9/16/2023 0 Comments Peek material full formRecently however, lower cost 3D printers have emerged that can 3D print PEEK. Most PEEK 3D printers are industrial machines, requiring skilled operators and costing tens of thousands of dollars. Struggles with chemicals like chlorine and sulfur.UV resistance: somewhat susceptible to UV radiation, though PEEK has good X-ray resistance.Lack of color options: unlike with filaments like PLA, you are restricted to mostly white, beige or black parts with PEEK.Therefore, it is reserved for high value added industrial applications rather than beginner 3D printing. Commonly a kilo of PEEK filament will cost upwards of $500. Expensive: PEEK is one of the most expensive materials you can 3D print with.Imperfections can easily occur if any factors deviate from their optimum. Difficult to print: PEEK requires extremely high extruder temperatures, with a heated bed and precisely managed heated chamber.High quality prototyping: PEEK is the best filament for the rapid prototyping 3D printing of functional parts that need to be tested under extreme conditions.In sectors where weight saving directly translates into larger profits, such as in aerospace, PEEK is replacing heavier aluminium parts. Lightweight: offers steel-like strength, at a fraction of the weight.PEEK is increasingly adopted in the medical and dental industries for a variety of implants as a result. Sterilization uses: PEEK doesn’t react badly to steam or boiling water, so is ideal for applications where it needs to be sterilized.High temperature resistance: commonly used in applications where it may be heated over 200C, without any adverse reaction.Fantastic strength and mechanical properties: not only is PEEK hugely strong, but it also resists chemicals well, such as acetone which heavily affects ABS. 3DJake UK & Europe PEEK filament selection.We recommend the following PEEK filaments for use in high-quality rapid prototyping projects: PEEK filament is expensive - and can cost $300-500+ per kilo - but the benefits are clear: extremely high quality parts can be produced. This ensures better quality and consistent parts with less errors - which are very expensive to make using PEEK filament. PEEK is prone to warping, so you will need a heated bed heated to a minimum 120☌, preferably 120-150☌.įor build surface to enhance adhesion, glue stick, hairspray or high temperature Magigoo work well on glass, as well as PEI sheets.Ī recommendation is to print slower with PEEK. You should also ensure printing cannot be affected by any extraneous variables like sunlight. PEEK filament is very sensitive to even slight changes in temperature, so a heated chamber is required. You will also need an enclosed, heated chamber. Minimum extruder temperatures are around 360☌, and you may need to be higher at 400-450☌ depending on the filament and other factors. As a result, you’ll need an all-metal hot end and very high-end nozzle such as a hardened steel nozzle. PEEK melts at around 343☌, with a glass transition temperature of 143☌ – both much higher than standard 3D printer filaments. PEEK is also increasingly combined with other materials such as carbon fiber or glass fibers to create strong composite materials for industrial uses. For PEEK 3D printers, read our PEEK & Ultem 3D printer buyer’s guide. This article focuses on PEEK filament.With patents expiring for a number of innovations necessary for PEEK 3D printing, mostly concerning heated chambers to keep temperature consistent, PEEK 3D printer filament has seen an increase in use, with a number of specialist industrial 3D printers developed with PEEK additive manufacturing in mind. PEEK is predicted to become the most profitable segment of additive manufacturing, and account for 19% of 3D printing material revenues by 2026. It was developed by British company Imperial Chemical Industries (ICI) who are now defunct, but their PEEK material department was bought out by what is now Victrex, a London Stock Exchange-listed polymer company who manufacture PEEK today. PEEK was first marketed and sold over 40 years ago, as a niche material for aeronautics. Offering fantastic mechanical properties, and as strong as steel by volume despite being 80% lighter, PEEK 3D printing is fast becoming adopted for a variety of industrial weight-saving applications. PEEK, also known as Poly Ether Etherketone, is seeing increasing use in 3D printing in recent times, but has been around since the 1980s.
