Alloy 910 is a measurable advancement in 3D Printing materials technology from taulman3D. taulman Alloy 910 is the combined effort of chemical companies, extrusion manufactures and taulman3D to specifically develop a single material to meet as many high performance 3D Printing needs as possible. With a combined tensile strength higher than the strongest co-polyesters, the durability of Nylons, a shrinkage factor that rivals our t-glase, a vast range of chemical resistance and a 95C working range, you now have one solution easily printable at 245C.

Dubbed "Bridge" by our local St Louis testers as bridging the strength of nylon 645 together with the price of current ABS and PLA thermoplastics, allows any user the flexibility to determine the best choice in material for their printing needs.
From our customers, we have logged and prioritized the most sought after features of a high strength printing material. These were in order:
A Lab certified measure of tensile strength.
Better Adherence to the Printing platform.
Reduced water up-take from local humidity
Non-destructive evaluation (Opacity)
Starting with our strongest base polymer used for a percentage of nylon 645, we began working all of these requests.
Adherence to the Printing platform:
First, was the adherence to the Printing platform. Those that follow the use of nylon in posts, blogs and 3DP discussion rooms know of using garolite (LE) as a print surface. While this works well for all of taulman3D nylons, garolite is not always easy to acquire and even so, requires a properly cut section that fits each user's unit. Our thanks goes out to our chemical company for helping to change this requirement. The surface properties of most nylons is extremely slippery making adherence to the printing platform difficult. Our chemical company was able to make minor adjustments, to reduce the surface effect just slightly, thus allowing for the use of most PVA glues, either full strength or diluted. Initial testing shows that in some cases, the PVA was better with Bridge than garolite is with 618. Thus, some dilution was used. The specific PVA used in our labs is a very low cost "ELMER'S Glue-All" White PVA.
Reduced water up-take:
Next was Reduced water up-take from local humidity. While it is not possible to eliminate the water uptake by nylon, it is possible to localize it to the surface through final processing changes. Therefore when printing, rather than water creating a subtle popping that can effect the surface finish, Bridge will hold the water to the outer portion resulting in a slight steam when wet. The result of this is that Bridge needs little or no drying in the winter and just needs to be warmed in the summer months. This is a manufacturing process that our extrusion house developed and added to our existing taulman3D processes.
We found that the same process that reduces water uptake also helps to reduce shrinkage. While nylon will always have a slightly higher amount than ABS, we were able to reduce it to an in/in value less than our current nylons. These changes also led to a slight reduction in stringing as the extruded threads are a thicker melt.
Non-destructive evaluation of 3D Printed parts is a function of the transparency of Bridge. Like nylon 645, this transparency allows for visual inspection of printed parts. This is a combined request from our industrial and clinical customers. As noted early on, parts can be printed "too fast" for some polymers. While the outside of the part may look acceptable, a part printed too fast will not have internal fill material that actually adheres to the inside of the perimeter. With Bridge and nylon 645, Non-destructive evaluation is a simple visual verification.
Taulman PCTPE, 1.75mm filament for 3D Printers.
Building on the success of previous Taulman Nylons PCTPE is a modified Nylon that is very flexible and somewhat elastic. This material is very easy to work with and has little warp with a heated bed and UHU Stic, as well as extruding cleanly and easily at 235C.
PCTPE is not as elastic and rubbery as flexible filaments like NinjaFlex, and provides a material option somewhere between the flexibility of standard nylons and "true" flexible filaments. Applications that require flexibility but low stretch and high strength such as timing belts and flexible hinges make PCTPE a really practical addition to your 3D printing arsenal. PCTPE is extremely tough and forms excellent inter-layer bonds, it can withstand being repeatedly flexed and is very strong.
The main features of t-glase
Strength - Specifications on the strength of t-glase will be posted as soon as the data is returned from the test labs. We have started using a local test lab along with the lab's at a few universities to accumulate data. The process involves printing several "test bars" These are bars printed at 5" x .5" x .25". The setup for printing these is 1 perimeter and 100% solid layers.
Temperature - Optimum temperature is about 235c to 240C, but will print down to 230C and up to about 248C.(NOTE: An early misprint had t-glase printing at 212C and should have been 232C to 238C)
NOTE: A feature of t-glase was to select a polymer that easily sticks to heated acrylic and glass print tables for the smoothest bottom surface possible. While t-glase meets this requirement, it results in a low glass transition temperature. The effects of a low TG is that parts printed in t-glase, should not be exposed to high temperature use or applications. The measured TG of t-glase is 78C.
FDA approved – t-glase is specifically made of FDA approved polymers for direct food contact/containers. This includes cups and other liquid storage parts as well as utensils. We are working with the chemical company to provide you with FDA related documentation so you may sell your printed parts that meet FDA requirements. These documents will be posted below when available.
Environmental - While t-glase is not biodegradable like PLA, it is a material that’s considered 100% reclaimable. Thus the new “struders” that convert failed prints back to usable line work perfectly with t-glase. If you have a “struder”, you can actually mix in 12% of the total weight in discarded clear water bottles. Please keep in mind, that the polymer used in most water bottles, has a slightly higher melt temp and that adding them to the mix, may increase print temp a few degrees.
Clarity – t-glase is considered colorless per industrial classifications. t-glase is considered "water clear" as it will not degrade to a color in multiple layters of applied thickness. t-glase’s clarity supports industry’s requirements for non-destructive evaluation of 3D Printed parts.
Shrinkage - Very low shrinkage makes printing large flat surfaces a breeze. And it easily prints to acrylic, glass, Kapton and other platforms.
Bridging - Those of us that have printed with acrylics and poly carbonates are always envious of their bridging capabilities due to glass temperature. And the new t-glase is very impressive at bridging.
Fumes - Unlike some lines, there are no odors or fumes when 3D Printing with t-glase.
