====Overview====

====Operation====

The Mark II is a [[Prototype Lab#FDM Printing|FDM Printer.]] See the main page for more background on the 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.

Prints on the Markforged must be started by a manager, as the software is account based.

# Printer Setup

# Printer Setup

## The printer may be turned on with a switch on the rear of the machine. The machine will boot up and may need to update, let it complete this process.

## Before starting the print, glue needs to be applied to the build plate. Simply lift the build plate off the mount and apply the glue stick (found in the Markforged drawer/box) to the area where the print is located in the software (be sure to account for extra width due to the brim), the back of the plate where the machine will purge (print excess material which has been sitting in the lines and exposed to air), and the corner where the purge tower is located in the image below.

## Upon completion of the part, select clear bed on the touchscreen and remove the build plate from the mount. The purge line and tower should be easily removable by hand.

# 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”.
