The Creality CR-M4 is a versatile 3D printer that offers exceptional precision and build quality. It's engineered to handle a range of materials, including ABS, PLA, PETG, and TPU, making it suitable for a wider range of applications than most printers.
With a print bed measuring in at 17.7 x 17.7 x 18.5 inches (450 x 450 x 470 mm), the Creality CR-M4 is one of the largest 3D printers we've ever tested. In fact, it's too big for most users who just want to print average files. However, if you're looking to print truly massive models, such as whole armor pieces for cosplay or huge terrain pieces for wargaming, then it might just be the best 3D printer for you... if you can afford the price tag.
In this review, we'll delve deeper into the CR-M4's features, capabilities, and overall performance to help you determine if it's the one for you.
When setting up the Creality CR-M4, there are only a few simple steps to follow. This printer, like many other Cartesian-style printers available today, is relatively easy to assemble. The first step is to attach the upright assembly onto the base. This assembly consists of the vertical supports that will hold the printer's moving parts in place.
Once you have attached the upright assembly, the next step is to attach the upright stabilizing tubes. These tubes are important for ensuring that the printer's moving parts are held securely in place, and that the printer operates smoothly and accurately.
After you have attached the stabilizing tubes, you can move on to attaching the cable chains. These chains contain all the wiring for the printer's motors, as well as the direct drive system. Each cable is clearly labeled, so you can easily tell which wire goes where.
Once you have attached the cable chains, you can attach the touch screen. This 4.3-inch screen is an important component of the printer's user interface and allows you to control the printer's settings and monitor its progress during printing.
Finally, you will need to clip the filament spool holder and filament runout sensor onto the top of the printer. These ensure that the printer can feed filament smoothly and without interruption during printing.

Once you have completed these steps, it is important to check all the belts and wheels to make sure that they are snug and secure. Any loose belts or wheels can cause the printer to operate poorly and result in low-quality prints or even damage to the machine. By making sure that everything is tight and properly aligned, you can help ensure that your printer operates smoothly and produces high-quality prints every time.
Creality has mostly stuck to their standard design for the CR-M4, with one major change: The classic V-slot wheels on the print platform have been replaced with two CNC machined linear rails, which are much more stable and offer smoother motion than the classic wheel design. We’ve been seeing this a lot recently, with the Anycubic Kobra 2 also making the jump to linear rails. Additionally, the single spool holder has been modified to allow for the mounting of two spools, making swapping them out quick and easy.
The CR-M4 also features a PC-coated spring steel removable platform that provides excellent adhesion, but still allows for easy removal of prints once the bed has cooled. The 4.3-inch touch screen follows Creality's classic design, with a clear and simple menu system that makes it easy to tune, load, and monitor print progress.
The CR-M4 has a large build volume of 450 x 450 x 470 mm, which means you can print larger objects or multiple items in a single print run. It's also equipped with a magnetic removable PC spring steel bed, which ensures that your prints adhere to the build plate and reduces the risk of the part coming off mid print.

The CR-M4 3D printer utilizes a unique design that features two Z-axis and support rods that work together to create a sturdy triangular formation. This formation provides a stable top frame that is essential for precise and accurate movements during the printing process. The printer's dual Z-axis system(equipped with independent motors) ensures that both the gantry and Z-axis remain level and free from sagging, which can compromise the quality of the final printed product.
Thanks to these changes it delivers exceptional printing performance, resulting in visually appealing and high-quality models. The precise and accurate movements of the printer's dual Z-axis system, coupled with its stable top frame, make it possible to produce intricate details and smooth surfaces that are almost entirely free from imperfections.
Another standout feature of the CR-M4 is its user-friendly interface, which makes it easy to set up, navigate, and customize your prints. Whether you're a professional looking for a reliable 3D printer for your business or an enthusiast looking to take your 3D printing to the next level, the Creality CR-M4 is an excellent choice.
In terms of connectivity, the CR-M4 offers both WiFi connectivity and a LAN port. This allows users to monitor, slice, and load prints using the Creality Cloud app or site. You can also transfer files to it via USB drive. Additionally, an optional camera is available to make monitoring prints even easier. This camera can be simply plugged into the USB port on the side of the printer by the LAN port.
Overall, the CR-M4 offers some significant improvements over previous models, particularly in terms of stability and motion. The addition of a removable print platform and dual spool holder also makes it more user-friendly and versatile. Plus, with the ability to monitor and control prints remotely, as well as an optional camera, we think the CR-M4 is a great choice for both beginners and experienced users alike.
For our first print on the Creality CR-M4, we decided to print a simple vase, but at 350% of the normal size. The vase used nearly all of the printer's height, measuring 17.5-inches tall. We used Giantarm Silk Rainbow PLA for the print, which took approximately 12 hours in vase mode at a 0.2 mm layer height. The purpose of this print was to test the printer's large print volume, which measures at a massive 450 x 450 x 470 mm.
Due to the size of the print, the vase ended up looking more like a large bucket than a traditional vase. However, this simple print allowed us to see just how large the CR-M4's print volume really is. The Giantarm Silk Rainbow PLA we used for the print is a high-quality filament that produced a smooth, glossy finish on the vase, even at this large scale. Overall, the CR-M4 handled the print well and produced a high-quality result.
For our second print, we decided to print an amazing Azure Cloud Wyrm designed by Jukka Seppänen from his MyMiniFactory store. We scaled the model up to 200% and used Eryone Silk Dual color Green and Black PLA. With a layer height of 0.2 mm and 5% gyroid infill, the print took 59 hours to complete.
The results were simply amazing. The dual color PLA printed perfectly, with the front half of the print in a bright green and the back side in a nice silk black color. The overall effect is stunning, making for a truly impressive print. The Eryone Silk Dual color PLA is a high-quality filament that provided a smooth finish on the print and allowed for great color separation between the green and black sections.
Despite the print taking a significant amount of time, the CR-M4 handled it with ease and produced a high-quality result. The combination of the dual color PLA and the intricate design of the Azure Cloud Wyrm made for a truly eye-catching print. The designer, Jukka Seppänen, did a fantastic job creating this model and the CR-M4 did a great job bringing it to life.
For our final prints, we chose to print a pair of busts from Eastman and his Patreon. Specifically, we printed the Batman 1990 and Joker busts, using Black Matte PLA and a layer height of 0.2 mm at 100 mm/s. The two busts and stand for Batman took just under 26 hours to complete.
The prints came out fantastic with no issues, and all the details were clearly represented. The CR-M4 performed admirably, with no stringing while the hot end moved from part to part, showcasing the excellent performance of the Sprite direct drive. The Black Matte PLA provided a smooth, clean finish on the busts, with no visible layer lines.
Printing busts like these can be challenging due to the high level of detail required, but the CR-M4 handled the job with ease, producing impressive results. The busts are a testament to the capabilities of the CR-M4 and the high-quality of the prints produced by this machine. Overall, we were very pleased with the performance of the CR-M4 and the quality of the prints it produced.
