For the past few decades, the biggest roadblock to 3D printing has been materials. Many of the most common materials are weak and brittle, limiting 3D printing to modeling and fit prototyping. As the technology has advanced, so have its materials. Today 3D printing materials are better than ever. Prohibitively expensive materials that only multi-million dollar printers could produce are now becoming affordable. Tough nylons, stiff composites, and even metal materials are entering affordable price ranges for businesses and consumers alike. While stronger materials are available, proper use and education around those materials is equally important. Markforged printers are unique in their ability to lay continuous strands of carbon fibers inside 3D printed parts to achieve strengths comparable to metals. In this white paper, we’ll discuss efficient fiber routing strategies for Markforged composite printers so you get the highest Return On Investment.
