The Prusa i3 line is based on the RepRap open source hardware, but has the capabilities, fit and finish, and attention to detail of a much more expensive printer. In a market awash with inexpensive printers full of crappy parts that wear out quickly, everything about the Prusa i3 is quality: a hot end that can print anything, a best-in-market removable bed, and a slicer tuned to make the most of the printer.
The only thing the Prusa lacks is an enclosure to make full use of its capabilities, as well as retain the smells and air contaminates from melting plastics. This is a professional-grade, cool-looking enclosure you can assemble in about an hour, and works with a perfectly stock Prusa i3: no modifications needed.
Advantages of adding a 3DUPfitters enclosure:
Better quality prints because the ambient temperature is controller
Provides cool air to the power supply with no modifications to the printer
More flexibility to print different types of filaments, including ABS
Optional fume filter or vent to the outside (both sold separately)
Thick 6mm acrylic doors and 3mm sides
The enclosure works by retaining the heat from the bed to bring the ambient temperature up high enough so that ABS and other filaments that expand when they cool are stabilized. Included is an optional fan will draw cool air across the power supply where it is heated by the supply, and then gently circulate throughout the enclosure (providing a steady air temperature). From there the air can be vented into the room, sent through an optional air filter (not included) or vented to the outside via a hose. (not included)
Note that because of the close tolerance around the power supply, the height of the printer must be stock for the MK3 with its rubber feet. The MK2 will also fit, but getting it to be the correct height will involve the user of one of the many feet available on Thingiverse.
How its Built
All of the plastic parts are 3D printed in ABS to withstand the heat from the enclosure. The panels are cut on a US-made industrial laser and then flat packed for your assembly. All you need for assembly is just a hex wrench and a small philips head screwdriver. (not included.)
The outside venting system will send potentially dangerous and definitely odorous fumes outside. We supply the fan and 4" dryer hose adapter, you get the rest of the parts from your local hardware store.
