Features
Adherence to the Printing platform:
Bridge can be used with 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. Taulman3D uses a very low cost "ELMER'S Glue-All" White PVA in their work.
Reduced water up-take:
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 holds the water to the outer portion resulting in a slight steam when wet. Because of this, Bridge needs little or no drying in the winter and just needs to be warmed in the summer months.
Reduced Shrinkage:
The same process that reduces water uptake also helps to reduce shrinkage and lead to a slight reduction in stringing as the extruded threads are a thicker melt.
Non-destructive evaluation: 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. 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: A fully accredited testing facility reported a Tensile Stress PSI of 4,800 for Bridge when 3D printed.
