# '''Prepare a 3D model to print'''. You can [[#Find model online|find a model online]] with sites such as [http://thingiverse.com Thingiverse], or [[#Make your own|create your own]] in software such as Sketchup or OpenSCAD. You will need to save the model as a .STL file, however .DAE can also be used for direct exports from Sketchup.
# '''Import your model onto the print computer'''. It is easiest if you print using our dedicated print computer (Fixme-SPM) which is located next to the printer. You can import the model by dragging it into the [https://foo.fixme.ch/marcha/ drag and drop service], using a USB key, using IRC, or using a cloud hosting service such as [http://ge.tt/ Ge.tt] or [https://mega.co.nz/# Mega]. If you log into your email/dropbox/etc account on the machine, don't forget to use incognito mode.# '''Open Cura and open your model(s)'''. Open Cura from the sidebarActivities menu, and click on the [https://fixme.ch/w/images/d/dd/Cura-load.png Load button]. Select one or more .STL or .DAE files that you would like to print. Please note that prints that reach near the limits of the print volume (21 x 21 x 20.5 cm) will fail.# '''Adjust your model for printing'''. Use the Rotate, Scale, and Mirror button to print your model as you want.
# '''Configure your desired print parameters'''. The print parameters will depend on what you are printing and the quality that you're looking for. Here are some guidelines:
## '''Layer height''': the Ultimaker can print between 0.1mm 06mm and 0.25mm3mm. 0.1mm should only be used for high precision, high detail prints; 0.15mm should be used for normal prints; 0.2-0.25mm should be used for fast prints where you don't mind the quality (e.g. holder, internal component, etc).
## '''Shell thickness''': this value should be a multiple of 0.4mm (the width of the nozzle). With 0.4mm you'll get 1 solid layer, with 0.8mm you'll get 2 solid layers, etc. 0.8mm is fine for most prints.
## '''Enable retraction''': this retracts the filament when the nozzle moves from one area to another whilst not printing. It is best to leave this enabled.
## '''Bottom/top thickness''': the bottom and top thickness of the solid layer. This value should be a multiple of the layer height - a value between 0.2mm and 1mm is best for most prints, with 1mm used for very delicate models.
## '''Fill density''': this is the density of the fill inside your model. Due to an excellent calibration of our Ultimaker, almost all prints will require less than 30% fill. 10% for just structural support, 24% for an average print (after 25% Cura slices your model differently), 30% for a solid print of an average sized object. For objects that require superior structural strength, up to 60% is recommended. 80% can be used for very small complex objects, and 100% is can be used on a case-by-case basis (if you go at 100% on a large solid, there will be too much material for things like keys and it will be a mess)bottle openers.## '''Print speed''': this is the speed at which the Ultimaker will print. 60-80mm/s for detailed prints, 100mm/s is recommended for detailed most prints, 120mm/s for average prints, and up to 150mm/s for fast, lower quality prints.## '''Printing temperature''': we have tested and 235°C works best. Leave it as isSelect in the 210-240°C range.
## '''Support type''': only use for prints with significant overhangs.
## '''Platform adhesion type''': not required for PLA prints.
## '''Diameter''': the diameter of the filament (currently 2.89mm). Do not touch this unless you are changing the filament and have remeasured it (sometimes the value does not match the specification).
## '''Flow''': I have no clue what this doesthe rate at which the filament is extruded. If it ain't broke100% is the normal rate, donif you't touch itre having issues with extrusion you can increase this.
