The Original Prusa i3 MK3S is capable of printing several materials including but not limited to PLA (and any PLA composite), TPU, PETG, Nylon, and ASA. For a complete list of materials please speak with a technician. Please note that materials the lab does not already have on hand must be ordered and can take several weeks to arrive. Please check with a lab technician for specific material availability.
Build Size
The Original Prusa i3 MK3S has a build area of 9.84 inches in length by 8.3 inches in width by 8.3 inches in height. (25 x 21 x 21 centimeters)
Flat Surfaces
The Original Prusa i3 MK3S requires a flat surface on a model to use as a base, otherwise large amounts of model material will be needed to support it.
PLA Material Cost
The PLA material for the Prusa cost 0.017 $/gram however due to slight losses in the printer purging its head and other operations, use 0.02 $/gram when estimating model cost. Note that models that need to be solid will use this much material, however models that are only for display purposes or can otherwise be printed hollow will not use as much material.
Also note that models with complex geometries and overhangs will need extra material added to the outside of the part as supports. This can increase the costs.
Other Materials
Due to the variety of materials available, please check with a technician for costing information.
Prusa printers have the ability to support all overhangs with model material. This means that any overhangs will need to be supported with a lattice structure made from model material.
Prusa printers have the ability to do unsupported overhangs of up to 45°. This means that, if possible, any overhangs should have a 45° chamfer under them.
Prusa printers also have the ability to “bridge” gaps. Figure 1 – bridge, depicts gaps that were created using the bridge functionality. Please note that long bridges will sag.
