Will your part fit the printer?
Updated
Build volume is the box the nozzle can reach, in millimeters. Your part has to fit inside it, turned any way you like on the bed, with its height under the build height. Type your part in and the checker lists which printers can hold it.
Will your part fit? Check it against each printer's build area
Build sizes are the listing numbers. The check lets the part turn 90 degrees on the bed, keeps the height as you entered it, and does not try diagonal placement. A part within 5 mm of a limit is marked tight, because a brim or skirt needs room too. This is a size check, not a promise that the print will succeed.
Common parts, checked
| Part | Size (L x W x H) | A1 mini (180 cube) | Adventurer 5M (220 cube) | Ender 3 V3 SE (220 x 220 x 250) | A1, P1S, Centauri Carbon (256 cube) |
|---|---|---|---|---|---|
| Phone stand | 90 x 80 x 110 mm | Fits | Fits | Fits | Fits |
| Tall vase | 120 x 120 x 200 mm | No | Fits | Fits | Fits |
| Lamp shade | 150 x 150 x 240 mm | No | No | Fits | Fits |
| Drawer organizer | 230 x 150 x 40 mm | No | No | No | Fits |
| Half of a costume helmet | 240 x 200 x 230 mm | No | No | No | Fits |
| One piece sword blade | 600 x 60 x 20 mm | No | No | No | No |
These rows use the same rule as the checker. The part sizes are examples, not real models. Look up your own in the slicer or on the model page.
- A1 mini5.8 liters
- Adventurer 5M10.6 liters
- Ender 3 V3 SE12.1 liters
- A1, P1S, Centauri Carbon16.8 liters
What the numbers leave out
- Height is its own limit. The Ender 3 V3 SE is 220 mm wide but 250 mm tall, so a tall lamp shade fits it and not the Adventurer 5M.
- Big flat parts can warp. Prusa's PLA page says PLA can fill almost the whole print volume and is not prone to significant warping. Bambu Lab's A1 FAQ warns that ABS and ASA on an open printer bring bigger warping risks on large models.
- Leave a margin. A brim or a purge line needs a few millimeters. The checker marks anything within 5 mm of a limit as tight.
- Too big is not the end. Most slicers can cut a model into pieces you glue together. A sword blade that is 600 mm long gets split on any printer here.
Which size to buy
- Mostly small toys, clips and figures: the Bambu Lab A1 mini is enough. Caveat: nothing over 180 mm in any direction.
- Household parts, organizers, vases: the Bambu Lab A1 with its 256 mm cube. Caveat: open frame, so PLA and PETG, not ABS.
- Same size but ABS or ASA: the Bambu Lab P1S. Caveat: the AMS for multi-color is extra.
