Creality introduced a new desktop 3D printer, the Ender-3 V3, which has a feature I’ve never seen before.
The company has produced countless variations of the popular Ender-3 device, and we even have several around our lab. However, all of them use the basic i3-style design.
The new Ender-3 V3 is a “CoreXZ” printer. Nope, I didn’t mean “CoreXY”, it’s actually “CoreXZ”.
CoreXY is an ingenious way to use a series of belts to reduce toolhead weight, synchronize two axes of motion perfectly, and reduce the cost of the motion system. The concept is essentially two dimensional, and most 3D printer manufacturers use it for the XY part of the motion system, leaving the Z axis running separately.
Here, however, Creality has done something quite different. Instead of “Core-ing” the XY plane, they instead are using the XZ plane. There won’t be threaded rods on this system, as the Z-axis is part of the belt system that works the X-axis.
Worried about dealing with more belts? Will these belts slip? Apparently not: Creality has designed the CoreXZ system to tension belts automatically. They say you will not see belt slips or shifts on this machine.
Why do this? It’s all about speed. CoreXY systems are able to use vibration compensation and other features to achieve enormous print speeds. However, CoreXY systems typically have four structural corners to accommodate the CoreXY motion system. Typical i3-style systems can’t really do this.
Creality here has flipped the plane to XZ and thus are able to build a high-performance motion system in the typical i3 hardware style.
Creality said the new device will be able to achieve 600mm/s 3D printing, and has a volumetric deposition rate of 32 cubic mm/s. There’s an accelerometer on board the toolhead, which allows the Ender-3 V3 to self-calibrate for high speed movements. After calibration it can run at a whopping 10,000 mm/s/s acceleration.
The CoreXZ motion system should greatly reduce Z-axis wobbles, something that can corrupt print quality on standard machines.
There’s more to the device.
The gantry and base are die-cast metal, making them extremely rigid. This will assist in high speed printing, as vibrations will be dampened. Even the cover is die-cast aluminum, making this machine a step up over plastic competitors.
The Ender-3 V3 has a new extruder and hot end, which permits quick swaps for alternative diameters. The hot end is powered by 60W, which is sufficient to handle the higher flow of material. Beefy dual cooling fans can easily keep up with the high speed printing.
The extruder seems to be new as well, and it has been designed to be clog free for long periods. If it works as well as their Sprite extruder, everyone will be quite happy.
The quick-swap nozzle, called “Unicorn”, is quite interesting. It is actually a combination of the hot end and heat break, meaning that the possibility of leaks is vastly diminished. It can reach 300C, allowing the use of many engineering materials.
The result of all this is high quality, high speed 3D printing. Creality said they can complete an excellent quality #3DBenchy in only 13 minutes.
The controller on the Ender-3 V3 is a 1.2Ghz dual core board that runs a variation of Klipper, which is well-known for its ability to perform high speed 3D printing. There’s WiFi connectivity for remote monitoring and control. However, the webcam is an optional feature.
Creality also will offer an optional enclosure that could be useful for 3D printing higher temperature materials like ABS, ASA and nylon.
As you might expect, the Ender-3 V3 includes fully automated calibration, greatly simplifying operation. Those who are still using the original Ender-3 model will be amazed at what this system can do all by itself.
Like most Creality systems, the Ender-3 V3 is shipped flat and requires some assembly. However, from the looks of this image it seems that the assembly process is minimal.
The Ender-3 V3 CoreXZ 3D printer is available to purchase now, and it has a very good price of only US$389.
