The Ender 5 Plus is the larger, better cousin of the Ender 5. Gone is the cantilevered bed, replaced by dual Z-motors with stabilizers on all for corners. Instead of manual bed leveling, the included BLTouch gives a perfect first layer every time.
But the part that's most exciting to use at 3DUPFitters is what's the same for the entire Ender series: they are perfect for enclosing in a box/case/cover. While keeping the electronics cool is problematic (more on that later) keeping the hot end at the top means a consistent enclosure temperature. As the printed piece gets larger, the previously printed section of the part moves lower, but the enclosure also heats up. In the end, it's much easier to print large parts in temperature-sensitive filament such as ABS while avoiding warping and cracking.
The biggest design challenge of enclosing the Ender 5 Plus is the power supply and electronics are inside a case. If you just stick the printer in a box it will overheat. Instead, we custom designed an air scoop that brings in cold air to the power supply and electronics, keeping them cool no matter the temperature inside the enclosure. The airflow keeps a mild negative pressure while maintaining good temperatures for both PLA and ABS.
The one weird thing about the Ender 5 Plus is the placement of the spool holder on the back. We designed three different prototypes, each trying to make it easier depending on how you like to access the printer. If you've got enough room to walk behind the printer there's a large access door to load and unload filament or work on the extruder. If you don't, we made the front door tall enough with enough clearance that you can easily access the bed OR replace the filament from that direction as well.
Direct Drive Conversions
Lots of customers are modifying their Ender 5 Plus printers, and we've designed this enclosure with that in mind. There is plenty of room at the top of all sorts of 3rd party hot ends that those from Bondtech and MicroSwiss. But you'll definitely want to read this discussion of the ins and outs of using an enclosure with an H-frame printer converted to direct drive.
Advantages of adding a 3DUPfitters enclosure:
Better quality prints because the ambient temperature is controlled
Keeps the power supply cool while the interior is hot enough for consistent prints with advanced material
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. If your main concern is the smell of melting plastic, it can be mitigated using an optional carbon filter. But if you are more interested in improving overall indoor air quality, a better solution is to vent to the outside via a hose. (not included). If you just want the highest possible enclosure temperature for ABS just put on the included air vent cover and it'll heat up as hot as possible.

How it's 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 to put it together is a hex wrench and a small Phillips head screwdriver. (not included.)
The base enclosure has a 6mm front and 3mm sides. This configuration has been in production for years and works fine with hobby use and 1Kg filament spools.
If you want to use 3Kg+ spools on top of the enclosure then the 6mm top upgrade is a good idea. This is the configuration we use in our print farm and it works great.
If you want to gain a couple of degrees of heat retention or intend to move your enclosure around a lot you can't go wrong with the 6mm all-around option. Note that if you choose that option you don't also have to purchase the 6mm top upgrade.
