  2. Lyman filament extruder - Wikipedia

    en.wikipedia.org/wiki/Lyman_filament_extruder

    The use of DIY filament extruders like the Lyman can significantly reduce the cost of printing with 3-D printers. [2] The Lyman filament extruder was designed to handle pellets, but can also be used to make filament from other sources of plastic such as post-consumer waste like other RecycleBots. Producing plastic filament from recycled plastic ...

  3. Extruder (3D printing) - Wikipedia

    en.wikipedia.org/wiki/Extruder_(3D_printing)

    A Bowden extruder is a type of extruder that pushes filament through a long and flexible PTFE (Teflon) tube to the hot end. [1] An alternative type of extruder which is also widely used in filament 3D printers is the direct-drive extruder , which sits closer to the extruder hot end.

  4. Recyclebot - Wikipedia

    en.wikipedia.org/wiki/Recyclebot

    A recyclebot (or RecycleBot) is an open-source hardware device for converting waste plastic into filament for open-source 3D printers like the RepRap. [1] Making DIY 3D printer filament at home is both less costly and better for the environment than purchasing conventional 3D printer filament.

  5. 3D printing filament - Wikipedia

    en.wikipedia.org/wiki/3D_printing_filament

    3D printing filament in different colours with models created using the filament. 3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers. There are many types of filament available with different properties. [1] Filament comes in a range of diameters, most commonly 1.75 mm and 2.85 mm, [2] with the latter ...

  6. Fused filament fabrication - Wikipedia

    en.wikipedia.org/wiki/Fused_filament_fabrication

    Fused filament fabrication (FFF), also known as fused deposition modeling (with the trademarked acronym FDM), or filament freeform fabrication, is a 3D printing process that uses a continuous filament of a thermoplastic material. [1] Filament is fed from a large spool through a moving, heated printer extruder head, and is deposited on the ...

  7. 3D printing processes - Wikipedia

    en.wikipedia.org/wiki/3D_printing_processes

    A filament of thermoplastic or other low melting point material or mixture is fed into an extrusion nozzle head (3D printer extruder), where the filament is heated to its melting temperature and extruded onto a build table. More recently, fused pellet deposition (or fused particle deposition) has been developed, where particles or pellets of ...

  8. 3D printing - Wikipedia

    en.wikipedia.org/wiki/3D_printing

    3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.

  9. Plastic extrusion - Wikipedia

    en.wikipedia.org/wiki/Plastic_extrusion

    Plastic extruder cut in half to show the components At the front of the barrel, the molten plastic leaves the screw and travels through a screen pack to remove any contaminants in the melt. The screens are reinforced by a breaker plate (a thick metal puck with many holes drilled through it) since the pressure at this point can exceed 34 MPa ...
