An elephant in a china shop: 3D printers with a huge print field
Over time, everyone is faced with the need to produce large parts using additive technologies. And household 3D printers, in their bulk, have a relatively small table for printing (a square with a side of 180 .... 220 mm). Not much. What to do if you want more?
There are various interesting solutions for increasing print sizes, including huge expensive industrial printers, but there are also budget options for printing at home.
Greetings to all!
I propose to see a selection of 3D printers with a large working field. The selection includes models with a print field of 300x300 to 400x400 mm. The height of the models is also up to 400 mm. All printers are relatively inexpensive, the price range in the article is from $ 289 to $ 599 for branded models, which is quite good for using the printer at home, in the office or for a small business.
This is an interesting 3D classic layout printer with a heated table. Printing with popular materials is possible: PLA, ABS, PVA, PP, wood and so on. Printing comfort provides a large 2.8 "touch screen with support for memory cards and USB drives.

I attach a small video review of the printer - last time they asked for additional information on the models.
The printer is large, comes partially disassembled (removed vertical portal). The assembly is simple to ugliness and takes a minimum of time. The printer is already flashed and configured, just set (check) the table by level and start the test print. Provided for auto calibration.
This model is slightly more expensive, it has a slightly larger print area (320 x 320 x 420mm). Of the important "chips" I note support for Wi-Fi connections and work through the EasyPrint 3D application from a PC, tablet and smartphone. To increase adhesion, a special glass, similar to Ultrabase, is installed on the table (silicon carbide glass with a special matte finish). As a self-calibration, a 3D touch sensor is provided. I note the presence of the filament sensor. If the spool of thread has run out, the printer will simply pause. After the “refill” printing will continue.

Brand: Geeetech Type: DIY Model: A30 Frame material: Aluminum Nozzle diameter: 0.4mm Product forming size: 320 x 320 x 420mm Memory card offline print: TF card Print speed: 80 - 110mm / s File format: G-code, OBJ, STL XY-axis positioning accuracy: 0.011mm Z-axis positioning accuracy: 0.0025mm System support: Windows, MAC, Linux Size: Large Connector Type: SD card, USB
I also note that this 3D printer also requires partial assembly. The list of printer functions is represented by the icons below.
Probably the most popular large printer from Creality3D.
Brand: Creality3D Type: DIY Model: CR - 10S Pro Frame material: Aluminum Product forming size: 300 x 300 x 400mm Molding Technology: FDM Printing Speed: ≤180mm / s, ordinary printing speed 30 - 60mm / s Print Accuracy: ± 0.1mm Printing Height: 0.1 - 0.4mm Nozzle Number: 1 Nozzle Temperature: ≤260 ° C Hot Bed Temperature: ≤110 ° C Working Mode: print online or offline with a TF card File Format: STL, OBI, AMF Power Supply Parameters: 100 - 240V 5.9A 50 / 60Hz input, DC 24V 21A output Printing Power: 480W Printing Material: PLA, ABS, PVA, PP, wood filled, etc. Consumable Diameter: 1.75mm
The layout is quite convenient - the power supply and control unit is built into the “bottom” of the printer, and does not occupy a separate place on the table. There is also a filament sensor, pause and print recovery, and a touchscreen display.
Regarding the qualitative differences, I would like to note the presence of a special extruder with double gear (Geared extruder), which ensures a steady supply of even soft plastics.
Specifications: Brand Name: Anet Type: DIY Nozzle quantity: Single Nozzle diameter: 0.4mm Nozzle temperature: Room temperature to 250 degree Product forming size: 300 x 300 x 350mm Layer thickness: 0.1-0.4mm Memory card offline print: TF card LCD Screen: Yes Print speed: 10 - 120mm / s Supporting material: ABS, HIPS, PA, Wood, PETG, PLA Material diameter: 1.75mm Language: Chinese, English File format: G-code, JPG, OBJ, STL Model supporting function: Yes XY-axis positioning accuracy: 0.012mm Z-axis positioning accuracy: 0.004mm Voltage: 24V Working Power: 220V / 110V / 360W Host computer software: Cura Packing Type: unassembled packing System support: Windows, Mac OS Voltage Range: 100-240V Current (mA): 15A Connector Type: TF card, USB
This printer is the only one that has cylindrical guides, and also comes unassembled. Unlike the usual Anet A8, this model already has a number of improvements that improve the rigidity of the frame and print quality as a whole. The print area is 300 x 300 x 350 mm.
In any case, the presented printers will help in case you need to print a lot in every sense. The built-in print pause will help out when the coil is replaced, when power is lost (the printer will continue to print from the point of stop), as well as in the case of layer-by-layer color printing. Pre-assembled printers allow you to print "from a cold start," it just takes time to install and fix the vertical part (portal), as well as the connection of electronics. It is recommended to level the table before printing. Models with adhesive coating is preferable, since the edges stick off is especially important when printing large models. In this regard, Geeetech A30 looks great with special tempered glass.
