It is hard enough to keep up with advances in 3D printing technology but there are equally amazing innovations being made in the material properties of printing filament. As an artist, the more you can understand about the materials you work with the better. It would be handy to have a database of the properties of different filaments, from various manufacturers, that a non-chemist/engineer could utilize. Anyone know of such a tool?
This news item is reporting on a particularly innovative filament manufacturer named taulman3D. One of their new materials is a nylon material that is very flexible while being very strong and should be a useful material for 3D printing wearable objects.
For those of you, like me, who are clueless when it come to fancy chemical names, this material is basically your typical flexible 3D printing filament on steroids. It is designed to work in virtually any FFF-based 3D printer capable of printing with ABS. Unlike many other flexible filaments that have issues printing on extruders that require 1.75mm filament because they are too flexible in their raw material form, PCTPE will not have this problem. This is because of a special “draw” process that taulman3D required their manufacturers to do. Basically it stretches the material during the final manufacturing process. This is a tactic utilized in the manufacturing of large nylon ropes used for large ships when docking, as it increases the ropes’ tensile strength. It also apparently works with filament, increasing its tensile strength as well. In turn the filament will not buckle or fold as much as will other flexible filaments.
