A General Overview of taulman3D Materials
618 was the first nylon specifically formulated and processed for 3D Printing.
Technically, nylon 618 is an extremely high quality variety of nylon 6,6. Only one chemical company manufactures this specific variation of nylon. Both the chemical composition and post processing developed by taulman3D work together to lower the print temperature of high quality nylon as well as reduce the non-uniformity that nylons exhibit in the melted state.
618 is a pure white polymer and fully capable of absorbing acid based dyes. 618 printed with 100% fill rivals it's injection molded equivalents in strength. All of the feature of nylon that we come to depend on are at the maximum in 618. Slippery surfaces, pliability, strength, non-scrape, chemical resistance and high thermal durability.
645 was a result of the feedback from the industrial community that had started using nylon 618 as 618 was released about 6 months earlier. The industrial community made requests for a higher strength nylon, as well as a polymer that was easier to evaluate in the final part/print. taulman3D worked with industry to develop nylon 645. Nylon 645 is a nylon 6/9, or a variant of nylon 6 and nylon 6T with a crystallinity optimization process. This provides a high degree of transparency. The transparency allows the industrial quality control groups to evaluate printed parts without destructive evaluation. They can easily look through the perimeters and make a determination as to the adhesion of inner fills.
645 is a 50% transparent white color. It has a higher strength than 618 and is about 20% less pliable. 645 will dye with acid based dyes. Even though the polymer is less pliable, it maintains the slippery surface feature of nylons. Also as a nylon 6T variant, clumping is almost non-existent. 645 is a preffered polymer when parts to be printed will be subject to high stresses. As an extremely durable polymer, it handles stress at elevated temperatures. Depending on use, as high as 160C. 645 has the same chemical resistance as 618, but has 20% more resistance to chlorides.
t-glase is a high quality Polyethylene terephthalate polymer. It is modified to provide a 5% higher amount of reflectivity making it more equivalent to a glass polymer. t-glase is also processed using the same techniques taulman3D developed for nylon. Full processing allows for a polymer that easily prints at 235C - 242C. A temperature easily obtained by all FFM 3D Printers.
t-glase is also a high strength polymer meant for industrial applications. The major advantage of t-glase to all other polymers, is layer to layer bonding. Because the polymer bonds so well, there is no need to smash a large number of thin layers together to accommodate a good bond. Industry uses layer settings that are 70% to 100% of the nozzle dia with excellent results. t-glase has a very low shrinkage factor and is best printed on acrylic or glass print beds heated from 50C to 80C depending on part size.
As with nylon 645, 680 and 910, the clarity of t-glase supports industrial non-destructive evaluations. In addition, t-glase is a directly printable polymer for glass clear jewelry.
Users should watch the blogs for new 3D Printing jewelry designers to start advertising.
And due to the additional reflectivity, t-glase is considered the only high transmission light-pipe polymer. Due to it's chemical make-up, light transitions easily along the path of a printed thread. This allows the designer to draw and print a light-pipe with any path required.
t-glase can not be colored with standard dyes. Instead, special dyes are injected at the output master die during manufacturing.
t-glase comes in the following colors:
- transparent Blue
- transparent Red
- transparent Black
- transparent Green
- transparent Aqua
- New opaque White - an excellent white without a "chalky" appearance.
680 is a medical grade nylon made with a FDA approved polymer. Post processing allows for smooth 3D printing in the same temperature range as other taulman nylons. 680 is slightly more transparent than nylon 645. Again, this is to support non-destructive visual inspection of the printed part. 680 comes with 2 QR codes. One is for technical information needed by 3D Printers. The 2nd is for traceability. 680 is a non-leaching FDA nylon that's capable of low temperature sterilization techniques. Specifically, Ethylene oxide and high temperature sterilization as in Flash Steam post processing. 680 is much less pliable than nylon 645 as it is intended to support a long list of medical uses. 680 is currently in community testing.
NOTE: Nylon 680, will be a controlled material as to date code, batch code and processing codes. Available to everyone, each user will be automatically assigned a "User ID". This allows each spool to be traced back to taulman3D for verification.
Unlike our other products, 680 will be labeled on both spool flanges and no additional labels are allowed.
680 will not be available for sale this year as the certification process is at least 6 months long.
910 is the first 3D Printable High Impact, High Durability co-polymer Alloy with a tensile strength of 8,100PSI, thus matching 10-15%% glass filled materials! Alloy 910 is meant for high temperature high strength high durability uses. Alloy 910 is an excellent material for molding , Robotics, Machining or any need that requires a High Tensile feature along with high durability. Due to Alloy 910's chemical composition, it has the least water absorption of all similar materials containing a Nylon component.
PCTPE is a newly developed highly flexible 3D Printing material. PCTPE stands for "Plasticized Copolyamide TPE" or a chemical co-polymer of highly flexible nylon and TPE (thermoplastic elastomer) . PCTPE has several unique features that allow any user to print a highly flexible part with the added durability of our nylon polymers. This combination of polymers was developed specifically to allow anyone using current FFF 3D Printers to print parts from durable prosthetics to complete cosplay wearable outfits, cell phone enclosures as well as highly flexible utility/industrial parts. The flexibility of PCTPE means that the end parts will have the smooth lustrous texture of nylon, the added flexibility offered by a rubber like TPE, yet maintain the high durability and non-delaminating benefits of all taulman3D Printing materials.
Like all taulman3D Nylon materials, PCTPE takes on acid based dyes for any color desired. It's stock color is a bright gloss white.
A major feature of PCTPE is that even at 1.75mm and with it's high flexibility, it will not fold, bend or dislodge in the extrusion path of 3D Printers, a common issue with other flexible materials. PCTPE prints at ~ 235C on a heated glass bed set to 45C with a layer of PVA.
guidel!ne is a unique high strength PETG based material with excellent high temperature printing capabilities. Users know that printing small features of some parts can be difficult due to thermal build-up. guidel!ne is much less susceptible to these thermal issues allowing for finer detail without distortion. guidel!ne is also released as a starting point for individuals and companies wishing to obtain eventual FDA/CE certification for a device knowing that the raw material itself is listed with the FDA and has already passed specific FDA testing. guidel!ne is sold as a raw material modified in form only into 3d printing line and most important, extruded in a manner that keeps contaminates out of the material during the cooling process, where contaminates and bacteria could be embedded in the soft extrusion. In addition, pH and ORP levels are monitored and adjusted to maintain acceptable levels
Recognizing a growing need for 3D printing materials with higher durability as well as unique flexibility, taulman3D and DuPont Packaging & Industrial Polymers (DuPont) worked together to manufacture and release a unique new flexible material to the 3D printing community called T-lyne that uses DuPont™ Surlyn® ionomer. T-lyne is a unique, crystal clear polyethylene co-polymer developed specifically for high durability, flexibility, unique viscosity and a wide temperature range. Glass-like aesthetics can easily be obtained at high layer sizes using low speed and low temperatures in the range of 190 C to 210 C. Utility style parts are easily printed faster at standard layer sizes using higher temperatures up to 245 C, depending on nozzle size. DuPont™ Surlyn® in T-lyne meets FDA 21CFR 177.1330(a) and can potentially be used in prosthetics where the most unique feature is the ability to immerse a part into hot water, make some minor adjustments, then cool the part and the part will maintain the adjustments as if it were printed in final form. For years, clinics have used polyethylene braces, temporary casts and corrective positioning components to more closely match the end user’s exact needs. The clarity of T-lyne allows one to see into or through a part with as many as 5-8 perimeters and determine where adjustments may be needed. This same clarity is used for non-destructive evaluation of any printed utility part as internal adhesion is paramount. Also, T-lyne has a surface that is not slippery, making hand tools made from T-lyne unlikely to slip out of one’s hand.
BluPrint is a “specialty” material and has a Tg of 110C+ but with a print temp of only 265C. Prints on warm (45C) BuildTak and on clean glass heated to ~92C. Also prints on heated PIE sheets set to 55C. BluPrint is a semi-clear material of ~ 84% transmission. Like all taulman3D materials, BluPrint is a 100% bonding layer to layer polymer when printed at defined temperatures. A significant advantage of BluPrint is that when paired with the new E3D Volcano hotend, users and industry can print at speeds of 44mm/s with a 1mm nozzle and .46mm layer. As layer and nozzle size go down, speeds increase as expected to 120mm/s with a .4mm nozzle. BluPrint will allow designers to 3D Print parts that will take high heat for outdoor use such as part replacements for Autos, Boats and Aircraft.
Nylon 230 is the fist nylon ever developed to be printed at 230C or a lower temperature than any other 3D Printing Nylon. With the release of Nylon 230 (summer 2015), taulman3D will provide owners of PLA only or PLA and ABS only 3D Printers to add high strength Nylon to their list of material choices. In addition, Nylon 230 prints on Blue tape, and even better on "built-tak" type surfaces as well as print bed treated with various PVA glues/glue sticks.
