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 ...
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 often being confused with the less common 3 mm. [3] Filament consists of one ...
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 ...
Computer-aided design (CAD) model used for 3D printing. The manual modeling process of preparing geometric data for 3D computer graphics is similar to plastic arts such as sculpting. 3D scanning is a process of collecting digital data on the shape and appearance of a real object, creating a digital model based on it.
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.
A standard Hollywood movie averages about five 2,000-foot reels in length. The "reel" was established as a standard measurement because of considerations in printing motion picture film at a film laboratory, for shipping (especially the film case sizes) and for the size of the physical film magazine attached to the motion picture projector.
Countdown on the head leader of a film reel. A film leader is a length of film attached to the head or tail of a film to assist in threading a projector or telecine.A leader attached to the beginning of a reel is sometimes known as a head leader, or simply head, and a leader attached to the end of a reel known as a tail leader or foot leader, or simply tail or foot.
De Forest Audion tube from 1908, the first triode. The flat plate is visible on the top, with the zigzag wire grid under it. The filament was originally present under the grid but was burnt out. Lieben-Reisz tube, another primitive triode developed the same time as the Audion by Robert v. Lieben
