Writer\u2019s Note: This is the first of a two part post about using Eiger\u2019s Isotropic Fiber fill pattern to make extremely strong parts with a Mark Two. \u00a0In this post, we\u2019re going to review how to approximate the high strength lay-up patterns of traditional composites with a Markforged printer. \u00a0In the follow-up post, we\u2019ll tackle how to use these strategies for maximum strength in your reinforced parts.\u00a0We\u2019re going to get a bit more technical in this post\u00a0than we typically do in our blog, but we\u2019ll take it slow through the terminology (we\u2019ve included a short Composites Terminology Glossary), and we think you\u2019ll appreciate a more in-depth understanding about how to design effectively for composite-reinforced, high strength 3D printing.<\/i><\/h2>\n

A Composites Background<\/i><\/h3>\n

Markforged\u2019s continuous strand composite 3D printers enable our customers to create industrial strength 3D printed parts, reinforced with composite fibers to produce properties similar to quasi-isotropic composite laminates, in a highly automated 3D printing system. Quasi-isotropic 3D printed parts have varying material characteristics along different axes, and by varying the fiber orientation in our Eiger slicing software, you can design strong parts to resist specific loading applications to which the part may be exposed.<\/p>\n

High strength isotropic material* properties make engineering part design easy \u2013 if a material has the same properties in all directions, then making a part that is strong enough for an intended application is nothing more than a matter of geometry. In the case that material properties\u00a0will<\/i>\u00a0differ across different axes (as is the case in 3D printing), a quasi-isotropic* material is the next best option, since there is a strength difference along only one axis that must be taken into account and it will require much less time and design work to optimize for part strength than with a completely anisotropic* material. See the common terminology for composite material property orientation below for a deeper discussion of variations in material properties. Note that for convenience, and with the understanding that all 3D printed parts will have differing material properties in the Z direction (the axis normal to the printbed plane), Markforged has dropped the \u2018quasi-\u2018 from quasi-isotropic in describing our \u2018Isotropic Fiber\u2019 fill type.<\/p>\n
