The device is a simple briefcase-like dry box but works well to keep the active filament in a humid-free environment, ensuring safe long-term storage for optimal filament performance. One noteworthy feature of the Mark Two is the external spool holder included with the system. Naturally, at this price point, users also have access to Wi-Fi connectivity. Markforged has chosen to opt for a Linux-based interface which we found to be extremely smooth and lag-free, so big win there. Supporting multiple language options, the control center allows users to calibrate the bed, load up filaments, and initiate and stop print jobs. Both nozzles are backed by Bowden extrusion systems rather than direct-drive extruders, but Markforged has still been able to print flexible TPU filament with great repeatability in an R&D environment.Īs far as quality of life features go, the Mark Two sports a 4” full-color touchscreen with a clean and refined UI. The maximum hotend temperature clocks in at a potent 300☌, enabling the machine to print with Onyx filament, and Nylon, Carbon Fiber, Fiberglass, Kevlar and HSHT Fiberglass continuous fiber reinforcement. Compared to an IDEX configuration, the standard dual extruder will be heavier and less accurate on the X-axis but lighter and more accurate on the Y-axis. When it comes to the printer’s extrusion capabilities, the Mark Two features a single printhead housing a dual nozzle assembly. As a bonus, the magnetic print bed is also removable, making part reclamation simple and easy. This is crucial for higher temperature filaments such as Nylon as it helps avoid the delamination and warping issues that occur when a part shrinks due to cold airflow. Although the bed isn’t heated, the frame is fully enclosed to ensure the chamber is always warmer than the ambient conditions outside the printer. The Mark Two sports a build volume of up to 320 x 152 x 154mm, which isn’t large by any means but provides enough workspace for most medium part applications. Specifically, the belt configuration is purpose-built to minimize torque on the gantry while still allowing for rapid printhead motion, and the linear rails are precision machined to maximize accuracy. Compared to a standard cartesian setup, the system is more rigid, faster, and more accurate. Looking inside, we see that the printer is based on the T-Belt axis system, a configuration developed and used exclusively by Markforged. This is the kind of craftsmanship we expect from an NYSE-listed 3D printer manufacturer. Weighing in at just 16kg, we can’t help but feel the system would make a great visual addition to any workbench. The sleek aluminum chassis is minimalist, has an extremely robust feel to it, and simply looks like a premium piece of kit. Upon unboxing the system, it’s more than apparent just how much effort has gone into the build quality of the Mark Two. The turnkey package includes the printer itself, a set of hand tools, a filament storage box, a spool of Onyx filament (PA6-CF), and five additional spools of fiber reinforcement filaments: 2x Carbon Fiber, 1x Fiberglass, 1x High Strength High Temperature fiber, and 1x Kevlar. In the box, you’ll find everything you need to embark on your composite 3D printing journey. Operating on the firm’s Continuous Fiber Reinforcement (CFR) technology, the system is defined by its ability to integrate continuous fiber reinforcements into polymer parts, resulting in builds that are stronger and more impact resistant than conventional FFF.Īimed primarily at engineering professionals and manufacturing enterprises, the Mark Two is priced at a hearty $19,990 but we’ll soon see just how much bang you get for that buck. Markforged’s flagship desktop composite 3D printer is the dual extrusion Mark Two.
