Loading your file into the software File > Open Files...then search for your CAD model (typically in .stl format) and then hit OPEN. You can then re-orient, scale, mirror, position etc your model on the bed. It will be then ready to prepare the model by slicing it up and this will be turned into G-Code by hitting the SLICE button (bottom right).

Note that it will take a few minutes to warm up the printer bed before the actual printing will start.

Gap and wall measurement data We then measured the actual gap and wall dimensions with our trusty calipers. Here is the data.

Things to Avoid ● Do not print out pieces that could be easily be made by hand or with another machine e.g. laser cutter ● Very thin or small items will not print ● Long flat strips are hard to make as they tend to warp. ●...

● If it needs to be more solid we can stipulate an infill normally 5 – 50% to make it heavier and stronger.
