It is well suited for any applications that require optical transparency or translucence, or as a less durable but cheaper alternative to polycarbonate. It is tough, with decent impact strength and scratch resistance, and can be easily glued using acrylic cement.
Learn more in about nylon in the Capabilities Guide Acrylic OverviewĪcrylic, which is also known by trade names Plexiglass or Luctie, has a chemical composition known as PMMA (Poly Methyl MethAcrylate) plastic. In many of these applications it is used as an economical alternative to metals. Nylon is most commonly found in medical devices, circuit board mounting hardware, electrical insulation, automobile engine compartment components, and aerospace components. It can also warp if there is a large amount of asymmetric material removal during machining, due to internal stresses inherent in the material. Nylon 6/6 will absorb moisture, causing it to swell and lose some dimensional accuracy. Glass-filled nylon is rigid, strong, hard, tough and dimensionally stable. Nylon 6/6 is a good choice for applications in which strong, durable parts are needed at a low cost.
Nylon has a high strength and rigidity that it maintains over a wide temperature range, good electrical insulation, and good chemical and wear resistance. Glass filled nylon is also popular and provides a great CNC machining material to work with. It has relatively high chemical and heat resistance with rigidity necessary to retain its shape and strength to resist deformation under loading conditions. Nylon 6/6 is a strong and durable plastic which can be utilized for a wide variety of applications. Learn more in about ABS in the Capabilities Guide Nylon CNC Machining Overviewįictiv offers Nylon 6/6 and glass-filled nylon. The most common applications of ABS are for pre-injection molding prototypes, make electronics enclosures, household appliances, and even the iconic Lego bricks. This means that stock over two inches thick often takes a week to ship, leading to long production time for large ABS parts. Additionally, due to stricter environmental regulations on the West Coast of the U.S., large pieces of ABS are only manufactured in the Midwest and on the East Coast. It is also not an exceptionally strong plastic. DrawbacksĪBS does not have good abrasion or chemical resistance and will melt in acetone. ABS CNC Machining ProcessesĪBS is an excellent choice for general purpose prototyping, pre-molding prototypes, parts that will receive impact and require toughness, or when low cost is desired. ABS CNC machining involves cutting or engraving using a CNC milling machine. ABS machining will leave a matte finish, although it can be somewhat shiny, depending on how it is machined. It is also easy to finish, as it can be readily painted, glued, or welded together. It offers high impact strength, toughness, and electrical resistance at a low price. ABS Plastic CNC Machining OverviewĪBS is a well-rounded general use plastic that is widely used. If you know your part should be plastic, but you’re not sure if it should be CNC machined or 3D printed, check out this article first. I’ll provide a material properties overview, advantages, disadvantages, and common uses for:

For more information on a broader selection of plastics for CNC machining, check out Fictiv’s full range of capabilities on under “Materials” in the navigation. For the purposes of this article, I’m going to narrow the selection to several of the plastic materials offered by the Fictiv platform for CNC machining. In this guide, I’m going to help you align your project needs with the right material for CNC plastic part machining. In general, CNC machined plastic components make excellent prototypes and are readily available. There is a plethora of machinable plastic to choose from for plastic machining in 2022, each with its own combination of properties. If you decide the part should be plastic, and it should be CNC machined, the selection does not simply stop there. The first step in designing a part is to determine what material it should be made out of.
