====Overview====

====Operation====

The Mark II is a [[Prototype Lab#FDM Printing|FDM Printer.]] See the main page for more background on the Fused Deposition Modeling (FDM) process. What sets the Mark II apart is its ability to inlay various materials in the print using a second nozzle. These materials include carbon fiber, fiberglass, and kevlar. These smaller materials are located on the second, smaller spool in the rear of the build space. The inlaying of these materials can be customized in Eiger (the printing software for the Markforged). The main materials for the printer are nylon and onyx, this material is contained in the dry box (black box behind the printer) in order to limit moisture contamination. Don't open this unless you need to change the material. Nylon is a typical plastic filament, which provides a clean finish and some flexibility. Onyx is nylon with chopped carbon fiber. This provides more strength and a little less flexibility.

# Although this should be a non-issue, fiber strands are fairly thin and sharp. DON’T IMPALE YOURSELF.

# The top of the printer may be opened for maintenance and inspection. This leaves the gantry with the print head on it exposed. DO NOT PUT YOUR HAND IN THE MOVING MACHINERY. Doing so may result in pinching, crushing, cutting, “ouch”-ing, crying, and other unpleasant “-ings”.
