The Ender 5 and Ender 5 Pro are a major design departure from the Ender 3, improving upon the former's bed flinger design by utilizing a rigid open frame that delivers more detailed prints. The lack of automatic bed leveling keeps the price low, and given the spotty performance of low-price automatic bed levelers, we think its a smart decision to stick with the manual process in this price range.
Although the printer is inexpensive, it required some major enclosure design features. First, the power supply and electronics are inside a case, which means 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, where the air is heated up and then kept inside the enclosure. The power of the input and output fans are matched to keep a negative pressure while maintaining good temperatures for both PLA and ABS.
The placement of the display was a major problem being on the far right so it would be impractical to access through a door. Instead, it's mounted on the outside of the enclosure so it's easy to control the print without opening any doors.
It's easy to load up filament thanks to the swinging right-side door that's in exactly the right spot. The door not only makes it easy to load filament but leaves a slit to feed in filament from outside of the enclosure.
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)
High quality acrylic manufactured in Columbus, Ohio
The enclosure box/case/cover 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.
Internal temperatures during printing with the fan turned on:
ABS is 36C to 38C. PLA is 32C to 34C.
Direct Drive Conversions
The enclosure is a full four inches taller than it needs to be for a stock configuration to accommodate all of the direct drive conversion options out there. Note that all enclosed direct drive conversions for H-frame printers like the Ender 5 require a reverse Bowden.
Print Your Own Connector Pieces. Or Not.
A lot of customers prefer to print their own connector pieces themselves. We get it: you've got a great 3D printer, and it is itching to print things. No problem! The kit includes the STLs for all 3D printed parts. Typically it takes about 48 hours to print everything you'll need with a .4mm nozzle and .2mm layer height.
On the other hand, if you purchase the optional connector kit, all parts are 3D printed in the best quality American-made ABS. It not only will withstand the heat year after year, but it's also one of the most rigid plastics to add that will make the enclosure sturdier. We proudly use the best ABS filament you can buy from Atomic Filament in Indiana.
DON'T USE PLA!
The catch-22 is you need an enclosure to print ABS! If you don't already have an enclosure, you can make do with PETG. Just keep in mind that PETG is more flexible and will make the entire enclosure a little less rigid than if you had used ABS. If you still want to print your own parts, just remember that temperatures inside an enclosure will melt PLA, so you will get the best results with printing parts in a high-quality ABS.
Pro Quality American Made Acrylic
The panels are made in a factory in Ohio and cut on an American-built 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 entry-level model has all 3mm acrylic and is a great option for a hobbyist on a budget.
6mm Front and Top, 3mm Sides
The most popular model has a 6mm front and top with 3mm sides. The thicker front is a big improvement for the door. This configuration works great for customers who expect more heavy use such as libraries or schools.
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.
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.
