![]() ![]() Chopped fiber reinforced plastics, on the other hand, utilize industrial grade fibers to improve the material properties of printing thermoplastics. Exotic material filled plastics are most similar to niche plastics, as their secondary materials (coffee, wood, and other materials) alter texture and appearance more than mechanical properties. Adding particles of a stronger material to thermoplastic can alter many material properties (though chemical resistance is still wholly dependent on the plastic).įilled thermoplastics fall into two camps: exotic material filled plastics and chopped fiber reinforced plastics. The concentration of the second material may vary, but it’s still primarily a thermoplastic by composition and material behavior. Engineers used them heavily in manufacturing before they were 3D printable, and now use printers to create custom, robust fixtures out of these materials.Ī filled thermoplastic is a material in which a standard plastic is impregnated with tiny particles of a second material. PEEK and Ultem are both strong, stiff plastics that have extremely high heat resistance and chemical resistance. Superplastics: These materials possess all the aspects necessary to thrive in manufacturing environments. Despite this boom, most FFF 3D-printable thermoplastics fit into three categories: basic thermoplastics, niche thermoplastics, and superplastics. These printed parts are placed in a solvent bath to remove binding material and sintered into fully metallic parts.Īs 3D printing has expanded rapidly, so has the variety of printing filaments. 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. 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. In addition to printing thermoplastics, Markforged also adapts the FFF process to print non-plastic materials. In this article, we discuss the strengths and weaknesses of a variety of thermoplastics. To find the right material, you need to match the requirements of your applications to the properties of the materials you can print with. The plastics that are printable, however, cover a massive range of compositions, print constraints, and material properties. 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 Fused Filament Fabrication (FFF) printing process is incredibly adaptable-however, it doesn’t work for every plastic. Continuous Fibers (Carbon Fiber, Fiberglass, and Kevlar) - Composite materials, ideal for industrial uses.Chopped Fiber Reinforced Plastics - Superplastics, ideal for industrial uses.PEEK/ULTEM - Superplastics, ideal for industrial uses.Polycarbonate - Medium Grade industrial material.(In the same way that changing the ratio of liquids in a drink changes what drink it is.3D printing materials covered in this article: These building blocks change each substance overall. PEKK is a different Poly: Ether-Ketone-Ketone (1 Ether, 2 Ketones). PEEK is a Poly (multiple/blend) of Ether-Ether-Ketone (2 Ethers, 1 Ketone). The different names indicate the quantity/order of Ether and Ketone components. Like all chemicals, PEEK and other PAEK materials consist of specific building blocks of elemental molecules. Yet PEEK is one of the only materials actually used by industry and companies today. All PAEK materials are well known for chemical resistance, high-temperature resistance, and low wear-and-tear. In addition to PEEK, there is PEK, PEKK, and PEKEKK. The PAEK Family PAEK (Polyaryle Ether Ketones) is an entire family of thermoplastics. However, Victrex is now the name of an ICI spin-off company manufacturing PEEK. This UK manufacturer formulated Victrex, known today as PEEK. PEEK (Polyether Ether Ketone) is new substance for industrial 3D-printing, created in 1926 by Imperial Chemical Industries (ICI). Vision Miner company specializes in PEEK and PEI, but let’s look at the differences between each. Filament materials like PEEK, PEI, PAEK, and PEK can be confusing. ![]() High-temperature 3D Printing can be challenging. WHAT are PEEK, PEI, PAEK, and PEKK materials, and what their differences?
