The Fused Filament Fabrication (FFF) printing process is incredibly adaptable—however, 3D Printer Filament doesn’t work for every plastic. As a result of the tight constraints required to precisely extrude plastic out of a tiny nozzle, traditional plastics originally optimized for injection molding do not print. The plastics that are printable, however, cover a massive range of compositions, print constraints, and material properties. To find the right material, you need to match the requirements of your applications to the properties of the materials you can print with. In this article, we discuss the strengths and weaknesses of a variety of thermoplastics.

In addition to printing thermoplastics, Markforged also adapts the FFF process to print non-plastic materials. In Continuous Filament Fabrication (CFF), an FFF 3D Printer with a specialized second nozzle lays down continuous carbon fiber, fiberglass, or Kevlar® into a part. Atomic Diffusion Additive Manufacturing (ADAM) builds on the existing metal fabrication technology of Metal Injection Molding (MIM), by using an FFF based process to print metal powder encased in a plastic binder. These printed parts are placed in a solvent bath to remove binding material and sintered into fully metallic parts.

Standard thermoplastics

As 3D printing has expanded rapidly, so has the variety of PETG 3D Printer Filaments. Despite this boom, most FFF 3D-printable thermoplastics fit into three categories: basic thermoplastics, niche thermoplastics, and superplastics.

Superplastics: These materials possess all the aspects necessary to thrive in manufacturing environments. PEEK and Ultem are both strong, stiff plastics that have extremely high heat resistance and chemical resistance. Engineers used them heavily in manufacturing before they were 3D printable, and now use Multifunctional 3D Printers to create custom, robust fixtures out of these materials.

Continuous fibers (CFF)

While chopped carbon fibers are remarkable in their ability to augment thermoplastics, continuous fibers can add far more strength to parts. Markforged uses a combination of FFF printing and Continuous Fiber Fabrication (CFF) to lay down long strand fibers in conventionally printed thermoplastic parts. This technology is also extrusion based and prints via a secondary nozzle, but instead of melting the whole PCL 3D Printer Filament, it uses the heat of its nozzle to “iron” down fibers into a thermoplastic layer. Fibers do not melt—instead, they’re captured by the thermoplastic matrix in a similar way that thermoset adhesives like epoxy capture fibers in traditional fiber fabrication methods.

3D printing pen seems to be the buzzword around 3D printing enthusiasts and hobbyists. Be it a child or a professional artist, everyone is eager to have a 3D printing pen. The fact that it brings fun at the workplace, inspires creativity and helps in learning, is making 3D Pens a craze all over the world.

Grown out of a necessity to democratise the 3D printing technology and make it accessible to even the average person, three enthusiastic people worked on creating a device which is not as bulky, costly and techno-centric as a 3D printer. The three inventors built, Peter Dilworth, Maxwell Bogue, and Daniel Cowen of WobbleWorks, Inc their first prototype in 2012 in a makerspace. They invented the first Cordless 3d Printing Pen which they called a 3Doodler. It is said that they had a bad experience with 3D printers and wanted to create a product that was simple & affordable to every hobbyists and artist.

The heating temperature is adjusted as per the material used in the pen. Only a limited number of materials can be used in a 3D Children Smart Pen. The requirement for a material to be used in a 3D printing pen is that it should melt quickly when heated and solidify quickly once it is extruded out of the pen. The user should also note that he should not draw with the 3D pen like a regular pen. The 3D pen should be moved slowly so the figures can be drawn and it holds its shape.
