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 almost immediately, 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. Sure, there is an official DIY Lack enclosure design, but it requires a trip to Ikea and the hardware store, and then dozens of hours of construction, plus modification of your printer.
If you're a school or business and don't have the time for DIY, or simply would rather be printing, this is a professional-grade, cool-looking solution 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 to reduce smell or vent to the outside (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. If you add the optional charcoal air filter, the fan will draw cool air across the power supply where it is heated by the supply, and then gently circulated throughout the enclosure (providing a steady air temperature) and then out through the filter to reduce smells.
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. Theoretically the MK2 will also work, 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, printed as much as possible on the Fusion3D F400, but also on upgraded FT-5 and CR-10 printers. The panels are cut on a CNC or 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.
Interior LEDs (as pictured in the wood & acrylic version renderings) will make it easier to see prints inside the wood version.
