"Nylon 680, an innovative new nylon-based material for Fused Filament Fabrication \r\n(FFF) 3D printing, is designed for use in a wide range of industries, including: \r\nmedical, dental, food processing, and robotics. Nylon 680 is compatible with \r\nsterilization procedures, has FDA approval for indirect food contact, and is \r\ndesigned to have superior strength and physical attributes when compared to \r\nconsumer-grade materials currently on the market; 680's specifications are \r\nhighly desired by industry and hobbyists alike.&lt;p&gt;\r\n&lt;b&gt;\r\n&lt;u&gt;\r\nFor Use by Medical, Dental, and Food Processing Industries&lt;/u&gt;&lt;/b&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\n&lt;b&gt;\r\nSterilization Properties&lt;/b&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\nNylon 680 is compatible with the following sterilization methods, used globally \r\nin scientific laboratories for conducting a wide range of research:&lt;/p&gt;\r\n&lt;p&gt;\r\nEthylene oxide sterilization compatible (Low temperature)&lt;/p&gt;\r\n&lt;p&gt;\r\nSteam/Boiling sterilization compatible (High temperature)&lt;/p&gt;\r\n&lt;p&gt;\r\nSterilization is important for researchers becaus e it removes all fungus, \r\nbacteria, and other microbes which may be detrimental to the conditions of \r\nexperimentation. Compatibility with sterilization processes is a rare material \r\nproperty in the 3D printing industry and is a unique attribute of Nylon 680.&lt;/p&gt;\r\n&lt;p&gt;\r\n&lt;b&gt;\r\nLab Applications include:&lt;/b&gt;&lt;/p&gt;\r\n&lt;p&gt;Scaffolds to grow cells&lt;/p&gt;\r\n&lt;p&gt;\r\nTissue engineering&lt;/p&gt;\r\n&lt;p&gt;\r\nPrototyping medical devices and prosthetics&lt;/p&gt;\r\n&lt;p&gt;\r\nOn-demand manufacturing of custom laboratory equipment&lt;/p&gt;\r\n&lt;p&gt;\r\n&lt;b&gt;\r\nUnder EU Consideration for Dental Applications&lt;/b&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\nDentists in the European Union are currently investigating this material for use \r\nin their practices; as such, it is currently under certification testing for an \r\nEU Dental CE marking, which would allow Nylon 680 to be used commercially in \r\ndentistry.&lt;/p&gt;\r\n&lt;p&gt;\r\n&lt;b&gt;\r\nFood-Processing Applications&lt;/b&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\nNylon 680 is approved for used in food storage and handling; it can be used to \r\nmake dishware, utensils, and food decorations where the alcohol percentage is \r\nless than 8%. It is also dishwasher safe.&lt;/p&gt;\r\n&lt;p&gt;\r\nSpecifically, Nylon 680 is manufactured to meet FDA\u00A0&lt;i&gt;21CFR177.1500. \r\nPART 177&lt;/i&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\n&lt;i&gt;\"INDIRECT FOOD ADDITIVES\" POLYMERS Subpart \r\nB--Substances for Use as Basic Components of Single and Repeated Use Food \r\nContact Surfaces.&lt;/i&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\n&lt;b&gt;\r\nVacuum Sealed and Traceable&lt;/b&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\nNylon 680 comes vacuum sealed and with a serial/batch number to allow \r\ntraceability. This allows you to be sure your filament has the aforementioned \r\nproperties.&lt;/p&gt;\r\n&lt;p&gt;\r\n&lt;b&gt;\r\nVeterinary Use&lt;/b&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\nDue to its unique properties, Nylon 680 is well-suited for use for veterinary \r\napplication including casting animals and developing custom prosthetics.&lt;/p&gt;\r\n&lt;p&gt;\r\n&lt;b&gt;\r\n&lt;u&gt;\r\nExcellent material for high-strength, functional 3D printed parts&lt;/u&gt;&lt;/b&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\n&lt;b&gt;\r\nStronger than PLA and ABS&lt;/b&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\nPrinted parts with Nylon 680 have been tested independently and are shown to be \r\nsuperior in strength when compared to other commercially available FFF 3D \r\nprinting materials, and even to injection molded parts with PLA or ABS.&lt;/p&gt;\r\n&lt;p&gt;\r\nIn laboratory testing, 3D printed samples of nylon 680 reached an average \r\ntensile modulus stress of 28,634 psi (197.42 MPa); in comparison, Nylon 645 \r\nreaches a tensile modulus of 27,141 psi (187.13 MPa).&lt;/p&gt;\r\n&lt;p&gt;\r\n&lt;b&gt;\r\nSupports Non-Destructive Evaluation (Transparency)&lt;/b&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\nNylon 680 has approximately 20% opacity, making it considerably more transparent \r\nthan Nylon 645. This is a major requirement for industry, as it supports \r\n\"Non-Destructive Evaluation,\" allowing users to confirm that their part printed \r\nproperly.&lt;/p&gt;\r\n&lt;p&gt;\r\n&lt;b&gt;\r\nPrecision 3D Printing (Low Shrinkage)&lt;/b&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\nNylon 680 has very low shrinkage, allowing for printing parts with tight \r\ntolerances; this means users who are creating functional parts with a specific \r\nsize requirement can be sure Nylon 680 is up to the task. Nylon 680 also \r\nmaintains the well-known nylon slippery surface as requested by clinics and \r\nindustry.&lt;/p&gt;\r\n&lt;b&gt;\r\n&lt;u&gt;\r\nSuperior Performance for Engineering&lt;/u&gt;&lt;/b&gt;&lt;p&gt;\r\nNylon 680 is also intended to trail blaze the path for 3D printing in robotics. \r\nThe robotics industry is currently developing new motors specifically designed \r\nto withstand high torque, with a minimal end-to-end shaft length. Motors with \r\nsuch designs will be the standard for articulated joints and will require \r\nnon-standard gearing as well as interconnecting hubs and mating flanges. Nylon \r\n680 is an attractive material to meet the aforementioned requirements, as it is \r\na high strength material with proven low-friction surface properties.&lt;/p&gt;\r\n&lt;p&gt;\r\nNylon 680 can be used to print the large parts necessary for creating drones and \r\nrelated robotics applications.&lt;/p&gt;\r\n&lt;p&gt;\r\n&lt;b&gt;\r\n&lt;u&gt;\r\nOther Applications:&lt;/u&gt;&lt;/b&gt;&lt;/p&gt;\r\n&lt;p&gt;\r\nIn addition, Nylon 680 can be used to print a wide range of functional items, \r\nincluding: glasses and other outerwear, wearable gadgetry, art, sporting \r\nequipment, durable custom parts needed for construction projects, and much more!&lt;/p&gt;\r\n\t&lt;p&gt;\r\n\t&lt;b&gt;\r\n\t&lt;u&gt;\r\n\tCare and Handling:&lt;/u&gt;&lt;/b&gt;&lt;/p&gt;\r\n\t&lt;p&gt;\r\n\tWhile Taulman nylon filaments are designed to avoid problems caused by \r\n\thumidity, nylon materials still inherently absorb moisture, which can affect \r\n\ttheir printability when the materials are not properly cared for. \r\n\tFortunately, absorption of moisture is completely reversible.&lt;/p&gt;\r\n\t&lt;p&gt;\r\n\t&lt;b&gt;\r\n\tTips for handling nylon:&lt;/b&gt;&lt;/p&gt;\r\n\t&lt;ul&gt;\r\n\t\t&lt;li&gt;In summertime, \r\n\t\tkeep nylons in a non-humid environment&lt;/li&gt;\r\n\t\t&lt;li&gt;Avoid storing \r\n\t\tnylons in an environment like a basement, which tend to be humid&lt;/li&gt;\r\n\t\t&lt;li&gt;Consider using a \r\n\t\tdehumidifier in your materials storage room&lt;/li&gt;\r\n\t\t&lt;li&gt;Consider using \r\n\t\tsilica gel packets to absorb moisture&lt;/li&gt;\r\n\t&lt;/ul&gt;\r\n\t&lt;p&gt;\r\n\t&lt;b&gt;\r\n\tBut what can you do if your material has been in a humid environment and has \r\n\tabsorbed moisture?&lt;/b&gt;&lt;/p&gt;\r\n\t&lt;p&gt;\r\n\tAs stated above, absorption of moisture is completely reversible. Drying \r\n\tnylon materials before using them for printing will remove almost all of the \r\n\twater molecules. You may use a blow dryer for this, or some desiccant \r\n\tpackets. Even if Taulman nylons are submerged in water for weeks at a time, \r\n\tthe process of water absorption can still be completely reversed. So no \r\n\tworries and print on!\r\n&lt;p&gt;&lt;b&gt;Nylon 680 Specifications:&lt;/b&gt;&lt;br&gt;\r\nTensile Strength = 4,686PSI +&lt;br&gt;\r\nModulus PSI =28,634&lt;br&gt;\r\nMax Elongation at break = 226% &lt;br&gt;\r\nPrint Temperature = 250C - 255C&lt;br&gt;\r\nNozzle size = Any&lt;br&gt;\r\nShrinkage = 0.006 in/in&lt;br&gt;\r\nTransmission = ~70%&lt;br&gt;\r\nColor = Subtle translucent Shell White when printed solid - May be dyed with \r\nacid based dyes.&lt;/p&gt;\r\n&lt;ul&gt;\r\n\t&lt;li&gt;Recommended Extruder Temperature: 245-250\u00B0Cli&gt;\r\n\t&lt;li&gt;Recommended Print Bed Temperature: 60-90\u00B0C&lt;/li&gt;\r\n\t&lt;li&gt;Recommended Print Bed Surface: Glass heated to 45C with thin coat of PVA&lt;/li&gt;\r\n\t&lt;li&gt;Recommended Print Speed: 20-30 mm/s&lt;/li&gt;\r\n&lt;/ul&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
