Taulman Bridge Nylon
*Currently not compatible with UP printers, please try Alloy 910
The new material is named "Bridge" as it is a consolidated effort by thousands of nylon 618 and nylon 645 users along with the help and support of both our extrusion house and chemical company.
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.
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.
Certified measure of strength:
With this combination of advancements, taulman3D proceeded with a limited test run. From this initial test run, we printed test samples to be sent out to the St Louis test labs. A fully accredited testing facility supporting the central US. The lab reported a Tensile Stress PSI of 4,800 for Bridge when 3D printed.
taulman3D supports several industrial, commercial and clinical customers with nylon 645 and this has allowed us to meet all of our pricing tiers for certain chemicals used in 645. Because 'Bridge" is a very close chemical polymer to nylon 645, we are able meet these pricing requests.
Excellent filament, highly recommended!By: Daniel E. on 5 October 2016Excellent filament, highly recommended!
We are having great successBy: Jeff P. on 7 June 2016We are having great success with the Taulman Bridge nylon. It's a cracker of a filament. We run it through a flashed da vinci printer at 244 (first layer)/242 and bed 105/100. Sticks well enough using Bostick Blu Stick for even tall models, but doesn't stick so hard that it's difficult to remove. It provides us with pre-production prototypes representative of the sort of material we hope to be injection moulding. As always, 3D Printer Gear provide a fast response and great service.
I really like the bridgeBy: Hayden B. on 28 April 2016I really like the bridge material, not easy to print due to warping but does print small items well from 0.25mm down to 0.10mm, small amount of supports are normally fine to remove. Print on glass with thin film of Elmers, my printers have a heated chamber that I keep at 30 degrees (lowest it will go), print raftless for flat objects. This stuff is STRONG, when printed correctly it will not break. BIG NEGATIVE: It is often out of size so if you have trouble printing it check the diameter, it should print like ABS, if it doesnt it's either damp or out of size, one more thing.. it must be kept dry the whole time you are printing, no exceptions!
Good product, Good Value,Good ServiceBy: Lincoln B. on 29 May 2015Good product, Good Value,Good Service
Awesome stuff! So freaking strong!By: Isaac P. on 20 May 2015Awesome stuff! So freaking strong!
