We currently are transitioning to MatterControl for use with the 3D printers. Its icon lives on the desktop of the 3D printing workstation and can be seen on the right. Its use is suggested over the use of Slic3r and Pronterface, which are kept on the 3D printing workstation for historical value.

Opening MatterControl brings up the main window:

Printer Status | shows the status of the current printer, as well as allowing you to disconnect or connect to a different printer.

Shows the print queue for the current printer, as well as a library of printable objects and a history of the current print queue. This panel serves double-duty as the print settings and printer control views.

Displays the current object ready for printing. This view allows you to pan around the solid object, as well as view the generated G-Code.

This view allows you to adjust print settings. The two most common (and the only two that should really need adjusting) are:

• layer Height (determined by the preset for “quality”). These are in increments that vary from printer to printer
• Fill Density: The amount of material that the 3D printed object will actually be solid within the interior. Common values for this are: 1-20% (0.1 0.2) for decorative pieces, 50% (0.5) for light

1. Turn on the printer. For each printer, there is a switch which controls mains power.
2. Check the preflight list for the printer you wish to use.
3. Open MatterControl and connect to the printer you wish to use.
4. Add the model you wish to print to the MatterControl queue
5. Check settings for the model you wish to print, e.g. layer height (resolution) and infill density.
6. Press print. MatterControl should take it from there.

Use the Printer Status buttons to pause or stop a print while the printer is running. If you wish to immediately start printing again, be sure to preheat the printer using the temperature buttons in the Printer Status view.
