Creality had success with their huge CR-10 S5 printer, but apparently that was just a tad too large, so they created the slightly smaller CR-10 Max. This time, though they threw in bed leveling, put in a bed heater than covers the entire bed, updated the hot end to their most recent design, and made a bunch of smaller improvements.
Even though the CR-10 Max is smaller than the S5 at a build volume of (450x450x470mm), it's still an enormous printer. This creates problems when designing an enclosure because the same design that works for the much smaller CR-10S doesn't work here. For starters, the 1/8" acrylic isn't sturdy enough for a box that large, so we doubled its thickness to 1/4". This, unfortunately, raises the price of the acrylic, as well as the weight, but it is extra sturdy and durable for industrial and educational use. The enclosure comes flat packed, but it is still so large and heavy we have to build custom crates to make sure it gets to you safely.
Another problem is the front is no longer a convenient way to feed filament since the printer is so deep. Instead, a side-door has been added at just the right location to be convenient. The filament feeds right through a slit in the middle of the two doors, and a side-top-mounted spool holder makes sure the filament goes into the extruder at the right angle.
To keep the electronics cool a custom vent has been added to the side. Together with the 80mm fan, a stream of cool air is brought into the electronics case where it is heated by the CPU board and power supply and then circulates through the case before exiting out of the back fan.
One of the challenges with a passively heated printer enclosure this large is managing the internal temperature. The temperature at the bottom of the enclosure isn't the same as at the top. Here's what you can expect with the two most common bed temperatures. Unfortunately, the CR-10 Max isn't great for ABS right out of the box. For example, the default plastic bed covering warps at 110C causing the bed leveling to fail. We upgraded to a steel bed plate. Another modification we like to do is upgrade the bed heater and then run it at higher temperatures up to 125C, or you can DIY a bathroom heater. Note that the later modifications are only suitable for a qualified electrician or electrical engineer.
Adding a 3DUPfitters enclosure provides many benefits:
More flexibility to print different types of filaments, including ABS
Better quality prints because the ambient temperature is controlled
Fume filter to reduce smell or vent to the outside (sold separately)
Sturdy, thick, high-grade acrylic doors for easy access
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.
