Finding the Right Size 3D Printer: It’s Simpler Than You Think
Choosing a 3D printer can feel overwhelming, but determining the right size is surprisingly straightforward. There are really only three key things to consider.
The “Default” Size: Why 220x220x250mm Matters
The Creality Ender 3 is often cited as the most popular 3D printer ever made. Its 220x220x250 mm build volume has significantly influenced the 3D modeling community, becoming a common size for models shared on platforms like Printables, MakerWorld, and Thingiverse.
Scaling models up or down is possible, but most 3D printer owners have a printer around this size, meaning you’ll rarely encounter models requiring a significantly larger build volume.
The Rise of 256x256x256mm
While the Ender 3 popularized a specific size, Bambu Lab has gained traction with a slightly larger 256x256x256 mm build volume, found in models like the A1, X1C, and P2S. Prusa’s Core One+ offers a similar 250x220x270mm volume, and Creality’s K2 manages 260x260x260mm. A clear trend has emerged: “Ender 3 or slightly larger” seems to be the sweet spot for many buyers.
This size strikes a balance – it’s large enough for many projects without being overly bulky for home apply.
What Are You Planning to Print?
Most users print relatively small items. If you’re considering large, one-piece prints like cosplay helmets, large vases, or oversized custom models, a larger printer is beneficial. However, many popular and useful prints are smaller.
Smaller prints require less filament and print faster. Many models are designed to be easily printed on “Ender 3 or slightly larger” printers.
Don’t Dismiss Smaller Printers
Space and budget constraints may lead you to consider smaller printers like the Bambu Lab A1 mini or Prusa Mini+. These have a build volume of 180x180x180mm. If this fits your needs, it’s a perfectly viable option.
Platforms like MakerWorld and Printables allow filtering by printer type, with models available for smaller printers.
Frequently Asked Questions
- What size 3D printer should I buy? A 220x220x250mm or 256x256x256mm printer is a good starting point for most users.
- Are smaller printers worth it? If space or budget is limited, a smaller printer like the Bambu Lab A1 mini or Prusa Mini+ can be a great option.
- Does build volume affect print quality? Not directly. Print quality depends on factors like nozzle size, layer height, and filament type.
Remember to tread carefully when considering a second-hand printer.
