![]() It’s a high-performance filament that you only bring out when absolutely needed. It was never meant to be the type of filament that you could use to print things just for fun. PEEK is a very intimidating filament because of its high demands, in terms of both price and 3D printing parameters. ![]() Although it’s perfectly understandable why PEEK is so expensive, we are hoping that improvements in technology and growing demand can drive down the prices soon. At this price tag, we don’t expect many casual 3D printing hobbyists to buy a spool of PEEK filament just to try it out. One of the major hurdles to the widespread use of PEEK filament is the fact that it’s very expensive – easily four to five times the cost of an equivalent spool of ABS or PLA. You will have to slow down this cooling process so that the filament remains just hot enough to create molecular bonds across the layers. Since PEEK prints at very high temperatures, it also cools very rapidly as soon as it exits the nozzle. However, this is a characteristic that you will only experience if you follow the proper 3D printing fundamentals. This means that prints made with PEEK have almost equal strength across all three dimensions. Good layer adhesionīecause of the very high temperatures at which PEEK prints, it usually exhibits very good layer adhesion. It’s also very resistant to biodegradation and breakdown by UV radiation, which makes it an excellent material for items meant to be used or displayed outdoors. This makes PEEK suitable for functional parts that go through regular movement or are subjected to sudden or sustained pressure. Like ABS or Nylon, prints made with PEEK filaments are also exceptionally strong and rigid. With thermal stability of up to 250 ☌, PEEK is a suitable material for many engineering processes or medical instruments and prosthetics that need to be sterilized at high temperatures. As you would expect, PEEK has thermal stability unequaled in the world of 3D printing filaments. The difficulties of printing with PEEK filament pay off when you realize just how robust the finished product is. If you’re planning on printing with PEEK, you’ll have to be very discerning about the specs of your 3D printer. This property sets PEEK filament apart immediately because not many desktop 3D printers are capable of achieving such temperatures. Correspondingly, you will need a heated bed that can be set to as high as 120 ☌. To print with PEEK, you need a 3D printer that can heat up to 360 to 400 ☌. ![]() We may consider ABS or Nylon as “high-temperature filaments,” but neither of those two even come close to the temperatures needed for PEEK. Here are the characteristics of PEEK filament that makes it quite unique: 1. However, this also corresponds to a much higher price tag. It’s classified as a high-performance filament, which means that it exhibits better overall properties. PEEK belongs to a class that’s a little different than most of the other 3D printing filaments. For these high-performance applications, PEEK is typically processed using extrusion or injection molding methods. It has also been used in the field of medical implants, such as for replacement skeletal components. ![]() Because of its excellent physical and chemical properties, PEEK has been used to manufacture engineering parts such as piston parts, pumps, bearings, compressor valves, and electrical cable insulation. With a tensile strength of 90 to 100 MPa and a Young’s modulus of 3.6 GPa, PEEK is both rigid and strong.Īpplications of PEEK can be derived either from its solid form or by 3D printing from its filament form. It has a high resistance to biodegradation, chemical degradation in organic and aqueous environments, and can have a useful operating temperature range of up to 250 ☌. It is created by a step-growth polymerization process conducted at very high temperatures. PEEK stands for Polyether Ether Ketone, a semi-crystalline thermoplastic that is well-known for its excellent mechanical strength and chemical resistance. What makes PEEK filament so special? What are the best brands of PEEK filaments available today? What is PEEK filament? One of the products of these efforts is PEEK filament. ![]() Since 3D printing came into fashion, manufacturers of 3D printing filaments have made a lot of efforts to make products that are just a little more resilient and sturdier. Depending on the filament, your 3D print can melt in extreme temperature, quickly deteriorate when exposed to UV radiation, or fail spectacularly upon sustained or sudden impact. Objects made from 3D printing are known for capturing the imagination and turning it into reality, but they aren’t exactly known to be durable. 3D Insider is ad supported and earns money from clicks, commissions from sales, and other ways. ![]()
