Peek plastic 3d printing12/14/2023 You can see more details on the extruder in the link in my signature. I would be using my E3D-v4 All metal extruder, which has 316 Stainless and brass in contact with the molten plastic. Resin pellets are much more available than filament.Īs far as I know neither are particularly harmful to the processing equipment. I am going to invest in a filastruder or similar at some point once they are a little more prove - or make my own. My stumbling block in both respects is acquiring filament. I have considered printing both PEEK and FEP (Which is a fluoropolymer like PTFE, but can be conventionally melt processed as a thermoplastic) Remember, you're all RepRap developers (once you've joined the super-secret developer mailing list), and the wiki,, is for everyone and everything! Let us know how it's going in reprap-dev, eh? Since you're a dev. You may also have trouble with your splines not gripping the teflon, but some (if not all?) of our stuff works with hdpe, which is quite slippery, so ? I'd also worry about the plastic parts of your extruder melting since you may be running your hot end higher than normal. You'll probably want to pipe the fumes out a window.Īlso, you'll probably want to try a hot end with no ptfe/peek parts, like: Sounds like it's going to be off-gassing quite nastily before it gets soft enough to extrude. These degradation byproducts can be lethal to birds, and can cause flu-like symptoms in humans. While PTFE is stable and nontoxic, it begins to deteriorate after the temperature of cookware reaches about 260 ☌ (500 ☏), and decomposes above 350 ☌ (662 ☏). Animal studies indicate that it is unlikely that these products would be generated in amounts significant to health at temperatures below 250 ☌ (482 ☏), although birds are proven to be much more sensitive to these decomposition products. The pyrolysis of PTFE is detectable at 200 ☌ (392 ☏), and it evolves several fluorocarbon gases and a sublimate. – a unit specializing in providing equipment and services in the 3D printing industry. PEEK plastic at 3DShop Vietnam is genuine imported from Europe. If you are looking to buy PEEK for 3D printing, you can safely choose.According to DuPont, its melting point is 327 ☌ (621 ☏), but its properties degrade above 260 ☌ (500 ☏) PEEK materials are not really popular in Vietnam because the cost is somewhat higher than other 3D printing materials. And at present, there are not many enterprises that own PEEK production technology in Vietnam. However, if you need to buy PEEK materials you can look to 3DShop Vietnam . This is a sales channel under Smart Design Labs Vietnam Co., Ltd. This high performance material is especially attractive to the medical industry. As it is disinfectable and can also be used in production of on-demand implants. In addition, PEEK has the same properties as human bones: so 3D implants printed with PEEK can accelerate the regeneration of tissues around the implants, speeding up bone integration.Īerospace and automotive are also popular markets for PEEK 3D printing. It’s also wear-resistant and heat-resistant, and is also very light. These are all paramount requirements in the fields mentioned above. > See also: 3D printed plastic – ABS plastic 5. If PEEK is a demanding material, it must also be said that it offers interesting mechanical and chemical properties to the industry. PEEK’s advantage is that it is very resistant to heat and abrasion, its chemical resistance is also good, it can sterilize and has dielectric properties. Not only that, the strength ratio of PEEK is also high and is often used to replace certain metals. In particular, PEEK is also flame retardant, making it an interesting 3D printing material for fields such as aerospace, where there is a high fire / smoke restriction. Things to note when 3D printing PEEK materialsĭuring 3D printing, the crystallization of PEEK must be controlled. A part of the material will crystallize, changing the density of the material. Therefore, high temperature levels – extrusion, masonry and sheathing – must be maintained and variations in temperature are avoided. To print a PEEK 3D print, you will need a 3D printer with an extruder that can reach 400 ° C, the chamber is heated at 120 ° C and the platen up to 230 ° C to remove the part and prevent warping. If we look at the structure of PEEK, we can see that it is a semi-crystalline polymer. Therefore, when melted, its molecules arrange themselves under the effect of heat, creating a certain order until the material is completely solidified. This allows PEEK to maintain its mechanical properties as temperature increases. While this semi-crystalline structure has many advantages, attention should be paid to additive manufacture in the manufacture.
