3D Print with Trimmer Line?! - YouTube |url=https://www.youtube.com/watch?v=XsrkFIuQEZM |website=YouTube | date=14 November 2020 |access-date=2022-09-12 |archive-date=2022-08-24 |archive-url=https://web.archive.org/web/20220824200058/https://www.youtube.com/watch?v=XsrkFIuQEZM |url-status=live }}
Usage
{{main|Fused deposition modeling}}
The process of transforming 3D printing filament into a 3D model
- The filament is fed into the FDM 3D printer.
- The thermoplastic is heated past its glass transition temperature inside the hotend.
- The filament is extruded and deposited by an extrusion head onto a build platform where it cools.
- The process is continuous, building up layers to create the model.
