The MarkForged Mark One: 3D Printing the World’s Strongest Parts


In today’s blog post, we want to talk about synthetics, strength and savings, and specifically, about some of the newest, most advanced materials used in modern manufacturing: carbon fiber, Kevlar, fiberglass, and nylon filaments used to create fiber-reinforced composite parts.

Just a few years ago, using sophisticated filaments such as these required a significant capital investment for custom-built molds – in the realm of tens of thousands of dollars – that put it out of reach for many businesses.  Well, forget about it – with the advent of the Mark One 3D Printer from MarkForged, the era of expensive fiber fabrication is already ancient history.  Because of its new, unique printing process, the Mark One can print fiber-reinforced composite parts with unparalleled strength and flexibility at a fraction of the cost.

Let’s do the numbers:

  1. Nylon Filament. As tough as it is flexible, nylon filament is an ideal protective layer for tooling, fixtures, tabs, clips, and fasteners.  The Mark One prints it at $3.65/cubic inch ($0.22/cubic cm.)
  2. A cost-efficient alternative to carbon fiber that will surprise you with its strength and electrical insulating ability. The Mark One prints it at $10.96/cubic inch ($0.67/cubic cm.)
  3. The composite that’s so tough, the US military uses it for body armor – so you can trust it when printing your strongest, sturdiest parts. The Mark One prints it at $18.83/cubic inch ($1.15 /cubic cm.)
  4. Carbon Fiber. Stiffer and stronger than aluminum, carbon fiber is safe and non-toxic, and the best choice for fixtures, jigs and other parts that need maximum strength without tipping the scales. The Mark One prints it at $25.34/cubic inch ($1.55/cubic cm.)

 But wait, you’re saying.  3D printers aren’t exactly new, and there’s a reason you haven’t already made the switch. You don’t want to deal with messy ABS plastics, horrid-smelling chemicals, extra process steps or post-cure delay.

The Mark One changes everything. It uses nylon instead of ABS, which is almost completely odorless; the materials harden during printing, there is no post-curing, and the process of prototype-to-printed-part is simplified and streamlined by MarkForge’s unique software. 

Perhaps best of all, you’re not just saving a huge amount of money – you’re also greatly increasing the quality of your parts. The Mark One’s new 3D printing process, called Composite Filament Fabrication (or CFF), creates composite parts that are up to 20 times stiffer and 5 times stronger than ABS plastic parts.  Every one of your products will be constructed of the highest quality materials, designed to withstand unthinkable physical rigors and featuring the same strength and durability relied on by NASA, SpaceX and other space programs around the world.
