taulman is making a name developing different filament materials for extrusion/FFF based 3d printers with a specific focus on testing the parameters of the materials and sharing the results across the 3D printing community. The latest material development is taulman 645, which has just been made public after being tested by ‘just a few’ printer operators with further opportunities available for further testing.
The taulman 645 material offers some notable properties including very high strength (the expected tensile strength is quoted as yielding 16,533 psi) for both individual thread structures and thread-to-thread bonding, together with ‘extreme’ durability (expected elongation at break is quoted as 120 %). Furthermore taulman 645 has been designed to meet high optical clarity requirements when printed for LED and LCD overlays.
In addition this new material is said to exhibit excellent bridging performance; advanced chemical resistance, including to chlorine, chlorides and bromides, alcohols, resins+MEK, oils, acetone, most alkalines and most 2 part casting compounds; a superior surface texture; and full industrial visual non-destructive evaluation of internal fills.
The current measurement of taulman 645 (diameter) is 1.76 – 1.83 mm and is slightly oval in shape. Some limted feedback from testers has been published and can be viewed here.
The following video demonstrates the delamination and impact testing of parts 3D printed with taulman 645.
taulman is making a limited number of samples of the 645 material available for moretesters, at no cost other than shipping, to gain further feedback. More information on this can be garnered from the source link.
